Subaru Outback

"It plays when it wants to"

"Touchscreen often doesnt connect to my Apple CarPlay."

"Apple Car Play frequently quit or will not restart"

"Navigation from Car Play didn't work when I upgraded to iPhone 16 Pro. The service technician advised that it was the after market USB cord and I needed an "authorized" Apple USB Cord. I purchased the Apple cord and it solved the problem."

"Would not pair. Subaru wanted to charge me for an evaluation even though it was common knowledge these cars had infotainment problems."

""There was a fuse that broke and drained my car battery, but when it was disconnected, my CarPlay didn't work right. It was later recalled and replaced.""

"Whistle speaking on the phone. Sometimes it disconnects call altogether. Other times. You can hear the person speaking or vice versa."

"Consistent problems with Apple CarPlay not pairing, will quit working randomly, generally a pain. Had radio replaced but Apple CarPlay issues remain."

""The screen would be blank. Screen would freeze. Would lose function. Could not use GPS, Texting, Phone calls. To fix they had to replace the radio. Cost me 750 including labor. Subaru provided me transportation home . The driver told me everyone was having that done. Very common. Information from subaru employee, newer cars than mine were having same issue and for those cars more expensive.""

"The screen was blank, the radio did not work, and the phone interface did not work all of a sudden. By disconnecting the battery and reattaching, it the problems were solved."

"Won't start at the beginning of the CD or play all the way to the end. Hard to advance or reverse to get to the start. Didn't have these problems with the same CDs in my 2011 Outback. I've asked the dealer twice and they say they can't find a problem or it's with the CD itself."

"Multi media system had to be replace as it was no longer functional. It was covered by warranty even though the standard 3 year warrany had expired."

""Infotainment system lost its mind. Bounces through all available screens rapidly and none of functions work (GPS, radio, Bluetooth, maps, music, etc). Dealer said repair would be $3000. Nine months later Subaru extended warranty for infotainment system""

"It froze up periodically and then consistently"

"Strange "bubbles" under the glass formed and would result in the screen having a mind of it's own and clicking randomly. Had to replace the whole unit."

"At times I would attempt to listen to incoming texts and the screen would just freeze on the inbox. Would not let you answer the phone or even go to Apps"

"Screen will often not respond to touch or button controls, makes its own changes, says theres moisture in my phone port for no reason, will not reset, sometimes goes completely blank and will not come on even when I restart the car, often does not pair with my phone lately (same phone), connects to phone but does not engage all apps."

""The display screen would freeze up, switch screens randomly, bubbles on screen.""

""One must power off the display screen while car is running. This can be done by pushing and holding the volume button, which forces the display screen/ radio to reboot. (I don't think most consumers are aware of this reset option.) It seems like the radio head units (which includes the display screens) are a known problem with this generation of Subarus""

"There is a well known failure of the display screen failing. Subaru has extended the warranty to cover replacement of the entire unit if necessary."

"Problem occurred twice within 2 last years. Display screen was inoperative, at times screen were missing data and pixelated. Screen and data would freeze and were not available for periods of 2-3 hours."

"Every couple months the unit will not let me change screens. It freezes up.After several hours it responds again"

"When I would be listening to the radio the screen would start flashing and moving from one app to another and then the screen would freeze."

"The display screen has never worked. I got the car with 56000 miles and it was not working then. I am replacing the whole head unit soon."

"Infotainment unit has the common de-lamination problem which has left the touch screen useless. The de-lamination (bubbling) started about 12 months ago but did not interfere with the system. About 9 month ago we started getting phantom touches. Phantom touches are where the screen will randomly act as though someone has touched it. This causes problems where the audio will change source, for example start scanning or changing radio stations. Or if a map/gps screen is up it will add a new destination due to a touch on the screen. It was not covered under warranty appox 6 mo ago when last at the dealer. In the past 3-6 months the unit has been unusable due to the frequency of the phantom touches. Subaru of America just notified us the warranty has been extended. Have not had a chance to have the dealer evaluate or replace it."

"Bubbles formed under the touch screen which made it unusable. After Subaru said it wasn't under warranty and they wouldn't help with it, I replaced it with a Sony after market system. About 6 months after that, Subaru acknowledged there were problems with the unit, and they extended the warranty. However, since I no longer had the defective unit, they wouldn't do anything. No a good answer and they have likely lost me as a loyal Subaru owner."

"The display screen froze up on a long trip while using navigation. took it to the dealer and the manufacturer replaced it outside of warranty."

"Touch screen became unresponsive to touches. Screen then delaminated. Dealer replaced entertainment unit. Unit didn't work. Still waiting for replacement after 6 months. Removing fuse for dcm deactivated several unit of unit."

"Started on a trip out of state. Unable to use anything related to the main radio/ GPS unit. Was replaced underneath the extended warranty. It didn't end up costing me anything, but it would have been a couple of thousand."

""experienced de-lamination and it looked like the factory stereo had water or oil between the display. Was unable to make input/output. Totally broken. Replaced with after market stereo. Subaru would not cover this even though it is a known problem on 2018 models. It wouldn't cover it as it was a 2019 model. class action law suit in the USA regarding this, but not in Canada.""

"Actually the screen switches between all of the different displays. It happens daily. I keep the display turned off."

"the touchscreen became unresponsive"

"At first the unit would randomly beep. This increased until the unit screen eventually went dark. The unit now beeps and flashes continuously. We have not taken it in to the dealer to have it replaced yet. Subaru has extended the warrant to cover replacement as this is a widespread problem with this year's make and model."

"The Display screen has never worked"

""It started during/immediately after a standard mile based service.I noticed as I was driving away and went back to prove it to them. After they coordinated with the main company they replaced it for free. With the new unit it often has problems with talk to text link to Apple phone. Rather than initiate a text I now reply to an existing text from the person I want to text with. Otherwise it works fine. The replacement was 3 hour wait at dealer but now does Waze mapping just fine,""

"Display screen is basically invisible in the daytime because of the way its slanted, catching constant glare."

"Intermittent in September 2024. Dealer fixed right away. Just got notice that there is a recall for this issue and I will be reimbursed"

"the media center stopped working l"

"Display starting blinking and freezing up."

"see previous answer."

"Blue tooth pairing doesnt always stay synched with iPhone"

"Screen delaminated access and was replaced with new unit that didn't work. Display shows me being about 80 miles from my actual position. Removing dcm fuse deactivated several functions from unit. Still waiting for replacement after 6 months with no status communication from dealer."

""Screen acted erratically, many times non-functional. Because I had purchased an extended warranty, the system was replace for the cost of the $100 deductible.""

"Infotainment system screen malfunction. Took 6 months (back order) to get new one."

""Built in screen with radio, GPS, camera, mpg reading, speed control, clock, addresses and other built-in components quit working""

""I had issues with the Harmon Cardon infotainment system since the software upgrade to eliminate 3G which was draining the battery. No CarPlay, system had air bubbles and went crazy (flashing lights, no radio, no pairing, could not even turn it off). After 2 months at the dealer, the head unit was replaced but has already had a problem and I found out it was replaced with a refurbished unit.""

"Replace DCM due to battery drain."

""The entertainment system had to be replaced; it no longer displayed any information, and the radio did not work.""

"Vehicle had defective head unit, DCM and parasitic battery drain since purchase. This has resulted in multiple battery replacements, hours lost, time without a vehicle, and inconveniences. Some technicians indicate the replacement of these parts will resolve the issue. Others say it will not be resolved. Some anecdotes report this is an issue with the OnStar system continuously trying to connect to 3G satellites that are no longer functioning."

"After a couple of jumpstarts, the vehicle was brought to the Subaru dealership for to both identify and repair the issue. The 4G SOS and StarLink module located between the eyesight cameras, but on the roof was determined to be the cause of a slow 12V battery drain. This required a new 4G module, as well as a new 12V battery."

"Head unit defective on purchase, have not been able to replace since purchase as part is unavailable. Bluetooth and Apple Carplay dont work due to this."

"screen would not sinc with the current driving system"

"had to be replaced New one has an intermittent problem with pairing for text and phone calls"

"Display screen delaminated and all display functions (radio, navigation, etc.) could not be used. Issue occurred over two months and had to be replaced spring 2025."

""Screen delamonated and the unit did not function properly. It would not accept changes, and it would make changes of apps on its own.""

""Bubbles formed on the touch surface, mist likely from hear and a manufacturing defect. The touchscreen was unresponsive in certain regions of the screen while other regions would activate on its own. Could not control media and the connected phone would automatically dial numbers because of the erratic screen behavior.""

""The "infotainment" center is the source of many annoyances. Bought this 2019 car brand new and in 2022 the batteries started to die. They never lasted a year. Ends-up that the "DCM" (Data Control Module?) for StarLink kept trying to phone home over a 3G wireless connection. 3G technology was retired nationwide, so the DCM frantically kept searching for a signal even when the car was off. Hence the drained batteries. What a short-sighted, terrible, horrible, stupid design decision. In May 2025 Subaru replaced the entire Head (HUD?) unit and DCM. I asked if this now-4G system would drain my battery in the future. Subaru assured me that the new module would not call home. Android Auto has never worked properly since 2019. The Subaru service tech said something about Android Auto in the car not keeping-up with the changes to the AA on the phones. WTF? I keep the car's firmware up to date via Wi-Fi. So it shouldn't take a HUD replacement to update the embedded AA firmware. Another horrible design for which I hope an entire Subaru product management team got fired... instead of promoted for saving some money at the expense of customer satisfaction. Other problems with the infotainment unit included a spastic volume button that jumps too-high or too-low at a gentle touch. Inability to play MP3 files from an inserted thumb drive - and if it does play, loses connection, can't index the files, plays one track and not others, randomly freezes. I've yet to see if the new HUD fixes these issues. While griping about the infotainment. The MP3 player itself has fewer features and is clumsier to use than a 2001 MP3 player! Scrolling menu to select genre, artist, etc. Going "back" in a menu loses your sorting and indexing. Music indexing playback is alphabetic - not by track number - so if you want to play an album, you have to create a Playlist on a computer first.""

""Display acted crazy, switching channels, map location, etc. Subaru eventually fixed it after waiting a long time for replacement part, and reimbursed me for the cost as part of extending the warranty on this part""

"GPS will get me to a general destination but can't always be specific about the exact location. Sometimes it will tell me the destination is on one side of the road when it's actually on the opposite."

"About three years in, the battery started going dead after only two or three days without being driven. Replaced the battery but the problem continued. Eventually learned that this was a known issue with 2019 Subarus. Had to to drive to Grand Junction (three hours away) to get this repaired for free. No problems since."

"As I recall the parasitic battery drain was tied to the navigation system and an internal to Subaru report on the issue finally got it resolved."

"the system would show the car was in the middle of the ocean. It would also turn up the radio or turn it down or off"

"Navigation system stopped working one day. It started working the next day"

"Would not give any directions"

"An electronics issue was causing a parasitic battery drain that took months to resolve."

"Entire system was replaced at no cost due to extended warranty"

""The touchscreen often doesnt work, forcing me to use the knobs to navigate and select options. However, this method is slow, unreliable, and unsafe to use while driving. As a result, I frequently have to rely on the map on my iPhone, which requires holding and looking down, creating a safety hazard.""

"TPMS sensor had to be replaced at a cost of $ 492"

"DCM switch/fuse had to be replaced per recall"

""The starlink system was faulty. This caused it to drain the battery twice, requiring the starlink system be replaced in order to use the vehicle""

""Head unit slowly failed. First navigation map would freeze up getting progressively more frequent and severe. phone communication via in sytem blue tooth and/or Apple Car Play began to fail, getting progressively worse. As time went on head unit would lockup and could not get out of failed mode without restarting car. Head Unit replaced under extended warranty that I had purchased. Since then have received letter from Subaru of America stating "Warranty Extension for certain 2019-2023 Subaru Gen 3.1 and CP1 Infotainment Audio Head Unit". Extended (3) years or (36,000) miles to (8) years or (150,000) whichever occurs first.""

"I have repeatedly tried to update the software but it never works."

"causes screen to blank. fix is to disconnect battery, I did of 30 seconds, and reconnect."

"I initiated an OTA update. I could tell that the update froze the screen. Subsequently, even after I turned the car off, the HUD remained activated. This drained my recently replaced battery. After a jumpstart, I went to the dealer who was able to perform the update. The dealer was going to charge me a $100 deductible, which after discussion was waived."

"Phone pairing woukd nit work properly because speakers were not properly connected and software was not correctly installed when vehicle was delivered."

"The GPS stopped working, possibly because my car wont sync with my Bluetooth phone"

"The GPS does not work"

"Not reliable in connecting all of the time"

"Doesnt always pair either with cord or Bluetooth"

""Several months ago, the pairing of my phone started to fail. In the first step, the screen would light up with the notification, but pressing the button to engage the phone did nothing. Eventually, the announcement stop coming up on the screen altogether. The deal is here in Florida are terrible so Im waiting to go to Rochester, New York to Van Bortal to take care of this. Myself and several friends have tried to fix this. Weve been unable to pair the phone.""

"Calls cannot be answered using the car function. Dealer said it was a software update needed by that did not work"

"Inconsistent and will drop suddenly and driving so you're no longer have access to yyourown Google maps or Waze maps"

"The phone pairing now requires me to add an app to my phone."

"Sometime the phone that was paired is no longer paired and you have to start over"

"Phone pairs via Bluetooth well except that Googlemap commands don't play. Once or twice the only audio prompt I got from maps was "destination is on your right/left," which I already know by then. Subaru blames Verizon, Verizon blames Subaru."

"The car would randomly connect with my phone and initiate calls. Ive removed my phone so that it doesnt randomly connect. While charging it randomly initiates phone calls"

"I have had an internal short that drains the battery. The dealer said the only way to stop is is unpair the bluetooth, so can't use my phone in the car"

"audio cut out. replacing amplifier for $713. Will check to see if covered under extended warranty on audio head unit."

""Like the Mazda, the system is broken. Unlike Mazda, Subaru applied an extended warranty and will replace the unit. Kudo to Subaru. Shame on Mazda.""

"Radio volume button does not function properly. When you turn the volume button the volume just jumps iradically. If you adjust the volume multiple times you can eventually get the volume set to the desired level"

"The entertainment system quit working."

""Display screen started to separate. Returned to dealer who said it was covered under warranty to replace, which it was.""

""Light behind the tuner knob failed. Volume control knob does not function properly, volume will change randomly when volume knob is used. Radio will occasionally not work.""

""several months ago, the radio began to change stations randomly on it's own""

""The radio would switch music input sources. The screen would go blank, and all kinds of weird things would happen. It took until just the last few weeks when we got a recall notice from Subaru.""

"Radio and entertainment console went bad and did not function."

"started 8/4.2025"

"see prior discussion of display screen. The problem appears to be the interface between the touch screen and the underlying radio head unit and it's software"

""When trying to increase or decrease the volumn there seems to be a lag in time, a few seconds between turning nd actually it to register. It might jump from 8 to 3 or 10 to 5. You just never know.""

"Radio was actually going blank and glitching, took it in and they replaced it because I bought an extended warranty. New radio goes up and down in volume sometimes a lot more than if you only want it raised or lowered by a little bit."

"Subaru corrected this problem without me paying for it. My battery drained if I did not use the car for 30 hours."

""Battery lasts less than 2 years. Computer module and that controls battery power distribution,etc.became defective. Both items taken care of under warranty, even though 3 year warranty period had expired.""

"The battery kept discharging due to a rooftop short."

""Car repeatedly died if left sitting for more than 2-3 days. Battery was replaced once then issues continued to occur. Subaru initially did not correctly diagnose (or did not admit to) nature of the problem. Found out about class-action lawsuit over charging system by searching on line, but when replacing the battery did not correct the issue did more searching. Starlink module was continuously searching for a network that no longer existed, causing the battery to drain. Car was unreliable because of this. Subaru eventually sent out a service advisory with a correction to the problem and I was able to get it resolved several months ago. The car is now reliable and I am happy with its performance.""

"The control module has a defect that drains the battery even while off. Subaru extended the warranty and did replace the control module and the problem seems fixed."

"Keeps discharging when driven infrequently. Too many times I've been stuck at home because the car won't start. Then I have to put it on a charger because it's usually too weak to jump."

"Car infotainment system kept trying to "call home" and would flatten the battery after the car sat unused for several days in a row"

"The car has parasitic electrical drain"

"Battery kept discharging. Found to be a faulty digital communication module."

""The battery sold with the car is very inadequate for the amount of electronics that this car contains. I had to buy a much more powerful battery. But the battery still dies often because of interior lights that stay on, undetected.""

"Current drain while car is off has been an issue since the I purchased the car new. The battery has died many times After just sitting for a few days. Subaru paid for two battery replacements and finally had a fix for the battery drain in 2024 by modifying the fusebox. I am on a list to get a replacement module as a final solution for the problem."

"The DCM connects to Starlink and it kept draining the battery. There was a class action lawsuit and Subaru finally replaced it. It still cost me Replacement of 2 batteries."

"dead after hatch left open"

"Problem starting related to battery which Subaru replaced. Now it all works very well."

""The Subaru Starlink system is powered when the vehicle is off and it drains the battery. Subaru and the dealer replaced the battery, but did not fix the underlying issue causing it to be drained. I ended up fixing it myself by wiring the Starlink system fuse to the bus that isn't powered when the car is off.""

"know problem by subaru where 1 module continues to run after engine shutdown draining the battery"

"BATTERY HAD TO BE REPLACED"

"Had the phantom draw problem with the battery caused by(DEM?) constant searching of car communication system for 3g network. Car would be dead 1-4 days later if not driven. Bought new battery until notified by Subaru of recall to replace DEM? No problems since then."

""New battery died in driveway. Online research revealed only holds 70% charge and even though no Starlink subscription, car is searching for satellite 24/7. Dealer suggested putting on trickle charger daily""

"a sensor which monitors one of the safety features of the eyesight system was causing the battery to drain; after a few days of disuse the car would not start due to a dead battery"

""Alarm would go off when I touched the driver's side handle to open the car whether it was locked or not, strange beeping patterns when I unlocked the car via remote""

""THere was a problem with some of the electrical features, like the rear hatch didn't always open automatically and the hi beams didn't work right.""

"Control module defect was apparently draining battery requiring replacement. Finally replaced under extended warranty."

""A failed Data Communications Module (DCM) repeatedly drained the cars battery via parasitic drain. The DCM shorted out which caused a drain on the battery when it was powered off. Every 20 to 30 days the cars battery was dead. After three battery replacements (I only paid for one), Subaru replaced the DCM and (so far) the issue seems to be resolved.""

"The halo light went out and I had to replace the entire headlight assembly. Subaru charges an astronomical high price for this service."

"Running lights on one of the headlights died. Entire unit haad to be replaced."

"Battery in the keyfob would die in a year or less. Far too short a lifespan. Changing the battery is difficult."

""When the rear liftgate is left open the battery slowly discharges, due to a design failure coupled with an inadequate size battery""

""The liftgate opened on its own and remained open overnight, which discharged the battery.Subaru's "solution" was to give ne a new battery and disable the liftgate operating button on my key fob. Three years later, on a visit for an oil change, Subaru mechanics were able to restore the remote liftgate operating function.""

"car woukd not start, rear hatch would not open. battery was good"

"When the power rear hatch is kept open, the dashboard stays powered at 2.4 amps until the battery is dead. I measured this with a datalogger and DC clamp meter. Here are my images. https://photos.app.goo.gl/K8tdXo3c4Pn8joKbA Google search "subaru liftgate battery drain" for how big a problem this has been. I leave the gate open to access tools and loading and unloading. I have to push the electric catch closed to trick the car and shut down. If I forget, I may have to jump my car. Dealer once told me to "not leave it open" and "that is how it works"."

"Door wouldn't open from inside when clicked, window wouldn't open"

"Rear hatch frequently will not open using either remote or pressure pad. Has been evaluated twice without resolution."

"2 front windows do not close correctlty"

"There was some sort of defective module that drained the battery. Left me stranded more than once."

"Sensors on the liftgate went bad and had to be replaced. Liftgate would sometimes not work at all-even open manually"

"After only 3 years our touch screen clouded over and would not work. Subura replaced it but it was an inconvenience leaving the car at the dealership. A year later, we had to have a parasitic drain due to Starlink fixed because our battery would drain unless we drove the car regularly. We were stranded at airport after a trip the first time it happened."

""The modem for the Starlink system apparently became obsolete at the advent of 5G cellular service since cellular providers were shutting down old 2G towers to reclaim bandwidth. However, the modem kept seeking towers and put a drain on the battery that, when left for longer periods of un use while vacationing, eventually depleted the battery and caused premature failure. This may or may not have contributed to premature OEM battery failure however by the time I caught it, I was using a third-party battery so while Subaru disabled the modem under an extended warranty, I was fortunate that the third-party battery manufacturer covered the failed battery under their warranty. This is particularly aggravating, since I was not an active subscriber of Starlink.""

"Car would randomly beep the remote start runtime. Module was replaced and issue has gone away"

"keep failing"

"The tire pressure monitoring system (TPMS) started going on and off, but there was no problem with the tire pressure. I need to take the car to the dealer to have them check the system. Hope its not expensive!"

"Battery drain due to electric issue of trying to connect to onstar"

""When the tailgate or one of the doors is left open overnight, the battery completely drains. Regarding the tailgate, I had my Subaru dealer check several times whether there was a fix for this. The dealer was very helpful but concluded there was no fix for my particular Outback year. When the tailgate was left open overnight, the battery voltage fell to 6 volts. From online Outback forums, battery drainage problems appear to be not uncommon.""

""I had the battery replaced in 2023. This year it started to fail. I had three instances in six weeks where the battery was dead. At the third instance, I chose to replace the battery. I believe that this is because of a supposedly recallable issue That Subaru sent out. However, when I went to Subaru about it, they told me I have to pay $150 to test that part of the system if it turned out that that wasnt the problem. I chose not to do that. I however, did not buy my new battery from Subaru""

"ReAR hatch fails to open very often. It is motorized so forcing it open is a bad idea"

"The car battery did not keep a charge because it kept searching for a connection that I did not have and running down the battery when the car was not in use. The battery was replaced by Subaru at no cost to me."

"Battery drained due to starlink system. Was a recall issue."

""Garbled audio if I add my cell phone and play a book or music. Have stopped using this feature. Not an issue, obviously, with driving and safety, but annoying.""

"The radio sometimes didn't turn on. Then it started creating a massive rumbling bass noise that shook the driver's seat. The dealer had to take out the dash and the driver's seat in order to replace the responsible part. It was expensive and time-consuming."

"Early battery failure. First occurrence a about 3 years/25,000 miles and again at 6 yrs, 60,000 miles. battery appears to have drained overnight for no apparent reason, necessitating replacement of battery. There was a recall for an electrical system component that resulted in early battery failure, but dealer could not trace thes abattery failures to that recall problem"

"Radio - I cannot use it right now because it turns itself off and on and skips around to different radio stations. Subaru is going to replace it under warranty."

"Battery gets sapped when parked and turned off for more than one or two days. This summer I bought my 3rd battery."

""The device that communicates with Starlink malfunctioned, continually trying to connect even though that wasn't possible. As a result, it continuously drained my battery. When the problem was finally identified, a new device was installed and all is well.""

"Battery died because electronic power module tried to contact home internet signal to update system software every day while the car was in our garage for 8 months. Electronic power module and battery were replaced by Subaru at no charge to us. This occurred even when battery was connected to a trickle charger."

"Plug in a trickle charger every day. Dont trust the charging system which Subaru will not acknowledge. I believe there was a class action suit in Connecticut."

"The amplifier failed so no sound. It was under extended warranty so only paid my deductible"

""Something kept draining the battery; dealer kept saying nothing was wrong. Went through 3 batteries (last was Subaru battery), and still kept losing charge. This went on for about 9 months. Husband kept batter hooked up to charger so I wouldn't be stuck without a running vehicle. Finally talked to the service manager because I was ready to get rid of my car and buy a Toyota. I let the dealer keep my car for a week and they figured out it was a parasitic drain from the DCM module and one other module (I had previously asked them if that could be the problem, but they couldn't find anything draining the battery--at least not until they kept my car for a week). They replaced both modules and now I haven't had any problems since then.""
