Toyota Prius

"Not a major problem, but when i lock the door remotely (via key fob or button on drivers door) the interior lever doesnt always move to the locked position."

"Sometime in past year, the main lock button (on door of drivers side) has been faulty."

"The undercarriage of the 2017 Prius is so low that slowly going over a speed bump caused a piece of the undercarriage to either break or to become detached at a connector and then drag on the ground. Our car service center simply cut the broken piece off. The low clearance of the car is one of my original and continued criticisms I have about it."

"When it rains or during a car wash, water gets into the trunk and also the back seat floor gets wet sometimes."

"Noises often under the dashboard"

"I drove it home with a rattle under the dashboard. The dealer said, "No problem. We have three years to fix it under warranty." Three separate Toyota dealership repair departments have NOT been able to fix it. It rattles on back roads and we love to drive back roads. I admit that it is intermittent and therefore harder to hear and fix, but it doesn't stop it from being maddening when it happens. I had the issued bumped up to Toyota's Southeast Regional Office, but the local dealerships kept giving me the round around, so I stopped wasting my time contacting them. It happens less frequently, but it still happens."

"Unlike normal brake wear, my brakes rusted because when I drive, I usually end up using regenerative braking. My brakes sorted rusted themselves on, reducing my mileage and sounding bad. Because I knew I had some sort of brake issue, I was anxious to get it fixed. The dealer said the earliest appt was 3 weeks, so I got someone else to fix it. I don't remember whether my front brakes went first or my rear, but the same thing happened with the other brakes a year or two earlier."

"Rotors and calipers completely rusted through when we werent driving much in the 2020 pandemic and required full replacement"

"Were found to need replacing at annual inspection, I did not note a problem while driving."

"blew only very hot air. Not a refringent leak"

"Coolant leak caused overheating (no temperature gauge - warning light came on for a few seconds, off, on again). Stopped within 3 miles. Shop diagnosed bad thermostat, replaced it. Following week it was leaking coolant again. I did some research online, Prius owners suggested heat exchanger or water pump failure. Took it back to shop asking to check those things. Diagnosed heat exchanger failure and did a bypass to avoid coolant leakage. Will need to replace heat exchanger unit for $1200."

"Put in stop leak"

"It was triggered by a loose gas cap"

"In my opinion, the factory based Toyota Entune system is worthless. I would drive for five minutes and then the system went blank altogether. I restarted the vehicle several times to no avail. I ended up replacing the head unit altogether with a new one that included Android Auto. I have had no problems since. However, the radio takes 10 to 15 seconds after ignition before it becomes active."

"Cylinder 3 coil pack failure causing engine misfire. Replacement of coil pack did not fix issue. Took to shop and they determined it was an issue with the new coil pack and new spark plugs, but both were compatible with the vehicle."
