We expect the 2025 3 will be more reliable than the average new car. This prediction is based on data from 2023 and 2024 models and the Mazda brand score.
The Reliability score is based on our latest subscriber survey of 2019 Mazda 3 owners. The owner comments describe problems respondents experienced with this vehicle.

"Consistent clunking noise from the front. Two independent shops misdiagnosed as control arms. Finally took to dealer after discovering a Technical Service Bulletin regarding the problem. It has occurred on several models of Mazda over several years. Dealer wasnt aware until I showed them the TSB. The car had less than 35,000 miles on it but was out of warranty. They replaced upper strut mounting hardware and right front strut. I had them replace left strut as well. Paid $200 for diagnostic and $879 for repair."

"I started having problems around 31,000 miles with smelling burning oil from under my hood, and smoke would drift up on my windshield. The dealer said it was a bad gasket, cleaned the area, and supposedly fixed it. Smoke and smell persisted. I took it back to the dealer and was told the block had an internal crack, a manufactured flaw, and the motor needed to be replaced. I was told it would be about 3 months. I received my car back in less than a month and question if it was really replaced or just patched as, on occasion, I have the burning oil smell."
Anonymous, FL (2019 Mazda 3 Preferred 2.5-L 4 Cyl)Premature pad/rotor wear, pulsation or vibration, antilock system, parking brake, master cylinder, calipers, squeaking, brake failure, regenerative braking.
"Brakes began squeaking at about 18000 miles. I requested the Mazda dealership to review and was told that brakes were fine. At about 20000 miles brake squeaking began getting more frequent - mostly at slow speed stops. I recently took it to a mechanic and had to replace both the pads and rotors on the front brakes. I have never had to replace the brake pads/rotors on any other vehicles that I have owned under 40,000 miles. This seems premature and should have been fixed when requested previously."

"At around 38,000 miles and 3.5 years of ownership, the leather on the passenger seat, which is rarely sat in, started to peal and flake. The dealer said I cleaned the seat with a product that caused it. However, I had never cleaned the seat because no one routinely sits in my car. I'm single. After complaining that was not the case, they tried to fix it with liquid vinyl and completely messed it up. The dealer was forced to replace the leather seat cover and decided to apply it to my extended warranty. All my issues seem to be with dealers."

"I haave had 3 batteries in the past year. The car doesn't seem to turn off completely. It seems that the accessories are still on but draining the battery. The dealership now wants to disassemble the rear of the car because someone rear ended me last year. But the problem is that the car sporadically won't completely turn off."
