MAZDA Complaints

On a clear lane with the forward car 5 car lengths away with traffic flowing, the Automatic Emergency Braking (AEB) activated slowing my car down from 65mph to 30mph. I deactivated AEB on my exit and changed the AEB distance from “normal” to “near”.

Driver side door handle failed. Cannot enter or exit through driver side door. If something were to happen that we need to get out in an emergency situation we cannot exit through the driver side door. No damage occurred. Just stopped working

Steering "locks up" and the steering wheel is hard to turn back to center when making a left turn. When the vehicle was new and under warrant, I complained to Mazda-USA on 11/21/23 and took it to the dealer and the steering was better afterwards. I assumed they applied grease to something which was Mazda's fix for many other vehicle issues. Now the steering locking issue has returned again and the vehicle is no longer under warranty. I don't feel I should have to pay thousands of dollars to fix their manufacturing defect which came with the new vehicle.

premature failure of OEM Falkens on CX-90 PHEV at 20k miles, posing hydroplaning/skidding risk; Mazda denying full goodwil

I was driving it and randomly the AT and TC , and check engine light came on and the car went into limp mode, after doing some research it appears to happen to all 2009-2011 Mazda3's and it's a safety hazard. It's a safety hazard because of when it's stuck in limp mode sometimes if your at a light or something it'll start shifting and if you're not holding the brake completely down it will make the car lurch forward like 2-3 feet more if you don't react fast enough. This is a serious problem as it can cause a wreck. And you never know when it's going to happen there will be no symptoms it will just go into limp mode sometimes it'll rapidly go in and out and I'm sure that's causing damage to my transmission. Please make Mazda recall the TCM part and replace it. Thank you so much for taking the time to read my complaint/safety issue. Have a good day or night!!!

What component or system failed: The cylinder head failed due to cracking around the exhaust manifold, resulting in exhaust and coolant leakage. My independent mechanic and the Mazda dealer both confirmed this was the source of the burning smell and engine risk. The failed parts are currently in the possession of the Mazda dealership and available for inspection upon request. Safety risk: The failure created a strong burning rubber smell inside and outside the vehicle while driving. My mechanic advised this type of leak could lead to engine overheating, sudden power loss, or potential fire risk if not caught early. I frequently transport children in the vehicle, and the unexpected engine damage posed a significant safety concern. Has the problem been reproduced or confirmed: Yes. The issue was first diagnosed by an independent, certified mechanic and then confirmed by the Mazda dealership, who determined the cylinder head had to be replaced due to premature cracking and leakage. Has the vehicle/component been inspected: Yes. The vehicle has been fully inspected by an independent mechanic and the Mazda dealership service department. The dealership stated the failed cylinder head will be sent to Mazda for engineering review. Were there any warning lamps or symptoms before failure: There were no warning lights or error messages prior to the failure - which is alarming. The only initial symptom was a strong burning rubber smell that began shortly before the diagnosis. No overheating warnings appeared on the dash before the problem was confirmed. Additional context: The vehicle has 40,000 miles, has been fully maintained according to schedule, and is garage-kept. The Mazda service department acknowledged this failure is unusual and premature. Mazda has issued prior Technical Service Bulletins and warranty extensions for similar cylinder head/manifold cracking issues on the 2.5L turbo engine, but no program exists for the non-turbo engine, despite identical symptoms.

When I took the car into my ASE mechanic shop for a normal oil change and tire rotation, they performed a general overall car inspection. They noticed that the Driver Side Rear Subframe had rusted through completely, where the coil spring is located. The passenger side was rusted, but has not yet broke through. They stated that the subframe parts should not rust through like this. They also stated that it is dangerous to drive the car in this condition. I have not notified the manufacturer as of yet, but plan to do so. There were no warning lights, but the ride did seem to be rougher than normal. The attach photos contain 2 photos of the failed driver side rear subframe and 1 photo of the good, passenger side rear subframe.

LOW ENGINE OIL LEVEL light on about 1000 miles from last oil changed. Dealer fixed the Mazda recall code: P250F on July 30, 2025. Now is same issue of LOW ENGINE OIL LEVEL light on again on November 19, 2025.

At stop signs, in a row of 3 or 4 cars, on the 3rd or 4th stop, I apply the brake but it accelerates as i am braking, moving forward 8 or 10 feet. Over the course of 1800 miles, this has occurred 3 or 4 times, narrowly avoiding collisions.

2023 Mazda cx50 with 28k miles. This vehicle was purchased 3mths ago. The cx50 has locked me out 5 times & had a dead battery each time. Has been to dealership 3 times. No repairs made after dealership doing battery drain extensive testing. Cycle of this happening 3 times. I’ve been in a loaner more than my purchased vehicle. It is a safety concern leaving me locked at of my vehicle 5 times. Then when gaining access to vehicle with manual key. Vehicle has had dead battery 5 times all of this occurred over 3 months. With no repairs made from dealerships. It’s been to two different dealerships. Major safety concerns! The dealership has agreed to buyback the cx50. But it has taken a lot of phone calls with dealerships & Mazda corporate. Vehicle is still currently owned by me & awaiting buyback to occur this week. Not a safe vehicle!!! No warning lights no signs of any kind & battery continues to be dead. Battery changed twice by dealership. No other repairs done.
