Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My son was driving my car to get food when the car lost control of steering and veered right towards the curb. His steering was straight but car was difficult to control. Thankfully he was only going 25 MPH. We took it to auto shop and was told engine cradle/subframe had rusted throughout. Very expensive repair. We also own a second 09 Mazda 6 that we now worry about and will get looked at.”
NHTSA complaint #11119417, filed 2018-08, 100,000 miles“I recently noticed that my dashboard has become cracked and very sticky . I do not know how this happened when I contacted Mazda to get it fixed I was told they can not replace that part . I don't know what to do I feel stuck I paid a lot of money for this car”
NHTSA complaint #11385454, filed 2020-12, 75,000 miles“This past week, while driving my vehicle to and from work on a public roadway, the steering wheel was off-center and the vehicle started to shift to the side of the road while vehicle was in motion while driving straight. I took it to an auto repair shop and they told me the sub frame is completely split in half and all corroded. The vehicle is undriveable right now. It's going to be very expensive to repair.”
NHTSA complaint #11119368, filed 2018-08, 117,000 miles“The front cradle assembly was rusted through and broke while I was on the highway. My mechanic said he had never seen anything like it on a car this new and it could have caused a very serious accident. A mechanic at the dealership where I bought the car said he has never had a problem like this with a Mazda 6.”
NHTSA complaint #10846298, filed 2016-03, 44,000 miles“My Mazda 6 started overheating during a heavy traffic day. Ever since, I noticed it would only start over heating only when the car is idle at a light, traffic, or parked for about 5 minutes and then slowly start creeping up. If I give it some RPM, the gauge comes back to normal reading. *additional info - heater only works when riding - I have to add a bit of coolant everyday - changed thermostat, fan control module and fans work well.”
