Example complaints

“I started getting noise from the engine for last 6 months. But when the RPM is greater than 2000. The noise decreases, when I took to the dealer service, they mentioned that timing chain need to be replaced. Mazda knows about the issue and admits it but never performs a recall.”
NHTSA complaint #11270849, filed 2019-10, 104,000 miles“My daughter was driving the CX-7 on the highway and it caught on fire. There was a pop and then smoke and flames. My daughter moved to the left shoulder as soon as she heard the pop and the vehicle engulfed in flames. The vehicle was a total loss. At the time of the incident the vehicle was in great condition. The vehicle was at 94,000 miles. An oil change was completed recently as well as all regular maintenance.”
NHTSA complaint #11024871, filed 2017-09, 94,000 miles“I lost power to my 2010 Mazda cx7 while going 60 mp downhill in a mountain pass. My car went from 60 mp to 40 mp in about 30 seconds. I immediately pulled over as black smoke poured out of my tail pipe and had the car towed. My mechanic said the turbo was blown, which cause the car's oil to completely burn up, causing damage to the timing chain and engine. All of the oil was gone in a matter of a few miles. The car had been up to date on all maintenance. A new turbo and engine was needed on a car that had 74,000 miles on it.”
NHTSA complaint #11005194, filed 2017-07, 74,000 miles“Took car in for air bag recall (which was fixed). Dealer did a full circle inspection and found the timing chain needed replacement. We received a letter from Mazda january, 2012 stating they were extending the warranty to 7 yrs from the original warranty date or 70,000 miles whichever comes first for repairs to the timing chain. This letter leads me to believe they knew there were issues with the timing chain. Our car has 39,100 miles (obviously low for the age of the car). We were required to pay for the repair out of pocket because it was outside the warranty period. …”
NHTSA complaint #11166081, filed 2019-01, 39,100 miles“After I have come to a stop the check engine light and tcs/dsc indicator light illuminate. My car remains on but when I push on the gas throttle my car does not go anywhere. I have to turn off my car for a minute or so and then restart before I can drive. This had happen 4 times now (in a 2 month time frame). It usually happens when I am at a stop light and do not have a way to get off of the road. The check engine light stays on for a day or so and then goes away. Then it will happen again. …”
