Example complaints
Engine: “I was driving into the highway and my vehicle just shut off. I was in the car with my children and I was scared that we were going to be rear ended. I had my mechanic look at the car and he advised me that the water pump leaked and the coolant leaked into the oil. I’m having another mechanic provide me with an estimate of how much the repair is going to cost. After the car shut off and I tried to turn it in again the batter, engine and oils light went off and I had the car towed to the local mechanic.”
NHTSA complaint #11425780, filed 2021-07, 67,384 milesOther or unknown: “I have a problem with getting in my car and finding spiders and spider webs. I have been bitten by them and so has my fianc. I got in the car yesterday and a web was coming from the air conditioning vent to the gear handle.”
NHTSA complaint #11328817, filed 2020-06, 9 milesBrakes: “We have 2015 Mazda CX-9 with 8400 miles that has a leak on the break master cylinder. Which the dealership was denying to be a leak because they saw an old dry debris on top of the fluid depot. But have it checked to an outside mechanic because we've been having a shimmy problem when braking for moths and they still can't figure as to what is wrong with our vehicle. All they are saying is they cannot duplicate the problem that I am saying. …”
NHTSA complaint #10851060, filed 2016-03, 8,400 milesTransmission and drivetrain: “We have a 2015 Mazda CX-9 Touring with All-Wheel Drive (AWD). The issue that has been happening is a flashing check engine light (CEL) indicator showing up in the gauge cluster. This issue originally started in October of 2023. I was on the highway doing at least 55 miles per hour (mph). Before the light actually came on, I had already felt the vehicle shaking, and also noticed the acceleration was sluggish. In the blink of an eye, the CEL came on and started flashing. After that point, the CEL stayed on. I was able to get to my destination safely. …”
