“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 miles“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 miles“While driving my 2015 Mazda CX-9 on a very busy interstate, the check engine light appeared on the driver panel. I was traveling with my very young children, ages 4 and 20 months. Approximately 10 miles later, I started hearing a rattling sound under the hood. Shortly thereafter, my car stalled out as I entered my subdivision. My husband had to push the car to our driveway. I called aaa that same day and had the car towed to the dealership that services the vehicle. I was told that the water pump needed to be replaced and was quoted a price to fix the issue. …”
NHTSA complaint #11292498, filed 2020-01, 116,100 miles“I purchased the car new on september 18,2015. Having the car for 3 months I have been at the service department 3 times. I got home the first day and the belt was not registering and was making noise when I had it on. The last 2 times I continue to hear noise coming from the car. The noise is heard from underneath and it has to be driven for significant amount of minutes before the noise goes away. I recorded the noise on november 28,2015 and called the dealer very upset because its a problem that's not being addressed and fixed. …”
NHTSA complaint #10807974, filed 2015-12, 1,000 miles“I've had my Mazda for only 3 years. I was driving up the hill towards my house to park my car and it just quit working. It shut off and now it will not start. Now I'm stuck paying $400 a month for a car that doesn't even work. It's very disappointing. I think this car should be recalled.”
