  • miles
Strong unburnt fuel smell had just started at 6700 miles. Mazda Dealership stated that they would not be looking at my car and that gas smells are normal... After this encounter, I had 2 mechanics look at my car. Both had concluded that the smell predominantly comes from near the rear driver wheel, under the body, and that it is an extremely dangerous situation. I am a full time student and do not feel safe driving this car to class but I have no choice since Mazda is neglecting this issue. I also reported to the dealer that my brakes seem to be defective since they are causing excessive shaking when applied. Dealer informed me that they do not warranty the OEM brakes that came on my car, however Mazda Corporate informed me that they do. I do not feel safe driving this car knowing the car may combust and harm me and others on the road. The brakes also do not inspire confidence. A complaint has been filed with Mazda Corporate.
