“The turbo made a loud whining noise when the accelerator was pushed and you could not accelerate. Alot of white smoke was flowing from the exhaust. We immediately pulled over on our way home from out of town and called aaa to tow the car back to the service dealer in parkersburg wv. The vehicle only has approx. 19,000 miles on it with service records showing proper oil changes. The vehicle is under warranty and Mazda sounds like they don't want to cover this problem.”
NHTSA complaint #10449713, filed 2012-02, 18,469 miles“I was driving my Mazda when it started making this odd winding sound. At first it was not too loud but when I tried to speed up to get on the interstate, the sound got extremely loud. I brought it back home but barely made it up the hill to our street. I had the gas pedal to the floor but it had no power. I called road side assistance and they picked up my car promptly. When the dealership called me back, they reported that the engine had gunk in it. My husband changed the oil in the car but we never saved receipts for the oil, so we have no proof. I bought this car brand new in 2010. …”
