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.
