I lost power to my 2010 Mazda cx7 while going 60 mp downhill in a mountain pass. My car went from 60 mp to 40 mp in about 30 seconds. I immediately pulled over as black smoke poured out of my tail pipe and had the car towed. My mechanic said the turbo was blown, which cause the car's oil to completely burn up, causing damage to the timing chain and engine. All of the oil was gone in a matter of a few miles. The car had been up to date on all maintenance. A new turbo and engine was needed on a car that had 74,000 miles on it.
While driving on the turnpike my car started to make a whining noise then smoke came from tail pipes. After having it looked at the turbo charger has gone bad!.
