Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I own a 2006 Mazda speed6 with 96,600 miles, purchased december 2005. My speed6 has always had a turbocharger smoking problem. At one point, it looked like a mosquito spraying truck going down the road. But that issue seemed to abate, and appeared to be under control on its own. Now the car is burning a quart of oil every 300 miles. That is not acceptable, and after a yearlong attempt to watch the problem, to see if it could be controlled, I finally came to the conclusion, that it could not, and that the turbocharged had to be replaced. …”

NHTSA complaint #10565914, filed 2014-02, 96 miles

“For more than a year now we have complained to Mazda about the variable valve timing noise and the heavy white smoke from the leaking turbo. These complaints were done under the extended warranty. Mazda chose to ignore the issues and brush them off. The car needs repairs due to this matter. Mazda needs to be forced into a total recall to repair these many complaints.”

NHTSA complaint #10461839, filed 2012-06, 70,000 miles

“Driving the car on the turnpike and heard what sounded like a blowout. Immediately pulled car to the side of the road. Noticed the engine was not running. Attempted to restart, but made noise and would not start. Called husband, who arrived and said the engine had come apart. There were physical pieces of the engine block up to the size of a golf ball in the skid plate under the engine, as well as oil underneath the car and on the road. …”
