Example complaints

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

“Just driving down the road and my car stalled then lurched forward while I was in an intersection almost causing an accident. The repair shop stated a sensor had to be reprogrammed due to problems with the flywheel. I was told this problem will happen again as the flywheel in my vehicle is known to cause this problem. Something about flexing and cracking. It is my belief that this is a manufactures defect.”

“While accelerating onto the freeway, at approx. 55mph, in very heavy traffic with many big-rigs in the mix, the check engine light came on and the car suddenly lost power and began to shudder/miss out when accelerating. I had to quickly navigate over 3 lanes of fast moving traffic to avoid being rear-ended. I was able to drive slowly to a repair shop, but the engine would not rev above 2200 RPM. The service shop has tried 4 times to repair the car, each time replacing various sensors that were indicated by the engine computer. …”
