What owners report most

Verbatim excerpts from NHTSA complaints, by component

Power train

279 reports3 crashes
“Check engine light came on for the TCM. Car has had issues shifting (very rough shifting) and the manual shift option does not work. Was told the TCM had to be replaced. Attempt was made to replace it with a refurbished TCM but that couldn't be programmed to the car. Was then told I would have to buy a brand new one, which is very expensive, and that there was no guarantee that would fix the problem. Car can not be driven over 20mph without risking burning up the transmission. Car also jerks forward very hard when trying to gently accelerate.”
