Show complaint excerpts

Was driving on a Saturday afternoon down a busy street when my car started sputtering and had very reduced power. I was able to eventually get to the side of the road and shut the car off.

NHTSA ODI report, 2021-03-05

Only 43,750 miles and the engine is being completely rebuilt. New cam adjusters, new timing chain tensioners, new timing chain guides... This shouldn't happen on a car with such few miles.

NHTSA ODI report, 2019-06-02

I was driving at highway speed when the engine suddenly started to shudder and lose power. The check engine light immediately started to flash and the engine stalled. I was stopped in a busy highway during rush hour.
