Open the full vehicle complaint log (all categories)While driving in hybrid mode while both the gasoline and electric motor are running or shifting back and forth, occasionally the electric motor will come on with a sharp, sometimes loud, metallic “bang”. The sound and feel appears to be coming from the rear. The last two times it happened, the car lunged forward on its own without additional pressure on the accelerator, and once over the past week it lunged forward near an intersection when lifting off the accelerator pedal and engaging the brake. The lunge almost caused me to rear end the car in front of me which I was not very close to. This occurs about once every 50 miles travelled or once per day and at various speeds. To date it has not generated a CEL or any other type of warning.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
