Consumer Description

There is a pause upon acceleration from a stop (unresponsive). Then the vehicle will lunge forward and make a loud noise. For both driver and passengers, it can be quite startling and feels as though the car has been hit from behind. This started happening in the fall of 2021, when the car was about two years old with about 18,000 miles. It has happened about a dozen times in the six months since first noticed. It seems that this may be a software issue related to the hybrid system - a lag in triggering which motor to use for acceleration.
