“When the vehicle is decelerating and the transmission is in gear 2 the vehicle will lurch forward interfering/fighting with the normal operation of the brakes. This consistently happens when braking to a stop. The vehicle has 260 miles and I have driven it perhaps 4 - 5 times for a total of 30 miles. This is demo vehicle bought from a Porsche dealership and under full warranty.”
NHTSA complaint #11433244, filed 2021-09“While coming to a stop the vehicle lurches around 1200 rpms as the rpms are falling. The vehicle appears to already be in 1st gear when this happens.

This lurching motion is enough to concern while driving as a possible loss of traction. it feels as if the car is engine braking. …”
