Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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“when decelerating and car is in gear 2 it lurches the car forward while braking, basically fighting the attempt to slow the car down. I attribute this to aggressive downshifting, but is a safety issue because the operator then needs to compensate by pressing down on the brake pedal harder to stop the car. This has happened inconsistently when driving, but occurs more frequently than not.”
