When braking to a stop, the car lunges forward even when foot is on the brake. This occurs at slower speeds around 5mph right before a dead stop.
When car downshifts from 2nd gear to 1st gear, it lunges / jerks forward, even as brakes are applied. Porsche mechanic and Porsche Cars North America both indicate nothing is wrong with the transmission. THIS IS A CONSTANT ISSUE. EVERYDAY FOR THE LAST TWO WEEKS. EVERY STOP.
The vehicle lurches forward dangerously when coming to a complete stop. The brakes seem to release as the vehicle lurches forward.
