| Power Train problems |
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 can be replicated in all driving modes. Observation: when braking or even when coasting to a stop the vehicle will slow down rapidly, as if the brakes are being tapped hard (the brake pressure is constant and occurs even when not braking) for a brief second and then release causing a lurching motion. This lurching motion is enough to concern while driving as a possible loss of traction. It feels as if the car is engine braking. This issue puts the driver, passengers, and other vehicles at a safety risk. I have had passengers state that it gives them motion sickness. I have reported this to the dealer and they had the car twice. The second time was for a substantial amount of time. The dealer is on record stating that they can recreate it, observe it, but have not been able to fix it. They have reset the software on several systems including the transmission. There are no third party devices on the car, the car is stock, there are no warning lights. This has been the case since day one of having the car (brand new).
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.
