On my 2021 Porsche Cayenne Base, which is equipped with the 3.0L V6 EA839 engine, I brought the vehicle to the dealership for a recall service. During inspection, the dealership found a leaking water pump and quoted $8,500 for repairs. There were no visible signs of a coolant leak on the ground, indicating an internal seal failure. My independent technician confirmed that coolant is leaking internally into the vacuum system. This EA839 engine architecture is shared across multiple Volkswagen Group models, including Audi A6, A7, A8, Q7, and Q8, where this water pump internal leak is a known, widespread manufacturer defect that has already triggered class action lawsuits.

Problem with the hybrid system and the engine control system. Unit changed automatically and unexpectedly from battery power mode to engine power mode when on battery power mode only. This change is not supposed to happen. This failure happened when starting the unit, put on drive and starting to move forward. This failure caused the unit to charge forward with more power unexpectedly. Causing almost to collide. At the time of the failure “engine control system” warning and “e power not available” warning lid up. The unit has been for service for 10 times with the same warnings powering up. At this time the unit has been on service for almost four month.

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).
