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.
