Porsche recalls 24,000 Panamera variants because of external coolant pump problems. February 1, 2023 — A Porsche Panamera recall involves more than 24,000 cars because humidity may enter the external coolant pumps for the climate control systems and cause electrical short circuits. Porsche says these cars are recalled because the short circuits could cause fires. According to Porsche, the fire risk comes from thermal damage to the external coolant pump. A Porsche Panamera driver may get warned of a short-circuit if the climate control system malfunctions. "Additionally, the subject vehicles are equipped with engine residual heat function (AUTO-REST), which can be activated when the engine is shut off and the vehicle is parked for a period of up to 20 minutes. In this instance, customers may not get a warning of the potential short circuit and thermal damage to the external pump."
