NHTSA Complaint #11682608 — 2018 BMW X4

The water pump was found to have extreme corrosion after several other components on the car were damaged from the coolant leak into the electrical system. The car was suddenly losing power while driving and the DME was smoking, potentially causing an engine fire. So far the water pump, Digital Motor Electronics (DME) and throttle body were replaced over a 15 day period in service. The day the car was picked up, the chassis stabilization light came on and the dealership was receiving codes saying multiple additional electrical systems are now triggering the codes. The car was back at the dealer for service and now they are saying even more systems have been damaged by the leak. There is currently a recall on the water pump for this model and year, although this exact VIN is not included in the recall. Initial overheat warnings came on July 22, 2025 just prior to the car going in the shop although the dealer didn't see that the car was overheating. The fault codes were coming up as electrical. Only the dealer has inspected the car thus far. I content this car should have been included in the recall for the water pump as the description of the recall fits the exact damage to the water pump in my car.
