  The contact owns a 2018 BMW 750I. The contact stated that while driving at various speeds, the engine overheated with the temperature gauge indicating that the engine was hot(H) with the check engine warning light illuminated. The vehicle was taken to an independent mechanic where the contact was informed that thermostat, thermostat sensor, and the water pump needed to be replaced. The contact stated that the vehicle was repaired; however, the failure worsened, and additional repairs were performed but the failure persisted. The contact was then informed by a mechanic that the engine oil cooler line was defective which had caused oil to leak into the engine coolant. The mechanic linked the failure to NHTSA Campaign Number: 17V377000 (Engine and Engine Cooling); however, the VIN was not included. The manufacturer was notified of the failure and informed the contact that the vehicle was not under recall. The manufacturer then referred the contact to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 87,000.
