BMW issued a warranty extension covering air suspension struts for certain vehicles (8 years / 80,000 miles). I own a 2018 BMW 740i. I reported front suspension concerns to an authorized BMW dealership (United BMW, Alpharetta, GA) at 64,354 miles (8/16/23) and again at 77,582 miles(3/19/24. Service records document front suspension issues, including thrust-rod and suspension defects. During these service visits — which occurred within the warranty-extension period — the strut warranty extension was never disclosed or applied. The suspension defect progressed, and I later had to pay out-of-pocket for air suspension strut repairs totaling over $8,500, including OEM BMW front struts. BMW North America has denied reimbursement solely based on mileage, despite documented pre-80,000-mile service visits showing the defect was present and evaluated. This appears to be a failure to disclose an active warranty extension for a known suspension defect, resulting in unnecessary out-of-pocket repairs for a safety-related component.

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.

Apparently BMW models like mine have been having the coolant expansion tanks leaking between 60 and 70 thousand miles. This causes the coolant levels to drop and causes engine failures.
