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-pocke

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.
