There are 2 owner-reported suspension complaints for the 2018 BMW 7 Seriesin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2018 BMW 740i. The contact stated when he was starting his vehicle a warning for "chassis" was illuminated. The contact stated that the vehicle was leaning. The contact stated that the driver side of the vehicle was raised from the road by about 4 inches and the passenger side of the vehicle was almost touching the road surface. The contact stated that turning the vehicle to the left or the right was difficult due to the lean of the vehicle. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed and was not repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline. The failure mileage was approximately 96,000.
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.
