Suspension: “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.
