Chronological view of owner reports
Front differential complete fail. 56k miles. Replaced with new part, not an improved one but the same as factory at BMW dealership. My vehicle is 2021 x7 m50i. Reading other forums this is common if not standard on same models of this year. Very upset to have had to come out of pocket $9k to replace. Just outside of warranty. Was told will likely happen again in 50k miles. I wanted to keep this car like I have my other cars well into 170k miles. Looking to sell. Don’t understand how BMW doesn’t recall this.
The transfer case became damaged causing shuddering and loss of power while turning and accelerating. Once failed all power lost to rear wheels. My vehicle is available for inspection upon request and the problem has been confirmed by BMW dealership and replacement is required. Any loss of control of your vehicle is a safety hazard. This is a widely known issue and a recall has already been issued for years 2013-2016. The problem still exist in later models mine being a 2021.
