2021 BMW X7 Powertrain & Transmission Problems

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.

very known issue of catastrophic failure to the oil pump, made in Italy with plastic component, used in my vehicle. The part has been updated to metal components on bmw side without any knowledge to the customers with same part number. Faulty xdrive tranfer case, wheel jerks on low speed turning. Currently in class action lawsuit.

The water pump pulley "exploded", causing the accessory belt to fall off which drives the alternator. The pulley "shrapnel" was thrown into the cooling system and damaging the hoses causing immediate loss of coolant. The loss of electrical power due to the alternator being inoperable and the loss of cooling could have caused the vehicle to malfunction in a dangerous manner. Fortunately, the vehicle displayed an error message and was towed to the dealer without further incident.

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.
