2021 BMW X7 Engine Problems

Front differential needing completely replaced at 44,000 miles. Might need a transfer case replacement as well. Original quote of $8,300 and if the transfer case is needing replaced, another $8,000-$10,000 job. I have done research online that a lot of other people with X7's are having this issue. Autobahn BMW in Fort Worth, Texas confirmed the issue and that it needs complete replacement done. There were no warnings, no lights on the dash, and nothing that would indicate there was an issue until leaking starting and I could smell the oil burning.

Infotainment stopped working, no backup cam no safety features working

two fan blades came off and punctured my radiator. I replaced the radiator/fan for 4300 and when I picked it up, it said the power was limited and to get it to a BMW dealership right away and when I took it to BMW, they told me the engine was shot and cylinder four was completely destroyed. Then both through BMW corporate and the dealership that I bought the car at new in 2022 I was told there was nothing that they would do at all. In fact I was told it would cost $46,500 plus tax to replace the engine. The car is only worth 40 and I owe 29 I have been without a car for many months and I don’t know what to do with this card is essentially become a paperweight. I bought it brand new at arrowhead BMW for almost $115,000 with 3000 miles on...

Car had an error message "drivetrain malfunction" car was drivable. Car has 87000 purchased in 2021. Car needs a new engine. Other Car owners having similar issues with the drivetrain malfunction

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.

2 Issues: 1) The water/coolant pump leaks and fails, leading to overheating. BMW says the following Service Bulletin does not apply: SIB 11 05 21 SERVICE ACTION: REPLACE THE MECHANICAL COOLANT PUMP I'm not really sure why or how it doesn't apply but it should. 2) The front passenger seatbelt has failed, in that it does not retract into its housing.

I was driving a car with family and all of a sudden we all started smelling a burning smell but we thought it must be from outside. However, in just few seconds the vents started throwing vapors so I stopped the car hoping it may stop if some minor damage. However, the hood started throwing oranges color fumes and by the time we all left the vehicle the entire front hood/engine area started burning. There were no indications of any faults in the car. This was the most shocking incident we had to face with my family where there were two kids of 4 and 9 along with my wife and her parents who are senior citizens.
