What owners report

Owners of this model year most often describe front differential, transfer case, and drivetrain failures, and complaints are rising, with most filed in 2025 and 2026. Some drivetrain complaints describe shuddering that grows over time, while starter and oil pump failures are often described as sudden, with little warning. Starter motor failures, oil pump failures, and steering rack or front control arm problems also recur across the sample.

   What to check: Ask the dealer for the front differential and transfer case service history, including fluid changes and repair orders. On a test drive, check for shuddering or clunking at low speed while turning, and look for fluid dripping under the front of the vehicle.

   2 excerpts from owner complaints in NHTSA records

   “My X7’s front differential went bad at 50k miles. I paid over 100k for a vehicle of this caliber to have something like this fail and have to pay 8k with no help from BMWNA. I’ve been a loyal customer with bmw having owned over 5 bmw vehicles in the past. And for me to get treated like this is unacceptable. I hope we can have a law suit against bmw for this.”

   NHTSA complaint #11744077, filed 2026-06

   “Without warning the vehicle came to an abrupt stop while going about 25 mph. I got out and checked and noticed a liquid dripping from underneath the front area of the vehicle. Later determined it was the front transfer case. I really would hate to think what could have happened at higher speeds. Again, no warning at all.”

   Oil pump failure and sudden loss of oil pressure

   • 7 complaints (13%)
   • median 60,000 mi at 5.4 yrs old (1 states mileage, few)
   • filed 2025–2026

   Owners describe the oil pump failing, with oil pressure dropping or lost, sometimes with little or no warning before engine damage. Some reports name the B58TU engine and describe a plastic internal part that is said to fracture under repeated hot and cold cycles. Some describe warning messages about low oil or an oil pump leak, and some were towed to a shop before the pump was found to have failed. Most complaints do not list mileage; where listed, the figure is 60,000 miles, and the complaints were filed in 2025 and 2026.

   What to check: Ask the dealer whether the oil pump was checked for internal plastic failure and whether any oil pressure or low oil warnings are stored. During a test drive, watch the warning messages, and check the oil level on the dipstick before and after driving.

   “I am writing to formally report a potential safety-related defect involving BMW vehicles equipped with the B58TU engine, primarily affecting model years 2019 through 2021.

   Steering rack or front control arm problems

   • 6 complaints (11%)
   • median 42,000 mi at 3.4 yrs old (3 state mileage, few)
   • filed 2021–2026

   Owners report steering that feels unstable, heavy, or locked, sometimes with squeaking, clunking, or abnormal sounds from the front wheels. Dealers have diagnosed a faulty steering rack and front control arms, and some repairs were not done because of cost or because a recall did not list the vehicle's VIN. Other complaints describe a front control arm leaking hydraulic fluid, front thrust arm bushings failing again, or steering and braking that became less responsive at highway speed. Where mileage is listed, it ranges from 7,940 to 74,000 miles, and the complaints were filed between 2021 and 2026.

Buying note. Buyers considering this model year may want to ask for the differential and transfer case service history and confirm whether starter and steering recalls have been completed for the VIN. A pre-purchase inspection that checks oil pressure warning history and any drivetrain shudder or leak is a practical step.
