2021 BMW X7 Steering Problems

The vehicle experiences a recurring drivetrain shuddering or slipping sensation at low speeds, especially when accelerating from a stop or while cornering. The issue originates from the transfer case, which has been identified as the malfunctioning component. The transfer case was previously serviced according to the manufacturer's official technical bulletin, but the problem returned after the prescribed post-repair evaluation period. The condition compromises vehicle stability and creates a potential safety risk, particularly when merging into traffic, turning at intersections, or navigating tight spaces — where unexpected hesitation or loss of traction can lead to a collision. The issue has been confirmed by authorized dealership technicians, and acknowledged by service personnel as a commonly recurring defect in this vehicle model. The manufacturer has not issued a recall but has documented the issue in an official service bulletin. The component is still installed in the vehicle and available for inspection upon request. There were no dashboard warning lights or fault codes present prior to or during the symptoms. The only observable indication is the physical sensation of shuddering/slipping, which persists intermittently and without system alerts

Wheel/Tire makes shudders during a turn at low acceleration or going up a hill leading to uncontrolled acceleration. I have brought the car in for inspection and service and the issue could not be replicated by the techs, however the problem occurs with daily driving. An online search shows that this is a very common problem with the transfer case.

2019-2022 BMW X7 Xdrive have a major issue with the transfer box which controls the adaptive steering at all front wheels. At low speeds or at driveline when accelerating in forward or reverse while turning the steering wheel the vehicle shudders or jerks causing the skipping like feeling in traction. This is a common issue which is reported by many and is now happening to my vehicle. BMW has not issued a recall, rather a recommended repair to change the oil on the transfer case and drive the vehicle for 125miles hoping the issue will go away. In most cases the issue does not go away and the transfer box needs to be replaced. The interesting thing is BMW is charging customers 500.00 for the transfer box oil change when its a known issue and hopefully if you are still under warranty will replace the transfer box if the issue persists at not cost. If not under warranty the cost of the part alone is 4350.00 for the transfer box, not including labor. This is a very major driver safety concern as it pertains to steering and handling of the vehicle. In my opinion, BMW should not be charging customers under warranty for the transfer box oil change in hopes of it resolving the issue. There should be a recall for the transfer box entirely as this is an issue on all BMW X7s. There is no warning lights regarding the transfer box issue. The issue is continues at all times while driving at low speeds and turning at the same time. This can cause someone to lose control of the vehicle in a turn and get into an accident. Please refer to BMW recommended repair SIB 27 02 20, link provided below. [XXX] If this is a known issue, and NHTSA is aware of the issue then why isnt there a recall to replace the transfer box entirely if the issue is confirmed by the dealer. Why put a band aid by replacing the oil on the transfer box when it will eventually return? If the vehicle is not under warranty, why should customer pay.

While merging onto the highway the car violently jerked itself into the left lane without warning, nearly causing me to collide with another car. Error messages about "driver assistance" appeared. All screens then went black and the car rebooted. It pulled away from the direction I was driving several more times on my way home, but less severely. 3 weeks earlier multiple systems failed and power steering went out. That time the car was pulling me in the opposite direction I was steering. Was told it was a software issue that was fixed. Then this happened 3 weeks later.

The transfer case in my BMW X7 began making grinding, jerking, shuttering around 65,000 miles. The dealer failed to diagnose the issue at that time when I brought it in at 71,000. (approximately $9,000–$10,000). Transfer cases "should be" designed to last well over 150,000miles. Maybe my car was a lemon but it seems to be a common theme/legal suite for BMW X7 owner.s This issue connitued causes sudden loss of power delivery, shuddering, and unpredictable handling—especially during acceleration or turning—which can increase the risk of an accident. Many BMW X7 owners have reported similar premature transfer case failures online, suggesting a widespread defect that may affect vehicle safety. BMW should investigate these failures and take accountability for transfer case defects that appear to occur prematurely and often shortly after warranty expiration. Consumer forums (like Bimmerpost and CarComplaints.com) show multiple reports of X7 transfer cases failing between 50K–90K miles.
