This Problem Across All Years
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.

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.

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

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.
