My BMW experienced repeated drivetrain, chassis, rollaway and other electronic malfunction warnings. After the warnings appeared, the vehicle behaved unpredictably. On multiple occasions, after I released the brake pedal, the vehicle unexpectedly increased speed rather than slowing. On other occasions, while traveling approximately 55 mph, it suddenly slowed to about 20 mph, and pressing the accelerator firmly did not restore speed. These incidents created a serious collision risk, including while transporting my four young children. The vehicle was taken to BMW of Bloomington for inspection and repair. The dealership contacted a BMW engineer and described the warning messages and abnormal…

Recently purchased used iX and successfully used the Parking Assistant Professional about a dozen times to back into my home garage using 5-point maneuver (driveway layout visible from aerial photo from address provided with report; drove in straight passed spot on garageâs left side looking in, other SUV parked in right spot, back into perpendicular spot in garage). After recording a new 3-point path, I tried it for the first time. During that attempt, the SUV suddenly reversed too fast to stop before crashing into another car in the garage. The vehicle initially followed the recorded path, then paused during first reverse because of an apparent obstruction (car approaching leaves on…

The car in front of me did not put brakes on or slow down and hit a car that was slowed to a stop in front of her. I was behind her and hit by brakes and tried to avoid the collision. My brake assist did not work; my car did not alert me and did not try to help me stop. I was told when i bought the car that it did indeed have these safety features which failed me. I was not sited in the accident even though i did end up hitting the car in front of me which was now attached to two cars in front of her. She was at fault and the car she hit had video footage to prove her fault.

While operating the vehicle, the steering system suddenly developed a fault with no prior warning. A "Changed Steering Effort" warning appeared on the dashboard, immediately followed by significant resistance in the steering wheel and violent mechanical shuddering/oscillation. This resulted in a sudden, dangerous difficulty in maneuvering the vehicle. Despite the 2024 BMW iX and related models (5/7 Series) having known internal steering gear manufacturing defects (referencing SIB 32 01 24 and Recall 24V-714), the dealership is attempting to deny warranty coverage. They are attributing the failure to a tear in the rack boot, despite no evidence of impact to the surrounding undercarriage. The…

Vehicle has displayed drivetrain and high-voltage-battery fault warnings on three separate occasions â December 2024, July 2025 (after replacement of a high-voltage-battery cell), and September 2025. Despite multiple service visits and nearly 90 days out of service, the same safety-related warnings have recurred. BMW NA and the servicing dealer (Chapman BMW Chandler, AZ) ultimately returned the vehicle to me in October 2025 without further repair, stating only a âcourtesy recheckâ was performed. I remain concerned that the vehicleâs high-voltage-battery system may have an unresolved defect that could affect safety or reliability. Please investigate whether similar cases exist for…
