BMW IX

I have backed up from my dirveway everyday for a month and the rear cross traffic nevered worked as advertised.

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 sudden electronic onset of the failure suggests an internal safety defect consistent with widespread reports on this model year, rather than environmental damage. There is significant online anecdotal evidence of this same issue occurring with 2023 and 2024 iX models, despite the above SIB only covering certain 2021 and 2022 models.

Tire size on BMW IX 2024 model 275/40 r22 sudden lost of pressure psi to 0. I saw a one inch rubber separation just below rim on the car. The tire might have hit a curb at extremely low speed going onto parking garage. no marking of side impact that would explain the opening separation just below rim All warning system after failure functioned correctly. The tire is suspect for this vehicle as the possible problem being on a heavy EV type car.

On October 17, 2025 at approximately 3:15 PM in the parking lot of a shopping mall at 2040 Lomita Blvd, Lomita, CA, our 2025 BMW iX M60 suddenly accelerated forward unintentionally while the driver was attempting to park. The vehicle made a loud “whirring” sound as if the motor engaged on its own, and it lurched forward rapidly without any acceleration input from the driver. The car traveled only about 2 feet before crashing into a wall in front of the parking space. All front and side airbags deployed. The driver (my father) suffered a chest fracture and hand laceration, and the passenger (my minor son) sustained severe bruises to the chest and shoulder from seat belt impact. The Driver (my father) was hospitalized for four days. The vehicle was towed to a body shop and is currently under insurance inspection for total loss. This appears to be a case of Sudden Unintended Acceleration (SUA) possibly related to the vehicle’s electronic drive control system. We request that NHTSA and BMW investigate this incident to determine if there is a safety defect in the 2025 BMW iX EV platform.

While driving my vehicle, the vehicle completely shut down and stopped. The seatbelt pulled me back tightly. A notification displayed on my dash Continue driving possible: High-Voltage system. Cont, driving possible: Drivetrain. You can continue driving. Have the problem checked by your service center. I did have to push the start control button to get the car started. The car behind was able to stop in time to avoid a rear end accident. This incident put myself and others at risk. Because the stretch of road i was driving thru was at a low speed, an accident was avoided. Thank God I wasn’t on a freeway. I was able to take the vehicle to a BMW service center. They did keep the vehicle for about a week. Waiting on a part. From our discussion with a service tech and invoice they replaced a Relay and said electric fan failed. There was no warnings prior to the incident. Received notification on my dashboard when the incident happened.

Vehicle has displayed drivetrain and high-voltage-battery fault warnings on three separate occasions — 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 “courtesy recheck” was performed. I remain concerned that the vehicle’s high-voltage-battery system may have an unresolved defect that could affect safety or reliability. Please investigate whether similar cases exist for 2024 BMW iX vehicles exhibiting repeated drivetrain/HV-battery warnings.

Issue 1- Car Starts to slowdown on its own when on self-drive mode on freeways – Has happened 3 X - service center has not be able to reproduce the error but many people on BMW forums has complained about the same in various driving conditions. Ours happened on a straight road with no car ahead of us but a car behind us which nearly caused an accident and a lot of anxiety . Our car went down from 70MPH to 40 and wouldn’t let me accelerate as well . Issue 2 - Front and Rear self-parking modes don’t work – Always have an error and goes in the wrong direction and doesn’t detect open spaces. For example it can’t decipher between grass and tarmac when the feature is being used in a driveway. Have recorded evidence and the BMW service station says the feature can’t be used on a driveway or garage- no documented evidence or information provided to us at the time of sale and till now . ( evidence of dealer notes also available) - Big safety issue as car goes on grass, hits garage walls, is reversing on side walks Issue 3 Reverse assisted parking doesn’t work flawlessly – even with the foot of the pedal it continues to speed and go fast - don’t think the service center even tried to duplicate this issue. All three are safety concerns for me and my family and is unacceptable. We have video recordings of the last two issues and screenshots are attached . The same have been shared with BMW but no one seems to care

The display was showing an error "drivetrain malfunction" and we could not drive the car. This looks like a common software problem with BMW IX
