2024 BMW iX Powertrain & Transmission Problems

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.

Drove the car and parked it. Went into the store and got back into the car. Turned the car on and it had an emergency light saying a drive train malfunction had occurred and that the car could not drive and had to be towed to the dealer for repair. Turned on and off the car. It still had the malfunction. Had the car towed to the BMW dealer. They tested it and came up with 7 codes of malfunction: charging unit, supply voltage, acceleration, drive function, ethernet and transmitter unit, battery below storability, electric a/c compressor. They reset the car and the codes went off. BMW North America then told the Santa Monica BMW dealer to test drive the car to see if they could replicate the error. They could not. Without inquiring why the car had stopped functioning, and without repairing anything, they returned the car. They said that this could happen again while I was driving and at any time but BMW did not want to figure out what was wrong until the next catastrophic failure occurred. There are numerous stories of drivetrain malfunctions on reddit. This is an electric car, it is terrifying that the whole thing could turn off at any time. In addition, the dealer says that they don't even know what the codes mean and that they have to ask BMW north America to tell them what to do once they send in the codes! Shouldn't a dealer be able to see what the failures are and have some authority to troubleshoot? It seems like BMW is withholding information from the public and the dealer by working in this manner with electric cars. In addition, why would anyone feel safe driving an electric car under these circumstances?

On 9/6/2023 I arrived home at [XXX] around 3:30 pm. I stopped the car and put the car in "Park". Immediately car moved with full force like a rocket and hit the garage wall head on. Car got stalled, while this happened I still had my seat belt on. I was able to reverse the car about 5 feet and put back in park but I was not able to shut off the car engine manually. I have been using the wallet key on my apple phone. That also failed to stop the engine of the car. Then I went inside the house and brought the physical key and it was able to shut the engine off.
