2024 BMW Ix electrical problems

Filed Oct 23, 2026 · Acceleration, Electrical · MN

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 acceleration and deceleration. According to the dealership, the engineer directed its technicians to an existing BMW technical service bulletin concerning an electrical connector associated with the accelerator pedal wiring. The dealership replaced that connector and told me the repair was expected to resolve the drivetrain, chassis, rollaway and other warnings. BMW has not yet returned the vehicle. The dealership plans to keep it for several days and drive approximately 100 miles to check whether warnings or drivability problems recur. The repair's effectiveness is not yet confirmed. I do not know whether the replaced component is available for inspection or whether the exact cause of the speed changes has been established. I request that the federal safety agency investigate whether this connector or related wiring could affect accelerator signals or other vehicle systems, whether BMW has received similar reports, and whether the bulletin identifies a broader safety issue. The unexpected speed changes following multiple warnings posed a serious safety hazard even if the current repair ultimately resolves the symptoms.

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.

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.

BMW has issued an update to their software. There is a setting on the car where you press auto H and if you press the break, it will stop as if it’s parked now. This software update has a bug and nkw this feature turns off even though you have it set, so you think you’re parking and you press the brake and lift your foot which should put it into park and the car keeps moving and you hit other cars or people or anything. It is extremely dangerous.

I was driving on Single Pedal Drive on a freeway with the 2024 BMW IX, there was a slow down ahead of me. I removed my foot from the pedal and waited for car to slow down, but car didn't slow down enough. Then I slammed the brakes hard, but the brake didn't engage. In fact, brakes were pushed back against my foot. I was slamming the brakes as hard as I could, but i couldn't feel the brakes letting me me bottom out . This was a very traumatic experience. I have been able to reproduce it once again, but not always. But BMW dealership doesn't want to accept any problem. Thankfully, I had slowed down, otherwise, this is a very dangerous problem. Please investigate this. This has caused a big cost burden for me and also quite a traumatic experience.

On [XXX], while driving, the brakes on my vehicle unexpectedly seized, causing all four wheels to catch fire. This incident resulted in significant damage, including the burning of the brake lines. The vehicle was promptly towed to Wide World BMW in Spring Valley, NY, for repairs, as it is covered under the bumper-to-bumper warranty. Following the incident, I was informed that a team from BMW North America would inspect the vehicle due to the severity of the malfunction. I have since been advised that BMW North America is denying liability, claiming that third-party work may have been performed on the brake system. However, both Wide World BMW and I categorically refute this assertion. All maintenance on my vehicle has been exclusively performed by authorized BMW service centers, and there is no evidence to suggest that any third-party work was done. The damage being attributed to third-party work is, in reality, a direct result of the fire caused by the brake system malfunction. Wide World BMW has reviewed the case and agrees that BMW North America should assume responsibility for addressing this issue.

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.

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?

I put my car to charge at a manufacturer recommended charging station. I went for a short walk and when I came back, the fire department had arrived. They informed me that the car had caught fire and that it was put out by a good Samaritan using an extinguisher. The car was not drivable and there was visible fire damage
