- Affected autos can lose energy for as much as 20 seconds, which sounds very harmful.
- Solely 0.1% of the doubtless affected vehicles reported the issue, which may be mounted by way of a software program replace.
Instantly dropping energy and coasting for as much as 20 seconds sounds fairly scary, particularly should you’re halfway by overtaking one other car.
That’s the potential situation confronted by 70,852 electrical BMWs manufactured between 2022 and 2024. The corporate has issued a recall for what it describes as defective drive motor software program. The affected fashions are 35,414 i4s constructed between 2022 and 2025, 4,674 i5s from 2024 and 2025, 5,484 i7s in-built 2024 and the 25,280 iX SUVs manufactured from 2022 by 2024.
BMW had initially attributed it to points with the drive items themselves, not the software program that controls them, but it surely was so uncommon that it couldn’t discover what the issue was.

Nevertheless, after extensively checking the motor, high-voltage battery and digital management items, BMW didn’t discover the supply of the difficulty.
As a result of the variety of stories and guarantee claims was very low, “it was not doable to affiliate every particular declare with the provider manufacturing situation.” It then continued the investigation into the difficulty by 2023 and 2024, when it grew to become clear that there wasn’t something bodily flawed with the autos.
In response to the recall discover filed with the Nationwide Freeway Visitors Administration (NHTSA), BMW explains that it was finally in a position to pinpoint the issue as “a real double-isolation situation, which warranted a high-voltage system shutdown,” though it was “in actual fact, solely a single-isolation situation.
In such circumstances, and as a fail-safe measure, the high-voltage system was shut down with the intention to stop any chance of electrical shock and/or thermal threat.”
Fortunately, though unexpectedly dropping energy may be very harmful, BMW says that when this energy loss happens, the ability steering and brakes proceed to perform as designed, permitting you to keep up management of the automotive.
The producer stories that 43 guarantee claims had been filed on account of this defect, accounting for lower than 0.1% of all doubtlessly affected autos, indicating that it was a really uncommon incidence. No accidents or accidents had been formally linked to this defect.
