BMW is issuing a recall for four electric models due to an issue with their drive motor software. The affected vehicles, which include the i4, i5, i7, and iX SUVs manufactured between 2022 and 2024, can experience a loss of power for up to 20 seconds. This sudden loss of power can be quite alarming, especially if it happens while overtaking another vehicle.
Initially, BMW believed the issue was related to the drive units themselves, but after further investigation, it was determined to be a software issue. The company received a small number of warranty claims related to the problem, but it was challenging to identify the root cause. After extensive testing of the drive motor, high-voltage battery, and electronic control units, BMW concluded that there was nothing physically wrong with the vehicles.
The recall notice filed with the National Highway Traffic Administration (NHTSA) explains that the problem is a “true double-isolation condition,” which triggers a high-voltage system shutdown as a safety measure. While losing power unexpectedly can be dangerous, BMW assures that the power steering and brakes will continue to function as designed, allowing drivers to maintain control of the vehicle.
Fortunately, only a small percentage of the affected vehicles have experienced this issue, with less than 0.1% of potentially affected cars reporting the problem. No accidents or injuries have been attributed to this defect. The remedy for the issue is a simple software update, which can be done at a dealership or over the air for vehicles that support this feature.
Dealer notifications for the recall will begin on June 13, with owners being notified starting August 5. This proactive approach by BMW demonstrates their commitment to ensuring the safety and reliability of their electric vehicles. By addressing this issue promptly, BMW is taking the necessary steps to keep drivers safe on the road.
