Recall Details on Electric BMW Models

BMW is recalling four electric vehicle models to address a critical issue with their drive motor software. The concern arises from the potential for these vehicles to suddenly lose power for up to 20 seconds, which poses a significant safety risk, especially during maneuvers such as overtaking.

The affected models include:
– 35,414 i4s built between 2022 and 2025
– 4,674 i5s from 2024 and 2025
– 5,484 i7s manufactured in 2024
– 25,280 iX SUVs produced from 2022 to 2024

Initially, BMW suspected that the drive units themselves were to blame. However, after multiple warranty claims between 2021 and 2022 indicated issues, the manufacturer extensively tested the drive motors, high-voltage batteries, and electronic control units. These investigations did not reveal any physical defects.

As the probe continued through 2023 and 2024, it became evident that the issue stemmed from a “true double-isolation condition” that prompted the high-voltage system to shut down. Ultimately, it was determined to be an erroneous signal indicating a fault when, in reality, it was only a single-isolation condition. This fail-safe shutdown was implemented to prevent possible electric shock or thermal risk.

Fortunately, even though the power loss could be alarming, BMW assures that drivers would still retain control of the vehicle, as power steering and brakes would continue to function normally. Reports indicate only 43 warranty claims related to this defect, amounting to less than 0.1% of the affected vehicles. Importantly, no accidents or injuries have been linked to this issue, highlighting its rarity.

The resolution for this problem involves a straightforward software update that can be executed at a dealership or over-the-air in compatible models. Notifications to dealers are set to begin on June 13, with owners receiving alerts starting August 5.

This recall reflects BMW’s commitment to safety, prioritizing customer well-being while ensuring that any identified issues are addressed promptly and effectively.
