EVWire brief: BMW is recalling, through sending out an Over-the-Air software update, 70,852 battery-electric vehicles built between March 2021 and January 2024 because drive-motor software can wrongly detect a “double-isolation” fault and order a high-voltage shutdown.
If that happens, propulsion is lost for about 15–20 seconds, although power steering and brakes remain active. Owners will receive a free software update, delivered as an over-the-air update or at dealers.
Context:
Affected BMW EV models: 35,414 i4, 25,280 iX, 5,484 i7 and 4,674 i5.
BMW logged 43 warranty claims worldwide, fewer than 0.1 % of the fleet. No crashes or injuries have been reported.
Dealer notifications began June 13; owner letters mail August 5 under NHTSA recall 25V-395.
The bug stems from code that can misread an isolation fault in certain production configurations. The remedy software eliminates the false trigger.
