Why it matters: Failure of the ecall system May result in emergency responders being dispatched to the wrong location, increasing the risk of injury following a crash.
The fix: Mbusa will notify owners, and the communication module software will be updated by a dealer, or through an over-the-air (ota) update, free of charge. The recall began March 12, 2021.
