Consumer Description

Vehicle would start and then shutdown. It would display the battery malfunction error. You would need to reset the vehicle with the key in order to activate/start the vehicle again. Dealer said they need to replace the MUC but Mercedes told the dealer to try a software update before. The vehicle is still not running the more recent software RL_NTG7_E316.505_22092AC3. Other vehicles are running E330. I don’t believe the dealer updated my software and this issue could happen and caused the vehicle to become disabled somewhere which would case an issue.
