Technical Service Bulletin 511520 — 2021 FOREST RIVER SUNSEEKER

MBAG Recall 22V360 has determined that on certain Mercedes-Benz Sprinter vehicles, the communication module's SIM card might become disabled and prevent a connection with a mobile phone network. In this case, the manual as well as the automatic eCall function would not be available, which could preclude or delay the arrival of emergency responders. This might increase the risk of an injury following an emergency event. The supplier of the SIM card will update the SIM profile of the communication modules on the affected vehicles. This update is planned to be performed over-the-air with no workshop visit being required. If the over-the-air update cannot be successfully completed, the customer will be notified and advised to visit an authorized dealer to have the update performed.
