2021 Winnebago Navion Problems

In December 2021, we experienced a failure of the RV Mercedes Sprinter to start. After calling a mobile technician out, and upon research of similar events, it was determined that the Electronic Ignition System had failed. We had the RV towed to Mercedes Service Center in Asheville, NC where the problem was confirmed. It appears that internal windshield condensation can drain into the dash and onto the EIS module resulting in corrosion and subsequent failure. We found a service bulletin (Reference XENTRY TIPS Topic # LI54.2-N-069524; attached) describing the issue and corrective actions. This bulletin is dated October 7, 2020. Mercedes Asheville repaired the damaged EIS module and installed the protective "boot" cover at our expense. Our Mercedes Sprinter had been taken our RV in for both Service A and Service B over the previous 2 years for routine scheduled maintenance. At neither maintenance event was the problem discussed or the corrective "boot" cover for the EIS offered. Our concern is that this is a known design defect that renders the Sprinter fully non-functional. The failure could occur at any point which could leave the drivers stranded in remote or potential high traffic areas. We would like to apply pressure to Mercedes to offer the corrective "boot" cover at all routine maintenance visits and also feel this defect warrants a safety recall to force action by the Manufacturer.

Our automatic electric awning has always had random electrical issues but two days ago, when retracting the awning, it didn't close completely and started jerking back and forth in between being almost closed and opening up 12-18". I resolved the problem by disconnecting power to the awning and then restarting it. Even though it appears to have closed properly, concerns about it opening randomly while driving have prompted me to secure it using tape and zip ties. There are numerous accounts online regarding random deployment of the awning. Because of the large size ("sail area") of the deployed awning, having it extend while traveling on a crowded highway at 65 mph is a great concern. There has been a recall issued (for improper installation and randomly opening) for the identical awning on the same vehicle, but for some reason the 2021 model year was excluded, even though the identical awning is installed in the same way on the 2022 and 2023 models.
