2020 TIFFIN WAYFARER — Problems, Recalls & Safety Data

The RV currently is sitting at MB of Modesto where it can be inspected. The issue, when we attempted to rotate the rotatable front passenger seat, and an Airbag error was displayed on the dash and the vehicle was disabled, would not start. When we rotated the seat back we assumed it took pressure off of the wiring harness and the error disappeared and the vehicle started. We tried to rotate the seat back to its secure position but wires had become tangled under the seat and we could not secure the seat. We wanted to drive the RV to MB of Modesto but were concerned the airbag might deploy and disable the RV while we were driving. We decided to have the RV towed to Mercedes of Modesto. We discovered there were three separate recalls on this issue, MB Mfg #VS3DREHSIK, NHTSA Mfg. recall # 20V-322 and CA Bureau of Auto Repair # 20250701. Mercedes states that the recalls do not cover our specific chaise but the problem is exactly as described on the NHTSA recall. MB of Modesto inspected the RV and generated a Repair Order (RO) which is attached along with the NHTSA recall. The RO seems to imply that when Tiffin added the RV house they made changes under the seat that caused the problem thus the problem was not Mercedes. We contacted Tiffin and they said the problem was not theirs. Our Good Sam Extended would not cover it because it is a wiring harness issue. Seems like this is a MB and Tiffin wiring defect and the problem should be included in the recall.

Answers to NHTSA questions. Q. What component or system failed or malfunctioned, and is it available for inspection upon request? A. I don’t know if a system failed or malfunctioned, I only know how the system performed under the described conditions. Q. How was your safety or the safety of others put at risk? A. My safety and the safety of others were put at risk because the vehicle slammed on the brakes causing other drivers to respond to avoid a collision. Q. Has the problem been reproduced or confirmed by a dealer or independent service center? A. Yes/No, the selling dealer have said that they have heard about that happening but if it doesn’t happen while they are driving the vehicle, they can’t do anything about it. Q. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? A. No. Q. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? A. No. See attached file for detailed information. While driving my motor home with the Adaptive Cruise Control on, it will sometimes, unexpectedly, make a beep noise and then slam on the brakes for no known reason. When driving on a highway while using the Adaptive Cruise Control, if my vehicle drifts over the lane marking lines the vehicle makes a noise and slams on the brakes to move the vehicle back into my lane.
