TIFFIN Complaints

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.

Cummins engine serial number 73927429 Isb6.7l Premature failed turbo actuator Known issue being ignored by Cummins.

This is related to recall #25V-481. A Mercedes Benz dealer (Mercedes Benz of Loveland) is refusing to complete the recall fix issued to my vehicle, even though I have the safety notice letter with my VIN. In conditions where the charge on the house batteries is low, the secondary alternator activates while the engine may be in a low idle state which can cause the engine to stall. The gas pedal can be pushed to the floor with no effect. This happened on the highway with the result being cars having to emergency avoid behind me.

All rear and side marker lights stop functioning without notice. The FCCC Motorhome Chassis rear PDMs is at fault, again (reference NHTSA #20V-404 with at least 2 notices). FCCC provided a work around for PDMs that took care of potential loss of brake and turn signal lights that stop functioning. Unfortunately the marker lights potential issues has not been addressed. Marker lights that do not function correctly increase the risk of a crash after sunset (at nights).

The Lippert/Shwintek slide systems this vehicle are inadequate. The bedroom slide hardware has been replaced in 2022 (under warranty) and is in need of replacement again. The Salon slide hardware has also been replaced one in 2023 and is showing signs of abnormal wear. Symptoms observed are failure to extend/retract, damaged rails, and slide pushing out while vehicle is in motion. The primary cause appears to be improper installation during the manufacturing process by Tiffin Motorhomes, Red Bay AL.

Alcoa outer dualy rim developed a circumferential crack. Alcoa returned under warranty. Now the opposite side wheel has failed. Alcoa part number 251802. Mfg date 081021 Made in USA

This vehicle has fuel fill on both sides. You have to open the other side in order to prevent a vapor lock on the fueling side. I have fueled this way numerous times without incident. I recently fueled the same way and fuel gushed out the opposite side without tripping the fuel nozzle cut off. This resulted on a significant amount of fuel dumping on the fuel bay.
