Service bulletin RC000220SADealer

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

MBAG has determined that on certain model year 2019-2020 Sprinter vehicles, the retaining washer on the bolt that connects the brake pedal to its bearing block could come loose. If the retaining washer were to come loose, over time it could detach from the bolt, and in the worst case and with ongoing use of the brake pedal, the bolt might separate from the bearing block on one side. If this were to occur, the brake lamp switch could become continuously activated even when the brake pedal is not pressed. If the brake lamps are continuously illuminated, it would not be possible for following traffic to determine the braking intention of the vehicle, which could increase the risk of a crash. This affects the following Thor Motor Coach products: model year 2020-2021 Citation, Compass, Daybreak, Delano, Four Winds, Freedom Elite, Gemini, Quantum, Siesta, Synergy, and Tiburon motorhomes.
