Service bulletin RC000236SADealer

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

On certain Mercedes-Benz Sprinter vans, the MBUX multimedia system software might not meet specifications. Under very specific conditions, the MBUX multimedia system might not start and the display might remain black, or could reboot unintentionally after 50 seconds of initial startup. Accordingly, the rearview camera image might not be displayed or the display might be interrupted, which could increase a risk of a crash or injury. This affects the following Thor Motor Coach products: model year 2020 Citation, Siesta, & Synergy; 2020-2022 Delano & Tiburon; 2021-2022 Sanctuary & Tranquility motorhomes.
