# Service bulletin RC000210SADealer

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.

- Type: Service bulletin
- NHTSA id: 10197609
- Published by NHTSA: 2021\-06\-18
- Manufacturer's number: RC000210SADealer
- Manufacturer's date: 2021\-01\-18
- NHTSA component: STEERING

## NHTSA's summary

It has been determined that on certain Mercedes\-Benz Sprinter vehicles, the hydraulic power steering return line hoses might detach at their connection points under certain operating conditions, which could cause hydraulic fluid to leak, resulting in the loss of power steering assist. If the hydraulic power steering hose detaches, the driver will still have manual steering functionality, but increased steering effort will be needed, particularly at low speeds. Sudden loss of power steering assist as well as the loss of hydraulic steering fluid to the road surface may increase the risk of a crash. This affects the following Thor Motor Coach products: 2017\-2020 Chateau, Chateau Citation, Four Winds, Gemini, Quantum, Siesta, \& Synergy; 2018\-2019 Compass; 2018\-2020 Freedom Elite; 2021 Sanctuary \& Tranquility
