Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
If a customer were to rely on the Auto-P function as described in the Operator’s Manual, the possibility of a vehicle rollaway or unintended vehicle movement cannot be ruled out which could increase the risk of a crash.
Thor Motor Coach (TMC) is recalling certain 2020 Daybreak, Four Winds, Delano, Gemini, Quantum, Tiburon, Chateau Citation, Compass, Chateau, Siesta, Freedom Elite, and Synergy motorhomes built on Mercedes-Benz Sprinter chassis [platform 907 (VS30)] equipped with automatic transmissions.
The owner’s manual does not correctly specify the certain conditions under which the automatic parking function (Auto-P) operates.
