Recall 10V646 affects 12 2011 Tmc Chateau Sport and Four Winds 5000 vehicles for a misplaced LP heat shield. Free dealer repair.
Tmc is recalling 12 2011 Chateau Sport and Four Winds 5000 motorhomes because a required heat shield next to the LP gas tank was not installed in the proper place. Without that shield, exhaust heat is not properly dissipated around the tank, which raises fire risk; the dealer repair will be free once available.

What's wrong?
The LP gas tank on the 2011 Tmc Chateau Sport and Four Winds 5000 stores propane for the motorhome's onboard appliances. A heat shield is supposed to sit next to that tank and block exhaust heat, so the tank area does not absorb heat from the vehicle's exhaust system.
On affected motorhomes, the required heat shield was not installed in the proper location. That leaves the LP gas tank area exposed to heat that should be deflected away. When exhaust heat is not properly dissipated around the tank, the area can overheat and create a fire risk.
There is no warning sign before failure. Because the problem is the missing or misplaced shield, an owner is unlikely to hear, smell, or feel a clear change before heat builds near the tank.

What happens at the repair
At the dealer, a Tmc technician relocates the heat shield to the proper position on the chassis next to the LP gas tank. That shield is meant to help protect the tank from exhaust heat. Because the remedy status is not listed in this record, schedule timing has to be confirmed with the dealer, but the dealer repair is covered by the recall once available. Parts and labor are free.
