1998 Monaco Coach Diplomat recalls, newest first

May 8, 2003NHTSA 03V166000

Equipment › Recreational vehicle/trailer

Summary: On certain motorhomes, fifth wheels and travel trailers equipped with norcold refrigerator cooling units model numbers 1200LR and 1200RIM, these refrigerators can experience low cycle fatigue failure which can lead to the liquid solution slowly leaking from the sealed, pressurized cooling unit through a small crack.
Consequence: If a leak occurs and the unit is continually operated, hydrogen gas may be expelled and can be ignited, resulting in a fire, possibly causing serious injury or death.
Remedy: Norcold will notify its customers and provide a replacement cooling unit free of charge. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact norcold service center at 1-800-667-3005 or monaco at 574-862-7211.

Fuel system, gasoline › Storage › Tank assembly › Mounting

Summary: Vehicle description: motor homes built on a roadmaster chassis. Inadequate bracing was used to secure the fuel tank. The brace could fail allowing one end of the fuel tank to loosen from its position and hang lower than the other end.
Consequence: The fuel tank could eventually separate from the vehicle and drop to the ground, increasing the risk of personal injury or a vehicle crash.
Remedy: Dealers will install an additional brace under the fuel tank.
