Has your Monaco Coach been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Monaco Coach dealer can also check your VIN. Recall repairs are free.

October 10, 2003NHTSA 03V386000888 vehicles potentially affected

Equipment › Other › Labels

Summary
On certain motor homes, the federal identification tag on both 36' and 38' models was incorrect. The initial tag shows the PSI as 90 lbs. Front and 100 lbs. Rear. The correct PSI is 105 front and 115 rear. Also, the federal identification tag on certain units incorrectly states that the unit was built with a tag axle.
Consequence
Driving the motor home with under/over inflated tires can cause or contribute to premature tire failure, possibly resulting in a sudden blowout or other failure that could result in the loss of control of the motor home.
Remedy
Owners will be provided with a correct federal identification tag and installation instructions. Owner notification began October 24, 2003. Owners should contact monaco at 1-800-685-6545.

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.
