Summary: Mci is recalling 542 my 2000-2004 G4100 and G4500 motor coaches. Certain reworked tag axle arm assemblies had been identified with new cracks forming. Some of the tag axle arm assemblies that had previously been repaired during recalls 03V-411 or 06V458 may have been repaired with unidentified micro fractures and/or insufficient weld penetration.
Consequence: If the tag axle swing arm cracks and remains undetected, the cracks can spread and potentially result in a partial or total separation of the tag axle assembly from the coach, increasing the risk of a crash.
Remedy: Dealers will re-inspect and if cracks are identified or incorrect welds in the previously repaired areas, both right and left tag arm assemblies will be replaced. If no problems are identified, dealers will reinstall the existing tag axle arm assemblies with new hardware free of charge. Please note that this campaign supersedes mci's previous recalls (please see 03V411 and 06V458). The recall began on March 18, 2008. Owner may contact motor coach at 1-800-241-2947.

Has your MCI 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.

Check your VIN with NHTSA

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