Summary: Roof hatches may be propped open to allow for fresh air ventilation. The prop mechanism was designed to disengage when full opening of the hatch is required to exit. The release button that disengages the prop mechanism may require excessive force to release, which fails to conform to the requirements of federal motor vehicle safety standard no. 217, "bus window retention and release".
Remedy: Newly designed prop mechanisms will be installed. Parts will be supplied at no charge and labor will be reimbursed.

Has your Motor 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.

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 Motor Coach dealer can also check your VIN. Recall repairs are free.
