THE PARKING BRAKE BUTTON CAN BE HIT ACCIDENTLY ALLOWING THE PARKING BRAKE TO RELEASE.
Consequence
UNINTENDED OPERATION OF THE PARKING BRAKE BUTTON CAN ALLOW THE BUS TO ROLL FREELY CAUSING A POTENTIAL FOR A VEHICLE ACCIDENT.
Remedy
DEALERS WILL INSTALL A PROTECTOR OVER THE PARKING BRAKE BUTTON IN ORDER TO PREVENT ACCIDENTAL RELEASE OF THE PARKING BRAKES.
Defect
THE STEERING ARM CAN DEVELOP CRACKS CAUSED BY REPETITIVE DRY-PARK-STEER MANEUVERS, PARTICULARLY DURING BRAKE APPLICATION. CONTINUED USE CAN CAUSE THE STEERING ARM TO BREAK.
Consequence
A BROKEN STEERING ARM CAUSES COMPLETE LOSS OF VEHICLE CONTROL WHICH CAN RESULT IN A POSSIBLE ACCIDENT.

DEALERS WILL REPLACE THE DEFECTIVE STEERING ARM WITH A NEW STEERING ARM.

Defect
THE SAFETY TAB USED TO RELEASE THE ROOF EMERGENCY EXIT MAY BREAK. IF THE TAB BREAKS, THE EMERGENCY EXIT CANNOT BE OPENED.

The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 4 recalls should be verified as completed.
