-
Switch (exterior lighting)
These buses have a turn signal lever that will not operate consistently in the lane change mode if the lever is not moved to the position where resistance to movement is felt.
Remedy: Operators will be mailed information concerning the proper method of using turn signals. A decal will also be provided to be placed on the instrument panel of each bus.
-
Antilock/traction control/electronic limited slip (service brakes)
The wiring from the electronic control unit was connected to the wrong wheel sensor or to the wrong brake modulator valve. It is possible that either or both wiring may have occurred at either the front or rear axle or both axles.
Remedy: Dealers will inspect the ABS wiring and, if necessary, properly connect.
-
Hoses, lines/piping, and fittings (fuel system)
The fuel hose to the fuel filter is routed too close to the alternator belt causing the alternator belt to rub the fuel hose. This can cause a fuel leak.
Remedy: Dealers will strap the fuel hose to the chassis frame to insure a minimum of 2 1/2" clearance between the fuel hose and the alternator belt.
-
Hoses, lines/piping, and fittings (service brakes)
The hydraulic steel brake lines from the master cylinder to the frame fittings are experiencing vertical flexing which causes fatigue cracks at the frame end of the assembly, resulting in brake fluid leakage. This can occur in one or both of the steel brake lines. In either case, the brake warning light will come on and the low pressure…
Remedy: Navistar dealers will install a new, redesigned primary and secondary brake line from the master cylinder to the frame rail fittings.
-
Air suspension system (suspension)
The pressure relief valve was omitted in the air tank. The air tank is the reservoir for the air suspension and is not brake related. Without the pressure relief valve, there is no back-up system to limit air pressure in the air suspension system.
Remedy: Install a pressure relief valve in the air tank.
-
Linkages (vehicle speed control)
The bracket that supports and positions the hand throttle cable at the accelerator rod can be bent or misaligned during body assembly to the chassis.
Remedy: Replace the current throttle cable bracket with a new bracket; install at a different location.

Is the recall repair free?
