SAFETY RECALLS

The following are safety recalls issued by the National Highway Traffic Safety Administration:

Paccar is recalling certain TRP branded aluminum wheels sold for resale in the aftermarket with the following part numbers: AW2258B, AW2258M, AW2458B or AW2458M. The rim markings on these wheels were etched to a depth less than the minimum requirements. Thus, these wheels fail to conform to the rim marking requirements of Federal Motor Vehicle Safety Standard No. 120, “Tire Selection and Rims for Motor Vehicles Other Than Passenger Cars.” Without proper rim markings, owners may not be able to identify affected wheels in the event of a wheel recall. Defective or noncompliant wheels that are not remedied are at an increased risk of performance failure, and thereby increase the risk of a crash or other safety hazard to motorists.

Cummins is recalling certain model ISB6.7 diesel engines manufactured from Feb.16, 2010, through May 4, 2012, equipped with fan pulley Part Number 3914462 and installed on certain Thomas Built Buses, Inc. school buses. The subject fan pulley is part of the accessory drive system on the front of the engine. This system is used to drive such components as the refrigerant compressors, the radiator fan and the engine water pump. The web of the pulley can fatigue over time, causing the pulley to fail. If this occurs, the fan belt may lose engagement of the water pump, allowing the cooling system to overheat. This may result in exceeding temperature limits, potentially disabling the school bus. If the school bus is occupied when it becomes disabled, the occupants would need to exit the vehicle and be transferred to another vehicle, putting them at risk of injury.

Hayes Lemmerz International Commercial Highway, Inc. is recalling certain commercial steel wheels, models 90262, 90541 and 10073 with date codes ending in 030512, 030612, 030712, 030812 and 030912. These wheels were sold as aftermarket/replacement equipment or installed as original equipment in various commercial highway tractors, trucks and bus applications. Due to an inadequate weld between the wheel disc and rim, the disc can separate from the rim. Separation of the rim and tire from the vehicle can result in a loss of control and a vehicle crash.

Mitsubishi Fuso Truck of America is recalling certain model year 2012-2013 FEC52, FEC72, FEC92, and FGB72 trucks; manufactured from April 8, 2011, through Oct. 16, 2012. The parking brake cable nut may have been insufficiently tightened during assembly. As a result, the parking brake cable could loosen with each operation of the parking brake. Continued use of the parking brake could result in the inability for it to hold the vehicle stationary. This may lead to a truck rollaway increasing the risk of pedestrian injury or a vehicle crash.

Daimler Trucks North America is recalling certain model year 2010-2013 Freightliner brand XB and XC custom chassis manufactured Jan. 1, 2010, through Sept. 20, 2012. The chassis are equipped with diode jumpers that may come loose in their connectors resulting in an open circuit. Two circuits are affected: the one that disengages the cruise control with brake pedal use, and the one that illuminates the brake lights with brake pedal use. Failure of the cruise control to disengage when the brakes are applied may increase the risk of a vehicle crash. Without the brake lights illuminating when the brakes are applied, the driver’s intent is not communicated, increasing the risk of a crash.

Navistar is recalling certain model year 2012-2013 International brand 9900, LoneStar, PayStar, ProStar, TranStar, and WorkStar commercial trucks, manufactured from Aug. 1, 2011, through July 31, 2012, and equipped with front brake linings listed as feature codes 0504501 or 0504504. The brake S-Cam tube bracket assemblies on the steer axles may fracture. Brake assembly fractures may result in an inoperative brake on the affected wheel. This will cause the vehicle to pull to one side unexpectedly during breaking and/or increase the stopping distance. Either result may increase the risk of a vehicle crash.

Mitsubishi Fuso Truck of America (MFTA) is recalling certain model year 2005-2007 FE83D, FE84D, FE85D, and FG84D trucks; manufactured from May 27, 2004, through May 14, 2007. The fuel pipes may crack due to an improper manufacturing process. Additionally, the fuel pipe flare nuts may have been insufficiently tightened. Cracked fuel pipes or loose fuel pipe flare nuts may leak fuel. A fuel leak in the presence of an ignition source may result in a vehicle fire.
