The National Highway Traffic Safety Administration (NHTSA) has issued the following recalls:
* On certain Ford model year 2008 through 2009 F-650 and F-750 trucks equipped with Caterpillar C7 engines, the #5 and #6 fuel lines may crack at the fastening point to the common fuel rail and cause a fuel leak. A fuel leak, in the presence of an ignition source, can result in a vehicle fire.
* The actuation and release timing of certain Mack model year 2008 through 2011 GU and MRU model vehicles manufactured with a front tow glad hand option from October 22, 2007 through June 30, 2010, exceeds the limit which fails to conform to the requirements of Federal Motor Vehicle Safety Standard No. 121, “Air Brake Systems.” If the brakes do not perform as they should, a vehicle crash could occur.
* On certain Navistar model year 2010 and 2011 International LoneStar heavy trucks manufactured from June 11, 2008 through June 14, 2010, equipped with styled aluminum wheels and feature code 27DRS or 27DRT, the wheels may develop cracks in the spokes. The cracks may progress over time to the point of wheel failure possibly resulting in wheel separation from the vehicle. Wheel separation increases the risk of a crash, which may result in property damage, personal injury or death.
* One of the four harness spade terminal connections to the chassis load center on certain Kenworth model year 2011 T660, T800, W900, C500, T440 and T470 vehicles manufactured from April 1, 2009, through August 30, 2010, may become completely unseated. A completely unseated connection may result in a power loss to a portion of the vehicle’s exterior lighting. Power loss of the vehicle’s exterior lighting may reduce the visibility of the vehicle to other drivers increasing the risk of a crash.
* There is a manufacturing defect in the seal supplied by a component manufacturer installed on the output shaft of the exhaust gas recirculation (EGR) valve actuator on certain Kenworth and Peterbilt vehicles, which may cause eventual delamination of the seal. Delamination of the seal may allow engine oil to leak from the EGR valve onto exhaust components. The leaking of engine oil onto hot exhaust components, such as when the engine is under significant load, may create the possibility of a fire.
* Certain Navistar model year 2011 International 7300, 7400 and 7500 vehicles may fail to comply with the requirements of federal motor vehicle safety standard No. 108, “Lamps, Reflective Devices, and Associated Equipment.” These vehicles are installed with improper headlight height of 55.5 inches and the correct height should be 54 inches. Improper height on the headlights may not fully illuminate the road surface or may inhibit the ability of motorists to see vehicles, which can increase the risk of a crash.
* Certain Daimler Trucks model year 2008 through 2011 Saf-T-Liner C2 and Saf-T-Liner HDX school buses manufactured from October 5, 2006 through May 24, 2010, equipped with EPA 2007 MBE 900 Detroit Diesel engines may have software problems. Engine software may not react properly to certain aftermarket treatment device fault codes. The software may unnecessarily shutdown a vehicle or may fail to shutdown a vehicle with an aftermarket device over-temp fault. Unexpected shutdown of a vehicle may increase the risk of a crash. Overheating of the aftertreatment device without engine shutdown may result in a fire.
* There may be a software issue on certain model year 2007 through 2010 Freightliner Business Class M2, Custom Chassis MT45, S2 Chassis and Stering Acterra vehicles manufactured from October 5, 2006 through May 24, 2010, equipped with EPA 2007 MBE 900 Detroit Diesel engines. Engine software may not react properly to certain aftermarket treatment device fault codes. The software may unnecessarily shutdown a vehicle or may fail to shutdown a vehicle with an aftermarket device over-temp fault. Unexpected shutdown of a vehicle may increase the risk of a crash. Overheating of the aftertreatment device without engine shutdown may result in a fire.
* ArvinMeritor suspension systems on certain Great Dane MPA20, MPA38 and MPA40 trailers may have missing welds at the interface of the lower seat bracket and axle beam. Missing welds could allow the axle to roll out of position and potentially impact the handling of the trailer such that a driver may lose control of the vehicle, increasing the risk of a crash. n
