Accessories

On certain vehicles equipped with a Sure Power battery separator, internal circuit board capacitor failure may lead to overheating, smoke and/or fire during or following use. This may result in property damage and/or personal injury. Correction: Owners are advised to call Sure Power Inc at 1-855-450-3594 or e-mail recall@surepower.com to request a replacement battery separator.

Powertrain

On certain vehicles, the bearing surfaces of the extended lube universal joint that attaches the inter-axle driveline to the drive axle may become prematurely worn due to breakdown of the lubrification and/or excessive heat. Prematurely worn bearing surfaces may result in the u-joint becoming loose and/or binding. If undetected, the condition may result in universal joint failure, allowing the inter-axle driveline to detach from the axle, which may cause the vehicle to become disabled in the roadway. Lost propulsion, in conjunction with traffic, road conditions, and the driver's reactions, could increase the risk of a crash. In addition a driveline component separating from the vehicle could strike another vehicle, stationary object, or bystander, causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the interaxle driveline universal joint.

Engine

On certain vehicles equipped with a Caterpillar C15 engine, the Variable Valve Actuation (VVA) oil line may wear against the P-clip retaining the oil line. An oil leak could result in a vehicle fire causing property damage and/or personal injury. Correction: Caterpillar dealers will replace the VVA oil line with an updated version.

Emissions

On certain vehicles, the Aftertreatment Regeneration Device (ARD) may develop a hole allowing heat and flame to escape during a regeneration of the Diesel Particulate Filter (DPF). This condition could result in a fire causing property damage and/or personal injury. Correction: Dealers will affect repairs.

Fuel System

On certain vehicles equipped with Caterpillar C7 and C9 diesel engines, fuel pump failure can dilute the engine oil with fuel and cause the turbocharger to fail, leading to a loss of throttle control and excessive smoke. Either condition could result in a vehicle crash causing property damage, personal injury or death. Correction: Authorized Caterpillar dealers will replace the fuel pump.

Fuel System

On certain trucks, when the ignition key is in the 'ON' position, the pre-heater, located in the fuel filter base, is energized. If this pre-heater is energized while maintenance is being performed on the fuel filter, diesel fuel could ignite within the filter housing. A fire within the fuel filter housing may spread possibly resulting in property damage or personal injury. Correction: Dealers will inspect and, if required, replace the fuel heater assembly.

Other

On certain trucks, the axle housing may have been manufactured with steel that was out of specification (9.5mm thick instead of 11mm thick), which could result in a fatigue failure over time. If failure occurs, the axle may lock-up or the end of the axle could come off, which may result in a vehicle crash with injury or death. Correction: Dealers will inspect and, if required, replace the axles.

Suspension

On certain trucks, components used to attach the air suspension to the axle may contain elevated amounts of copper. The elevated copper content could result in component failure, which could cause erratic vehicle handling and a crash. Correction: Dealers will inspect and, if required, replace any suspect part with an updated version made with the correct metallurgical composition.

Engine

On certain vehicles equipped with a Caterpillar engine, the Variable Valve Actuation oil line (VVA line) used on 6 cylinder, 15L turbocharged and air-to-air aftercooled diesel engines may wear against the sharp edge of the cylinder head if not oriented correctly. Oil line wear may cause an oil leak and a potential fire hazard. Correction: Dealers will inspect and, if required, replace the VVA line.

Suspension

On certain vehicles, the rear suspension transverse beam castings were not made to specifications. If a casting were to break when the vehicle is in motion, parts could become projectiles with potential to cause property damage, personal injury or death. Also, the transverse beam may drop down low enough to contact the road surface causing sparks that could ignite a fire. Correction: Dealers will inspect and, if necessary, replace the transverse beams.

Brakes

On certain vehicles, the trailer ABS malfunction warning telltale indicator mounted on the dash does not comply with the requirements of CMVSS 121. The fluorescent light in the sleeper, when on, interferes with proper operation of the Power Line Carrier (PLC) trailer ABS signal, preventing the telltale from functioning. This ABS malfunction warning lamp is redundant to the existing trailer ABS malfunction indicator lamp located on the exterior of the trailer and visible from the driver side mirror. The indicator on the exterior of the trailer is not affected by this defect and will continue to warn the driver in the event of a trailer ABS malfunction. Correction: Since this does not pose any safety risk, no corrective action is required.

Steering

On certain vehicles, a longitudinal crack in the steer arm assembly may intersect a tapered hole that is machined into the part and used to mount the draglink ball stud to the steer arm. If this crack should propagate, the ball stud could become loose resulting in a loss of steering. Correction: Dealer will replace the knuckle and steer arm assemblies.

Suspension

On certain vehicles, the locking tab that locks the outer spindle nut onto the spindle was not engaged or properly bent over. Failure to properly engage the locking feature into the nut may cause the nut to loosen which will eventually cause the wheel bearing to over heat and fail if undetected. If the loose nut is not detected, the outer end (tire, wheel and hub assembly) could become separated from the vehicle. Correction: Dealer will inspect the hubs to determine if the locking tabs are properly bent.

Other

On certain vehicles, fatigue cracks can initiate in the weld joining the bracket pin to its mounting flange on the fifth wheel assembly. Weld failures could lead to the loss of the pin and the potential separation of the fifth wheel top plate from its mounting structure without warning. Correction: Dealers will replace the bracket pins.

Suspension

On certain vehicles, the ArvinMeritor FF98X series non-drive steer axle hubs may contain defects that could cause premature spalling of the affected bearings and eventually lead to a break down of the bearing. Correction: Dealer will replace the hub assembly.

Airbag

Certain heavy-duty trucks equipped with Meritor Wabco pneumatic antilock brake system (ABS) valve packages. The assembly bolts on these valve packages were not tightened correctly. Bolts torque below specification will not reliably prevent air leakage at the affected abs valve package interface joints once the component begins normal vehicle operation. If air leaks develop at any of the abs valve package interface joints, brake system pressure reductions could occur during braking or normal operation with units equipped with the traction control option, potentially extending stopping distances, possibly resulting in a vehicle crash. Correction: Dealers will tighten the fasteners to the proper specification.

Steering

Certain heavy duty trucks equipped with TRW tie rod ends on certain meritor axles. The tie rod and drag link ball stud ends contain bearings that are below the specified case depth and/or hardness. This can lead to premature wear with possible separation of the ball stud from the socket, increasing the risk of loss of control of the vehicle. Correction: dealers will remove and replace all affected tie rods and drag links with different designed ends.

Powertrain

Certain Peterbilt Class 7 and 8 tractors with interaxle driveshafts produced and supplied by Spicer Driveshaft, Inc. (SDI). The SDI driveshafts with universal joint cap bolts were not tightened to SDI's full torque specification. If the driveshaft assembly became separated from the retaining bolts, the interaxle could be ejected from the truck's driving axles, resulting in hazardous debris. This could occur with little or no prior warning to the vehicle's driver, and could also result in loss of vehicle power. Correction: Dealers will re-torque the retaining bolt fasteners.

Structure

On certain vehicles, a change in the internal linkage of cab doors has created a possible binding condition. If the linkage binds, full engagement of the door latch may not occur, allowing the door to open inadvertently. Correction: Dealers will modify the door linkage to correct the potential of binding.
