On certain motorcycles, oil cooler line clamps may have been incorrectly installed at time of assembly. This could cause an oil line to separate, which could drip or spray oil onto the rear tire, increasing the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect clamps and reposition or replace as necessary.
On certain vehicles with gasoline powered engines, the accelerator pedal could move laterally, allowing the accelerator pedal bracket to be hung up on the stopper bolt on the floor panel bracket. This would cause the accelerator pedal to remain in the open position, increasing the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will remove and replace the stopper bolt with a flanged plate that will be bolted to the floor bracket to prevent lateral movement of the accelerator pedal.
On certain vehicles, an underbody heat shield may not be long enough to protect the right drive half-shaft grease boot from heat. Over time, this could lead to a grease leak from the boot. If leaking grease comes into contact with heated surfaces of the exhaust system and/or diesel particulate filter (DPF), it could lead to a fire potentially causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will install a revised heat shield and certain vehicles will have the upper boost hose replaced.
On certain vehicles equipped with a 6-speed Aisin transmission, the left front halfshaft may disengage from the transmission and/or break. If this occurs, the vehicle would lose motive power and the park function, which could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the left front halfshaft for proper engagement in the transmission and replace the left front halfshaft if it is not properly engaged.
On certain vehicles, the rivet connections for the constant velocity (CV) joint of the rear driveshaft may have insufficient durability. Over time, this could cause the CV joint to break, resulting in a loss of propulsion which could increase the risk of a crash causing injury and/or property damage.
On certain vehicles, the seal between the rear differential and the axle housing could degrade due to contact variation. This could result in leaking differential oil. If the vehicle is operated in this condition, damage to the differential could occur, and could potentially result in noise, reduced motive power and rear axle lockup. These issues could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
