On certain vehicles, the snap ring on the automatic transmission’s primary clutch drum could move out of position, which could cause a sudden loss of power transfer. Loss of vehicle propulsion, in conjunction with traffic, road conditions and the driver’s reactions, could increase the risk of a crash causing property damage and/or personal injury.
On certain vehicles equipped with automatic transmissions, a defect in the PARK function could allow the vehicle to roll away while in PARK, or to immobilize the vehicle so that is cannot be moved or driven. Should the vehicle roll away, it could strike another vehicle, stationary object, or a bystander, causing property damage and/or personal injury.
On certain four-wheel drive vehicles, due to insufficient welding of the front differential housing to the axle tubes, the housing may rotate relative to the axle tubes while the vehicle is operated in four wheel drive. This could allow the front driveshaft to bind up and fracture, causing a loss of motive power and damage to surrounding components if the driveshaft continues to spin. This could increase the risk of a crash causing personal injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
dealers will repair or replace the front axle assembly on affected vehicles.
On certain vehicles, manufacturing defects could cause internal shorts or current leaks to develop within battery cells, which could result in reduced voltage, the illumination of the EV system warning lamp and a loss of motive power, increasing the risk of a crash. Electrical shorts could also result in thermal damage to battery cells and surrounding components, increasing the risk of a fire. Both these issues could cause personal injury and/or damage to property.
On certain vehicles, the accelerator pedal arm may fail. This would cause the throttle control to return to the idle position, causing a reduction in engine power and propulsive force. Loss of vehicle propulsion, in conjunction with traffic and road conditions, and the driver’s reactions, could increase the risk of a crash causing property damage and/or personal injury.
Certain trucks equipped with an automatic transmission could experience a sudden transmission failure. This would result in a loss of vehicle propulsion which, in conjunction with traffic and road conditions, and the driver’s reactions, could increase the risk of a crash causing property damage and/or personal injury.
On certain vehicles equipped with a full-time four-wheel drive system, the transfer case controller could fail. This could cause the transfer case to shift into or through the neutral position, which may allow the vehicle to roll away, even with the transmission in the PARK position. Should the vehicle roll away, it could strike another vehicle, stationary object, or a bystander, causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the final drive controller with updated software.
On certain vehicles, the tunnel heat shield may drop down and rub on the drive shaft, which could eventually result in the drive shaft breaking and loss of motive power. In conjunction with traffic and road conditions and driver reactions, this could increase the risk of a crash. A broken drive shaft could also impact the tunnel with sufficient force to cause airbag deployment. Unintended airbag deployment, in a non-warranted (non-impact) situation could startle the driver which could result in a vehicle crash causing property damage and/or personal injury. In some instances, inadvertent deployment could cause minor injuries to vehicle occupants.
Safety Risk
No risk description available.
Remedy
Dealers will install a heat shield support bracket.
On certain vehicles, the transmission may shift from Driver Shift Control (manual) to Sport (automatic shifting) unexpectedly. If the driver was slowing the vehicle using DSC (manual) mode to achieve engine braking, engine braking would be cancelled without warning. In conjunction with traffic and road conditions, and the driver’s reactions, this could increase the risk of a crash causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the transmission control module.
On certain vehicles, the transmission lever gear selector plate lock clip may have been installed incorrectly during vehicle assembly. Over time, the clip could disengage from the steering column bracket, allowing the transmission cable to move out of position. If this occurs, the transmission shift lever will not match the actual gear position. The driver would be able to remove the key from the ignition, even if the transmission is not actually in the PARK position. This could allow the vehicle to roll away, which could result in a crash causing personal injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will inspect and, if necessary, reposition the clip.
On certain vehicles, the rear axle pinion nut could loosen and allow the rear driveshaft to detach from the axle, or fully detach from the vehicle. Pinion nut separation could also cause the rear axle differential to fail suddenly, causing rear wheel lockup. These issues could result in loss of propulsion, danger to other road users, loss of vehicle control and possible crash causing property damage and/or personal injury.
On certain motorcycles, transmission oil pressure may be too high, causing the output shaft sealing ring to leak. Oil leakage ahead of the rear tire could render the vehicle unstable. This could result in a crash causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will install an oil restrictor to reduce oil pressure at the transmssion output.
On certain vehicles, the ignition interlock blocking mechanism could become damaged if excessive force is applied to the ignition key. If this occurs, it may become possible for the driver to remove the ignition key when the gear selector is in a position other than the Park position. This could allow the vehicle to roll away, increasing the risk of a crash causing personal injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will install an updated ignition interlock lever and replace the ignition lock cylinder if necessary.
On certain vehicles, the electrical water pump assembly, used to circulate coolant through the hybrid components, may fail. If this were to occur, coolant would stop circulating, illuminating various warning lights in the instrument panel of the vehicle. In certain cases, the water pump motor could short-circuit, causing the hybrid system to stop functioning and the engine to stall. A loss of propulsion, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing personal injury and/or property damage.
On certain vehicles equipped with the Comfort Access option, if the driver depresses the start-stop button multiple times in rapid succession, the transmission could shift to Neutral (N) instead of Park (P). If the driver leaves the vehicle without engaging the parking brake, a sufficient slope could cause the vehicle to roll away. A rollaway vehicle could strike another vehicle, stationary object, or a bystander, causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the Central Gateway Control Module with updated software.
On certain vehicles built between July 1, 2009 and November 30, 2009, the rear axle pinion nut may have been incorrectly manufactured and could loosen. If the pinion nut was to separate from the pinion, the rear driveshaft could become detached from the rear axle, or fully detached from the vehicle. Pinion nut separation could also cause the rear axle differential to fail suddenly, causing rear wheel lockup. These issues could result in loss of propulsion, danger to other road users, loss of vehicle control and possible crash causing property damage and/or personal injury.
Some motorcycles may be equipped with drive chains that contain improperly heat-treated outer drive plates that may break during use. If a chain outer drive plate were to break, the motorcycle could unexpectedly lose driving force, increasing the risk of a crash causing personal injury and/or property damage.
