On certain vehicles equipped with a manual transmission, specific operating conditions (such as extreme temperatures, combined with high battery and accessory loads, and operation near engine stalling speeds), could allow the Engine Control Unit (ECU) to activate the engine stall prevention assist software which, in turn, could inadvertently command the hybrid system's electric motor to rotate the engine in the opposite direction, causing the vehicle to move in the reverse direction of that expected. This could result in a crash causing property damage and/or personal injury.
On certain Triumph Tiger 800 and Tiger 800 XC motorcycles, the engine could stall while the vehicle is decelerating. Engine stalling would result in lost vehicle propulsion which, in conjunction with traffic and road conditions, and the rider's reactions, could increase the risk of a crash causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will update the engine management software.
On certain BMW X5 xDrive35d (diesel) vehicles, the engine belt tensioner may have been manufactured incorrectly and could fail. This could cause a loss of steering power assist, which may result in a crash causing property damage and/or personal injury.
On certain motorcycles, a malfunctioning bank angle sensor may cause the engine to shut-off while the vehicle is underway. Engine stalling would result in lost propulsion which, in conjunction with traffic and road conditions, and the rider's reactions, could increase the risk of a crash causing property damage and/or personal injury.
On certain 2000-2004 ML55 AMG and 2000-2002 ML-Class vehicles, the cruise control may fail to disengage if the plunger within the brake lamp switch become immovable. The driver would, however, be able to disengage the cruise control by other means such as; pushing the cruise control stalk towards the instrument cluster, or by applying adequate amount of brake pedal force to achieve a specified deceleration rate. Failure or delay in disengaging the cruise control can increase the risk of a crash causing property damage and/or personal injury.
On certain vehicles, a spring in the lost motion spring assemblies in the variable valve timing and lift electronic control (VTEC) system may bind. As a result, the lost motion spring could fracture. In the worst case parts from a broken spring could become caught in the camshaft, causing the engine to stall without the ability to be restarted. Lost propulsion from the engine, in conjunction with traffic and road conditions, and the driver's reactions, may increase the risk of a collision causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will inspect and, if necessary, replace the four lost motion spring assemblies."
On certain vehicles, the tension adjuster pulley for the drive belt, which operates the alternator, water pump, air conditioner compressor and power steering pump, may contain an improperly manufactured internal spring that can break due to repeated stress. Should the spring break, this would cause the drive belt tension to be maladjusted, allowing the belt to slip. If the belt comes off, the loss of steering power assist would require the driver to exert increased effort to steer the vehicle. This could result in a crash causing property damage and/or personal injury. Additionally, the loss of water pump function would cause the coolant temperature to rise, which can lead to engine overheating, while the loss of alternator charging ability would lead to battery discharge and eventual engine stall.
Safety Risk
No risk description available.
Remedy
Dealers will replace the drive belt tension adjuster pulley.
On certain motorcycles, the engine could stall while downshifting or maneuvering with the clutch disengaged and the engine at idle. Lost propulsion (engine stalling), in conjunction with traffic and road conditions, and rider's reactions, could increase the risk of a crash causing property damage and/or personal injury.
On certain motorcycles, the engine oil filler plug/dipstick may be of an incorrect length. As a result, the accuracy of the dipstick may be compromised and adequate oil levels may not be maintained. Incorrect oil level may cause the engine to fail and seize. Lost propulsion, in conjunction with traffic and road conditions, and the rider's reactions, could increase the risk of a crash causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will replace the affected oil filler plug/dipstick.
On certain vehicles, the bolt that connects the engine lubrication oil pipe to the vacuum pump may not have been tightened properly during vehicle assembly. If not adequately tightened the bolt may loosen after prolonged vehicle operation, which can result in oil seepage or leakage from the packing seals. Normally, as oil is lost, the oil warning lamp will illuminate and there may be abnormal engine noise. However, if the problem is not addressed, the loss of oil can cause engine seizure. If the engine seizes while the vehicle is being driven, the vehicle may experience sudden deceleration, which could result in a crash causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will replace the packing seals and tighten the bolt to specified torque.
On certain vehicles, the engine and transmission software calibration is too sensitive. When the driver brakes during city driving, and/or releases the accelerator pedal, the engine idle speed may drop resulting in a sudden engine stall without any prior warning. Engine stalling could, in conjunction with traffic, road conditions and driver's reactions, increase the risk of a vehicle crash causing property damage, personal injury or death.
On certain vehicles the Intelligent Power Distribution Module (IPDM) assembly contains an Engine Control Module (ECM) relay that has a diode for electrical current noise reduction. The ECM relay may allow silicon vapor to form and over time the silicon evaporates from the diode molding which causes silicon oxide to develop on the ECM relay contact due to arcing. In certain instances, this oxidation could cause engine performance issues (hesitation, rough engine idle, slow start/no-start condition), and engine stalling at low engine speeds which may result in a crash.
Safety Risk
No risk description available.
Remedy
Dealers will replace the Engine Control Module (ECM) relay.
On certain vehicles equipped with a 1.8L MFI engine and a two-wheel drive transmission, the Engine Control Module (ECM) may have been improperly manufactured. There is a possibility that a crack may develop at certain solder points or on varistors on the circuit board. In most cases, if a crack occurs at certain points or on certain varistors, the engine warning lamp could be illuminated, harsh shifting could result, or the engine may not start. In some instances, if cracking occurs on particular solder points or varistors, the engine could stop while the vehicle is being driven, increasing the risk of a crash causing personal injury.

Remedy
Dealers will inspect and, if necessary, replace the ECM.
On certain vehicles equipped with a 1ZZ-FE engine and a two-wheel drive transmission, the Engine Control Module (ECM) may have been improperly manufactured. There is a possibility that a crack may develop at certain solder points or on varistors on the circuit board. In most cases, if a crack occurs at certain points or on certain varistors, the engine warning lamp could be illuminated, harsh shifting could result, or the engine may not start. In limited instances, if cracking occurs on particular solder points or varistors, the engine could stop while the vehicle is being driven, increasing the risk of a crash causing personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will inspect and, if necessary, replace the ECM.
On certain vehicles, the spring plate which is mounted at the oil filler neck and fixes it at the cylinder head cover may crack and result in an engine oil leak in the engine compartment. In addition to possible damage to the engine caused by inadequate lubrication, this may result in leakage of oil onto the road surface unintentionally causing a traffic accident.
Safety Risk
No risk description available.
Remedy
Dealers will replace the affected oil filler necks.
On certain motorcycles, the throttle cable may contact, and chafe against, the upper edge of the radiator. A chafed cable may affect the throttle operation and could cause it to become inoperative or seize open. Should this occur while the motorcycle is in motion, it could result in a crash causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will secure the throttle cable to the frame.
On certain Sprinter 2500 and 3500 vehicles, the spring plate which is mounted at the oil filler neck, and fixes it at the cylinder head cover, may crack and cause an engine oil leak. In addition to possible damage to the engine (caused by inadequate lubrication) this may result in leakage of oil onto the road surface.
On certain vehicles, the material composition of the engine valve springs may include micro-foreign objects, which may compromise the strength of the valve spring, causing the spring to degrade and break. If a valve springs breaks, abnormal noise and rough engine performance will be noticed and, in the worst case, the engine could fail and stop suddenly while the vehicle is in motion. A sudden engine failure would result in lost propulsion which, in conjunction with traffic, road conditions, and driver's reactions, could increase the risk of a crash causing property damage, personal injury or death.
On certain vehicles, the tension adjuster pulley for the drive belt which operates the power steering pump and air conditioner compressor (if equipped) has an outer portion that is made of plastic. Repeated heat stress can cause the plastic material to deteriorate and pieces of the pulley can break off. Broken pieces of the pulley can get caught between the pulley and the drive belt, causing the drive belt to come off and resulting in the driver needing increased effort to steer the vehicle. This situation could result in a crash causing property damage, personal injury or death.
Safety Risk
No risk description available.
Remedy
Dealers will replace the power steering pump drive belt tension adjuster pulley.
On certain vehicles equipped with a 2.8L V6 engine, if low octane (regular) fuel is used in the vehicle instead of the required high octane (premium) fuel, as stated in the owner manual and on the fuel filler door, the combination of regular fuel usage and aggressive driving maneuvers may induce pre-ignition. If pre-ignition occurs, the driver will hear a pinging or knocking sound from the engine, and if the vehicle continues to be driven after the onset of this noise a connecting rod or piston may break, resulting in engine failure which would disable the vehicle, increasing the risk of a crash causing property damage, personal injury or death.
