Excess weight on the key ring can cause the ignition switch to move out of the run position without warning, turning off the engine. This defect can also affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. Dealers will install two 13mm key rings and key insert into the vehicle's ignition keys to correct this concern.
The driver may accidentally hit the ignition key with their knee, moving the key out of the run position, turning off the engine. If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, loss of power steering, and power braking, could increase the risk of a vehicle crash. Note: Until the recall has been performed, drivers should adjust their seat and steering column to allow clearance between their knee and the ignition key. Dealers will remove the key blade from the original flip key/RKE transmitter assembly, and provide two new keys and two key rings per key.
The Sensing and Diagnostic Module (SDM) that controls airbag deployment may experience an internal short circuit. This would result in deactivation of the airbags and seat belt pretensioners. If the airbags do not deploy as expected in the event of a crash, the risk of personal injury is increased. Dealers will replace the SDM on affected vehicles to correct this concern.
In the affected vehicles, there is a flexible steel steel cable that connects the seatbelt buckle to the front seat frame. Over time the cable may fatigue and separate. If the steel cable separates, the seatbelt may not properly restrain the seat occupant, increasing the risk of an injury in a crash. Dealers will inspect and replace the affected seatbelt buckles (lap pretensioners) to correct this concern.
Power assist to the braking system may be lost due to a problem with the vacuum assist, disabling the hydraulic boost assist. If this were to occur increased brake pedal effort would be required to slow and stop the vehicle, increasing the risk of a crash. Dealers will update the software in the electronic brake control module to correct this concern. Affected vehicles are equipped with a 2.5L engine with the auto stop/start option.
The underhood bussed electrical center (fuse box) can expand causing the low beam relay to flex. Over time this can cause the relay to fail, resulting in loss of low beam headlight operation. Loss of headlight operation can affect the drivers ability see and be seen, increasing the risk of a crash. Dealers will replace the underhood bussed electrical housing unit to correct this concern. 2008-2013 Chevrolet Corvettes will be covered under customer satisfaction program number 14203 for the same issue.
Increased resistance in an electrical connection at the body control module (BCM) may result in voltage fluctuations in the brake pedal sensor circuit. These fluctuations can cause concerns with various systems that monitor the position of the brake pedal, any of which would increase the risk of a crash. Dealers will attach the wiring harness to the BCM with a spacer, apply dielectric lubricant to both the BCM and harness connector and the BAS and harness connector, and will reprogram the brake pedal sensor to correct these concerns.
Certain vehicles equipped with 17 inch front brake rotors are being recalled because during vehicle assembly, brake rotors intended for the rear may have been installed on the front. The rear rotors, while the same diameter, are thinner and may result in a front brake pad detaching from the caliper. Braking ability would be reduced suddenly if a brake pad were to detach. The resulting increased stopping distance would increase the risk of a crash. Dealers will inspect the front brake rotors, and install the correct rotors with new brake pads, as necessary to correct this concern.
In order to help prevent rollaway type accidents, all late model vehicles are designed so that the transmission must be in park (or reverse for a manual transmission) before the ignition switch can be turned to the "off" position and the key removed. These vehicles are being recalled because the key can be removed when the ignition is not in the "off" position, increasing the risk of a rollaway type accident. Dealers will inspect the vehicle and replace the ignition lock cylinder as necessary. 2 new keys will also be supplied and programmed as required.
The vehicles being recalled are equipped with an electric power steering (EPS) assist system. The EPS can fail unexpectedly while driving. If this were to occur, steering ability would be maintained but much greater effort would be necessary to steer the vehicle, especially at slow speeds. One of four remedies will be applied depending on the model and year. Parts are not yet available so expect a second notification when they are.
