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.
The passenger front air bag may not deploy in a crash due to a faulty weld in manufacturing. Dealers will replace the passenger front air bag free of charge to resolve the concern.
The driver's front air bag has a shorting bar which may intermittently contact the air bag terminals. This would cause the air bag to not function as designed in an accident. Dealers will replace the steering wheel air bag coil free of charge to resolve the problem.
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.
The daytime running light module may overheat and melt, resulting in the potential of vehicle fire. Dealers will repair vehicles free of charge (a repair is not available as of the time of this writing).
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 tie rod where it threads into the steering gear rack may not be tightened enough. Dealers will inspect the inner toe rods to make sure they are correctly tightened, replacing any defective steering gear as necessary free of charge to resolve the concern.
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.
