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 provide two replacement key rings and key cover on all ignition keys to correct this concern.
Chevrolet Malibu Recalls
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.
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.
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.
The heating, ventilation, and air conditioning system is referred to as the HVAC system. These vehicles are being recalled because when starting the vehicle the HVAC system may not work, preventing the windshield from defrosting when necessary. This could adversely affect driver visibility and increasing the risk of a crash. Dealers will update the HVAC control module software to correct this concern.
Vehicles equipped whit 8 way power adjustable front seats are being recalled because the wiring under the seat can become damaged from rubbing on the seat frame. Damaged wires could result in the seat not working correctly, smoke, or possibly a fire. Dealers will inspect, repair, and secure the affected wire harness to correct this concern.
The rear suspension is a collection of components that are bolted together, supporting the rear of the vehicle. During vehicle assembly, one or more bolts securing rear suspension components may not have been tightened to the correct specification. If one of these bolts were to loosen, sudden changes in the vehicle handling characteristics could result, increasing the risk of a crash. Dealers will inspect and re-tighten the bolts as necessary to correct this concern.
On vehicles equipped with a 4-speed automatic transmission, the tabs on the transmission shift cable end may fracture and separate. If this were to occur, the shift lever and the actual position of the transmission gear may not match. The driver would be able to move the shifter to "Park" and remove the ignition key, but the transmission gear may not be in "Park." The vehicle may not be able to be restarted and the vehicle could roll away after the driver has exited the vehicle, resulting in a possible crash without prior warning. Dealers will install a retainer over the cable end or replace the shift cable as necessary. The General Motors recall number 12106.
After an event of hard braking, the airbag control module (sensing and diagnostic module, or SDM) may reset itself. If this occurs during an aggressive turning maneuver, and if a potential vehicle rollover is sensed, the roof rail airbag may inadvertently deploy. Additionally, the airbags and/or seatbelt pretensioners may not deploy during a severe crash, increasing the risk of personal injury. Dealers will reprogram the SDM to correct this concern. The General Motors recall number is 12102.
