2004-2012 Chevrolet Malibu, 2004-2007 Chevrolet Malibu Maxx, 2005-2010 Pontiac G6, 2007-2010 Saturn Aura
The Problem: Corrosion may have developed in the wiring harness for the body control module. This could cause the brake lamps to fail to illuminate, or to falsely illuminate when the brakes are not engaged. Other features like cruise control, traction control, stability control, and panic braking assist may also be disabled. GM is aware of 13 crashes and two injuries related to this problem.
The Fix: Dealers will modify the brake lamp wiring harness to prevent micro-vibrations from corroding the wiring harness. A technical service bulletin was issued for this problem in 2008, and GM conducted a small safety campaign for affected vehicles from the 2005 model year in 2009.
2005-2007 Chevrolet Corvette
The Problem: When the engine is warm, a defect in the electrical connector could cause it to expand, possibly bending the low-beam headlight relay control circuit wire. If the wire is repeatedly bent, it can break, meaning that the low-beam headlights will not illuminate.
The Fix: GM has not yet determined exactly how to repair affected cars, but it is possible that the underhood electrical center housing will be replaced.
Number of Vehicles Potentially Affected: 111,889 2005-2007 Chevrolet Corvette models. 2008-2013 Corvettes are subject to the same problem but are not part of the safety recall, but will be covered under a Customer Satisfaction Program. This means that dealers will inspect these newer cars for the possible defect as well at no cost to owners.
The Problem: In 2014 Chevrolet Malibu sedans equipped with the 2.5-liter four-cylinder engine and stop/start technology, a problem with the electronic brake control module may lose hydraulic brake boost, making for greater pedal efforts and longer stopping distances.
The Fix: Dealers will reprogram the electronic brake control module.
Number of Vehicles Potentially Affected: 140,067 2014 Chevrolet Malibu sedans equipped with the 2.5-liter four-cylinder engine.
2013-2014 Cadillac CTS
The Problem: If the vehicle is jump started while the windshield wipers are active, the wipers may become inoperable. This problem mostly occurs if the wipers are restricted by ice and snow.

Number of Vehicles Potentially Affected: 19,225 2013-2014 Cadillac CTS models.
2014 Chevrolet Silverado and GMC Sierra, 2015 Chevrolet Tahoe
The Problem: The tie rod threaded attachment to the steering gear rack may not be tight enough, meaning that the tie rod could separate from the steering rack, causing a loss of steering control.
The Fix: After dealers inspect the inner tie rods for the correct torque, the steering gear will be replaced if necessary. Owners are currently being contacted to have their vehicles taken by flatbed to dealers.
Number of Vehicles Potentially Affected: The defect was discovered and corrected during assembly, meaning that only 477 trucks and SUVs are affected. Notifications have already been sent to owners of affected vehicles.
