14V-614Oct 1, 2014
Electrical System

General Motors LLC (GM) is recalling certain model year 2013-2014 Cadillac CTS, Escalade, Escalade ESV, Chevrolet Suburban, Tahoe, GMC Yukon, and Yukon XL, and 2014 Buick Enclave, Chevrolet Express, Impala, Silverado HD, Traverse, GMC Acadia, Savana, and Sierra HD vehicles. In the affected vehicles, the chassis electronic module may be internally contaminated, resulting in an electrical short.

Risk and remedy

14V-355Jun 23, 2014
Electrical System:Ignition

This defect can 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. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.

Risk and remedy
Risk: 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, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), and 1-800-222-1020 (Chevrolet). GM's number for this recall is 14299.
13V-220May 24, 2013
Electrical System

General Motors LLC (GM) is recalling certain model year 2013 Cadillac ATS and model year 2013 Cadillac XTS; model year 2014 Chevrolet Impala; and 2013 Chevrolet Sonic vehicles. Originally, in May 2013, GM recalled 1,627 model year 2013 Cadillac ATS and model year 2013 Cadillac XTS; and model year 2014 Chevrolet Impala vehicles. In October 2013, GM informed the agency that it was adding model year 2013 Chevrolet Sonic vehicles to this campaign , representing an additional 8,050 units. The total number of vehicles being recalled is now 9,677. On the affected vehicles, the brake lamps may intermittently flash without the brakes being applied and the cruise control may disengage. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, "Lamps, reflective devices, and associated equipment."

Risk and remedy
Risk: If the brake lamps flash when the vehicle is not slowing, a following driver may not adjust vehicle speed when the vehicle is in fact braking, and the brake lamps are illuminating as intended, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will reprogram the body control module. The recall began on June 13, 2013. Owner's may contact Chevrolet at 1-800-630-2438 or Cadillac at 1-866-982-2339. GM's recall number is 13158.

What owners wrote

“My blind spot detectors went out, now as a result most of the electrical stuff no longer works. The car powers on and drains the battery randomly and the speedometer doesn’t work. Every light comes on from front camera, abs, and even power steering. I didn’t feel safe taking my kids to school and now I don’t feel I should pay $1,300 out of pocket.”

Should you keep driving it?

This page can't tell you that. 1 of 30 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
