Ignition Lock Actuator may Bind

NHTSA #14V827000 · Electrical System — Ignition · NHTSA notice

Reported December 30, 2014 · General Motors LLC

Potentially affected: 84,192 vehicles

Repair completion: 63.29% (latest rate the manufacturer reported to NHTSA; dataset updated November 3, 2026)

Manufacturer campaign 14696 and 14912 · Owners notified February 12, 2015 · Vehicles built May 17, 2011 – August 4, 2011 (per NHTSA)

General Motors LLC (GM) is recalling certain model year 2011-2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position.

Safety consequence

If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury.

Manufacturer remedy

GM will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The recall began on February 12, 2015. Owners may contact GM customer service at 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC).

Electrical System

ODI #11656297

Incident: April 23, 2025 · Filed: April 23, 2025

Odometer Fraud. The contact purchased a 2011 Chevrolet Avalanche. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 127,000, and at the time of registration, it was discovered that the mileage was 223,000. Local authorities had been contacted.

Suspension

ODI #11642582

Incident: February 12, 2025 · Filed: February 13, 2025

The contact owns a 2011 Chevrolet Avalanche. The contact stated while driving at an undisclosed speed and making a left turn, there was a loud banging sound coming from under the rear of the vehicle. The vehicle was steered to the side of the road and the steering wheel became stiff. The vehicle was towed to an independent mechanic but was not yet diagnosed. The contact believed that failure was associated with NHTSA Campaign Number: 10V643000 (Suspension); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 101,000.

Structure

ODI #11475560

Incident: July 24, 2022 · Filed: July 24, 2022

The structure that holds the rear differential and axle to the frame rusted through and broke off from both sides so the whole rear axle unit broke loose and pulled back so the drive shaft pulled loose and the rear tires were rubbing on the fenders. If this happened at highway speeds I don’t know what might have happened. The vehicle was towed to a welding shop to see if it can be repaired. It has not been inspected. If it can not be repaired the vehicle will have to be junked. There was no warning that this would happen.

Steering; Service Brakes

ODI #11444714

Incident: December 20, 2021 · Filed: December 22, 2021

Vehicle sometimes without warning, would shut down.Yes its available for inspection. Its unsafe because of the element of surprise when suddenly finding out that the ability to control the vehicle is dangerously compromised. Specifically when trying to steer or brake effectively or even trying to get to a safe location. With no warning there is not much time to react to the situation. In spite of having a perfect driver score I become a threat to other drivers and pedestrians when my vehicle shuts down. I have had it looked at by two different local mechanics. After trying a few less expensive options its becoming more evident that its a faulty sensor. After checking to see about other owners with similar issues, I have learned that the crankshaft position sensor was often behind the problem. This is not to say, it is in my case. My point is that with it posing a safety risk why should these other owners and Im sure more to come and me have to respond after possibly being in a deadly accident when this has been a documented as an ongoing problem. As for the rest of the questions, no one other than a mechanic has looked at the vehicle. Some times there would be an indication message on the dash along with engine trouble light and nothing would happen. But most recently it twice shut down without any indicator message. Once was on the highway the other about two hundred yards before a railroad crossing.

Air Bags

ODI #11429418

Incident: February 1, 2021 · Filed: August 17, 2021

February of 2021 I was notified the driver side air bag in my truck I drive daily has an issue that if goes off can cause serious injury or death. that as 6 months ago and still no path forward to fix it, how safe it this for me to drive is death is an option? I feel this would be a concern for drivers and the companies doing more to prevent something if a part cannot be secured. Maybe start offering deals to accept the trade ins so your customer doesn't have to drive around an unsafe vehicle because of supply issues? This needs to be addressed so something silly can be avoided.

Air Bags

ODI #11429025

Incident: February 26, 2021 · Filed: August 13, 2021

Was advised of the recall of my vehicle on Feb 26th 2021 and that the part to fix the problem was not available it is now six months later and have heard nothing and don,t know how log they expect people to wait with a faulty part to be repaired.

Air Bags; Unknown or Other

ODI #11413432

Incident: January 9, 2021 · Filed: April 22, 2021

DASHBOARD HAS 5 LARGE CRACKS 4 LATERAL AN 1 VERTICAL TOP FRONT SPEAKER HAS FALLEN OFF CLIPS.VEHICLE DASHBOARD STARTED CRACKING WHILE JUST SITTING OVER TIME AND WHILE DRIVING ROAD VIBRATION HELP CRACKING CONTINUE I'M AFRAID THAT WITH THE CRACKING SINCE IT IS IN THE PASSENGER AIRBAG AREA AS WELL IT COULD CAUSE AIRBAG TO DEPLOY CAUSING MORE DAMAGE INJURIES TO PASSENGER OR A WRECK BY SUDDENLY GOING OFF AND CAUSING DRIVER TO SWERVE SUDDENLY.

Unknown or Other

ODI #11390769

Incident: January 16, 2014 · Filed: January 30, 2021

DASH HAS SEVERAL LARGE CRACKS AND IT KEEPS GETTING WORSE WITH TIME

Air Bags

ODI #11376123

Incident: November 24, 2020 · Filed: November 24, 2020

I HAVE RECEIVED SEVERAL NOTICES ABOUT HAVING THE AIR BAGS REPLACED BUT THE LOCAL CHEV DEALER TELLS ME WHEN THEY GET THE PARTS THEY WILL CALL ME. WHEN WILL THE PARTS BE READY?

Power Train; Engine

ODI #11363964

Incident: October 11, 2020 · Filed: October 12, 2020

PURCHASED A USED 2011 CHEVY AVALANCHE WITH 87,000 MILES ONE OWNER FROM A SMALL DEALERSHIP. AFTER HAVING THE VEHICLE FOR ABOUT A WEEK NOTICED IT SHUDDERING WHEN PULLING ANY KIND OF GRADE. THINKING IT WAS SOME KIND OF MISFIRE HAD ALL THE PLUGS CHANGED ONLY TO FIND THAT IT ALSO HAD AN OIL FILE PROBLEM WITH 1 OF THE CYLINDERS. WHEN THE VEHICLE WOULD SHUDDER IT WAS AROUND 1500-2000 RPMS. IF I WOULD GIVE IT MORE GAS IT MADE IT PAST THE 2,000 RPMS AND WOULD SHIFT WITH NO PROBLEMS. NEEDLESS TO SAY THE TRANSMISSION IS NOW TOAST AS IT GAVE OUT COMPLETELY AND NEEDS REPLACED. NO WARNING LIGHTS OF ANY KIND MADE ME AWARE OF A POTENTIALLY SERIOUS PROBLEM. AFTER READING MORE I AM SEEING THAT THE TRANSMISSION IS SOMETHING THAT GM HAS NOT FULLY TAKEN CARE OF AS STATED WITH OLDER MODELS. THE TRANSMISSION FAILED WHILE DRIVING ON A MAJOR INTERSTATE ROADWAY WHILE NEARING THE TOP OF A HILL. IT JUST WENT COMPLETELY INTO NEUTRAL AND WOULD JUST REV THE ENGINE. THE TRUCK WAS CARRYING 3 ADULTS AND 2 CHILDREN IN CAR SEATS WHEN THIS OCCURRED. THANKFULLY WE WERE ABLE TO GET TO THE SHOULDER OF THE ROAD SAFELY. CURRENTLY THE TRUCK HAS 89,995 MILES ON IT. I ONLY PUT APPROXIMATELY 2000 MILES ON IT SINCE PURCHASE.
