Recall 18V-267: Equipment

Reported Apr 26, 2018 · 6,154 vehicles affected · General Motors LLC

Problem: General Motors LLC (GM) is recalling certain 2009-2014 Chevrolet Silverado HD and GMC Sierra HD, 2009 GMC Topkick 5000, 6000, 7000 and 8000 Series and Isuzu F Series, and 2009-2018 Chevrolet Express, and GMC Savana vehicles, equipped with certain Plastic-Handle Fire Extinguishers or Push Button 'Pindicator' Fire Extinguishers.

Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf

Risk: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.

Recall 17V-664: Fuel System, Gasoline

Reported Oct 19, 2017 · 35,292 vehicles affected · General Motors LLC

Problem: General Motors LLC (GM) is recalling certain 2011-2015 Chevrolet Silverado 3500 and GMC Sierra 3500 trucks equipped with dual fuel tanks. The low fuel level sensor for the front tank may stick causing the rear tank to overfill the front tank.

Risk: If the front tank overfills, the excess pressure may cause the front tank to expand and contact the driveshaft, possibly resulting in a hole in the tank. The hole will leak fuel, which in the presence of an ignition source, can increase the risk of a fire.

Fix: GM has notified owners, and dealers will replace the rear tank fuel pump or update the fuel-level sensor software, as well as inspect the front tank, replacing it as necessary, free of charge. The recall began December 11, 2017. Owners may contact GM customer service for Chevrolet 1-800-222-1020 or for GMC customer service at 1-800-462-8782. GM's number for this recall is 17399.

Recent 2012 GMC Sierra 3500 complaints

Owner reports filed with NHTSA, as written (personal details removed). Complaints are not verified by NHTSA.

Unknown or Other · reported Jan 8, 2026
Our Dash board cracked very badly from the top next to the speaker to the passenger side air bag. We purposely use a dash board cover and never place heavy things on it. This is a safety issue as if getting in an accident wouldn’t be bad enough flying shrapnel would be worse. We just had it fixed at a dealership to the tune of $2500. This is not okay as I see this is a constant problem.
Service Brakes · reported Mar 3, 2022
The service brakes lights has come on a d disabled my brake controller. This is a safety issue while towing and completely unacceptable.
Unknown or Other · at 35,900 miles · reported Oct 11, 2017
The gmc sierra 3500hd while in regeneration mode funnels exhaust directly into the cab through the vents. While GM recognized this as a flaw and came up with a fix for it, they will only repair it in a 5 year or 100,000 mile window. How is this not a safety issue without an expiration?
Power Train · at 150 miles · reported Feb 7, 2017
The vehicle will not shift properly when towing a trailer. While going up a hill, the transmission will not downshift properly. While going downhill, the vehicle downshifts to 2nd gear while going 60 MPH. I have contacted GM several times (They have it on file) that there is a problem with the transmission. They understand but said that they cannot do anything about it. This has been happening since it was brand new. Over and over again.
Power Train · at 31,200 miles · reported Feb 6, 2015
While driving on highway, transmission shifts hard to higher gear. This started all of a sudden will take to dealership.
