2012 GMC Sierra 3500 recalls
Passenger airbag inflator can explode, sending metal fragments
The passenger-side frontal airbag inflator in these vehicles uses a propellant that can degrade over time when exposed to high humidity, high temperatures, and repeated temperature changes.
Passenger air bag inflator may explode, sending metal fragments
The front passenger air bag inflator in these vehicles uses phase-stabilized ammonium nitrate propellant, which can degrade after long exposure to high absolute humidity, high temperatures, and repeated temperature cycling.
Fire extinguisher may clog or fail to discharge in a fire
Certain plastic-handle or push-button fire extinguishers installed in these vehicles may become clogged, so the extinguisher may not discharge as expected or may require excessive force to activate.
Fuel Tank May Overfill and Leak, Creating Fire Risk
A low fuel level sensor in the front fuel tank of these trucks may stick, causing the rear tank to overfill the front tank.

What owners report
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 wouldnât 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.
The service brakes lights has come on a d disabled my brake controller. This is a safety issue while towing and completely unacceptable.
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?
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.
WHILE DRIVING ON HIGHWAY, TRANSMISSION SHIFTS HARD TO HIGHER GEAR. THIS STARTED ALL OF A SUDDEN WILL TAKE TO DEALERSHIP. *JS
