2012 Gmc Sierra 1500 — Known Issues & Recalls

Your dashboard has developed cracks and has cracked again even after being replaced twice. The dashboard cracks appear to be recurring despite multiple replacements, and repairs are expensive at around $1,200 for the part plus $1,200 in labor costs. This issue may involve replacing the entire dashboard assembly or addressing an underlying defect causing the cracks to reappear.

You've noticed a crack in your dashboard above the instrument panel near the airbag. The crack started making noise and has gotten significantly worse over two weeks. You may need dashboard repair or replacement to address the cracking and noise.

Your dashboard is cracking in two places — on both the passenger and driver sides — and the cracks are getting worse over time. The cracks are starting to extend toward the airbag area. Fixing this would likely involve replacing the dashboard panel or having it professionally repaired.

Your dashboard has developed a crack near the passenger side airbag, close to the windshield, even though your vehicle has never been in an accident or had the airbags deploy. The crack appeared before the vehicle reached 50,000 miles. Fixing this would likely involve replacing the dashboard panel.

Your dashboard is developing cracks around the passenger airbag area, closer to the windshield. This is happening on a vehicle with only 32,000 miles and is just outside the manufacturer's 3-year warranty coverage. Repairing this will likely involve replacing the dashboard panel.

You have a crack in the dashboard on the passenger side of your vehicle. This occurred while the vehicle was parked and stationary. Fixing this will likely require dashboard replacement or repair, which may involve removing the dashboard panel and either repairing the crack or replacing the entire dashboard assembly.

Your dashboard is cracking above the instrument panel. This is a cosmetic issue that doesn't affect your vehicle's safety or performance, but it may worsen over time with sun exposure and temperature changes. Repairing this typically involves either replacing the entire dashboard panel or using a dashboard repair kit.

You purchased a 2012 GMC Sierra 1500 that showed 111,000 miles at sale, but the odometer reading was actually 243,000 miles when you registered it. The vehicle's service records show it was serviced at 149,000 and 179,000 miles, but the registration documents indicate those same mileage numbers, which doesn't match the actual mileage history. This appears to be odometer fraud, and you've filed a police report with the Dillon Police Department. Resolving this will likely require working with law enforcement and potentially pursuing legal action against the seller.

Your vehicle suddenly lost all electrical power while driving, causing you to lose control and collide with a guardrail. All warning lights on your dashboard illuminated at the moment of the failure. The vehicle regained power after the crash and was still drivable, but the underlying electrical problem was never diagnosed. This could involve issues with the battery, alternator, or main electrical connections that need professional inspection.

Your dashboard near the passenger side airbag has developed a crack. A dealer inspection determined that the entire dashboard needs to be replaced to fix this issue. The problem appeared at 22,000 miles.

Three of your four exterior door handles have stopped working when pulled from outside the vehicle, while the handles still work from inside. Two of these handles remain broken because of repair costs, which means two doors cannot be opened from outside—creating a serious safety concern if you need to evacuate quickly. The repair typically involves replacing the exterior door handle assembly on each affected door.

Your dashboard is developing cracks and has deteriorated to the point where it may need to be replaced. You're concerned that in a crash, broken pieces of the dashboard plastic could become a safety hazard to you and your passengers. Fixing this would involve removing and replacing the dashboard panel.

Your dashboard has developed a crack near the passenger side airbag. The dealer confirmed the dashboard needs to be replaced. The manufacturer offered to replace it at a discounted price, but the repair hasn't been completed yet.

While driving at highway speed, your truck's engine shut down completely, causing you to lose power steering and brakes. After pulling over, the truck wouldn't restart for several attempts over about 5 minutes, then finally started and ran normally except for the check engine light being on. The issue likely involves a fuel system, ignition, or electrical problem that needs diagnostic scanning to identify the root cause.

Your transmission unexpectedly downshifted, especially between second and third gears, while driving. You also noticed the check engine light coming on and off, and the engine felt like the engine mounts weren't working properly. The problem went away temporarily after restarting the vehicle, but happened again later. The dealer couldn't find the cause and didn't make any repairs. The issue may be related to engine mount failure, transmission control problems, or an engine sensor malfunction that needs diagnostic scanning and possible replacement.

Your 2012 GMC Sierra has a passenger side airbag that's subject to a safety recall. You've reported that GMC took longer than a reasonable amount of time to complete the recall repair.

Your dashboard has cracked around the airbag area, and you're concerned that in a collision, the airbag deployment could cause the entire dashboard to break apart or explode. The repair will likely involve replacing the dashboard panel and inspecting the airbag system to ensure it functions safely.

When driving at 50-60 mph or any speed, your tachometer needle jumps erratically and the engine surges, making it feel like the car might stall. This could indicate an issue with engine fuel delivery, ignition timing, or sensor malfunctions. A mechanic will likely need to scan for engine fault codes and inspect the fuel injectors, ignition system, and engine sensors.

Your dashboard has developed cracks throughout, particularly at all the attachment points where components are secured. This appears to be caused by the plastic material used in the dashboard not being protected against UV sunlight exposure. While this is primarily a cosmetic issue, the cracking at attachment points could potentially affect the structural integrity of panels.

I WAS DRIVING MY TRUCK UP A 6% PERCENT GRADE WHEN THE CHANGE FUEL FILTER SOON WARNING POPPED UP, ABOUT A MINUTE LATER THE VEHICLE STARTED TO LOSE POWER, I KEPT DRIVING TO TRY AND GET OVER THE HILL SO I COULD MAKE IT TO A REPAIR SHOP TO HAVE IT CHECKED OUT. I WAS ONLY ABLE TO MAKE IT ABOUT 2 MILES AFTER THE WARNING SHOWED UP BEFORE THE VEHICLE COMPLETELY SHUT DOWN AND WOULD NOT RESTART. (THERE WAS NOT ENOUGH ROOM ON THE SHOULDER TO PULL OVER ON MY SIDE THE ROAD SO I TRIED TO TURN ACROSS THE HIGHWAY WHERE THERE WAS AN EMERGENCY PULL OUT AND AS I DID THE TRUCK DIED SIDEWAYS RIGHT IN THE MIDDLE OF THE HIGHWAY, TAKING UP SEVERAL LANES OF TRAFFIC, FORTUNATELY THERE WAS ENOUGH INCLINE THAT I WAS ABLE TO ROLL BACKWARDS AND PULL OVER UP AGAINST THE GUARDRAIL) OF COURSE I HAD NO POWER STEERING OR POWER BRAKES SINCE THE TRUCK WAS NOT RUNNING. IT WAS A VERY DANGEROUS SITUATION! I WAS ABLE TO GET MY TRUCK TOWED TO THE LOCAL GM REPAIR SHOP WHERE THEY DETERMINED THAT THE FUEL PUMP HAD A CATASTROPHIC FAILURE AND HAD SENT ALUMINUM SHAVINGS THROUGHOUT THE ENTIRE FUEL SYSTEM. THEY SAID THE REPAIRS WOULD BE APPROXIMATELY $10,000 SO I CONTACTED GM AND DESCRIBED WHAT HAPPENED, AND THEY BASICALLY TOLD ME TO GO FLY A KITE. AFTER DOING SOME RESEARCH ONLINE IT LOOKS LIKE THERE HAS BEEN A MAJOR PROBLEM WITH GM TRUCKS WITH THE DURAMAX MOTOR FROM 2011-2016 AFTER THEY CHANGED THERE FUEL PUMP FROM THE CP3 HIGH VOLUME LOW PRESSURE PUMP TO THE CP4 HIGH PRESSURE LOW VOLUME PUMP. WHICH MEANS THE PUMP RUNS WITH LESS LUBRICATION WHICH RESULTS IN PUMP FAILURE, AND NOT JUST FAILURE BUT CATASTROPHIC FAILURE WHICH CAUSES MAJOR DAMAGE TO THE ENTIRE FUEL SYSTEM. I HAVE BEEN A LOYAL GM OWNER FOR OVER TWENTY YEARS, AND I AM EXTREMELY DISAPPOINTED THAT GM IS NOT WILLING TO MAKE IT RIGHT.
