2016 GMC Sierra 3500 Problems

When braking, the service trailer brake system message and service stabilitrac message appear on the dash and brake pedal gets soft to hard repeatedly and truck pulls from side to side violently as if one side of the trucks brakes are working and the other side is not.

BACKED IT OUT OF THE GARAGE TO GO SOMEWHERE, GOT ON THE MAIN ROAD AND IT WAS WONDERING WITH A LOT OF PLAY IN THE STEERING WHEEL, NEXT HIT A BUMP IN THE ROAD AND THE FRONT WHEELS STARTED SHAKING UNCONTROLLABLY UNTIL I SLOWED TO UNDER 40 MPH, HIT ANOTHER ROAD SEAM AND IT DID THE SAME THING.TOOK IT TO THE MECHANIC, HE DIAGNOSED IT AS A FAILED STEERING BOX. TRUCK ONLY HAS 27,500 MILES ON IT. NEVER SEEN A DIRT ROAD, NOT DRIVEN IN THE WINTER.$1700.00 LATER ITS FIXED. MANY COMPLAINTS ABOUT THIS ON THE INTERNET AND GMC HAS NOT RECALLED THESE TRUCKS FOR THIS PROBLEM THEY KNOW ABOUT. HAS SOURED MY TRUST IN THEIR BRAND.

Driving down the road and I got a service trailer brake code pop up and would not go away and kept dinging It is very distracting and sometimes causes the trailer brakes to malfunction

The contact owns a 2016 GMC Sierra 3500. The contacted stated that while her husband was attempting to start the vehicle, the contact stated that after five minutes the engine independently failed while the vehicle was running. No warning light was illuminated. The vehicle was towed to an independent mechanic where it was diagnosed and determined that the fuel system and fuel pump needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure but offered no assistance. The contact was transferred to the NHTSA Hotline to report the failure. The approximate failure mileage was 100,000.

Driving my vehicle in the mountains pulling a 16000 lb 5th wheel trailer, the engine goes into Reduced Engine Power due to a Turbo Vane Position sensor / Turbo Over Boost or Under Boost fault. This has happened 4 times in the last 3 months and has nearly caused an accident following each occurrence. The vehicle is a 2016 GMC Sierra 3500HD with the 6.6L LML Duramax Diesel engine with 75000 miles. I believe the Reduced Engine Power protection is far to abrupt in the loss of Engine Power to safely move the vehicle out of the flow of traffic. During each occurrence I was in the left lane of a 2 lane expressway attempting to pass a much slower vehicle going up a 5-8% grade and was unable to complete my pass due to the loss in propulsion which nearly caused an accident.

Bosch CP4 fuel pump failure that shut down vehicle while driving, luckily did not cause an accident. Would not restart. Damaged entire fuel system including injectors and now have $17,000 in damage that needs repaired.

This is a 2016 GMC 3500 Denali truck with 70,000 miles on it. The Bosch fuel pump threw metal shavings into the fuel system. This is a known issue with GMC trucks with a Bosch CP4 fuel pump for 2011-2016. The engine suddenly quits running leaving the driver without power steering or power brakes. It happened to me when pulling a 14,000-pound 5th-wheel RV. Fortunately, I was on an interstate outside of Grand Junction CO and the road was flat. If I had been in the mountains going downhill and the engine quit I'd likely caused an accident perhaps fatal. GMC quoted me $16,000 to repair. Again, this is a known issue at GMC but they refuse to do anything about it. GMC Dealership in Grand Junction performed the analysis and advised me to drive it home to Phoenix. I got 60 miles when the engine quit. Cost me $1,600 to get the truck returned to my GMC Dealer in Phoenix and another $1,600 to get my trailer back home.

I had the rear defrost running, and began to hear a sizzling/hissing sound in the back seat. After a minute of hearing this noise, I noticed smoke coming from the rear sliding window. I immediately turned off the rear defrost. A few seconds later, I heard a loud pop and the passenger side of my rear window was shattered. I called and spoke with the dealership and explained what had happened. They said they knew exactly what had happened and it is pretty common in these trucks.

Vechicle is giving codes of Emissions warning, P0102, P154B and P154D

SIDE THORAX AND HEAD CURTAIN AIRBAGS ARE LISTED AS STANDARD EQUIPMENT FOR THE 2016 GMC SIERRA TRUCK LINE. I DISCOVERED AFTER MY PURCHASE THAT MY VEHICLE DOES NOT HAVE SIDE AIRBAGS. AFTER RESEARCH I LEARNED THAT WHEN YOU SELECT THE DURAMAX ENGINE OPTION, GMC DELETES ALL SIDE AIRBAGS AND DOES NOT NOTIFY THE CUSTOMER. IT IS DIFFICULT TO DETERMINE IF YOUR VEHICLE HAS SIDE AIRBAGS OR NOT. SO THE BOTTOM LINE IS THAT POSSIBLY THOUSANDS OF CUSTOMERS BELIEVE THEY HAVE SIDE AIRBAGS (LIKE MYSELF) BUT IF THEY SELECTED THE VERY POPULAR (AND QUITE EXPENSIVE) DURAMAX ENGINE OPTION, THEY DO NOT HAVE THE SIDE AIRBAGS AS ADVERTISED. THIS IS A CRITICAL SAFETY FEATURE THAT GMC IS DELETING FROM ADVERTISED STANDARD EQUIPMENT WITHOUT PROPERLY ADVISING CUSTOMERS. IT WOULD BE A TRAGEDY IF SOMEONE IS INJURED IN A VEHICLE THEY BELIEVE HAS SIDE AIRBAGS BECAUSE OF THE DECEPTIVE PRACTICE. THIS POSSIBLE AFFECTS OTHER YEARS AND POSSIBLY THE CHEVROLET SILVERADO ALSO.
