3. Filed Apr 4, 2025Failure Dec 29, 2024Milford, MIEngine

   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.

7. Filed Oct 11, 2023Failure Jul 28, 2023Goodyear, AZFuel/propulsion system

   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.

8. Filed Jul 17, 2023Failure May 12, 2023Queen Creek, AZEngine, Fuel/propulsion system

   I own a 2016 GMC 3500 Diesel that had a serious mechanical breakdown while traveling on the freeway. The truck lost all motive power and needed to coast across 4 freeway lanes. Once towed to a local GMC Dealer, they diagnosed the problem as the Bosch CP4 fuel pump internally came apart while driving. I have to have this vehicle working so I got it repaired at a cost of $16,145. This is a known issue and losing all power while at highway speeds could have caused a serious incident. Please address this issue before someone dies.

    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.

    Brake pedal has to be pushed almost all the way to the floor to stop, this recently changed from barely having to apply any pressure to the pedal. Took it to Quebadeaux gmc on 11-10-2021 and they inspected the brakes, said everything was good and that’s normal for the brakes to be that soft. That’s not normal or it would’ve always been like that.

    -ALL STARTED WITH LOUD POP, METAL FAILURE SOUND. -AT A STOP, WITH BRAKES APPLIED, THE POWER STEERING TURNS THE WHEEL TO THE RIGHT. I HAVE TO PULL TO THE LEFT TO KEEP THE WHEEL CENTERED. (NOT MOVING) THIS PRESSURE ISSUE WILL FINALLY STOP AND THE WHEEL WILL CENTER ON IT'S OWN. -STEERING HAS SLOP, FEELS LOOSE, DEAD CENTER -WHILE AT SPEED APPLYING THE BRAKES THE STEERING WHEEL WAS TORN FROM MY HAND 3 TIMES. THE POWER STEERING CAUSES TRUCK TO CHANGE DIRECTIONS WHEN BRAKING. 99% OF THE TIME THE TRUCK TURNS RIGHT. THE HYROBOOST SYSTEM IS TURNING THE STEERING SYSTEM TO THE RIGHT WHICH CHANGES THE DIRECTION OF THE TRUCK. -WHILE DRIVING THE POWER STEERING ASSIST APPEARS TO TURN OFF AND ON. AS IF THERE IS A POWER LOSS OR TOO MUCH POWER WAS APPLIED THAN IT RETURNED TO NORMAL. THE TRUCK HAS BEEN AT THE DEALER 3 DIFFERENT TIMES. FIRST DEALER VISIT THE TECH DEEMED THE TRUCK UNSAFE TO DRIVE. THIS WAS DETERMINED BY JUST DRIVING THE TRUCK FROM THE SERVICE LANE TO THE GARAGE. TECH IDENTIFIED A GM TSB (PIT5501D) TO INVESTIGATE THE ISSUE AND CONTACT GM. GM OUTLINED A REPAIR HOWEVER THE REPAIRS DID NOT RESOLVE THE ISSUE. I WAS TOLD BY THE DEALER TO TAKE IT TO ANOTHER DEALER FOR A SECOND OPINION. THIS WAS AFTER RETURNING TO THE DEALER FOR THE SECOND TIME AND STATING THE STEERING SYSTEM IS NOW LEAKING AND THE ISSUE STILL REMAINS WITH SOME IMPROVEMENT. 3RD VISIT AT THE 2ND DEALER: SECOND DEALER DROVE THE TRUCK WITH ME AND IT WAS DIFFICULT TO CONTROL. THE DEALER TECH WAS DRIVING AND I WAS SITTING IN THE PASSENGER SEAT. THEY DEEMED IT UNSAFE TO DRIVE AND PUT ME IN A LOANER. 2ND DEALER IDENTIFIED METAL IN THE STEERING FLUID AND PARTS THAT CONTAIN FLUID MUST BE REPLACE. PERSONAL THOUGHTS ARE THE STEERING BOXES ARE FACTORY DEFECTIVE AND CAUSING THEM TO FAIL OVER TIME. THIS THEN INTRODUCES METAL INTO THE HYDROBOOST SYSTEM WHICH RESULTS IN BRAKE AND STEERING FAILURE. *TR

    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.
