"Faulty fuel pump driver module" part Not available for inspection. Repaired at dealership and they kept the part. While driving 75 mph on the interstate during high traffic time my GMC Sierra 3.0 diesel truck engine shut completely down, not just once but on several occasions putting myself and three other in a life safety situation due to the traffic around us at the time. I had to navigate the truck through traffic and off the road. Once there the vehicle was turned off allowed to sit for a few minutes and restarted. The vehicle would restart and we continued only to have this scenario repeated again several times. Faulty fuel module was diagnosed by mechanic at dealership and replaced. Part was not inspected by no one to my knowledge except the mechanic. There was no prior warnings before this incident happened. …
Unloaded my Denali at huge loss with 30,000 miles because gm wouldn't fix recall after many times in shop, broke down on freeway, and need to travel to Canada on business. Canada won't allow vehicles with open safety recalls to enter country even though im pretty sure engine was MADE in Canada. Gm corporate office told me there's nothing they can do. While in shop for 4 days of testing i watched vehicle on app, never started, moved, just put out back for 4 days then told absolutely nothing. Just wanted fair trade in for diesel. Truck looked identical to brand new on lot, 10/10 except engine recall. Gm promised to reimburse rental fees when broke down a week or so, submitted documents to Gm, nothing recieved. Bought ram instead for obvious reasons. Is there a lemon law, class action, agency etc that can help compensate for losses? The public should be warned!
On November 16, while driving on the highway, my GMC vehicle suddenly lost engine power without warning. I was forced to stop in traffic, creating a dangerous situation and putting my life at risk. The vehicle required towing and has remained at the dealership since that date. The dealership determined that the engine requires replacement. Repairs have been significantly delayed, including an incorrectly ordered replacement engine, and the vehicle remains out of service more than two months later. This defect caused a sudden loss of power while driving and presents a serious safety concern.After the incident, I contacted the dealership immediately. Diagnostic appointments were scheduled and then canceled by the dealership twice, which delayed inspection and repair. I was only able to leave the vehicle at the dealership on December 12 due to these delays.
My daughter and I drove to town to run some errands, we live twenty-three minutes away and take the freeway. Speed limit on that specific section of the freeway (I80) is 80mph. As I was taking the on-ramp to enter traffic, My GMC started shifted very hard and losing power. The vehicle was sputtering and making strange sounds. I was unable to exceed 60mph due to excessive vibrations/shaking the vehicle. Steering was starting to be difficult at the same time I noticed Oil Pressure Gauge slowly dropping on instrument panel below 25psi. I had to pull over immediately. oil pressure remained lower than normal, verified Oil was filled to manufactures specifications (changed June 30, 2025). Returned the vehicle to my place of residence as safe and slow as I possibly could and parked it as it is a major safety concern.
The Dynamic Fuel Management (DFS) is causing damage to lifters, valves, camshafts, and connecting rods. I received a recall notice from GMC on the GMC app, stating "L88" Engine loss of Propulsion or Related field action: Special coverage N252494003. The connecting rod and/or crankshaft engine components have manufacturing defects that can lead to engine damage and engine failure. My 22' GMC 1500 has just over 30k miles, and issues are starting with the previously mentioned engine parts. A "pico" test was completed at approx 20k miles. Too early and not enough mileage to show the true damage caused by the "DFM" Dynamic Fuel Management.
My truck went into "limp" mode and had very little power. It was towed to the dealership where they diagnosed the issue as a bad solenoid causing the engine misfires. The solenoid was replaced, but the issue was not fixed. Now the dealership is stating the engine has bent lifters and the repairs will not be covered under the ongoing massive engine recall. The vehicle had the pico test on 9/17 and it "passed", but less than 3k miles later and the engine failed. This is a clear safety issue and well known by NHTSA and GM. Now I'm negotiating with the dealership to cover repairs and my truck has been gone nearly a month.
Driving 70 mph on highway and the engine shut off. Dash says shift to park to restart. Pulled over and put the vehicle in park and pressed engine start. Vehicle did not start back up. (No crank no start) Vehicle locked in park and wont shift. Vehicle was towed to my house. Replaced battery bus bar and vehicle started back up. Test drove and shut off again in my driveway. Will not restart. No engine light on. 124k miles on it. No warning of this happening. Vehicle randomly will shut off. Sometimes it turns on. Been parked since January in my garage for safety concerns until I learn of a repair.
