It was determined by the parts manager at DeBauche Truck and Diesel that the rear wheel hub nut had come loose and destroyed the threading. The damage was catastrophic, in that continued use of the vehicle may result in an accident and the vehicle cannot be driven until remedied. GM customer satisfaction program released a notice dated January 2018 for this specific safety issue. Reference number N172120230. A replacement axle cost was 2078.35 with additional parts and labor to be determined. Vehicle was purchased 8/29/2025 from Morrie's West Salem with no indicated reports of the issue through carfax and no related recalls through nhtsa. The vehicle had 30,967 miles at time of purchase.

    The vehicle had a shudder when I first bought it and towed a boat. Around 60-70 it felt like a tire out of balance. The truck is stock no alterations. New tires and the vehicle has the same shudder. Had the tires balanced three times at different tire shops with no correction. I was getting my oil changed and the shop suggested a transmission and transfer case oil change. Once they looked up my vehicle they told me I would have to go to a dealer for the transmission oil change. I brought my vehicle to a GM dealer for the transmission oil change. They diagnosed my vehicle with a bad transmission causing the shudder with the only fix a new transmission at $7,800. I have yet to replace my transmission. Reading only thousands of GM owners complaining about the transmission issues. Two other types of transmission have had recalls and fixes but this version no fix. GM knowingly has produced thousands of faulty transmissions not offering to correct. I have spoken with multiple transmissions shops and they all know the issues. GM should honor their faulty product either replacing or correcting it. It’s a shame. I didn’t realize what the issue was till it was past the warranty. Upsetting knowing it was messed up from the new sale.

    On July 5, 2024 while traveling and towing our 5th wheel (7,200lbs) with our 2017 GMC 2500 6.0L GAS engine (with the 6L90 transmission) and without any previous warnings or signals the check engine light illuminated and approximately 10 mins later the vehicle went into limp mode with "Transmission Hot.....Idle Engine" warning, causing us to lose power of the vehicle. We coasted over to the side of a 2 lane road with no shoulder and stopped the vehicle to let it cool down. This happened several times leaving us stranded in places that were NOT safe to allow the transmission to cool because we had no other choice since we were on country roads with no pullouts. At this point, we were just trying to get to the closest safest place to disconnect the trailer, so we could have the vehicle looked at by the GMC dealer. The closest place was an RV park approxiamately 20 miles away, so we limped there and disconnected from the trailer. Our safety and the safety of other drivers was a huge issue since there was nowhere we could pull over where we would be out of danger. We had no warning that our transmission was bad up until this point. The dealer inspected the vehicle and confirmed on July 8, 2024, that the vehicles transmission failed and needs to be replaced. We serviced our vehicle religiously and had the transmission flushed/changed at 49,944 miles. The failure of the this transmission occurred at approximately 54,000 miles. We were stuck and without our vehicle for 7 days while we waited for The GMC dealer to replace our transmission. There are plenty of problems with the GMC/Chevrolet 6L90 transmissions and unfortunately, we fell victim to this problem. GMC should be held accountable for issuing a recall as we could have easily caused an accident and serious damage to ourselves as well as others. This transmission is failing causing it to be is unsafe.

    I was in an accident on October 20th 2022 while driving home. U had just reached the top of a sharp crest on a two way road. As I started to straighten out the wheels coming out of the turn I noticed my direction was still as if I was turning the wheel. I tried to brake and pressed the brake but it went to the floor and the truck kept going. I collided with the other vehicle and it was a miracle neither of us were seriously injured or killed. We had problem with the steering box about 2 years ago and had to have it towed to the dealership. The other vehicle was a Chevy 2500 with a custom steel flat bed & it slowed me down and I finally came to a stop with the front tires off the road. Neither vehicle alerted onstar & airbags did not deploy. His vehicle miraculously had minimal damage to the cab the majority of the damage was the metal gear box located under the bed in between the cab & tires. It was super scary & left both vehicles disabled.

    We were at a restaurant with friends we got back into the vehicle. I started up the vehicle and several electrical things happened. The service trailer brakes message came up, then the service power steering message came on. The engine was running but the tachometer didn’t work, or the oil pressure gauge. A couple other warning lights on the dash were on and stayed on. When I put it in reverse it wouldn’t move. When I put it in drive it would move forward. So we were stuck in our parking spot. We decided to put it in neutral and two of us pushed the truck out of the space into a busy street in hopes of getting home. Luckily none of us or the truck was hit by the people driving on the roadway. I put the transmission in drive and it would go into gear but not not shift out of first gear. The speedometer was not working either. We drove a few 100 feet in hopes that it would shift into a higher gear and it would not. We were able to find a safe place to pull off the highway and parked it. Turned the truck off, waited several minutes and tried it again. Still the same so we were stranded there. Left it there and called an Uber driver to come out and pick us all up. I called for a towing service to pick the truck up the next morning. When I arrived the following morning to meet the tow truck I got in and started it up. Other than the check engine light being on the truck seemed fine. I still had it towed to the dealership to be on the safe side. It was there 6 days and today I picked it up. They couldn’t find anything wrong. In the description of service and parts it states “scanned found long list of codes, most of codes are lost communication with engine control module, followed some tsb for possible issues, no results”. Also, “cleared codes and test drove vehicle, have not been able to duplicate concern at this time”. So I now have a vehicle that I can’t trust and hope our safety will not be in jeopardy in the future.

    On December 29, 2022 I stopped at the bank for 2 minute and when I got back to my truck I noticed smoke coming out from under the hood. I immediately called 911 and luckily some nice people were able to get my hood up safely and the bank provided a fire extinguisher before the fire trucks arrived. It was engulfed in flames. The fireman said it appeared the fire started in the wiring at the engine. I had a recall fixed a while back for the engine block heater so I was worried maybe they didn’t repair the recall. A week after the fire I received a 2nd recall in the mail for the same recall. Today is July 9th and my truck is still in the shop waiting on parts that have been on back order this whole time. GMC told my insurance company they were sending someone down to look at it. Never heard anything back. This could have been so bad had I been driving it when the fire started. So here I am going on 7 months without my truck all while paying $942/month. I just want something to be done to speed up the repairs that my insurance has paid. Estimate is $22,000

    The radio in my truck acts on its own (buttons push by themselves). The problem is known and I’m fine with turning my radio off instead of paying a lot of money for a new one. I’ve been fine with it until recently. First problem I’ve let go for a while now which is that it turns on by itself while driving which is a distraction. But biggest problem now is not only did the radio turn on by itself but it also went into the backseat reminder and turned it off. I do have an infant and I hope to never forget. But when paying for a vehicle this is a feature you pay for. No one should lose a child bc of this. I’ve talk to a dealership about the initial problem and have done research on it. There is no warning signs. Vehicle has not been inspected by any others. I do have a video of the backseat reminder turning off without my control.

I HAD ACCELERATED TO PASS A CAR, BUT THE ACCELERATOR WENT TO FULL THROTTLE, AND STUCK ON FULL ACCELERATION. I STAYED IN THE LEFT LANE, APPLIED BRAKES SPORADICALLY TO LIMIT THE INCREASED SPEED, AND QUICKLY HIT THE ACCELERATOR PEDAL WITH MY FOOT AND IMMEDIATELY RELEASED SEVERAL TIMES TO TRY TO "BREAK" THE ACCELERATOR FREE. I DID THIS MULTIPLE TIMES WITH NO RESULTS UNTIL FINALLY, WHEN WE WERE AT 94 MPH, THE ACCELERATOR BROKE FREE, AND DISENGAGED. THE BRAKES SMELLED STRONGLY FROM THE EFFORTS TO RETAIN THE ACCELERATION. THE TRUCK HAD APPROXIMATELY 2,300 MILES ON IT WHEN THIS OCCURRED. I HAD PLANNED TO PUT THE TRUCK IN NEUTRAL AND MOVE OFF THE ROAD BEFORE WE HIT 100 MPH. IF MY HUSBAND HAD BEEN DRIVING, HE MIGHT HAVE TURNED OFF THE CAR AND LOST CONTROL (DUE TO LOSS OF POWER). THIS WAS EXTREMELY TROUBLING, AND EXTREMELY DANGEROUS.

    The pigtails to the injectors are prone to failure. The vehicle without warning throws multiple codes and immediately limits power and speed while shaking. This can cause a dangerous driving situation. This is a known problem and is on many online forums as a common failure. The repair shop gets so many of these that they were able to diagnose the issue over the phone and noted that it usually happens around the 200k mile mark. However many reported this as an issue while under warranty. The issue is with the metal connector material being prone to failure and arcing.

    The def heater gm part#84162464 has broken on my truck. There are many owners with the same problem on their duramax diesels. This has been an issue since def tanks were mandated by the federal government. The replacement cost is estimated to be $2000. from my local dealership. The truck had 50,000 miles on it when the heater first started working intermittently. I'm reporting this so it can be logged in as another incident for failing, poorly engineered parts.

    I was in an accident on October 20th 2022 while driving home. U had just reached the top of a sharp crest on a two way road. As I started to straighten out the wheels coming out of the turn I noticed my direction was still as if I was turning the wheel. I tried to brake and pressed the brake but it went to the floor and the truck kept going. I collided with the other vehicle and it was a miracle neither of us were seriously injured or killed. We had problem with the steering box about 2 years ago and had to have it towed to the dealership. The other vehicle was a Chevy 2500 with a custom steel flat bed & it slowed me down and I finally came to a stop with the front tires off the road. Neither vehicle alerted onstar & airbags did not deploy. His vehicle miraculously had minimal damage to the cab the majority of the damage was the metal gear box located under the bed in between the cab & tires. It was super scary & left both vehicles disabled.
