2017 GMC Sierra 2500 Problems

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.

Service Trailer Brake warning comes on repeatedly. Trailer brakes fail to work.

The ABS light came on while driving. Tire and components were removed to expose the axle housing. 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.

The contact owns a 2017 GMC Sierra 2500. The contact stated that while his wife was driving at an undisclosed speed, the vehicle experienced a loss of power steering assist, and the brakes failed to stop the vehicle immediately. No warning light was illuminated. The vehicle coasted to the side of the road. When the contact arrived on the scene, he noticed that the generator pulley had detached. The contact then purchased a new generator, which he replaced himself. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was 55,756.

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.

When connect my trailer i get a service trailer brake system, then the stability waring start to show up and the brakes on the vehicle seem to act funny. Very unsafe while towing a trailer and kids in the truck. VERY UNSAFE

Break lights activate by them selves. Can be driving, parked, vehicle off. Parked and locked. The break lights activate randomly. Most recently car was parked in drivevway over the coarse of 2 days. Break lights came on and off until batteries were dead. When parked I Can hear clicking noise coming from under the hood periodically, not sure if related or not. Also noticed cruise control will shut its self off some times.

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.

HAD MAJOR HEAD ON COLLISION AND THE AIR BAGS DID NOT DEPLOY

TOOK TRUCK IN FOR FIRST OIL CHANGE.I HAD SEVERAL PROBLEMS INCLUDING THE BACK TIRES BEING OVER 50% WORN OUT. ALIGNMENT WAS OFF AND DEALER REPAIRED THAT AND ROTATED THE TIRES. NOW WHEN I STOP AT ABOUT 5 MPH THE TRUCK JUMPS. I REMOVED THE ABS FUSE AND PROBLEM GOES AWAY. DEALER STATES THERE IS NO WARRANTY ON TIRES EVEN IF THEY WEAR OUT IN 6000 MILES AND THE PROBLEM WAS THE VEHICLE WASN'T PUT TOGETHER PROPERLY THE FIRST TIME.IF THE ROADS WERE COVERED WITH SNOW I WOULD BE IN REAL TROUBLE.NORMAL HIGHWAY TRAVEL AROUND TOWN

NATURE OF CONCERN: WHEN THE VEHICLE IS PUT INTO REVERSE, THE REAR BACK-UP CAMERA COMES ON. THE DISPLAY OF THE CAMERA IS EXTREMELY TOO BRIGHT, AND MAKES IT DIFFICULT TO BACK UP PROPERLY WITH A GLARING LIGHT IN YOUR FACE. THERE IS CURRENTLY NOT AN OPTION TO DECREASE THE BRIGHTNESS OF THE CAMERA.
