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.

Ok my issues is the same recall on many other 2017 gmc 2500HD but not my VIN. Recall number N172120230 (rear wheel hub but loose). In my situation I was driving at low speed went to stop and abs light came on from oil on my rotator, I also heard a knock from the rear wheel. I pulled over and looked under the truck to find my axel seal leaking fluid all over my tire and breaks. I looked into the Facebook form on this problem and found many people with the same issue. Had the truck towed to the dealer where the are refusing to repair and not coving under warranty for 1-€ bigger tires. My truck only has 39,000 miles and a axel seal should not be going out, and if so should be covered

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

My 2017 GMC 2500 Sierra denali duramax has had this throttle issue, it seems to only do it when the exhaust stinks, and at speeds between 5 - 55 mph. If I take my foot off the accelerator the truck maintains RPM (1200 - 1400) or even has increased some and has lasted 2 - 5 seconds (estimated and greatly reduces the effectiveness of the braking capacity and responsiveness/stopping distance). Worst was with a huge trailer behind and I got up to speed 55 on county hwy 8, and I let off the accelerator and it kept going hard and I got on the brakes and I couldn't slow it down until the truck decided to release off the throttle.(two witnesses in the vehicle, one a GM tech, stating your vehicle is not safe and needs to be looked at) it's happened about 25 times in 5700 miles in various settings & speeds and has occurred frequently in town at speeds of 25 - 35 mph. There maybe several hundred miles in between episodes if you will, as they occur in clusters when exhaust stinks and gone when exhaust does not stink. Truck also had torque converter not unlock and [xxx] near choked the engine off at stop sign right after a throttle stuck condition. Got home the other night and fuel gauge stopped working! back up camera is daylight bright at night, low coolant issues, map sensor issue, engine surged the other day, what next" it's constantly been at dealerships with no answers. My wife won't drive it anymore and wishes I wouldn't either fearing it will cause an accident and she's probably right.
