2022 GMC SIERRA 2500

Was driving down the highway and was approaching a red light. As I was slowing down my transmission down shifted hard and my rear wheels briefly locked up and my truck went in to reduced power Took to dealership only to find out the valve body failed and my truck wasn't covered

The contact owns a 2022 GMC Sierra 2500. The contact stated that the engine was making an abnormal rattling sound on cold starts. There was no warning light illuminated. The vehicle was taken to the dealer, where the front muffler exhaust baffle was replaced; however, the failure persisted. The vehicle was taken back to the dealer, where the contact was informed that the rattling sound could not be heard; however, the contact stated that the rattling sound had become louder, and other individuals were able to hear the rattling sound. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Odometer Fraud. The contact purchased a 2022 GMC Sierra 2500. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 92,000, and at the time of registration, it was discovered that the mileage was 98,325. The Carfax report was not available at the time of purchase. The mileage discrepancy was later identified through the vehicle manufacturer’s Mobile App.

I had taken our GMC Sierra 2500 with LT275/R20 Goodyear Wrangler tires into Henderson Chevrolet for maintenance and to have the tires checked. The technician stated that the front tires were showing tread separation. I was shocked because the tires only had around 20,000 miles. The truck is not used for towing and is kept in the garage away from the sun. I asked the technician to double check the rear tires for separation and he stated they were fine. A couple of weeks later, I was driving to California and there was a loud bang on the rear driver side. The truck indicated the the tire was losing pressure. I pulled over to the side of the busy road as soon as possible. The entire tread was missing form the tire and when it came off it damaged the wheel well and the rear bumper and taillight.There was a lot of traffic on the highway and not much shoulder it was a pretty scary and unsafe situation I but got the tire changed with the spare. About an hour later the passenger side tire blew up, there was way more damage on this side including bent exhaust and damage to the fender. I had to get roadside assistance to change the tire so I changed both rear tires so i could have a spare.When I took the car back to Henderson Chevrolet they told me this is a common problem they have had 10 in the last 6 months. Boulder Autobody said they had seen 7 in the last 6 months. Henderson Chevrolet sent both tires to Goodyear to be examined and they conveniently lost one of them and stated that the tires were not defective. Thank goodness no one was hurt, this could have easily killed someone.

After driving my truck, once I park and turn the truck off it will not shut down electronically due to an error on the dash display that reads “shift to park”. Sometimes I have to mess with the gear shifter when the truck is in park to get it to register that it is parked and shut down completely. It can take up to 15 minutes sometimes to shut down.

I am receiving a "Shift to Park" warning intermittently when parking my truck. The truck is in park, but the transmission does not recognize this and flashes the warning on the dash and chimes. While this is happening, I cannot lock the vehicle, and the battery is being drained. I have read that this is a known issue with other GMC models as well. I just was given a $1074 bill to replace the transmission control with park sensor.

After placing the vehicle in park and try to turn it off, I receive a message saying “Shift to Park”. The engine is off and in park, but the vehicle doesn’t recognize it as being in park so all of the electrical stays on. I started complaining about this to the dealerships before my warranty was up but they kept giving me the run around avoiding the fix and now that the warranty is expired they want to help me for a ridiculous fee. This issue happens randomly at least one day a week.

I was driving my 2022 GMC 2500 HD (not towing, just normal drive) after an oil change <900 miles ago and new brakes/rotors 3 days prior <100 miles (total mileage 81,000, serviced exclusively at GMC dealership) when the loss of power alert flashed on the screen. I was 2 miles from my destination, going approx 55mph, so I kept driving to destination, when the vehicle stalled in driveway. As I was scrolling through menus to see the alert I looked up and smoke and flames were coming out of the engine. I attempted to extinguish with a fire extinguisher I had with me, but it was no use. The entire engine was engulfed, melting out, tires and windshield exploded from heat etc. Total loss. Vehicle was inspected by insurance co fire investigator, no origin confirmed due to extent of damage. Vehicle was offered to GMC for their inspection as it was partially under OEM warranty and I had an extended warranty from dealership, which I also notified. Extended would not do anything without the vehicle at GMC and diagnosis, which again, there is no engine etc so not repairable. GMC was to be in contact with insurance co. No status update received.

My booster is leaking into the floor. I took it to the dealer and they said it was the booster and it needs to be replaced. This could make the truck lose its brakes and run into something or someone.

The recall has been performed over a year ago. The dealership failed to update their records, our company continues to receive notices that we need to have this recall completed.

I was driving home from work and my truck down shifted and rear wheels locked up, now it’s in limp in mode and will not shift.

The contact owns a 2022 GMC Sierra 2500. The contact stated while her husband was driving approximately 75-80 MPH, and the contact was in the front passenger's side seat, the vehicle lost motive power, and the infotainment system and instrument panel turned off unexpectedly. The contact's husband pressed the PUSH to START button, and the vehicle was able to be restarted. There was no warning light illuminated.

After taking my truck in for recall fixes. I received a message on my screen saying that I had 94 miles until I was limited to 65 mph. It said check DEF system. After taking it in the dealership charged me to fix the computer. Known defect yet they charge for it.

The gmc trailering app will not read trailer tire pressure above 100psi. When trailer tires carry a safe psi amount above 100psi the trailering app will not be able to confirm if the trailer tire is low in pressure which could cause a massive wreck if driver did not know the trailer tire was going bad. Truck was taken to dealer, they tried to follow bulletin 22-NA-172 to have the pressure to read above 100psi. But they could not get it to work, I was told it was a trailering app issue and nothing they can do until GM takes the steps to fix the trailering app.

Trailering a trailer with electric brakes. The vehicle intermittently reports connection issues where the brakes are temporarily disabled however the trailer lights are not effected. This leads to a period of time where there are no brakes on the trailer. Pretty confident we have eliminated the trailer as causing the issue.

The vehicle will be in the park position and a warning on the dash will say shift to park not allowing you to shut off the vehicle. Jiggling the shifter sometimes works but often have to restart the vehicle numerous times to get the error message to not appear and be able to proceed with shutting off the vehicle

Concerning Goodyear Wrangler Trailrunner AT P275/65/20 tires that came stock with my 2022 GMC Sierra 2500HD, which currently has 42,000 miles on it. While driving a round trip of no more than 30 miles the evening of 11/29/24, I noticed a slight repetative jaring motion, which I initially attributed to a potential transmission issue. The bump rapidly worsened halfway though the drive. Upon inspection at the time, I could not see any visible damage to the tire. However, the issue escalated aggressively during my return home, resulting in the tire blowing out and detreading entirely. This failure caused significant damage to the body of my truck, amounting to an estimated $3,500 in repair costs. I believe this incident is due to a defect in the tire, as such occurrences are highly uncommon and unexpected from a product of your reputation. I have oil changes as recommended by the trucks service maunual and with ample tread left on the tire and good scores of inspection it begs the question on how a tire could fail so abruptly. I have 3 other tires with ample tread which should last at least another 10k miles but I'm gravely concerned with continued use of them for fear another blowout could cause a fatal accident.

The contact owns a 2022 GMC Sierra 2500. The contact stated that while driving approximately 65 MPH, the warning message "transmission overheated" had suddenly displayed and an audible alarm activated. The vehicle was later towed to the local dealer who diagnosed that the transmission valve body assembly needed to be replaced. The transmission valve body assembly was replaced and the failure was remedied. The manufacturer was notified of the failure. The failure mileage was 18,334.

AC will not run while truck is in idle. I was told by the dealer all GM trucks with the 6.6 gasoline engine this is a standard on them. this is a major safety issue when it becomes 100 F outside.

Hello, I purchased a 2022 GMC Sierra AT4 2500 in August of 2022. I then purchased a 2022 Alliance Avenue 30RLS in September of 2022. The first time we took the Alliance Avenue out on a camping trip (October 2022), we had brake controller issues. The brake controller would suddenly disconnect and I would have an error on the screen saying that the controller was no longer connected, and the light would go off on the brake controller on the dashboard. At this point, we had no trailer brakes. This issue happened several times, and the controller would go offline and come back, sometimes within seconds, sometimes in minutes (up to 10+). Strangely, the lights and signals continued to work. After the trip, I brought the trailer back to our RV dealership where they inspected the brakes and said we were okay on that end. I then took the truck to a GMC Dealership who informed me that everything was good on their end... Next trip, same issue. Took the trailer to the RV dealership and they took the system down to the brake pads and said they didn't see anything, but they rerouted some brake wiring just in case. On the way home from the RV dealership, the brake controller continued to fail. Took the truck back to GMC, they found nothing. Had a 3rd party RV repair tech install a solar shutoff switch and replace the trailer side brake plug in pigtail to rule that out. The issue persisted. Took the truck to a Chevy Dealership, the found no issues. Took the trailer camping several times, same issue persisted, and we were in dangerous situations over the Colorado Mountains, having this fail multiple times over Eisenhower Pass and other mountain passes. Took the trailer back to the RV Dealership, they found nothing - took it to the Chevy Dealership, they replaced the truck bed plug-in. The issue persisted. The Chevy Dealership informed me there was a module replacement for the GMC 2500 2023-2024 trucks, but they could not do that for me.

GOODYEAR WRANGLER LT275/65R20 LOAD E TREAD ON PASSENGER REAR TIRE PEELED OFF AND CAUSED DAMAGE TO VEHICLE AND THE TRAVEL TRAILER BEING TOWED.

[XXX]: After arriving home and parking in my driveway (plugged in the block heater that came installed from the factory), approximately 35 minutes later my neighbor rang the doorbell. She was yelling that my truck was on fire! The flames were starting to hit my eaves on my house. I put the fire out with my hose. The Sparks Fire Department had to pry open my hood to disconnect the batteries in order to stop the truck from lighting back on fire. The vehicle has been inspected by General Motors and turned over to their insurance. My insurance has also inspected the vehicle and stated they believe that the wiring to the block heater was faulty. There were no warning lamps, messages or other symptoms of the problem. This truck has 19,000 miles and is 1.5 years old (2022). How could this be turned over to GM's insurance and not under warranty? I have not had my truck for over 2 months now. I wonder how many of these trucks are lighting on fire? The truck is currently at the local dealership and is available for inspection.

Trailer brake controller that is built into the truck intermittently works when towing a trailer. I will be towing down the road and all of a sudden I will get a warning on my gauge display that says “check trailer wiring” and the light that indicates that the trailer brakes are working goes out. Meanwhile, all of the lights on the trailer still work. After about one second, another message appears and says “trailer brakes connected” and the light on the brake controller comes back on. When this happens, the larger screen sometimes has a message that says “trailer brake gain recalled” but sometimes it says “brake gain not recalled”. When the message “check trailer wiring” comes on, the trailer brakes don’t work. The trailer brakes start working again when the message “trailer brakes connected” comes back on. You can feel this in the truck, especially when it goes off, on, off, on, etc while you are trying to slow down. You literally feel the truck surging as the brakes are intermittently being applied. I have taken the truck to a GMC dealership and they were not able to duplicate the issues since the issue only happens when the truck is hooked up to a trailer that has trailer brakes. I had a certified RV mechanic inspect the trailer brakes and they are working like they should. I hooked the same trailer up to a Ford F-250 and had zero issues. I hooked the same trailer back up to my GMC and immediately had the same issues. I am taking the truck and trailer to a different GMC dealership on March 11th to see if they can duplicate this and diagnose the problem. I called GM corporate customer service and they were basically no help. This is a big safety issue because the truck is not telling the trailer’s brakes to function like they are designed, which makes it much more difficult to slow down, especially going down hill. I have done a bunch of research on this problem and found numerous online forums on this topic, so I know I am not the only one experiencing this

The engine failed. The 2022 GMC Denali had 12,000 miles on it. This was a brand new truck. We were driving home at night the engine began to make noise and then cut off in the middle of the road. We had to get the car towed. The truck was left on the side of the road on a very busy highway. The dealer confirmed the engine failed and found metal shavings in the engine. The dealer has recommended a new engine from the GMC Manufacturer. The manufacturer has not yet responded to the dealerships request. The engine light did come on prior to the engine shutting off.

The headlight was flickering. For a week before it burnt out completely. A flickering headlight causes a distraction to other drivers. Not to mention a LED light shouldn’t burn out in one year.
