2022 GMC SIERRA 1500 Complaints

While towing my 7000lb car trailer, I get a message that the trailer brakes need service, then I get another message that the trailer brakes are disabled. At this point the brakes are shut off and no longer work. This is extremely dangerous. The problem is with the truck. It does the same thing with multiple trailers of tried with electric brakes. All of these trailers work fine by my other vehicle with electric brakes for the trailer.

i FEEL IT IS IN THE FUEL MANAGEMENT SYSTEM When driving along every now and then you can feel a vibration like diving on rumble strips. there is no rhyme or reason for it. I had it to the dealer and they told me that was normal, if you don't want it to do it then drive in 9th gear. I'm not going to shift to 9th every time I drive.

The contact owns a 2022 GMC Sierra 1500. The contact stated that after purchasing the vehicle and leaving the local dealer, he heard an abnormal sound with the check engine warning light illuminated. The contact drove the vehicle back to the local dealer, where it was diagnosed with needing the transmission to be replaced. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 170.

Truck was placed in Park on an inclined road. Exiting truck, truck started to roll backwards. I was struck and right foot was run over by Driver's side front tire and knocked down. I was wearing composite toe shoes which enabled me to get up and run after the truck, trying to stop and control the truck a second time. I was hit again and thrown off the side of the road into a briar patch. Truck continued to roll backwards and off the road into the woods. Upon investigation, two separate County Deputy Sheriffs confirmed that the truck. when it came to rest, confirmed the truck was still in the Park position. Truck had to be towed out of a ditch in the woods. I sustained moderate injuries, but thankfully was not catastrophically disabled. This should be investigated thoroughly, so that no other person(s) is injured or dies as a result of this defect.

When I started my truck the Service Power Steering and Service ESC notifications came up on my panel. Now my truck has no power steering and it very difficult to steer and navigate. We are in the middle of a winter storm so it is even more of a safety issue in slippery conditions. The ESC system does not engage either and the truck slides when taking corners much more than it used to before the issue.

I bought the truck to pull a trailer and the truck is equipped with a max tow package. When pulling a trailer after a short distance a warning comes on a says the trailer brakes have been disengaged. I have had it to two GMC dealers and they refer me to a GM PIT5948A. C159C document and is says there is no fix. I bought the truck to tow and it is unsafe to do so.

The contact owns a 2022 GMC Sierra 1500. The contact stated while pulling a trailer and driving 45 MPH, another vehicle entered his lane spontaneously, he depressed the brake pedal; however, the vehicle failed to stop. The contact stated that the “trailer brakes disabled/service required” warning light was illuminated. The contact was able to quickly maneuver to the right to prevent an accident and continued depressing the brake pedal forcefully to stop the vehicle. The contact was able to continue driving to his residence. The contact took the vehicle to the local dealer but was unable to find a fix for the failure. The vehicle was not repaired. The contact stated that he continued to experience the failure. The contact took the vehicle to a second dealer: Scenic Chevrolet Buick GMC (2300 Rockford St, Mt Airy, NC 27030: (336) 429-5457) however, the mechanic was unable to find a repair for the failure. The vehicle was not repaired. The contact stated that he continued to experience the failure. The manufacturer had been informed of the failure. The failure mileage was approximately 1,200.

Electrical component- Dashboard is constantly glitching, blue-tooth will not connect properly, electrical appears to turn off randomly while driving to the point we have to pullover because it appears and feels like the truck is turning off. Power step running boards malfunction- They don't open or close when they are supposed to. Power step running boards also malfunction while driving. It is a risk because we've had to pull over in conditions that aren't safe, putting a family of five in danger. The problem has been reported to the dealership and manufacturer and has gone unresolved.

When I initially started the vehicle, I noticed the parking assist would not turn on. No warning lights or messages were displayed so I didn't think much of it and continued on driving. Approximately 5 miles down the road while traveling around 45 mph, I came upon a stoplight with other cars waiting. I pressed the brake to start decelerating and the pedal went all the way to the floor and vehicle did not slow down/decelerate. The check engine light, ESC, trailer brake, and brakes warning lights/messages then illuminated. I was approaching the vehicle in front of me quickly so, to avoid a rear end collision, I swerved into the shoulder and was able to coast through a right turn and on to a side street where I eventually coasted to a stop. I narrowly missed a major collision and was fortunate that there was no cross traffic approaching when I turned on to the side street. This could have been catastrophic, especially if pedestrians had been in the area. After stopping, I restarted the truck and the brakes seemed to work, however, the warning lights remained illuminated. I drove slowly to the nearest dealership. They replaced the electronic brake control module. Truck has approximately 20,000 miles on it and is well maintained.

While operating the vehicle, the radio went to full volume on its own. Attempts to turn it down did not work. The radio turned down, when the buttons on the steering wheel were pressed, but turned back up faster than I could turn it down. The power button on the radio also didn't work. I tried pushing it and then tried pushing and holding it down for a few seconds. I had to end up grabbing my phone and shutting the Bluetooth off on the phone to get it to stop. Very unsafe and distracting. It has been documented in a forum where others have had the issue as well. It is the new infotainment system and appears to be a software bug. Here is a link to a forum where others have had the same issue. https://www.gm-trucks.com/forums/topic/260308-2022-refreshed-sierra-audio-issue-max-volume/
