The tailgate is opening on it's own. There have been many times it has been open and we were not aware until we go to the back of the truck or put the truck in reverse and notice it on the backup camera. We first noticed it happen around Christmas of 2023, and it has been happening randomly since then.

While driving vehicle with infotainment system playing radio, radio volume goes to full volume that is ear piercing and is going to cause hearing damage. Must pull off the road as fast as possible, place vehicle in park, shut off vehicle and open drivers side door to get radio to shut off. While the issue is happening volume knob does nothing, stereo on off button does nothing and steering wheel volume controls do nothing. This is a serious issue when trying to pull over, I keep ear muffs in vehicle to protect ear drums. This has happened at least 6 times, I plan on bring to GMC dealer.

While driving, on its own, the radio volume surged to 100%. All radio controls were unresponsive, and the volume was maxed-out.. Volume bar on the console display was reading 100%. Was unable to turn the radio down or off. Issue did not resolve until I drove home and turned the vehicle off.

While driving the vehicle, the volume on the audio panel shot up to 100%. It caught me off guard and nearly caused me to steer into oncoming traffic. All volume knobs and switches were unresponsive including the power button to the whole unit. I had to pull over and shut off the truck and let it sit for over 10 minutes in order to get it to stop. There are now numerous audio issues, including but not limited to the audio speakers making a crackling noise so bad it renders the use of any audio completely, also periodically the audio loses all volume and will remain completely silent regardless in AM/FM, Satellite Radio, bluetooth or phone call. All these seem to happen anytime the truck gets wet from either car wash or the weather.

While driving the vehicle, the radio will suddenly and instantly jump to full volume frightening the driver and passengers and making it hard to focus on the road and control the vehicle. The dealership and GM will not fix the issue as it happens intermittently.

Unwanted Radio Volume Ramp Up to Max: The radio volume turned up to the maximum while driving and could not be turned down with user controls including those both on the steering wheel and the volume knob on the dash. The situation lasted about 60 seconds before it began responding again. The vehicle has the optional Bose radio system which is EXTREMELY loud. This issue presents risks with damage to my small daughter's ears, as well a significant distraction from driving due to frantic attempts to decrease the volume while being overwhelmed by the noise level.

- Daphne, AL, USA

The vehicle is brand new with only 300 miles on the clock. Today while driving to work and listening to XM-radio the volume spiked to max and would not respond to controls to lower volume or turn off. I was able to lower by switching to a different output. It was very detracting and potentially dangerous since the Bose speakers are very loud.

- Durham, NC, USA

On multiple occasions the Radio has went to max volume for approximately 2-3 seconds then shuts off and goes through a reset. This situation can cause the driver to be suddenly distracted put the driver and others at risk of an accident.

I bought a new GMC, I received 3 vouchers for computer chips to be installed at a later time years ago. They have not provided them. They are selling new fully equipped vehicles with computers chips just fine. Can you handle and have GMC install their backlog of computer chips? There are many safety features that DO NOT work, like parking assit and basically all warnings like when backing up etc. They made me sign a form stating they are not responsible for safety issues stemming from this (our inability to sue) this should be illegal. Thanks.

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.

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.

On 05/28/2022 my family was driving my brand new 2022 GMC Sierra 1500 3.0 Diesel at a rate of 60mph. There was suddenly a loud clunk (transmission) after proceeding a little further and getting speed back to 60mph there was a similar -??clunk-??-?? the diesel truck then immediately gained several various check engine / sensor lights all over the dash and went into Limp Mode. Speed slowly decreased from 60mph and finally as we were navigating our final left turn to our destination the truck would not accelerate thru an intersection subjecting our entire family to utter danger of oncoming vehicles. As a last ditch effort to save ourselves I put the truck in reverse and was able to reverse about 2mph. Then proceeded to shut the truck down and turn it back on to get out of the intersection, but the truck would not come out of park. Onstar emergency was contacted to call the police as we were in an extremely dangerous situation. This truck nearly caused our entire family to get in a very bad collision. The truck was stuck in the middle of the intersection for over 2 hours. The police even attempted to help getting the truck out of park, but was unsuccessful. The truck was scanned on site and had various codes including C1555 (x4) U0101 (x2) P25A2 U220F Collision assist light Check engine light Service Traction Control Light Service ESC The truck experienced catastrophic failure at only 319 miles. Day 4 of ownership. This vehicle needs to be investigated if it is failing this early on. There also needs to be a manual release for the parking gear. Truck has no way to be placed in neutral upon failure of the transmission relay.

Check engine light came on at 458 miles. Took it in and after an hour they determined it was the ecm. They said it was bad. Now they're on the hunt for one. In the meantime, in a day the truck has started feeling like it's over shifting and then bogging down. 458 miles, really! I'm going to need a loaner for longer than I've had it and still make payments.
