I was traveling on the interstate, going a little over 70 MPH as I was passing a tractor and trailer. There were no other vehicles in front of me. Suddenly the truck jerked like the breaks were being applied and my speed was quickly reduced to around 60 MPH. The heads up display showed a crash alert orange symbol. I pushed the gas to try to get back up to speed but the truck would not accelerate and the speed kept dropping. I pulled over to the berm and came to a stop. There was a message on the message center but it went away before I could read it with everything else happening. I put the truck in park and waited a minute then I pulled back out and was able to get the truck back up to speed and home. I plan to contact my dealer tomorrow. The ruck was involved in an accident that damaged the front in earlier this year so I believe some or all of those sensors have been replaced. This is the first issue we’ve had since purchase. If there would have been a vehicle following behind me, the rapid breaking/deceleration could have caused an accident. Also the inability for me to regain my speed when traveling on an interstate was a danger to myself and others.
TWICE in the past month +. On [XXX] my wife and I were on our way to a family wedding and I was driving approx 75 MPH on [XXX]. I don't recall if I had cruise control on or not as I rarely use it. There was no vehicle was in front of me for hundreds of yards yet all of a sudden the vehicle started to brake very hard. I accelerated as I did not know what was going on and I had a car in back of me that started to gain. THEN last Friday ([XXX}) with my wife following me in her car on [XXX] through Ellicott City MD I was traveling at approx 25-30 MPH through a very small historic town when all of a sudden the same [XXX] thing happened. DEF no CC on . When we got to our destination I asked my wife if she saw my brakes come on suddenly?. She replied yes and said she saw the truck dip hard. I told her the brakes did it again. She said I should call the dealer. I did not as they are USELESS! THEN the electronics. On Star has a catalog of my complaints. The radio selections I make just disappear from the screen: Apple Car Play disappears from the touch screen and just goes dark. I have to stop the truck..(per on-star) open the door.. get out.. lock it.. wait 2 minutes.. get back in .. restart the truck, and this re-sets the computers(s). RIDICULOUS! I do not have Sirius but the radio goes dark often for about 2-3 seconds., then comes back on. I was told it is my I-Phone is causing this. [XXX]! What does my phone have to do with AM/FM radio?? I was told by GMC there is a patch to update the software. Koons GMC told me there was no such patch nor recall. I paid nearly $80,000 for this piece of [XXX]!

1st time Complete failure on my 2024 engine without warning. As I was traveling on the interstate. All of sudden, I lost all power. Mt truck started slowing down on its own. It was very difficult getting out of the way of on coming traffic. Dealership replaced values. 2 months later. Again on the Interstate engine complete failure again. Now take it to dealership. This time I heard a ticking noise. Right after the ticking noise. Engine stop working. Same situation. Trying to get out of the way of traffic. I was stranded over 3 hours.

On December 26th 2024, I was travelling 5 mph or less while pulling into a parking space at a restaurant. As I let the steering wheel return to center, my hand hit the Resume button on the left side of the steering wheel and the vehicle immediately began to accelerate. I was able to step on the brake to prevent the vehicle from hitting the wall of the restaurant. The next day on December 27th, 2024, i was able to duplicate the problem. I had set the cruise at 55 mph before I came to a stop at a traffic light. I released the brake and pressed the Resume button and the vehicle immediately accelerated from a dead stop. I've been an automotive mechanic for over 30 years and I've never seen this happen before. It's my understanding that vehicles wouldn't engage cruise control unless the speed was over 35 mph.
Truck thinks I’m about to run into something and slams on its brakes. Last time it sent my sister to the hospital to get 6 staples in her head. Digital cluster goes on and off as well as the infotainment center. Transmission bangs and shifts horribly. 900 miles on the truck with a check engine light and transmission warning.
10/9/24: All interior vehicle sounds (turn signals, hazard lights, parking warnings, collision warnings, etc.) along with the audio sound system, are audible in my vehicle via the vehicles’s audio system speakers. For reasons unknown and without warning, all interior vehicle sounds and the audio sound system cease to make audible sound; however, the infotainment display screen and the instrument cluster screen continue displaying normally and appear to function properly (system still accepts touch screen inputs and visibly displays volume knob input adjustments). So, in summary, a disconnect occurs between the infotainment system / vehicle audible warnings and the vehicle’s speakers, through which the sounds emitted. We purchased our 2024 GMC Sierra 1500 AT4 as a brand-new purchase on 9/30/24 and it is completely stock, with no post-purchase or aftermarket alterations having been made to the vehicle. This issue has occurred on two separate occasions since the purchase date, with the occurrences happening on 10/8/24, and once on 10/9/24. When this sound-disconnect issue occurs, it will last indefinitely until we remedy the issue. The only remedy for this issue that has worked thus far requires that we completely shut the vehicle down, wait a few minutes, and then restart the vehicle. In researching this issue, I have found multiple comments over various forums by various users who have reported dealing with this same issue.

Extremely poor rear camera quality at night. Common complaint on GMC and Chevy 2023/2024 models. Unsafe to reverse at night due to poor camera image quality. Cadillac has already issued a recall on their units which are identical to the GMC and Chevy. Many posts on Facebook gmc at4 and Chevy zr2 owners groups about the safety issue
