Engine & cooling
On January 1st driving east bound on road 520 in central florida. I was driving around 65mph when the vehicle suddenly shut off. The displayed showed a warning saying that something of the sort that I needed to press the brake to start the engine even though I was driving normally. I had to coast to the side of the road and I pressed the brake. once the brake was engaged the vehicle immediately went to park and will not start. I press the ingition button and the screen would go blank and no sound or warnings were displayed. I had to call the police to provide a safety as the vehicle was in a very dangerous area and all my family was on the vehicle. the police laid down flares and I contacted a tow truck using onstar. Onstar was unable to communicate with the vehicle to diagnosed the issue and no warnings or errors were displaying. …
When traveling at highway speeds our vehicle suddenly lost all engine power. Driving in the passing lane of [redacted] at 75 mph our 2023 Chevrolet suburban RST 6.2 lost all engine power and went into neutral. We were barely able to make it over to the right breakdown lane without getting hit and making it with no power. We were stranded on the busy interstate for three hours with my wife and three young kids in a very dangerous location. They were scared and because we barely made it into the breakdown lane and so close to speeding traffic had to stand outside of the vehicle close to the woods further from dangerous traffic. The Suburban was flatbedded to nearest Chevrolet dealer where we were told the engine was seized and would need to be totally replaced. We were lucky to be alive but now stranded 1000 miles away from home as we were returning from a vacation in Florida. …
Transmission & drivetrain
While driving our 2023 Chevrolet Duramax diesel suburban, I was waiting, at a complete stop, against the median to make a U turn. When the traffic cleared, I began the turn when I suddenly noticed a nearly complete loss of power, hesitancy of engine engagement, and little response to the gas pedal being depressed. Then an error message appeared on the dashboard stating "Low acceleration warning". There was very little acceleration power available. The rear wheels seemed to spin. I was perilously endangered while making a U-turn across lanes because of this loss of power. The vehicle was then taken immediately to our local Chevrolet dealer who diagnosed a error code message (P0700, 0747) related to transmission valve and injectors. We are very concerned that this was a dangerous occurrence and should be further investigated. …

Electrical system
I recently took my 2023 Chevrolet Suburban in to make sure everything was working properly with the power train... it has been having bucking and stuttering between 15-45mph, which was super concerning to me, as I am transporting 3 children [redacted]. I took in yesterday, and was called back today to confirm that the issue is happening... the problem is that instead of Chevrolet recalling these vehicles to have this computer issue taken care of... they did an update and are charging their clients to have this update done. This is a serious safety hazard, especially for families like mine that cannot afford to have this update done. I will likely have to drive around without having it done, all because of GM's greediness.
The windows would go down all by themselves and not roll up . The infotainment system will flash on and off telling you to start strip all by itself. The door locks will lock you out and in not letting unlock the truck . The key fob is the only way to unlock it. I have taken it to the dealer five times to be repaired and they say GM software is not capable of finding the electrical problem. They just keep replacing parts. I filed a complaint with The State AG office and GM said they were not going to address the complaint because the vehicle was still under warranty.
