Wife is RN at a trauma hospital going to work in the morning on a busy highway. While in front of Hospital truck started to indicate to hit starter button. Truck was already running! Wife stopped at red light. Truck stopped running would not start. Stuck in middle of morning rush hour traffic had to have truck towed to dealership. At the dealership they indicated they found metal parts in the oil pan. They indicated a further look into the engine indicated it was beyond repair and had to be replaced. Truck only had 42k miles on it. They stated they had another one same situation in the shop as well and that it would take several weeks to repair. I have learned that this is a major problem with this make and model and engine. Engine quit with no warning in middle of major highway. Thank god not in an intersection or freeway.

When traveling at highway speeds our vehicle suddenly lost all engine power. Driving in the passing lane of [XXX] 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. The sudden lose of all engine power traveling on the highway with our entire family was both scary and dangerous. The suburban has now been in the shop for three weeks with no date in sight to be ready and 1000 miles away. This was a truly dangerous situation and thankfully we came out unscathed but I fear someone else may experience the same type of failure and not be so lucky.

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. We have a 30-year history of Suburban ownership, however this is our first diesel model. We have never had problems of this significance, or seen this error message before. Since this diesel Suburban is nearly new, we are particularly concerned about the durability and safety of this vehicle. Please see attached servive report. The AC compressor was also failed and replaced

DEF sensor has failed and required placement. Required three visits to the dealer to get them to address it (Grayling, MI, White Lake, MI and Charlottesville VA). Transmission throttle body failed and required replacement. Took 2 visits to get it addressed.

1/10/25 Complete braking system failure, could no brake, could not use emergency brake.

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.

Failed break fluid detection

The wipers have stopped working on a least 6 different occasions. I have to pull over immediately due to not being able to see out the windshield. I try adjusting the switch through all the settings. I shut off the engine and restart the truck. I also turned off the rain sense function on the vehicle settings. Nothing I do will get the wipers working again. I have to wait for the rain to slow down to try to get to my destination. While I continue to drive, the wipers will start working again after about 15 or 20 minutes. The first time this occurred, they were only out for around 30 seconds before they started working again. It seems each occurrence is taking longer for the wipers to come back on. I took the vehicle to Armen Chevrolet of Ardmore on 08/05/2024 for service. They were not able to duplicate the problem. I was told to bring the truck back while the wipers are not working. That is a problem since this only happens intermittently. I fear for my safety and others if this happens at high speeds on a highway in heavy rain. I have another appointment on Monday 09/16/2024 to have diagnose the problem again.
