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.

I was driving the vehicle at approximately 45 mph when the vehicle suddenly had no engine power. There were no warning signals or symptoms of an issue that would indicate there was a problem, but the dashboard told me the vehicle needed a restart. I was able to pull the vehicle out of traffic at a cross street and coast to a stop in a parking lot. Had I not been where I was at the moment when the engine failed, or had there been oncoming traffic that would have required me to stop coasting, I would not have been able to pull safely out of traffic. The vehicle was towed to the dealer where it was purchased. They told me the next day that is was an internal engine failure.

On April 7th 2024 we were traveling on vacation 2 1/2 hours from home and our vehicle started making a ticking noise and traction control, engine light, service emissions, and front collision warning all came on. It was idling very rough. We had to stop for the night with our kids and take it to the closest dealer the next morning. They diagnosed the car and confirmed that the lifters needed repair. We had to leave our vehicle and get a rental to make it back home. The dealer made repairs and sent vehicle back to us. Fast forward to 1/15/25 I was on the way to work and the same thing started happening. I then had to tow the vehicle to the dealership and they have diagnosed it with the same issue on the other side of the engine. As a brand new vehicle this should not be happening. Each time we were stranded with kids and without a vehicle for a long period of time.

Engine died without warning on interstate. Vehicle was towed to Chevrolet dealer where defective rod bearings were found. Engine was replaced by dealer.

While driving my family home from our christmas vacation on the Garden State Parkway (NJ) the engine shut off and would not restart. This happened on a stretch of the highway with no shoulder while traveling at 65mph. Thankfully we were able to coast far enough to a section of highway with a shoulder. This incident left my [XXX] , [XXX] , my wife and I and our dog stranded in the freezing cold 100 miles from home. After a stressful next few days the Chevrolet dealership diagnosed it as blown bearings in the motor. It has now been over three weeks and no word from GM when a new motor will be available.

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.

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. The vehicle was towed to Carl Black Chevrolet of Orlando Florida. The dealer stated that the engine is locked (L87) and was not able to turn, therefore the vehicle does not start. The dealership technicians have informed that the vehicle needs a new engine and GM needs to approved, the vehicle is still under warranty and I've contact GM and until today, 17 days later, GM has not responded or allowed the dealership to fix my vehicle.

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.

The 2023 Chevy Suburban has a serious oil burning problem. It starts burning oil after 20,000 miles. It starts burning oil after 50,000 miles. Many people around me have this problem. Why is there no recall?

While driving on interstate, vehicle's engine turned off and transmission switched to neutral without warning. Vehicle was stopped and immobilized with no ability to shift or start.

Failed break fluid detection

The fitting on the fuel pressure regulator on the engine began to separate from the housing and started spraying fuel all over the firewall and the fuel ran down the firewall onto the exhaust pipes. No check engine light signaled. The only way I knew that it was spraying, was I started to smell raw fuel through the air conditioning vents. Luckily I was able to get it to a dealer before any fuel caught fire. The dealer repaired it but GM stuck me with half of the bill for the repair. I have pictures of the failed part if necessary. This is extremely dangerous to anyone that may not pay attention to car issues unless a check engine light comes on.

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.

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.

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 [XXX]. 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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
