I was on [XXX] in Athens, Ga. Going about 65mph in the left lane, casually passing a slow truck. it was rainy, in a construction zone, heavy traffic. With no warning lights or indication there was a problem the engine suddenly died and shifted itself into neutral. I had just started going up hill, no left lane median but I managed to barely make the right shoulder, when the vehicle came to a stop it shifted into Park, from that point forward the vehicle was locked down. I was so close to the traffic I had to fold the drivers mirror. I literally sat on the passenger side of the truck with my seat belt fastened because I expected to be hit. Took about 1.5 hours for tow truck. The tow truck driver was nearly hit trying to load the truck, several accidents were narrowly avoided by people trying to move over. Truck taken to Auto Gallery Chevrolet in Commerce GA, after three weeks they confirmed the engine had to be replaced and it would be done under warranty. I have not been told the exact nature of the failure, but they did confirm the engine could not be rotated. They could not tell me how long it would take to find and engine but there was another vehicle with the same issue that was ahead of me. To the best of by knowledge Chevrolet has accepted the failure report completed by the technician but have not otherwise engaged. I have not been provided any documentation from the dealership.

Without any warning driving 65 mph down a freeway the suburbans motor totally shut down. We had to cross over 2 lanes without getting hit by all the traffic. No dashboard lights ever came on until after we got onto the shoulder and sat there for an hour then the check engine light came on. We got stranded 2 hours from our vacation spot in AZ and now we’re stranded 1,600 miles from our home in MN. After 5 hours in the middle of the desert the tow truck finally showed up and towed the vehicle to Sands Dealership in Surprise AZ. We have never had any other problems before this happened. Never thought At 2023 vehicle with 30,000 miles would blow Motor. Waiting to hear from GM on what our options are to get it fixed and get us back home!

I was driving on [XXX] in rural Montana (zero cell phone coverage) on [XXX] (freezing weather, snow packed roads). Without warning the suburban just shut down. It seemed to still have "power". interior lights worked ect. but the engine just died. I tried to pull mostly off of the road but I couldn't get it entirely off of the road because of the snow pushed off of the road by snow plows. I tried to restart the vehicle several times but it would not turn over. I assumed it was an electrical issue at the time. There was zero warning that there was any engine issue. When a mechanic finally had the opportunity to look into the issue he told me the engine has seized up. I had to walk several miles in the cold hoping to get cell phone service to get to a place to warm up. I also couldn't get the vehicle off of the road and I was sure the vehicle was going to be hit or cause an accident on the narrow highway.

Traveling at high speed on major highway and engine stopped. Unable to get car restarted and in fact the instrument panel and information center blanked out. Was forced to have vehicle towed approximately 60 miles to purchasing dealership for diagnosis. Dealer indicates engine is seized and will require replacement. Vehicle has had excellent, verifiable, maintenance record. We have owned this vehicle for approximately 18 months and currently has approximately 62,000 miles. Upon research, I have learned that our vehicle is not the only GM product to have this premature failure.

Automatic Emergency Braking system activated at ~77mph. Essentially I had started braking appropriately and at about the same time the AEB system seemed to conclude more breaking was needed. This led to brief loss of vehicle control when brakes COMPLETELY LOCKED at high rate of speed ~77mph. According to vehicle manual this system should not activate at speed great than 50mph (photo attached). This is dangerous because i could have lost control and/or someone behind me could smash into me. My vehicle does not have adaptive cruise. Vehicle and other systems otherwise work perfectly. As a side note the extreme brake application at high speed caused cargo within the vehicle to slam forward and destroy the windshield, in addition to being a scary event.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
