I had a engine failure in my 2024 Chevy Silverrado Trail Boss1500. I had just exited off the highway and came to a complete stop at the stoplight. When the light turned green, I hit the gas pedal and I did not move. I looked down at my gear shifter and noticed the truck was in park (I did not shift the truck into park). I tried to put the truck into drive and realized the engine was not running. I tried starting the truck and it would not start. The truck would crank, but would not start up. I tried this several times with no luck getting truck started. I even tried to put the truck in neutral to get the truck out of the middle of the road and could not get it neutral to move it. I called chevy roadside to tow it to the dealer. The dealership called me on tuesday and said the engine had blown because of a bearing failure and engine needs replaced. Also, they have not let me know approx time I will get my truck back. They claim there's a shortages of engines on the 6.2 liter engine.

While driving my vehicle on the highway I was exiting when I looked down at the instrument panel it stated a message along the lines of shifting to neutral and to press the ignition to restart engine. I noticed the vehicle wasn’t accelerating when attempting so I slowed down and did what it instructed me to do. The engine then wouldn’t start, I was uneasy because cars were coming from behind at a decent speed because of morning traffic. I somehow managed to get it to crank and took it to the dealer right away. They stated it was from low voltage and were replacing the battery under warranty. I didn’t think that was the cause but gave them the benefit of the doubt. 2 weeks later while taking my family out, the same incident happened. I wasn’t able to get it to crank and had to get it towed to the dealer. They stated it was the engine because now the engine was making a loud sound when ignited. It is about to be 4 weeks without vehicle and no repair has been made due to no inventory on engines.

Was pulling out onto the road from sitting at a traffic light, vehicle was going less than 25mph when the engine made a clunk trying to shift and the check engine light came on. Computer software indicated “limp mode with reduced acceleration activated.” Vehicle wouldn’t accelerate above 35mph, had to drive on major highway to get to dealership. Truck is only used as commuter vehicle hasn’t towed anything. Dealership indicated valve body transmission failed with vehicle only have 9k miles on it. Part is on back order as it is being manufactured due to installed faulty part, problem has been going on in 2023/2024 Chevy and gmc trucks since January 2024 without a recall put in place. Problem is being fixed after the part fails and the truck fails to run at optimal valves. According to forums software update were installed versus recalls to the actually valve body part being. I was sold a truck in sept 2024 with a faulty installed part versus it being fixed before it was purchased. This caused me to be stranded 1500 miles away from my home and we were not made aware of the know valve body transmission issue. The information was covered up versus being disclosed.

Experienced sudden engine failure while driving on the interstate. Mileage on the vehicle is 11,635. Engine has been maintained as per manufacturers recommendations. Currently at dealership awaiting engine replacement. Was informed that main locking cap for crankshaft came apart, resulting in a hole in the engine block with sudden loss of oil and oil pressure. Currently replacement engines are not available as GM has had a large number of 6.2 L engines that have similarly failed. Dealer cannot provide information on when replacement will be available.

On [XXX] at [XXX] while driving at highway speeds (70-75 mph) on [XXX] , I experienced engine failure in my 2024 chevy silerado zr2. Within seconds, the truck began to lose engine power, the check engine light came on, a transmission warning displayed, the truck shook violently and lost electrical power and power steering. I was able to get to the shoulder in less than a minute and the truck shut down completely. After exiting the truck, I observed smoke, the smell of fire and engine oil/ fluids all over the ground. There were no warning lights or symptoms prior to the engine failing. The sudden loss of power and power steering could have resulted in an accident. The vehicle has been inspected by a certified chevy dealer and they have verbally confirmed engine failure. i have not been provided any documentation or formal updates on the process.

My name is [XXX] and I currently own a 2024 Chevy Silverado 1500 ZR2 Truck with a 6.2 lt motor. On [XXX], my truck failed me at which point it had to be towed by road side assistance to Sun Chevy in Chittenango NY. While at the dealer I was advised that my Truck engine 6.2 is bad that the crank shaft bearing failed and further piston rods failed and it would need to be replaced. Two days following I received a call and was advised by the dealer (Sun Chevy) that GM advised the dealer to rebuild the engine. Once that was completed 10 days later the dealer contacted me and stated that the motor does not sound right and there were further problems. I was also advised by the dealer that this is a known problem with 6.2 motors and GM is aware of it. On (3-14-2025) I was told by Sun Chevy that the 6.2 motors are on backorder and I would have to wait approx 6 to 9 months. This truck is not even 1 year old and this is not acceptable in any way. I am paying on a truck that is not operable. I have always been a faithful Chevy owner however I cannot wait this long after buying a New Truck. I called GM to discuss options moving forward and them replacing my Truck. I can be contacted at [XXX], or [XXX]. According to GM This issue has been assigned a case number and that as far as it has gone. My famiky vacation now has to be cancelled as we were going to be traveling in the Truck and the Dealer stated that the loaner vehicle cannot leave the state. This is a complete mess. Any assistance would be appreciated. Respectfully, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Status: open (inferred from source dates) · Engine
On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure.

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.
