August 24, 2024 I was driving my 2022 Chevrolet Silverado 6.2 L V8 engine with 47,258 miles. I was traveling at approximate 65 mph. My engine siezed up and I had to pull my vehicle off of the two lane road I was traveling. The vehicle was towed to the dealership. Approximately a month after the vehicle engine seized because I did not have the funds to cover the repairs at the time of engine failure. Once the vehicle engine was diagnosed at the dealership I was advised that the repairs were under warranty. The repairs took appoximately one month due to waiting on new engine to be provided by the manufacture. My vehicle was returned repaired on 10/31/2024 with the same type of engine. I was advised that engine warranty would not be extended on the new engine. That this engine was only warranted under the old engine mileage and age.

I was driving down the highway at 60 MPH and a display warning came on the display monitor. It said shift into neutral and restart engine. Then the engine died and I had to try and get off the highway. There was a complete lose of power so getting off the highway was difficult without any power including steering. The engine would not restart and when to tow truck came about 2 hours later it still would not start or shift into neutral to be loaded. Eventually the tow driver got it to shift into neutral so he could loaded the truck. My safety was at risk because it was difficult to get off the road and had there been more traffic it could of resulted in a collision. I was in a dead area for phone service and I had to sit there for about 2 hours waiting for someone to stop and help me get to an area with cell service. The pickup was dropped off at the nearest GM dealership and they looked at it and the engine had a catastrophic failure. It requires a new engine, but since it is under warranty it may take up to 1 years for a replacement.

While attempting to merge onto the freeway from the "on ramp," the acceleration began to dissipate. I noticed the truck had shifted itself into neutral. I then had to put my emergency lights on and coast as long as I could. There was not a check engine light. The vehicle also would not restart. It was then towed to a Chevrolet dealership and the recommendation was to replace the engine. They had notified me that this was a common issue with this engine and they see this all the time. There were four trucks ahead of me at this dealership alone. The story was the same and neighboring dealerships. At the time, they were not able to estimate the time for repair to be complete. This was a safety risk since there were cars behind me and the vehicle lost power. This could have resulted in an accident and caused injury to myself or others. There is also risk being stranded on the shoulder of a major freeway awaiting a tow truck.

While driving under normal conditions the 6.2 liter engine in my truck locked down. I was traveling at 70mph in Interstate traffic at night and the vehicle shifted into neutral on its own and had no power. The truck then prompted me to press the start button. Unbeknownst to me at this point the engine had seized up with no warning so I pushed the button which promptly killed all my electronics, lights, etc. Thankfully I was able to "bully" my way towards the shoulder in traffic and roll off the road before I completely lost momentum. The truck would not restart on the shoulder. Towed it to my own shop where we determined the engine had seized. The truck has since been taken to the dealership for warranty work. The truck has 40,000 miles on it at the time of failure with no prior signs of issues. I have been a driver for 24 years, driving class V trucks daily for most of that. I don't know if the average driver would have avoided the potential collisions trying to get off the road with no power that I frankly feel I was lucky to do.

At 28000 km my 2022 Chevrolet trailboss 1500 with the 6.2 started to burn oil. It was averaging 1 litre every 2000km. The dealership told me this was perfectly acceptable for consumption on this engine. From 28000 km to 45967km I had it in multiple times due to low engine oil warnings and loss of power. At 45967km I took it to another Chevrolet dealership and they inspected my truck and determined that it was caused by piston and rings. This was done under warranty. I got the call stating my truck will be ready they are just doing a test drive to confirm the issue is fixed. When I got to the dealership they informed me it was ticking and they had to investigate further. During the test drive it collapsed a lifter. After they took my engine apart for a second time this was fixed I got my truck back. Over the course of the next month sitting my truck gave me headaches and made me sick. I found out that exhaust was leaking into my cab through my vents due to a 4 head gas monitoring device. I notified the dealership and made an appt. At 47434km my truck collapsed another lifter while I was on the highway with my wife and children in the vehicle and it started to violently shake with vibrations while trying to maintain or accelerate, all the warning lights in my dash went off and I lost all safety systems. I booked it back into the dealership to have it repaired and asked to have the engine replaced as I have had nothing but problems with it and was not happy with this truck or its reliability. I reached out to Chevrolet Canada at this point and asked to have my engine replaced or my truck replaced because this truck has had nothing but problems (many more outside of the engine) and they apologized and said the best they could do was offer me a hat. I have all service records and all service has been complete at Chevrolet dealerships. Truck has no current engine problems but still has many other problems.

My 2022 Chevrolet 1500 Trail boss (L87 V8) with 65,135 was making a clicking noise. I proceeded to make a service appointment with my local Chevrolet dealership on 05/03/2024. As I showed up for my scheduled appointment, I was turned away by the dealership due to lack of staff. I was told by my service advisor that my truck should be fine to drive for a few days till my rescheduled appointment on [XXX]. On my way to the dealership for the newly rescheduled appointment, my truck engine shut off unexpectedly and without any visual indication of engine problems. I had to call a tow company to take my truck to the dealership. Per the dealership's review, I was told over the phone that my engine had "locked up" and I would have to replace the entire engine. I was a couple thousand miles outside of warranty... the dealership told me there was nothing they could do to assist me with the cost of the new engine. This morning on social media, I saw that NHTSA is doing an investigation of the horrible experience I went through.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).
