The check engine light came on and my engine would stall sometimes, it would stall at start up so no safety issue. I took my truck to the dealer a week later where they said a wire was corroded from rubbing on something causing the issues and that it was a common issue.

While driving on the road at/or about 45 mph to my workplace, the transmission gave out and lost forward momentum. I had the transmission serviced for its second serivce at 84705 miles just ten days before this happened. The first service occurred around 47k miles when I learned about this issue with Chevrolet transmissions.

This complaint is in relation to the investigation into the GM L87 (6.2L engine) investigation. I own a 2024 Chevrolet Silverado with the L87 engine. I had my truck inspected through the recall a few months ago and the engine passed at that time. The engine oil was changed by the dealer per the recall at that time. On August 23, 2026, I was traveling at highway speeds on an interstate highway when my truck began to lose power, downshifted hard three times and died in the middle of the highway. The truck shifted to nuetral and I was able to coast off the highway into a rest area. I attempted to start the struck but nothing happended. I had the truck towed to a dealer. They inspected it on August 25, 2026 and determined the engine had a catastrophic failure and needed to be replaced. I am currently waiting on a replacement engine

I was told that my vehicle has a bent exhaust valve, which has caused irreparable damage to the engine and requires a complete engine replacement. The dealership could not determine what caused the valve to bend, but they indicated that it could potentially be a manufacturing defect, although they could not confirm that. My vehicle has now been at the Chevy dealership for more than 30 days, and I was informed that there are currently no replacement engines available from the factory due to a shortage. Given that this appears to be a known parts shortage, I assume other owners of the same make and model may be experiencing similar issues, although I cannot confirm that. The vehicle has approximately 10,000 miles on it.

The contact owns a 2016 Chevrolet Silverado 1500. The contact stated that while attempting to make a left turn from a complete stop, the vehicle lost motive power while depressing the accelerator pedal and was stranded in the middle of traffic. No warning lights illuminated. The vehicle was placed in neutral(N) and pushed to the shoulder of the road. The contact's husband arrived at the scene and restarted the vehicle; however, while driving at low speeds, the failure recurred. The vehicle was towed to a dealer, where it was diagnosed with metal shavings in the transmission. The dealer informed the contact that the transmission needed to be replaced. The vehicle was not repaired due to the repair costs. The check engine warning light illuminated. The manufacturer was notified of the failure. The failure mileage was approximately 120,000.

The lifter rod associated with the DoD/AFM system failed, causing catastrophic failure in the engine. This isn't an age issue, this isn't a part that wore out and failed. This car would still be running and driving if that system was never installed. The lifters for these systems are known weakpoints that'll eventually fail. Because of this we lost immediate power in the vehicle and had to immediately pull off to the side of the road on a busy road. I had my local shop take a look and they confirmed that it was a lifter issue. No others have inspected this as this is chalked up to the age of the vehicle. There's no warning for this failure. One second you engine is running great, you apply for some more power, and it fails. Ruining the rest of the engine with it.

Had the recall service done , where they change the oil weight, to the 6.2 L engine and just a few months later the engine died while driving on the highway . It just stopped running. The car is only 3.5 years old and the engine died. They took it apart and said it was a non effected part that failed but i find that crazy. No warning just complete shut down. I was luck and only going about 30 MPH on the highway due to heavy traffic. But then needed to sit on the highway for hours weighting for a tow. The kicker is the car would not go into neutral and made everything so much harder.

Purchased used in 02/2022. Pickup started to shutter when shifting at 35-45 MPH. Took it to Turnpike Chevy who found thrust bearing in reaction carrier broken and damaged planetary gear set. They replaced the reaction carrier ASM and Reconditioned the transmission ASM. Replaced the valve body ASM. Took to John Sauder Chevy numerous times between July 19 2024 and July 7 2025 due to the shutter when shifting having returned. They tried the GM approved fix of flashing the computer to reprogram and kept saying they could not duplicate. On June 18, 2025 while towing a trailer on the highway while going highway speeds in the middle of rush hour traffic the transmission suddenly started making a shrill noise. Transmission disengaged and lost power. John Sauder Chevrolet found a broken oil pump drive and drive gears on the 10L80E transmission. GMC refused to replace the transmission and now it is out of warranty and starting shutter again when it shifts

My Second motor blew up while towing my camper with my entire family in the vehicle, leaving us stranded 1 foot from interstate traffic for over an hour as we waited for a tow truck—this was GM's 3rd attempt to fix the problem. There were no warning signs. The motor had roughly 4 thousand miles on it. I have since gotten rid of this truck (and suffered financial loss) before it gets me or someone else killed. GM needs to fix this. o30,317 miles – Started using Heavier oil 6/18/2025 o36,732 miles – Recall “fix” 11/10/2025 o38,917 miles – 1st Engine Failed 1/9/2026 oTruck returned to me – 1-24-26 o43617 miles – 06/20/2026 Replacement motor blew up I can't remember the exact speed, but I was going with the flow of traffic, so I'm going to guess it was 70-75. The file CTCS654636 is the second motor failure. Starr RO 626023.pdf is the first engine failure. and i have also uploaded the two files of when i swapped oil and had the recall fixed.
