On October 27, 2026, my 2022 Chevrolet Silverado 1500 LTZ with the 6.2L engine suddenly lost propulsion on Interstate 80 near Atlantic, Iowa. The mileage was approximately 62,000, although I am uncertain of the exact mileage. I had driven approximately three hours after leaving my hotel that morning before stopping at a gas station. When I restarted the truck, the engine barely turned over before starting. No engine warning lights came on at that time. I continued onto I-80. Approximately five minutes later, the truck began losing speed with cruise control engaged. I disengaged cruise control and pressed the accelerator. The engine revved, but the truck did not accelerate. The check engine light came on just before the truck shifted itself into neutral. I coasted to an off-ramp, and the truck would not restart. It required towing. The sudden loss of propulsion at interstate speed put me and surrounding traffic at risk because I could no longer accelerate or maintain speed. The dealership inspected the truck and told me it failed what they described as a “propulsion test” and was included in a recall. The specific internal component that failed is unknown to me. Whether the failed components have been retained and are available for inspection is also unknown to me.

Driving on I-64 approx. 75 MPH, I heard a noise coming from what seemed to be the engine; sounded like a belt or hose whipping in the wind-did not sound metallic in nature. I turned off radio and opened window and could not determine source. Within 20 seconds or so, I had lost motive power and vehicle began slowing down, despite applying gas pedal. I did not have any warning lights. Oil pressure seemed okay, RPM stayed just under 2k. Once vehicle slowed down from 75 to about 60 mph I steered vehicle off roadway. I turned off engine and opened hood to inspect. I had light smoke coming out of air filter. Oil was pouring out the bottom. Only then did I have a check engine light on and vehicle would not restart. Dealer inspection determined what I suspected (from previous years 6.2L recalls), thrown rod through the engine block. The service rep said he personally saw the rod sticking out the side of the engine block.

Was driving for about an hour pulling our 7,000 lb camper when all of sudden my daah lit up with all kind of lights and warnings. The messages were Service Trailer Btake System, Service ESC, Service Parking Brake, Brake System Failure 62mph top speed, check engine light, Traction Control Off, ABS Off. Pretty much had no brakes and had to use the manual gear selection to slow down from 65 mph. Not a good feeling wh no brakes pulling a camper. The brake pedal was hard and used everything I had to get it to go in to try to stop. Now my rear brakes on the truck currently making all kind of noise and the truck went to the mechanic today.

2019 Silverado 1500 6.2L, #3 lifter/cylinder collapsed while just getting up to highway speed on [XXX] near [XXX], Wagonmound NM, on Saturday, [XXX]; heard a LOUD bang, followed by message center stating stabilizer control was turned off, followed by FLASHING check engine light. We were towing “dry” Northwood 17k Nash, with our three dogs. As soon as we realized the truck was in the danger zone, we pulled over as quickly as possible. Both truck and trailer had to be towed 40 mi south to Las Vegas NM. The driver dropped our trailer at a local RV park and dropped our Silverado at Las Vegas Diesel Repair. We had to leave the truck in Las Vegas as having it hauled to Longmont Colorado, where we live, would have been too expensive. It’s been seven weeks; getting a new, rebuilt, deleted Jasper engine was my only choice. We stayed through the weekend, had to rent a UHAUL box truck to get home, as car rental was not a one-way option; this cost $500 and the tow was $600, insurance reimbursed $400. We were stranded on [XXX], with three dogs for well over an hour, so dangerous for us. I feel fortunate that the truck didn’t start on fire due to the fact that raw fuel was dumping into the catalytic converter due to the lifter collapsing into the CAM shaft. AS I HAVE COME TO LEARN, GM IS PROFOUNDLY AWARE OF THE LIFTER PROBLEM, ESPECIALLY IN THE YEAR/MAKE/MODEL OF MY TRUCK AND HAS MORBIDLY FAILED TO NOTIFY OWNERS OF THE DANGEROUS CONDITION THIS PRESENTS. IT’s my understanding that there is a class action lawsuit against GM in the works and I WILL be in on that action. We’re talking 100’s of 1000’s owners that are unaware of the danger their vehicle presents…I didn’t know and I researched recalls on my truck BEFORE I bought it used with 92,000 miles a couple of years ago. It has approximately 123,000 on the engine that’s being replaced to the tune of $15,000~. Virtually everything under the hood has to be replaced, final bill is pending; $7000k to start work INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (F

On October 18, 2026, I was driving my 2021 Chevrolet Silverado 1500 with the 5.3L V8 engine at highway speeds with my wife and two young daughters in the vehicle when the engine suddenly lost power and the truck began shaking violently. The check engine light flashed, and "Service ESC" and "Service Parking Brake" warnings appeared on the dashboard. The sudden loss of power at highway speeds created a serious safety risk to my family and surrounding motorists. I was able to get the vehicle off the highway safely. Restarting the truck did not resolve the issue, and it was no longer drivable. The truck was towed by a AAA contractor to a Chevrolet dealership. Following inspection, the dealership verbally diagnosed a broken camshaft and advised that the entire engine required replacement. The truck had approximately 98,000 miles at the time. A written diagnosis has been requested, and the vehicle is currently at the dealership. The truck has a documented history of engine problems. In July 2023, at approximately 33,500 miles, a Chevrolet dealership diagnosed code P0300 and documented misfires on cylinders 1, 3, and 7. Warranty diagnostic and repair work was performed. Another check engine light concern was documented in November 2024 at approximately 62,300 miles. In April 2025, at approximately 69,600 miles, Chevrolet again investigated a P0300 multiple-cylinder misfire condition. Beginning around 75,000 miles, the truck also began displaying recurring low-oil warnings. I added oil whenever these warnings appeared and maintained regular oil changes, supported by service records. Despite these prior engine concerns and dealership visits, the engine suffered a catastrophic failure without an immediate warning before reaching 100,000 miles. I am concerned about the potential for sudden engine failure and loss of propulsion at highway speeds and believe this warrants a safety investigation.

Incident: Twice our Chevrolet Silverado 2020 Duramax has experienced while operating, sudden with no warning "reduced engine power" and "check engine light" the engine sounds very different and does not operate as it should and presents a safety issue when you are driving and traveling at a high rate of speed. These incidences occurred on 10-4-2026 and 10-23-2026. The vehicle experienced a sudden failure of the engine coolant control valve, triggering Diagnostic Trouble Code P1006. This component failure restricts proper engine thermal management and poses a risk of sudden engine overheating while driving. General Motors has formally acknowledged this identical part failure as a chronic manufacturing and safety defect via Special Coverage Bulletins N252508341 and N252508340, which extend warranty coverage to 15 years/150,000 miles. However, GM has arbitrarily excluded the 2020 model year from this coverage, despite the vehicle utilizing the exact same defective part assembly number as the covered 2021-2023 models. This identical component failure across model years constitutes an unaddressed defect pool that requires immediate regulatory expansion to protect consumers from unsafe engine component failure. please fix this situation TY
