2021 Silverado with 5.3 engine/8spd transmission/38,000 miles just outside of the 5-year powertrain warranty *No current recalls under this VIN as of 10/07/2026* Undiagnosed issues with symptoms similar to transmission or rear end slippage, torque converter or clutch pack problems. No warning lights or messages have appeared 1) Vehicle seems to hunt for proper gearing between 30-40 mph (3rd to 4th gear) with light shuddering before shifting gears. Occurred 20+ times 2) Sudden jerk when taking off from dead stop. Feels like being lightly bumped from behind then drives normally. Occurred 4 times 3) Only noticed when towing appx 6,000lb trailer descending down a hill - A one-time loud clunk when easing off throttle and coasting downhill. The sound is similar to hitting a metal desk with a fist. Occurred 7 times. Spoke with local Chevrolet dealer who informed me the powertrain warranty has recently expired, and no repair cost would be covered. Recommended dealer service would be to replace the transmission fluid and filter with Mobil 1, potentially reprogram the transmission, and replace the torque converter. All on a vehicle with only 38,000 miles

At 124,000, the transmission started slipping and not grabbing gears. Coleman Taylor Transmissions ended up having to do a full rebuild which costs about $4000. At around 20,000 miles, the vehicle started to shutter going 45 mph. The vehicle still does shake violently at 62-75 mph causing a safety concern. The brakes wont go if Ive been standing still for a long time like in a drive through or backing down a boat ramp. You have to stand on the brakes with both feet to get the vehicle to stop and thats only going 5 mph. We still own this vehicle and still have issues with it.

The vehicle intermittently experiences transmission or drivetrain slipping, shuddering or juddering, and shaking while being driven. The symptoms are inconsistent and there is currently no check-engine warning light. The problem has not yet been diagnosed or confirmed by a dealer. I am concerned that the condition could worsen and cause loss of propulsion, unexpected shifting, or loss of control. The vehicle is equipped with a diesel engine and is within the model family described in the federal safety agency recall 24V‑797 involving transmission control valve wear. The vehicle and affected components are available for inspection upon request.

July 11, 2026 I experienced a lifter failure. Towed to GM dealer on July 13th. Dealer comfirmed lifter failure and camshaft damage and metal contamination throughout engine. Dealer installed replacement engine using my mechanical breakdown policy since I was out of factory warranty. Picked up truck one month later with new engine and the transmission started slipping and shuttering. Took back to dealer who claimed metal fragments in fluid and said transmission needed to be replaced. I then made a second claim on my mechanical breakdown policy and the dealer replaced the transmission. All of these issues are known issues with the engine and transmission.

I am reporting a potential safety defect involving my 2019 Chevrolet Silverado 1500 Z71 Trail Boss (VIN [XXX]), currently at approximately 63,000 miles. My truck suddenly developed a rough idle, engine ticking, and a cylinder 3 misfire. The check engine, traction control, parking brake, and “Service ESC” warnings appeared. The transmission also began shifting extremely hard, at times feeling as though another vehicle had struck the truck from behind. The oil pressure gauge also stopped functioning. Due to these symptoms, I stopped driving the vehicle. A diagnostic scan produced P0303, P0449, P0498, P0499 and P0500. After replacing a failed cylinder 3 spark plug, the truck initially ran perfectly for approximately 20 minutes before the rough idle and warning lights returned. The vehicle was subsequently diagnosed by a Chevrolet dealership. The dealership determined that the engine suffered a collapsed lifter that damaged the camshaft and other internal engine components. The engine repair estimate is approximately $10,000–$12,000. The dealership has also reported that the transmission is slipping and believes the torque converter/transmission requires approximately another $6,300 in repairs. I am concerned that a lifter/DFM-related failure causing a misfire, rough running and potential loss of engine power could occur while a vehicle is traveling at highway speed and create a significant safety hazard. The severe transmission shifting and subsequent slipping are also concerning because unexpected vehicle behavior during acceleration or while in traffic could increase the risk of a crash. The truck has been regularly maintained and has relatively low mileage for its age. I am requesting that the federal safety agency review whether similar engine/lifter/DFM and related powertrain failures represent a broader safety defect and whether an investigation or recall is warranted.

On Sunday, July 12, 2026, the 6.2L V8 (L87) engine in my 2023 Chevrolet Silverado 1500 ZR2 seized and locked up completely, resulting in total loss of propulsion. I was driving at 65 MPH when it felt like the transmission was slipping and I lost power and coasted the truck to the side of the road. COMPONENT: Engine (6.2L V8, RPO L87) — connecting rod/crankshaft failure consistent with Safety Recall N252494001 (the federal safety agency Recall 25V‑274). The vehicle is available for inspection. It is currently at Cable Dahmer Chevrolet, where it was towed on July 13, 2026, and remains inoperable. SAFETY RISK: The engine seized during operation, causing sudden and complete loss of propulsion in traffic. This is the exact failure mode identified in Recall 25V‑274 as increasing the risk of a crash. CRITICAL DETAIL: This vehicle previously underwent inspection under Safety Recall N252494001 and PASSED on Feb 3rd 2026 at VAN Chevrolet in Kansas City. GM deemed the engine non-defective and issued extended warranty coverage of 10 years/150,000 miles under the associated special coverage program. Despite passing GM's recall inspection, the engine suffered catastrophic failure. This appears directly relevant to the federal safety agency's open recall query regarding the effectiveness of GM's recall remedy. DEALER CONFIRMATION: A technician at Cable Dahmer Chevrolet has verbally confirmed the engine is locked up/seized. Formal diagnosis is pending master technician sign-off and submission to GM, expected the week of July 20, 2026. The manufacturer has not yet inspected the vehicle. WARNING SIGNS: No warning lamps, messages, or symptoms appeared prior to the failure. The engine failed without warning
