On 04/16/2026, while driving, vehicle received and completed a software/firmware ota update. A second update completion prompt was received while still in motion. Shortly after, while stopped at a traffic light, the auto-start/stop system re-engaged and the vehicle appeared to restart normally. Upon stopping to refuel, remote key fob auto-start failed to respond. Vehicle was started manually and driven to the next location. On arrival, remote key fob auto-start failed again. Used interior push-to-start — vehicle started but displayed an active check engine light. Connected vehicle app diagnostic scan of the engine and transmission system returned two warning flags requiring service: - transmission system — schedule service now - engine electrical system including charging and starting system — schedule service now all other scanned systems (air induction, fuel management, engine cooling, throttle control, ignition, variable valve timing, 4wd, displacement on demand) returned ok. Both faults appeared immediately following the ota update. Remote start failure at two consecutive locations and the check engine light activation are directly correlated in timing with the update applied on 04/16/2026. No fault codes have been pulled yet — dealership service appointment pending. This is not the first instance of an issue after updates are applied, between the infotainment system blacking out, rear camera or adas not functioning as well as sporadic crackling sound almost like electricity arcing in the engine compartment near the steering column.

2024 6. 2l silverado trail boss, engine failure at 22k miles on 4/13/26. Dealer confirmed the failure (not sure which bearings seized since engine has not been torn down yet, was either crank or rod bearings) and ordered a new engine 4/14/26. I was driving on the interstate and the engine started lightly shuddering during acceleration, showing some loss in power and shifting oddly but no check engine lights and nothing too alarming to immediately pull over. After several miles of this, the engine started to emit a loud metal on metal squeaking/scraping sound when on the throttle but stopped when I would back off the throttle. About a mile later, the truck just shut off at 70mph and went to neutral as I was about to get off an exit to evaluate the issues. Dash said push button to restart as I was coasting, but it wouldn't restart so I put on my hazards and pulled to the shoulder of the highway. Once stopped, it automatically shifted to park and would not crank or allow me to shift to neutral. Flatbed was called and brought it to the dealer. Side note: the truck passed the pico test 1/15/26 at 20k miles and was sent on my way with the thicker 0w-40 oil. Oil was changed every 5k miles and ran 93 octane.

Vehicle developed engine ticking/tapping noise followed by rough running and misfire condition. Independent repair facility performed engine teardown and found cylinder 4 exhaust camshaft lobe severely worn/damaged. Repair facility stated the exhaust roller follower/lifter needle bearings failed and fell out, causing the roller to seize and come off position, resulting in improper valve operation and cylinder malfunction. Vehicle lost proper engine performance and required major internal engine repair including camshaft, lifters/lash adjusters, and roller followers. Failure appears consistent with gm preliminary information bulletin pip5847b for 2019–2024 Chevrolet silverado/GMC sierra 2. 7l l3b engines describing exhaust roller follower bearing failure and camshaft damage. Concern is that sudden valvetrain failure could result in loss of power, engine failure, or unsafe driving condition.

When taking off it will sometime have hard shifts, shuddering, and acceleration hesitation. While driving, it will do static jolts. Dealer couldn’t pin point problem and advised for a new transmission or we could drive it until it dies. Dealer didn’t recommend to change transmission oil in fear of creating more damage.

On Sunday, April 12, 2026, at approximately 5:00 pm, I experienced a sudden and complete engine failure while driving my 2019 chevy silverado equipped with the 6. 2l v8 engine. Without warning, the vehicle lost all ability to accelerate, creating an immediate and dangerous situation for myself, my family, and surrounding drivers. I was forced to rely on the vehicle’s remaining momentum to maneuver to the side of the road, all while other drivers honked as I attempted to merge with no engine power. This incident caused significant stress and posed a serious safety risk. My vehicle had to be towed home and then to [xxx] casa Chevrolet at [xxx] . After inspection, the dealership informed me that the engine requires a full rebuild, despite the vehicle having only 115,697 miles. According to the dealership, the engine shows * compression on all cylinders**, **crankshaft and camshaft compression failure**, **pistons coated in oil and fuel with visible damage**, and a *?functioning timing chain likely due to a broken guide**. These findings mirror the exact symptoms currently under investigation in gm’s **ea25007** inquiry involving the 6. 2l v8 (l87) engines in 2021–2025 gm trucks and suvs gm has already issued a major recall affecting nearly *,000 vehicles** due to defective connecting rods and crankshafts that can cause sudden engine failure, stalling, and potential fire hazards. Although my 2019 silverado is not included in the recall, it is experiencing the same catastrophic engine failure associated with the defective components identified in the investigation. The dealership has quoted me $10,000 for an engine rebuild and has refused to assist with the cost. I have also filed a complaint directly with gm, as this failure presents the same safety risks and mechanical defects acknowledged in the recalled models. This sudden engine failure placed my family and other motorists in immediate danger, and the lack of w information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On April 11, 2026, my 2026 Chevrolet Silverado 1500 experienced a catastrophic engine failure while traveling on a public highway. The sudden loss of power created a significant safety hazard and could have resulted in a serious accident. I was able to maintain control and avoid a crash. The vehicle was towed to a dealership and diagnosed as requiring a full engine replacement. The vehicle has been inoperable for over 19 days, leaving my wife and me stranded far from our home in texas. This failure occurred without warning at highway speed and presents a serious safety concern that should be investigated.

I was traveling at highway speeds when the engine suffered a sudden and catastrophic mechanical failure without any prior warning lights or symptoms. The engine began knocking violently, locked up and put the truck into a brief skid before freeing up, followed by an immediate loss of oil pressure and a total loss of motive power. This sudden shutdown caused a brief loss of vehicle control as the power steering assist was compromised, creating a hectic and dangerous situation while I was surrounded by high-speed traffic. I was forced to navigate across multiple lanes to reach the shoulder. Crucially, this vehicle had the l87 safety recall (NHTSA recall 25v-274 / gm program n252494000) performed on July 8, 2025. The "remedy" provided by the manufacturer—which involved an oil viscosity change and a new oil cap—failed to prevent the catastrophic bearing/crankshaft failure it was intended to address. This represents a failed recall remedy that resulted in a life-threatening safety event. The vehicle is currently at a dealership awaiting a complete engine replacement.

* same part gone bad as other recalled vehicles. "coolant control flow valve bad". Engine fan is staying on high blast, message displaying " engine power is reduced" truck will not drive at full power because the truck thinks its overheating because of bad part. If I remember correctly, it is code p1098. Bad part is intermittent. It will happen randomly driving down the road. It comes and goes. I believe this is a safety factor . There is a special warranty or recall regarding this part with my year truck, but not my VIN? why not? same part going bad with same codes and same problem ? please consider looking into this concern and expanding the recall or concern for this reduced engine power safety concern. Thank you for looking into this.

I was traveling home one night and the truck shut off while driving and lost all power, loosing all steering, braking power aswell as all my lights while traveling down the road in the dark. . When I went to start it again all I would get was a cranking noise but no firing. After 30 minutes of waiting the truck started again. In which I drove it 3 more miles before it shut down again. After that it would not crank nor start. I then had the vehicle towed to my local Chevrolet dealer, and they had notified me that the engine had failed and locked up. In the process it had also taken out the fpcm (fuel pump control module) aswell as the high pressure fuel pump located on top of the motor. Causing me to have a new motor from gm installed. I had no previous problems or lights before this had happened.

Mccredy motors replaced the engine due to a recallin 6/2025. Husband was driving from our home [xxx] to town and we had made it to [xxx] . Husband stated there was no warning, no engine light, no oil lights, no indication of over heating. Just a loud clunking all of a sudden, nocking, grinding and crackling. Husband immediately pulled over left the truck over night at the greene town barn and we called in the morning to have the truck towed back to mccredy motors on the morning of 4/4/26. Reading up on this I have found the even after the recall and a new engine customers are still having catastrophic engine failures. This is absolutely what I feel we are currently experiencing. Mccredy motors will diagnose on Monday when the certified chevy dealership opens. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The 6. 2l v8 motor is known to have faulty internals. I was driving down the highway and the motor shut off. The vehicle needs a new motor now. Gm has offered an oil viscosity change to 0w-40. That was done 20k miles ago. This vehicle now needs a new motor.

Failed/collapsed lifters associated with known active fuel management (afm) issues. These issues are documented in technical service bulletins and I believe there are special campaigns for 2014-2018 l83 engine, but my VIN does not have a special campaign attached to it for some reason. I believe there are also class action lawsuits associated with these known issues, but a recall has not been issued.
