While I was visiting my mother in Kentucky my 6.2 truck engine failed. It all happened really quick and no warning signs prior. Truck passed recall in April 26. I just left visiting my mother at nursing home. I was on Mountain Parkway when it all of a sudden started making a noise. It sounded like it was coming through firewall. All of sudden check engine light came on and I pulled over right before off ramp. I turned truck off for couple of minutes and started it back up. No light but as soon as I pulled back onto parkway noise started again. I was next to off ramp so I pulled into Marathon gas station and as I was pulling in it died and wouldn’t start back. Truck was taken to dealership on 5/24. They said they can’t give me a courtesy vehicle due to me living out of state and I would have to get a rental on my own but GM would cover up to $44 per day. I contacted GM twice and said I needed to speak to dealer about getting a car. I explained what dealer told me but they said it was out of their control. Still paying for rental out of pocket. Dealer called and verified that engine needs replaced and new engine is back ordered with no ETA. I’m still paying truck payment on a truck I don’t have and no help from GM on giving a car to drive. Need help with escalating new engine replacement and rental that GM is covering.

The 6.2 liter engine has been recalled. The problem is if you pass inspection you are now required to use a higher grade of oil. This results in an additional cost of about $50 per change. The reimbursement of the difference should have been covered by the recall as this was not an intended cost when I purchased the truck.

On [XXX], I was going to Atlanta, the truck started hesitating harshly while I was passing another driver on a two lane road. The truck wouldn’t accelerate and the paddle seemed to be stuck, I had to pull off the road to avoid a head on collision. On the 30th of May, I took the truck to Allen Turner in Pensacola, Florida where I purchased it and reported the issue, the service department was closed and they sent me next door to a Chevrolet Dealership, which was also closed. On today [XXX], I took the truck out for a test drive, and I had the same incident happen, but this time I pulled into a gas station and shutdown the truck. Once I turned the truck back on, the check engine light came on. I didn’t think I would make it back home, because the truck didn’t accelerate correctly, and when I pressed the gas pedal it didn’t accelerate and was making different noises. The pedal seemed to be stuck, with no acceleration. I recorded a little bit with my phone while trying to drive, but it’s not the best.

Incident

May 15, 2026

The primary failure is in the electronic transmission control system and engine wiring harness assembly, specifically throwing diagnostic trouble codes P0700 (Transmission Control System Malfunction) and P0717 (Input Speed Sensor Circuit No Signal). The authorized dealership identified a critical issue with the engine harness chafing, but their subsequent repair attempts have failed to resolve the recurring powertrain failure. The complete vehicle and all affected components are currently parked and fully available for immediate physical inspection at my residence upon request. While operating the vehicle at highway speeds, the powertrain abruptly loses throttle response and forces itself into a severe, uncommanded "Reduced Power / Limp Mode." This creates a severe safety hazard by instantly dropping vehicle velocity on active interstates and high-speed roadways, leaving the vehicle unable to accelerate out of harms way or merge safely, placing myself, my passengers, and surrounding motorists at immediate risk of a high-speed rear-end collision.The malfunction has been repeatedly confirmed and documented by authorized GM service agent Rountree Moore Chevrolet (Lake City, FL) across three separate service visits. The dealer confirmed the active trouble codes and attempted various repairs (including Transmission Control Module reprogramming on 04/24/2026, engine harness chafing repairs on 05/19/2026, and auxiliary fluid/battery adjustments on 05/21/2026). The persistence of the failure confirms the dealer has been unable to successfully remedy the defect. To date, the vehicle has only been inspected and worked on by the authorized dealership's factory-trained technicians. It has not yet been involved in a collision requiring police or insurance representative inspections, nor has a corporate field engineer from General Motors inspected it outside of the local dealership level.The failures are consistently preceded by an illumination of the dashboard Check Engine

I was driving home from work, and dash warning sign came on and told me to start engine. I was currently driving at approximately 60 mph. When i came to blinking red Light i went to accelerate and truck was unresponsive. it would not accelerate and engine was off. I went to start engine and it just cranked with no start. I used onstar to get a tow truck. I was broken down in the middle of an intersection and had to wave traffic around me for 1hr 45 min. Finally tow truck came and took truck to local chevy dealership. Upon inspection they stated that it needs a new engine. I had the truck in the chevrolet dealership in feb 2026 to have the 6.2 recall done, they performed the full recall and said everything looks good. truck has approximately 60k miles on it. it failed a few months after inspection. They stated they have ordered a new engine and it would be approximately 4-6weeks minimum. Truck is sitting at the dealership

Incident

Apr 30, 2026

While exiting a highway via an off-ramp, the vehicle experienced a sudden mechanical failure consistent with internal engine/bearing failure. During deceleration on the off-ramp, the engine began to shudder violently and immediately lost power. The vehicle was unable to maintain normal operation and became unsafe in an active traffic environment. After coming to a stop, the engine would not restart and the vehicle was completely inoperable. There were no prior warning signs or alerts before the failure occurred. The issue developed abruptly while the vehicle was in motion. The vehicle required towing and dealer inspection. Diagnosis confirmed internal engine damage / bearing failure / engine seizure. The repair required engine replacement This failure is consistent with widely reported issues involving GM 6.2L V8 engines (model years 2019–2024) experiencing bearing failure and catastrophic engine damage. The same failure characteristics appear to be present in this vehicle. This represents a serious safety concern due to the sudden and complete loss of engine power and inability to restart the vehicle while in a traffic environment, creating risk of collision or roadway obstruction. The vehicle had approximately 65,000 miles at the time of failure.

I am reporting a safety defect involving a GM 6.2L L87 engine. My vehicle was included in the GM recall related to engine failure (loss of propulsion). The recall remedy was performed, and the engine was replaced under recall/warranty in August 2025. After the recall repair and engine replacement, the vehicle experienced a second catastrophic engine failure, on April 21st. The engine failed again while on a highway, resulting in loss of vehicle function and leaving me stranded. This occurred after the manufacturer had already attempted to remedy the defect. The vehicle has now been out of service for an extended period (approximately 2.5 months total across both events - and ongoing), and I am continuing to make payments on a vehicle that is not operable. This appears to be a failure of the recall remedy itself, not just the original defect. I am concerned this represents a broader safety issue involving post-recall failures of the L87 engine, as currently under investigation. I am requesting that this incident be included in the ongoing federal investigation into GM 6.2L engine failures.

While driving, the truck suddenly Boggs down and gets sluggish. A message appeared once that said reduced acceleration drive with care. It is dangerous because it loses power and stalls in front of other vehicles. I took it to the dealership on Friday the 17th and they said it was the crank position sensor. They ordered the part and I took it back on Monday the 20th and they replaced the sensor. Today, while driving down the highway it did the same thing again. I will be taking it back to the dealership tomorrow. The truck has 26,000 miles on it.

Apr 17, 2026

Was driving the truck on the highway at 75mph when suddenly the motor revved up in rpm’s and vehicle lost all power. There was no warning lights or any limp mode or anything as such as far as warning. The truck lost all power and could hear metal to metal sounds and turned off the motor. I was able to coast the truck to an off ramp in 70mph traffic. The truck would not turn back on and vehicle was immobile, had to have the vehicle towed by a flatbed to a gm dealer near by. The dealer gave me a loaner pickup and hasn’t looked at my vehicle yet. I bought this pickup less then 3 weeks ago and the L87 recall and oil change had been done prior to me buying it. I was just happy that the truck didnt full shut down at that speed and cause a crash etc. Dealer said motor failure to me and couldn’t confirm a turn around time frame for my truck to get back to me.

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

Incident

Apr 16, 2026

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.

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.
