general problems of the 2024 Chevrolet Silverado 1500 - part 1

Oil cooler failed and truck was at dealer for a month over winter. Now June 20th transmission failed and there is no timeframe on the valve body. I am still making payments on this truck and no dealers have a timeframe.

Engine seized middle of road had to coast off into a safe spot to park.

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.

L87 engine failure.

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.

Truck engine shut off doing 60. Has major recall and issue these trucks are unsafe I was very scared.

L87 6. 2l engine failed. Loud knocking, no oil pressure, engine stalled and would not restart. This happened despite gm's recall where they changed to 0w40 oil.

Vehicle had died before and was brought to dealer but was restartrd, no problem could be found. Two weeks later, engine locked up on a 70mph highway. With children and wife in vehicle. Could not restart. Had to be towed to dealer. No previous lights or warnings before engine locking up.

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.

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 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.

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.

These are two separate incidents. The first one is the seat moves to the left or to the right given the direction of the vehicle. The other incident was when I was reversing into a parking spot. The gear shifted out of reverse and just was in a floating stage. I then had to put it back into reverse to continue it did it twice.

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.

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.

Turning into the driveway and the truck shut off. Place in park and the truck started right back up.

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.

Truck shut off while driving in traffic managed to steer it off the road, towed to dealership with p0016 code as well as a bunch of others. Known recall issue passed gm pico test a month earlier. Now when I log in here to view recalls it says 0 recalls not repaired. Now truck has to get a new engine.

Summary of incident: on March 28, 2026, while traveling at 70 mph on the florida turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into neutral or park. The engine cranks but will not start. 1. Component failure & availability: the exact component is currently unknown, but the failure involves the powertrain, fuel system, and electronic transmission control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or NHTSA upon request. 2. Safety risk: the sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem reproduction: the vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: the vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning symptoms: there were no warning lamps, "check engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

What is happening with my vehicle is a major safety concern in my opinion for myself and for my family. I purchased the vehicle on February 18,2026 from ryan Ford in sealy,TX with approx 32,800 miles. The first incident was on March 16 with 33,718 miles, my daughter and I went to leave the lowe’s parking lot and my vehicle would not go in reverse. It however would go in drive, so after being pushed back out of the parking spot we left for our home. (this part of not going in reverse I do have on video) once on the feeder road and up to approx 45mph my vehicle went completely out of gear and had to coast to a stop on the side the road. Turned vehicle off and on and it went back in gear, after making it home I made and appointment with the dealership and dropped it off that day. I was informed no codes came up and the dealership could not get the issue to duplicate so I received my vehicle back. The second incident was on March 21 trying to leave the convenient store, I put my vehicle in reverse and pressed on the gas to go backward and nothing happened. Then I pressed on the gas again and it threw my vehicle in reverse and jolted my truck back several feet before I could press on the brake. Luckily no one or no object was behind me. The third incident was on April 3rd trying to leave walmart. My truck would not go in reverse again. I pressed the gas pedal several times and out of nowhere again it threw itself in reverse and jolted my truck back again. (I also have this on video as well).

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.

Engine failure, list of power in the number 3 lane roll across traffic pattern to side of road avoiding a rear end collision, yes on second engine 6. 2 yes engine has been inspected and replaced no warning with both times of engine failure.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving approximately 55 mph, the vehicle started jerking and shuddering before it stalled. There was an abnormal grinding sound coming from the engine compartment. There was no warning light illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was repaired. The contact researched online and related the failure to NHTSA campaign number: 25v274000 (engine and engine cooling); however, the VIN was not associated with the recall. The manufacturer was informed of the failure. The failure mileage was 13,222.

I had my oil changed and the next day the check engine light came on. I looked on the chevy app to see what it was and it said varuable valve timing issue. I click further into the app warning and it said, engines equipped with this system use sensors that regulate the opening and closing of the intake and exhaust valves to optimize performance and efficiency. I live 3 and a half hours away fro. The dealership so I had some mechanics look at the truck just to see if they could pin point what the issues was exactly. They didnt pull or work on anything just looked around listened and plugged in a code reader. The code reader found some codes that had to do with 3rd stage valve timing issues and vvt. And 1 or 2 other codes. But they didnt know exactly what was wrong. I had my oil changed 1 more time to see if maybe that was the issue. It did not fix the issue. I called the dealership to make a appointment. I brought it in and get a call that the cam shaft need to be replaced. It was in the shop for about a month and when they said it was ready. I went to pick it up and as I was pulling out of the dealership parking lot. The check engine light came on and I drove back and it had the same codes. And now it is being worked on again. The safety side is if it looses power while im going 65 mph it could be really dangerous. Becaue there could be metal shavings in the oil possibly.

Gm replaced engine after a complete failure associated with a defective engine recall. The remanufactured or new engine installed seems to have a similar defect as the original engine. Returned vehicle for service and was told gm refused to repair or replace the engine until the vehicle suffered another complete engine failure. Regardless of any safety concerns of an another complete engine failure.

My truck engine stopped working while driving down the road causing me to lose power and I was not able to exit the roadway. There were no warning or messages until the loss of power and dash stated to "restart the engine". This was not possible. The truck was towed to a chevy dealership and they confirmed the engine seized up do to unknown engine failure. This is a 2024 6. 2l engine with 45000 miles that is not under recall. The dealership replaced the engine under the powertrain warranty.

The cam crankshaft failed. I was driving on the highway at a speed between 65-75 and my truck just cut off without any warning. Luckily, I was in far right lane and coasted over to the side of the road but it was very scary because I didn't control my truck at all. I called the nearest Chevrolet dealership that was kevin whitaker and they give me the Chevrolet help contact phone and they sent a tow truck to pickup my truck about 1 hr later and I was stuck in my truck on the side of the road and I couldn't get out on the drive side because how close it was to oncoming traffic. Once I arrived at the dealership with my truck after asking the tow driver could I ride with him to the dealership. At the dealership they checked the truck with computerized device and the service advisor told me the truck code revealed cam shaft problems. I told him that I did see and warning sign saying low oil pressure once I tired to start up the truck again on the side of the road.

My engine shutoff while I was driving on the highway. I had the initial recall remedy performed on my 6. 2l 2024 silverado truck by getting the thicker oil about 8 month's ago. Now my truck is in the shop I'm suppose to be getting a replacement engine. I'm not sure if I can trust the replacement engine im getting.

I have a 2024 silverado with the l87 (6. 2) engine. I brought in in for recall. After inspection the Chevrolet service center said it was good. They changed the oils to 0-w40 per the recall. On January 8, 2026 I was driving at 35 mph and the engine just stopped. I had it towed back to the Chevrolet service center and after diagnosis it was determined that the engine failed and has to be replaced which take a month or more.

5449 miles. Motor had a knock. Took to dealership and they replaced valve lifters.

Thrust bearing failure at 11,945 miles requiring complete engine replacement.

Vehicle simply died in the middle of an intersection and blocked the roadway for an extended period of time before being towed back to dealer. Engine failure confirmed, replacement has been ordered.
