2024 Chevrolet Silverado Engine Problems

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.

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.

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.

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.

Loud ticking sound from engine corresponding with engine speed (faster as the rpms increased). Took in to dealership out of concern and the rod bearings were spun necessitating a full engine replacement. This was only 4 months after it passed the inspection for Recall - L87 Engine Loss of Propulsion (Related field action: See Special Coverage N252494003).

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.

After taking in to dealer for recall diagnostics and higher viscosity oil change a couple months later. Heard a noise while driving on interstate, lost cruise control, stability system, engine light came on with a ECS. Kept driving on the interstate until we got to a red light and the engine died. Cranked starter but hard to start and ran rough and died multiple times. Feathered throttle to get over 1K RPMs to get it off the street. Towed to nearest Chev dealer. P300 code. Tore engine down. Here is what dealer documented: CUSTOMER STATES CHECK ENGINE LIGHT IS ON WITH SERVICE TRACTION & SERVICE ESC MESSAGES. ENGINE IS RUNNING ROUGH AND WILL STALL. TOW IN. Valve Spring Replacement - Replacing the faulty valve spring on the cylinder 7 exhaust side is necessary as it is causing the exhaust valve to remain stuckopen, leading to engine misfire and over 80% leakage in that cylinder. This service can help restore proper engine compression and improve engine performance. Op.1 CEL -CEL: Customer states 1. replaced the exhaust valve spring and valve spring seal. reinstalled components with new seals and cleared dtcs. started engine and verified the engine starts and runs but having multiple cylinder misfires. reset engine fuel trims and brought engine to operating temperature and let it run for some time. other cylinder misfires went away but still found a dead misfire on cylinder 7. removed and swapped spark plugs with no change. noted the spark plugs have some exhaust build up on the tip due to the faulty exhaust valve spring. performed a static compression test and found the compression to be 175 psi and a running compression test with a smooth build up to 125 psi. checked spark and spark was good. tested the injector system using the AFIT test and found the test to pass indicating no faults with the fuel injectors. performed a cylinder leak down test and found no cylinder leakage coming from cylinder 7. put engine back together and cleared dtcs. reset the throttle

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 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.

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

Vehicle died and would not move forward or in reverse. The engine locked up and had to be replaced. Recall to test engine and replace with thicker oil was performed 6000 miles previous to engine failure.

Regarding Recall Repair on My Truck To Whom It May Concern, I am writing to formally express my frustration and concern regarding the recent service performed on my truck, which I purchased pre-owned from Tropical Chevrolet with only 4,700 miles. 9 months after my purchase, the vehicle received a manufacturer recall involving the motor, requiring a full engine replacement. I brought the truck to Bomnin Chevrolet West Kendall for the recall repair, expecting that it would be handled correctly and at no cost to me, especially since the truck was running perfectly before the recall work. After the motor was replaced, I was informed that the Air intake manifold currently on the truck is “not original.” This Air intake manifold was already installed when I bought the truck from Tropical Chevrolet, and I was never informed of any aftermarket or non-original parts at the time of purchase. Now, after Bomnin Chevrolet completed the recall repair, the truck has a check-engine light, and I am being told I must pay approximately $900 to change it for original air intake manifold to remove the check engine warning light. I think the mecanic took out the program.from the computer and Now they want me to pay.This is unacceptable for the following reasons: 1. The truck had no check engine warning lights and was running properly before the recall repair. 2. The Air intake manifold was already on the truck when I purchased it from Tropical Chevrolet. 3. I never approved or installed any non-original parts. 4. Bomnin Chevrolet removed and reinstalled the parts during the recall repair. 5. I should not be held financially responsible for problems created during the recall repair process. I am requesting that this matter be reviewed and resolved immediately by Bomnin Chevrolet West Kendall. The truck should be returned to me in the same conditions I gave it to them and the recall fix.Thank You Regards, Rafael Lafee
