Took 2025 silverado with a 6. 2l engine to get oil changed and tire rotation done. Upon completion drove out of dealership and notice a weird noise coming from engine, then kind of disappeared. Drove home. Wife took car for gym then suppose to go to work. She called stating engine sounded really bad, like a lot of metal and metal screeching. Went to dealership, explained and they towed truck to service department to be looked at on 12/22/2025. Safety to others would have been detrimental if the vehicle had seized on the highway. The dealer person who sent for the tow was not the service manager but when we arrived he heard what the vehicle sounded like. No check engine lights or any warnings on. Hope to have results on Monday.

Lifters failed causing complete engine failure gm won’t cover engine replacement but it goes along with the other engine failure lawsuits against gm.

I bought the vehicle with 14000 miles. Had oil changed at dealership ever ,5000 miles. I drive 10 miles a day. At 55000 miles the lifters are ticking like a time bomb. It makes me sick that a vehicle with no more miles than this is in this shape. Gm should stand behind there junk motors with this afm.

While driving at a speed of approximately 55 mph, the vehicle suddenly displayed a flashing check engine light, esc error light and stability control warning light on the driver cluster. The vehicle made a loud series of noises and suddenly lost power. The loss of power reduced my ability to control the vehicles acceleration while in traffic creating an immediate traffic hazard. Garage recovered vehicle by tow and found lifter failure, camshaft and cam bearing damage with significant metal shavings throughout engine requiring engine replacement. Repair is estimated at $12,000.

Nothing yet. Between doing research and general observation the dod/afm is a known issue for these motors. The engine will randomly loose a valve and cause the engine to shut down causing for a major saftey concern if traveling or towing.

Driving down a single lane road at aprox 30-35 mph, when without any warnings the engine began to make a noise (like it was eating rocks), smoke began billowing out the tail pipes, the dash cluster lit up with error codes (unable to read due to attempting to get vehicle off the road), engine completely stopped, dash cluster would only show the check engine light, when attempting to get the vehicle towed it could not be put in neutral and the parking break had engaged and would not release. Vehicle was towed to nearest dealership and they confirm the engine had "seized" and would need to be replaced. Existing engine has 4190mi. If this had occurred on the highway or busy street I dont feel I could have safely gotten the vehicle out of harms way.

Purchased new and after 3 weeks (about 600 miles) I was on highway between 60-70 mph truck started to shutter like it was losing power and would not accelerate. I complained to the sales person and he stated it ran a little rough when purchased first day - I was told it just needs to warm up. Took truck to dealer and they determined at this time it was a misfire and lifter bank issue. There seems to be an issue widespread - I am not comfortable with car and if on the highway I am not able to accelerate properly or becomes unreliable at the time to accelerate I am worried about safety.

Afm/dfm on my 2015 Chevrolet Silverado 1500 lt had to lifters collapse without warning and no engine light was hole I had my 7 year old daughter and 10 year old son in the vehicle while I was driving. My kids got scared and I had to react quick and go into a drive way. While I was driving my vehicle gave out without warning and could’ve caused a serious accident to my kids and myself including other vehicles.

While driving the engine suffered a catastrophic failure and died. Fortunately I was already coming to a stop when it happened. Had I been traveling at speed I would have been seriously injured or killed along with any other vehicles I may have crashed into. The Chevrolet dealership where vehicle was purchased new confirmed it was a catastrophic failure of the gm l87 engine which has knowingly been fraught with these failures. They cannot confirm the exact nature of the failure without dismantling the entire engine at my cost which I have not decided upon doing yet as it will be very expensive. As far as symptoms or warnings I heard a sound from the engine compartment immediately before the engine died.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that upon starting the vehicle, there was an abnormally loud engine camshaft bearing sound coming from the engine. The engine warning light was illuminated. The vehicle was taken to the local dealer, and after three days, it was determined that the camshaft bearing had failed, and the engine needed to be replaced. The vehicle was not repaired. The contact linked the failure with NHTSA campaign number: 25v274000 (engine and engine cooling) and NHTSA action number: ea25007 (engine and engine and engine cooling). The manufacturer was contacted and opened a case. The failure mileage was approximately 45,000.

While driving at highway speeds, in traffic, all dash lights lit up and the engine shut off. The truck began decelerating on its own, I couldn’t brake and could barely steer. Luckily I was going fast enough that I managed to coast about a hundred feet to get partly out of traffic. The truck would never start again and I had to wait for 7 hours for gm roadside assistance to tow me to a chevy dealer that was 4. 6 miles away. 23 hours later the dealer called me and told me the starter caused the problem, in which I told them made no sense. 30 mins later they called and said the motor failed due to recall n252494003 for the l87 engine. My truck had passed the recall inspection for this recall on Sep 24th, 2025 and received the new oil that was supposed to prevent this failure. I had also just had the oil changed again around Nov 13th because the fcw module needed a firmware update and was not functioning. The truck had given no warning or issues previous to Dec 3rd.

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.

Component or system failure: the engine valvetrain (camshaft and lifters) sustained severe internal damage, including camshaft scouring, confirmed during inspection and teardown by an authorized Chevrolet dealership. In addition, the rear differential was found to contain no gear oil when the fill plug was removed during inspection. The vehicle and components are currently at a Chevrolet service center and are available for inspection upon request. Safety risk: the vehicle experienced persistent drivetrain vibration and abnormal operation that worsened over time and ultimately rendered the vehicle non-operable. Internal engine damage and a rear differential without lubrication present a risk of sudden drivetrain failure, loss of propulsion, or loss of vehicle control, particularly at highway speeds. The vehicle is currently unsafe to operate. Problem confirmed: yes. Engine damage has been confirmed by the dealership during teardown. The absence of gear oil in the rear differential was directly observed during inspection. Inspections by others: yes. The vehicle has been inspected by an authorized Chevrolet dealership and by third-party inspectors associated with the extended drivetrain warranty administrator. Two inspections have been completed, and a third inspection has been ordered. No repairs have been completed as of this report. Warning lamps or prior symptoms: beginning around approximately 21,000 miles (2022), the vehicle developed drivetrain vibration. The vehicle was taken to a Chevrolet dealership at that time, but the cause was not identified or corrected. No warning lamps or messages are recalled.

Oil cooler line separated.

November 28th 2025 we were coming down logan canyon in utah at 50 miles an hour when I was passing another vehicle on the left I felt a hard shift and a prompt came on the dash that said reduced acceleration. So as I was passing the vehicle I was pulling in front of them and lost the ability to accelerate or even hold speed. I passed the vehicle got in front of them and slowed down rapidly without any ability to control the speed of the truck. At this point when I would push the gas nothing would happen so I pulled off the side of the road. While we were sitting, there was suddenly a burning smell in the cab so we rolled down the windows and made sure the doors were unlocked in case we had to jump out. We sat there for a minute everything seemed fine I checked the accelerator and it was working again so we drove home. I immediately took the truck down to john watson Chevrolet to have it looked at. I told the service writer what had happened and she said there was a code that had been thrown however there was nothing now and since everything seemed fine I shouldn’t worry about it because the computers trip pretty easily on these new trucks. I insisted on making an appointment so she scheduled me for Tuesday the second of December. I took the truck in just before 730 today the second of December. Christina from john watson checked me in and told me she would let me know when my truck is ready. She called me at 12:34 but I missed so she called again at 1:18 to tell me that she had some news on my truck and that it was going to need a new engine. I took her the dealership rental back and she sent me to enterprise for a 45 day rental. They have had the car for just over two weeks at john watson Chevrolet in ogden utah.

I have three check engine codes p0340 camshaft position sensor a circuit (bank 1 or single sensor) p0341 camshaft position sensor a circuit range/performance (bank 1 or single sensor) p0016 crankshaft position - camshaft position correlation - bank 1 sensor a the last one is the same code that’s involved in the l 87 recall that my vehicle is three months shy of I have a 2021 silverado trail bus 6. 2 l that was manufactured in December 2020 I have very rough idol delayed throttle response in multiple camshaft codes that correlate with the crankshaft symptoms of the l 87 recall.

What component or system failed or malfunctioned, and is it available for inspection upon request? based on information from odi resume ea25007 & safety recall n252494002, it is more than likely engine connecting rod bearing failure. How was your safety or the safety of others put at risk? I was traveling at freeway speed, 70mph when it occurred. Has the problem been reproduced or confirmed by a dealer or independent service center? 11/25/25 at 12:33 (pacific), I am currently stranded 190 miles from home and waiting for the truck to be towed to the dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? it has not. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? prior to failure: since I’ve owned the vehicle, I’ve notice slight ticking and slight knocking during cold start within the engine bay. At the time the noises seemed normal and not cause-for-concern. At time of failure: I was traveling on level grade on the highway when I heard a deep knock from the front, bottom left side of the engine bay. Within about a minute from the initial noise, I received a “check engine” warning light and a message of “esc warning” displayed on my instrument cluster. At that moment, I noticed the engine noise become more prevalent and constant. I immediately slowed and coasted to my next exit off the freeway.

Driving on highway truck lose power, engine lights start to flash and cracking noises start to come from engine. The lose of speed almos cause another vehicle to rear end me, truck gave no signs or warnings before. Truck was delivered to a local shop and due abundant amount of metal flakes in oil engine need to be replaced.

My truck was brought in for the recall inspection for the 6. 2 lt recall. After showing the dealer pictures from the oil that drained out of my previous oil change that was filled with metal, they expedited the inspection. But with substantial amount of metal in the oil filter the truck still passed the test. Gm corporate has told me that once the inspection is done, it is out of their hands and that my truck will be covered under the new extended warranty. Gm also should have the pictures of the metal flakes from the previous filter. I fill like this is a failure to ensure the safety of their product. I do not fill safe having my children or my wife in the truck due to the inevitable of the engine loosing power due to the faulty cam shafts that need to be replaced.
