The contact pulled over and heard an abnormal clicking sound coming from the vehicle before the vehicle stalled.

I have a Chevrolet Silverado 1500 with the 6.2L engine. I received the recall notice about the loss of propulsion due to a crankshaft issue. The safety of myself, family, friends and coworkers who ride with me on an everyday basis were put at risk because of the faulty engine. I brought my truck in for an oil change in August 2025. I had the Team Chevrolet dealership in Las Vegas Nevada do a telescopic inspection to see if my particular engine had the recall issue. It was discovered the engine did have the recall issue and was kept by the dealership for roughly two and a half months. Chevrolet has confirmed this is a major issue and is affecting roughly 600,000 people. There was no sign of the issue before the telescopic inspection but since the engine has been replaced I have now had three separate issues with misfiring cylinders on the new engine. The plugs and wires have been replaced twice and has not resolved the issue. When the misfires have occurred there were error codes, check engine light notification, and engine sputtering. This again has endangered the safety of myself, family members, friends, and coworkers who ride in my truck on a daily basis. This is now going on four months of issues that keep persisting and I am very concerned that both the manufacturer Chevrolet and the Team Chevrolet dealership are not taking the proper steps in order to solve this very serious issue.

The coolant control valve has failed, my vin isn’t a part of the special coverage for this bad part ( though the same part and model is covered)

The engine failed while driving down the road at night in single digit temperatures. After further investigation, there is a connecting rod sticking out of the engine. I looked to see if there was a recall or anything. Sure enough there was. 2021-2024 Silverado 6.2 liter engines for crank shafts and connecting rod malfunction. I'm curious how my 2021 6.2 liter Silverado that has a connecting rod sticking out the side of the block is not part of this recall?

See attached document for complaint.

6.2L L87 V8 engine experienced catastrophic engine failure do to lifter failure and a cylinder 8 misfire. Causing additional damage to camshaft. The dealership has inspected the vehicle and refuses to acknowledge the problem as there own. I have invoices for the work if I choose to proceed. Incident occurred while driving on the freeway, complete lose of power and control. This engine is known for this exact problem yet I never received a recall.

At 46000 miles the motor was replaced because of an internal oil consumption issue after the motor was replaced at 1500 miles the motor locked up while traveling down the road they rebuilt this motor. I went to go pick it up. Drove it 20 miles and oil was blowing out the rear main seal. after this, I sold the truck back to Gwatney Chevrolet and purchased a 2024 model with a 6.2 L I have not had any problems yet.

I own a 2021 Silverado 1500 6.2 v8. Since October of 2025 this truck has been in and out of the dealership. First engine (Oct. 24, 2025) issue as my teen driver was on the expressway and luckily was able to get off and get safely to an unknown persons driveway. Then the motor seized and died as we tried to drive it home. A friend was able to tow it to our driveway and GM sent a tow truck to pick it up and haul to the dealership. The truck was in the dealership for 2 weeks prior to the first engine failure and "EVERYTHING WAS FINE". Nov 26, 2025 new engine comes in. December 12th SECOND motor was put in and FAILED as cylinder 7 had no compression. Dec 31, 2025 picked up my truck with the THIRD motor. Jan 14, 2026 took the truck back AGAIN for engine ticking, noise, loss of propulsion/speed, running sluggish. Dealer kept it until Jan 21, 2026. Dealer said they drove it and the noise is normal injector noise. They did nothing other than drive it. They will not investigate any further as it wasn't pulling codes or warning lights. It is still not running right and I'm waiting for it to have a major failure. It is not safe to drive. The first motor did not show any warnings either. GM really needs to get this figured out soon. No vehicle with 52,000 miles should have 3 motors put in it. This is not quality work and concerns for safety are real.

Lights appeared on dash, brought to the dealership. Dealership states engine damage due to valve train and a remanufactured engine was installed. This was approved by us for a $2000 charge. This charge included new manifolds, water pump, fuel pump and all associated gaskets

I am the owner of a January 2021 6.2 liter Chevy Silverado 1500. I have had multiple issues with this vehicle. Oil pressure control solenoid, many no starts, failure to starts, engine lights, oil lights. Truck started to use an excessive amount of oil before scheduled oil changes. The engine sometimes hesitate and fails to accelerate. The engine became noisy. My mechanic started that the engine is noisy and the oil pressure is at 15 lbs. They said it will need a replacement engine that is not covered under my expired power train warranty. The mechanic stated it's not a matter of if it will go, is a matter of when We are a family of 5 and this is our family vehicle. We feel very uncomfortable driving this vehicle with our family knowing the engine is going to fail at any time while driving. This is a heartbreaking expense that I don't believe that we should have to pay for. We have always maintained our vehicle and have never abused it.

Jan 2024 lifters on one side went out. Towed to dealer and had repaired. 9 months later lifters went out again. Had private shop repair it. Less than 3 months later, motor went out. Paid out of pocket to have new motor shipped and repair shop fixed it. A few months later, GM put out the safety recall for 6.2L engine failure.

The vehicle had originally stopped in a moving lane of traffic. It was towed to a dealership and the engine was rebuilt with a remanufactured engine. The engine idled rough and seemed to be misfiring. The check engine light kept coming on. The dealership stated the vehicle was repaired and I picked it up. The engine is worse. It idles rough like before. It is rough while driving and the check engine light continues to come on. I am about to return the vehicle for the third time before it stops in the roadway again.

Dealer did the L87 6.2 Recall (basically changed the oil to 0w-40). Based on the “clean bill of health” we towed our Imagine trailer to Tucson. Stayed for 3weeks over Thanksgiving and then started back home. We then towed it back home to Fort Collins and when we reached Denver the check engine light came on and within seconds the engine stopped. We had to coast off the freeway and ended up on an interstate interchange ramp (blind and dangerous). The motor was seized completely. Oil pressure and temps were all normal before the engine stopped. Oil was super HOT when I checked it. After a big adventure dealing with getting the truck and trailer to a safe place via a tow from OnStar, they towed the truck to the nearest dealer. I had to rent a UHaul truck to tow the trailer home (another 80 miles or so) with wife, two dogs and myself crammed in the cab. The dealer got Chevy to cover the engine replacement but I was out $200 for the trailer tow to safety and another $200 for the U-Haul rental. Chevy would not cover that.

Warning lights came on at approximately 46000 miles. Brought to dealer for faulty lifters. One week later they decided that the lifters had damaged the cam and now the dealer wants to replace the motor.. Unfortunately for us the dealer has no car that we can use, so we had to rent a vehicle. Hopefully it will be ready in 2 weeks. That will make it four weeks with out a vehicle

I have a 2021 Chevy Silverado 6.2 engine. The recall that has been sent out for most of those engines I have experience the same damage to my truck engine. Connecting rod/ crankshaft engine failure. But my vin is not in the system for the recall. Can someone have a engineer look into more of these engines especially my engine vin. I was driving and all of sudden my dash lite up saying I have reduce steering. Took it to the shop and I was told that my engine needs major repairs. I have a really nice truck and it can be a show truck and for the engine to just go out because of bad manufacturer parts is not right I also had my kids with me. Please help

Most mornings after starting truck and driving off, it appears to be a hesitation or brief loss of power. Issue has been present for several years. It's hard to determine if it's engine or transmission issue. Truck is available for inspection. It usually occurs when leaving house in the morning so there is no safety issue because it happens within the first minute of driving. No warnings, cannot recreate issue.

On 4/19/24 I was driving at highway speed. The engine started to knock and the check engine light came on. I was fortunate enough to be extremely close to my local Chevrolet dealership and made it there before the engine failed. The truck had 38633 miles on it. They found damaged engine components and repaired only the broken parts. Was under warranty. Truck is still ticking to this day. Took it in for this noise and they said nothing was wrong.

Complete engine failure and it just outside the recall. This is unacceptable and needs fixed.

The truck has 61000 miles on it I got it in August there is engine knock which sounds like a bearing might’ve went and now the rod is loose in there. There is a large recall already regarding the same make and model of my truck for this exact issue.

GM 6.2L L87 that was outside of GM original recall engine failure. Engine was running, made loud grinding and squealing sounds then shut off and now engine is locked up.

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

In January 2024, I experienced an engine failure in my 2021 Silverado with the 6.2 Engine. My VIN was not part of the recall affected VIN units built in 2021-2024, it seems to have been built a few months before the last affected group, In any case, I noticed the engine stumbling, and the check engine light came on. I was able to drive the truck home, and when I went to start it the next day, the check engine light was off, so I drove it, and the engine stumbled the check engine light came back on, so I took it to the dealer. They read the codes, and cylinder 5 was misfiring. When they put a scope in that cylinder, the cylinder walls were scored, and there was oil in the cylinder. At that point the dealer chose to replace the engine with a remanufactured engine with no additional warranty added, or any other remuneration for the inconvenience. They did not share with me any specific reason (Lifters / Camshaft / something else) for the engine failure.
