2021 CHEVROLET SILVERADO 1500 Engine Problems

I bought this Truck in December 2023 from Honda of Ocala as a used vehicle it had 59,000 miles when I bought it. In October 24 it started smoking from the exhaust one morning as I was leaving work. I have always changed the oil on time and taken good care of the truck. I found out the lifters had failed and Honda of Ocala replaced all of my lifters on both sides around $4,000 in repairs the truck was at 73,000 miles at this time. A few months after getting it fixed the truck started smoking again and going into limp mode at 81,000 miles. I still owe $30,000 on this truck but can’t afford to keep fixing it and can’t afford to trade it in and go negative on it.

I just bought this truck off a used car lot certified dealer and I noticed the engine light on then the truck would hesitate to start and I know the battery is dying so I looked it up and I got a recall on 2021 Chevy Silverado just like mine just wondering why mine is not under recall or why won’t mine get fixed but everybody else is the same year in the same problems can get fixed. I think mine should be fixed.

Good morning, While driving and starting my Chevy Silverado 1500 with 3.0 durmax it will suddenly go into a “limp mode” reducing speed and power. Recently while driving on a highway it reduced engine power causing the vehicle to slow down suddenly with many cars speeding by. This caused me to try and pull over the vehicle and avoid hitting other vehicles. When pulling codes off the vehicle there is a p1098 which refers to the engine coolant control valve. This will cause the vehicle to do the described power reduction. Upon researching the issue Gm has recognized and released a special coverage to fix the issue. N252508341. However my vehicles VIN does not pull up the coverage. All the characteristics of the coverage seem to fit the model and issues I have. It’s the same year, model, engine, etc. I’ve attached a DOT report of the special coverage. I’m...

Check engine turned on and at the same time the vehicle turned into safety mode abruptly, it slowed down to 10 miles an hour while on the high way and receiving a message stating that the "engine power reduced", the issue was presented to the dealership and they believe to be fixed with a sensor issue, the light came back on a few days after the initial repair and once again the engine lost power while driving the vehicle, the vehicle was then taken back to the dealership for repair once again, both times I mentioned the service bulletin, which they did not consider in their repair, stating that the issue was specific for a code (which all codes present are in the service bulletin) the 2nd repair was done on a actuator, which they stated should fix the issue, and did not, a 3rd time the vehicle lost power...

As I was driving my 2021 Chevrolet z71 pick up I had a warning light appear on the dash indicating the safety traction control system was faulty, at the same time my truck had a loss of power as if it was not operating on all cylinders. I could hear some strange noises that were not normal, at the same time my transmission was shifting abnormally. I managed to drive to a dealer and was told it was a collapsed lifter on cylinder #5 this occurred out of no where, I was informed what took place could have damaged the camshaft and I could be looking at a repair cost upwards of $5,000.00 and the service writer indicated this has been an ongoing issue with the 5.3 liter engine. My truck has been serviced at the dealership it was purchased from, and all oil changes have been performed within a...

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.

Starting back in June 2025 Loss of engine power multiple times. Many times almost hit from behind as I turned onto a highway. Found out vehicle had a stop sale recall at the time of purchase and I had issues with back right tire. Took truck to a tire shop and learned that the wheel was welded in many places and fracture was visible. Finally, got the dealership to pay attention in October to my concerns. They were going to allow me to trade the vehicle out for another one while paying off the bank but that’s not what they did. They attempted the repair and tried to hand it back to me. 1/27/26 Was recently told this was corrected, and the sales person told me when he picked it up from shop he couldn’t go more than 30 mph. Dealership management told him not to tell me. I am...

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...

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...

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.

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.

Component that failed: The valve train system failed due to collapsed lifters in the GM 5.3L L84 engine. The lifter failure caused internal camshaft damage requiring major repair. The failed components were removed by the Chevrolet dealership and should be available through the repair facility if inspection is requested. Safety risk: The engine failure caused a sudden and severe loss of power while driving. The vehicle would not accelerate beyond approximately 45 mph on a 65 mph roadway while en route to the dealership, creating an unsafe speed differential. When attempting to accelerate to pass another vehicle on a two lane road, the engine backfired and immediately throttled back, making it unsafe to complete the pass. The check engine light illuminated at the exact moment the vehicle lost power during the passing attempt. This sudden propulsion loss during an active maneuver created a hazardous driving condition. Dealer confirmation: An authorized...

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...

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.

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

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.

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...

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)

2021 Silverado 19,000 miles no indication of failure at a busy intersection about to go thru intersection and engines started knocking, multiple check engine lights on. Luckily got thru the intersection and to my place of residence which was very close by. Truck was towed to Chevy dealer. Dealer found 3 bent push rods, 3 bad valves. This engine had the lifters fail completely out of the blue. Oil changed at the dealer, meticulously maintained. Dealer only replaced the faulty bank of lifters due to mileage, seriously if it was under 16,000 they would replace all of them. This is unacceptable. This truck left me almost stranded in a busy intersection, lucky I knew well enough to keep going versus getting T-boned. I just think GM needs to do something about this. Now fast forward to 41K and I'm at the dealer same symptoms except this time my warranty is...

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?

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.

Throttle Body Failure Anti brake lock failure Throttle position sensor failure Power reduced *Vehicle has been to repair shop 3 times and the issue prevails. It poses a risk to my community because my loses power sporadically*

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...

August 30th 2024 the pickup was just turning to roughly 30,000 miles and started a knocking sound. The GM dealership tore it apart and fixed what I believe they said was a bent rod. I cycled through two oil changes and decided to pull an oil sample. I sent oil sample off for analysis. The oil analysis came back urgent with very high levels of copper and lead showing in the testing. I then called the GM dealer and they had me bring it in. They did not send off any oil sample because when they pulled the filter, they could already see metal in the new oil. They had me call GM customer service because it is not part of the current recall. I contacted GM customer service on October 27, 2025. They gave me a case number 80392504. I was to bring it back to the dealership which...

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.

Vehicle experienced engine failure while driving. Loss of power in traffic. Inspected by dealer and determined to have lost compression in cylinder #5. Initial inspection determined that lifters and camshaft would need to be replaced. This issue is the same common problem with this year model (2021) Chevy Silverado Trucks as noted in TSB #N212353840. At time of purchase dealer did not notify me that these trucks were experiencing these issues nor did they complete the suggest repairs prior to the sell as described in the TSB.

My engine on my 2021 Silverado 1500 with the 6.2L L87 engine failed, I took it to the dealer to repair and they quoted $4500 to fix it. I know these same engines are being recalled and GM is having to replace them, but they told me mines not one of the ones being recalled and the won't cover it because the warranty was up 5,000 miles ago. I highly doubt it's a coincidence, that mine failed after only 65,000 miles and it's not a manufacturer flaw. The vehicle is currently at the dealership awaiting repairs.

engine is knocking very bad. GM Dealer says it is an issue w/ the piston main bearing and the engine needs to be replaced. Says vehicle should not be driven.

I was driving on big highway when I lost power brake light came on engine light on message about emergency brake need it serviced I was only able to go about 15 mph on big highway very dangerous engine sounds knocking was very loud at this point I knew something very bad happen my truck only had about 85k miles on it I took to the dealership to get a diagnose they took my oil filter off and found metal debris on it and told me I need a new engine I has to know what made this engine fail but they just told me a internal part fail well I was not happy with that answer knowing that some model truck with the v8 engine where having problems with valve body’s my truck is 4 cylinder turbo 2.7. My truck is out of warranty I call gm and told...

GM 6.2 engine recently tested for the national recall regarding valve and lifter issues. Recall was cleared as ok, but they found burnt cylinders in multiple areas within the engines. Several issues are still occurring with this engine, and I think most are related to the recall effort. 1. Engine will use oil at an abnormal pace when towing anything heavy. Recently used an additional 2 quarts of oil when towing a trailer that weighed 10, 000 pounds over 1600 miles. 2. Recently engine seemed to lose compression at a stop light and turned off. This happened an additional 5 times until I could get the truck off the road and into a safe place. The engine would immediately start and then die within 5-10 seconds. Towed to a Chevrolet dealership and the service manager tried to move it into the bay for diagnostic testing. started and stopped 4 additional...

Vehicle was at a stoplight with the auto start button engaged on it. The vehicle completely stalled. All the power is drained from the car. leaving me stranded in the highway. I got it towed and when replacing the battery still nothing will roll over or even turn on.

Engine just died going 55 mph on a paved road. GM repair shop says engine needs to replaced. They originally told me my 6.2L engine was a recall, but my VIN didn’t show on database. Seems GM’s scope was not wide enough on their recall. I feel I deserve a new engine.

Started with a clicking noise that mechanic thought it was the fuel pump but found out later it was the bearing is the rocker arms that failed and ruined the camshaft. Now it needs a new engine.

2021 chevy silverado Engine was under the 6.2 recall On Sept 4 2025. The engine blew and the truck was taken to local chevrolet dealer. It had 38k miles on it. It stillf ell under the original powertrain warranty and the recall. Dealer informed me new engine was needed and ordered. It has been 2 months and the engine has not shipped from GM. 60 days is more than adequate time for this issue to be resolved. GM has made no attempts to make this right. Please help

misfire on cylinder #6 lifter failure on cylinder #6 bent push rod on cylinder #6 happened going down the highway at 75mph, luckily no one was injured local Chevrolet dealer did diagnostic and repairs repairs were covered by aftermarket warranty - $100.00 deductible no warning lamps or messages or other symptoms before hand

Dealer says my vehicle is not approved to even check the motor out. Build date 6/21 6.2l motor under recall

Engine failure in 2023. Paid 15,600 to have engine repaired and gm is denying reimbursement because repairs not done at dealership and vehicle is too old is what they are giving me for reasons for denial.

I’ve purchased my Chevy Silverado brand new and I’ve had to bring it to the dealership multiple times for code P1098 this will be the second time this has been repaired. Looking on line this is very common. This is the second time I have to leave my vehicle at the dealership and not I don’t have my vehicle.
