Engine And Engine Cooling Problems of Chevrolet Silverado 1500 - part 1

I have a 2021 Chevrolet Silverado 1500 with a 3. 0 duramax diesel engine, have had a check engine light intermittent a couple times. Vehicle went into limp mode. Had the diagnostic code read; p1010. Code p1010 shows an engine coolant flow control valve position sensor exceeded minimum learning limit. General motors has issued a special warranty n252508341covering 2021-2023 Silverado 1500 for this part ( lm2 coolant control valve replacement ) with a 15 year and 150,000 mile limit. I took my vehicle to the Chevrolet dealer and they said my VIN number was not covered. It would be a $1900 repair. I have read of numerous other of same vehicles listed under the special warranty, yet gm has excluded these VIN numbers as well. This is a known defect, gm has covered some but not all. Yet many are not covered yet having the same problem. I am not able to reach anyone at gm to talk about this issue. It needs to be addressed.

Truck continues to shutter after having the torque converter replaced and the 2nd injector replaced. Been in the shop several times over the last few years, and still giving warnings on the dash saying, reduce acceleration drive safely. Feel like we just got a terrible vehicle. Almost paid off, and it’s just unreliable. Sadly we need this truck every single day, and the local dealerships have now pushed the problem out so far that we’re passed out 60k warranty period.

While driving my truck returning from a camping trip I received the following warnings in the dash: service esc, service traction control, forward collision system unavailable. Check engine light was flashing. I made the assumption that the check engine light was due to the warnings listed above. I continued to drive the vehicle until I began to feel a very noticeable shudder at idle, at low speeds, and also loss of power at higher speeds. The truck has the 5. 3 ecotec engine with dfm. After researching the symptoms, I found that these symptoms are identical to the know lifter problem with that engine. The truck is a 2026 Chevrolet silverado trail boss with approx. 3454 miles on it. It's currently at the dealership waiting for them to "diagnose" the problem. I was told that it may just be a "faulty sensor", but after reading other people's experience with this engine I believe that the real problem is a damaged lifter/lifter pin due to the poor design and engineering of the dfm system.

A valve on the 3. 0l duramax is allegedly sticking, causing the vehicle to go into limp mode or be inoperable. This is a known issue for gm and they have issued a service bulletin on it. Unfortunately, no dealers want to address the issue and now we are left with a vehicle that if we do not pay to repair, after it being ours for only 5 days, the vehicle will be unusable. This vehicle is under warranty still and this part is needed for operation. I believe this avoidance of a recall is harming customers and creating pay to drive schemes. This needs to be addressed before thousands of customers begin paying for a repair that gm knows is their fault.

We purchased our 2022 Chevrolet Silverado 1500 zr2 in xxx, it was discovered in the purchase process that the vehicle had an active recall on the engine which was pending a "fix. " this was completely downplayed by the dealership as a minor issue that would be addressed. We waited several weeks for the "fix," which was essentially a change in the oil viscosity. On xxx, our [xxx] son, was out of town, driving the vehicle, which suddenly lost all power on the highway leaving him completely stranded. The vehicle would not turn over at all or even shift into neutral. There were no warning signs, no sensors activated, in fact, the chevy app showed (and still shows) the vehicle as "everything looks good" "no diagnostic issues!" we had the vehicle towed back to our hometown/dealership (missoula, Chevrolet in missoula, mt), where it has now been determined, the engine completely seized up/failed, the original "fix" was not adequate, and we are now waiting for a new engine to be put into the vehicle! after reading about other vehicle owners experiences, I am quite skeptical of the new engine as there have been multiple experiences where the new engines had the same issue. This recall is impacting the safety of drivers, most concerning was our [xxx] left stranded in a rural area with very spotty cell service, and the vehicle would not even shift to neutral to get it to a safer area, this needs to be addresses as soon as possible to prevent others from being put into this situation.

This incident occurred 24, June 2024. Time was approx 1745hrs and temperature was 93 and humid. Was stopped at a stop sign, attempted to make a phone call and reached to temporarily turn off the air conditioner by pushing the on/off button. When I pushed the button, it turned off the vehicle engine completely! when I was startled as to what had just happened, I pushed the air conditioner button a second time; it started the truck's vehicle engine! I repeated this test three times in the presence of my spouse who was also in the truck. We then drove approximately one mile and at a second stop again was able to duplicate the engine turned off/on by pushing the air conditioner on off again! it was if the air conditioner on/off button was the vehicle start stop button. I did not try to duplicate this under roadway speed, fearing if the engine did in fact turn off, simply by pushing the on/off air conditioner button. It would most assuredly result in the complete loss of driver inputs for steering, brakes and control.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving approximately 50 mph with his wife and grandchildren inside the vehicle, the check engine warning light, collision warning light, and several other unknown warning lights were illuminated. The contact stated that the message "braking system failure - do not exceed 62 mph" and the trailer brake message was displayed. The contact continued to drive the vehicle; however, whenever the brake pedal was depressed, the vehicle failed to slow as intended. The vehicle was taken to a dealer where it was diagnosed and determined that a software update was needed. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 54,000.

Date: June 22, 2026 time of incident: approximately 11:48 a. M. Vehicle: 2025 Chevrolet silverado high country 6. 2l v8 current mileage: approximately 29,500 miles I am documenting the events surrounding the unexpected engine failure of my 2025 Chevrolet silverado high country. On June 22, 2026, at approximately 11:48 a. M. , while driving at highway speed, the vehicle was operating normally with no warning lights, messages, or other indications of a problem. I began hearing a metallic clanking or knocking noise from the engine area. The noise progressively increased in volume and severity over approximately ten minutes as I reduced speed and looked for a safe location to pull over. My intention was to reach the dealership if possible; however, as I slowed to approximately 15 mph to make a turn, the noise stopped abruptly, the engine shut off, and the vehicle displayed a message instructing me to press the start button again. The vehicle came to a complete stop at approximately 11:58 a. M. I attempted to restart the vehicle once, but it did not restart. No additional restart attempts have been made. There were no warning lights displayed prior to the engine shutting down, and there were no visible fluid leaks underneath the vehicle after it came to a stop. The vehicle received a routine oil change on June 16, 2026, approximately three days before this incident. I have retained the service receipt and all related documentation. The vehicle will be transported by flatbed tow truck to an authorized Chevrolet dealership for diagnosis and repair under warranty. This email is intended to document the incident timeline and details while they are fresh in my memory. I have not heard back from the dealer yet.

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.

My company purchased a new 2022 Chevrolet silverado rst from bomnin Chevrolet manassas in December 2022. The vehicle has been properly maintained according to gm’s recommended maintenance schedule, including routine oil changes and tire rotations. On February 10, 2025, the truck began shaking and repeatedly shutting off. Bomnin Chevrolet diagnosed a failed fuel injector and completed the repair. No loaner vehicle was available, requiring me to use uber transportation until the vehicle was returned on February 12, 2025. On may 19, 2025, the truck again shut off multiple times while traveling approximately 45 mph. The vehicle was returned to bomnin Chevrolet, where it remained for three days. No loaner vehicle was available, forcing me to rent a vehicle from enterprise. The dealership ultimately stated it could not diagnose the problem and advised that the failure would have to occur again before it could be repaired. The vehicle was returned on may 22, 2025. On June 18, 2026, the engine shut off while driving and would not restart. The vehicle was towed to bomnin Chevrolet. After several days, the dealership advised that the engine had suffered catastrophic failure due to a lifter issue and required complete replacement. Gm approved the warranty repair; however, the replacement engine is on national backorder. No loaner truck was available. The dealership offered only a $44-per-day rental reimbursement, which is not comparable to the business use of a full-size pickup truck. As of June 29, 2026, the vehicle remains at the dealership, leaving my business without a suitable replacement vehicle and significantly impacting daily operations. I am requesting a voluntary manufacturer repurchase of the vehicle, reimbursement of all rental cars, and a fare financial compensation package for any inconvenience.

I am requesting immediate review and resolution regarding a major engine failure in my 2021 Chevrolet Silverado 1500 with the 6. 2l v8 engine. My vehicle has suffered a complete engine failure and is displaying code p0016 (crankshaft/camshaft correlation). This is a known and widely documented defect affecting gm 6. 2l engines and is the basis of an existing recall and engine replacement program for similarly equipped vehicles. Despite my vehicle exhibiting the exact same failure, I have been informed that my VIN is excluded from the recall. This is unacceptable, as it reflects inconsistent application of a known defect remedy. Under consumer protection principles, including the magnuson-moss warranty act, manufacturers are obligated to address known defects and ensure consistent warranty and post-warranty remedies where systemic issues exist. Denying coverage for an identical failure based solely on VIN exclusion raises serious concerns. I am formally requesting a full goodwill engine replacement. This failure is clearly tied to a known defect pattern, and I expect gm to provide the same remedy afforded to other affected customers. Please escalate this case for immediate review and confirm next steps. I am prepared to provide all supporting documentation.

Check engine light flashes when pulling a load and accelerating above 50mph. Check engine light code is po300 random multiple misfires. Took it to the shop and there we’re currently no active misfires.

Service brake assist warning came on the day before a severe audible engine knock started. Drove to nearest dealer and they immediately diagnosed as a probable engine failure/engine bearing/connecting rod. 6. 2 liter engine 9500 miles.

On Monday, 6/15/26, with approx 45,400 miles, I was driving down the road and truck said service transmission. The gears would shift, but it lagged a little bit. I scheduled an appt for two days later, and only drove it when I absolutely had to, which was only twice before my scheduled appt. I get in it to drive and it says service transmission- unable to shift soon, then on my way to the dealership, it says all of that, plus service driver assist system. Chavy's quality assurance team needs to get it together! this is absolutely ridiculous.

My truck has the l87 motor on recall. I purchased it brand new and paid top dollar for it. I've had issues since I've bought it. All of my maintenance has always been done at the dealership from regular maintenance to purchasing brand new tires. I am very disappointed to have a truck that concerns to drive, I do not take my family out in my truck because I am not confident in its reliability and safety. Multiple times I've taken my truck in for service and let them know to complete an oil change, tire rotation and to check an issue with a "tick, clunk and knock" just to be told it was "normal for the 6. 2". My normal dealership has blocked off appointments online and you'd have to call to try to set one up. I demanded a diagnostic one time when the truck was acting weird and the tech stated "stop by, I'll squeeze you in" in which I did. However, I wasn't given any documentation since "I didn't have an appointment". After reviewing all of my service records, I come to notice not once time did they mention they did a diagnostic check. Only the recall test shows on one of the service records. I've had 3 different viscosity oils in my motor from the dealer stating gm recommended it. I had to night drop my truck on June 14 as it was making a weird noise from the engine and it felt like it had less power. I waited 2 days and the dealer did not contact to even state they have my truck in service. When I called to ask the status I had to agree to text message communication in which they replied, "at best it will take 2 weeks just to look at it". I asked for a loaner since I need a truck for work and transportation, they replied they do not have any and I will be placed on a list. My truck is still under original powertrain warranty and they cannot even provide a loaner. I feel that they are brushing me off to buy time and here I am making hefty car and insurance payments for a truck I do not have nor a truck that I need to provide for my family. Gm does not care!.

Purchased 2019 Chevrolet silverado high country edition with the 6. 2l engine and 143k miles for my son. The vehicle had a clean service history on car fax. On the day we purchased the vehicle, we drove it home and noticed it was shuttering at times. I used my computer scanner and it came back with a misfire cylinder #5. I troubleshot the issues and noted that the most common thing was a spark plug. Therefore, I replaced the spark plug and it drove much better. Two weeks later, my son was driving vehicle on I-40 near nashville TN and without warning, vehicle stalled, locking steering wheel in place! check engine lights came on and instructed him to place in neutral and restart, which he promptly did. The vehicle started, but went in limp mode making loud noises in engine before shutting off again. Luckily, traffic was minimal at 8 pm and he was able to get it over to the shoulder and avoid any injuries or accident. Towed it to nick mayer Chevrolet in dickson, TN where they diagnosed it with catastrophic engine failure and needed to be completely replaced. This is the same issue that gm is being sued for and have somehow managed to take the stance that the lifter/cam/dfm issue only existed in 2020-newer models. The 2019 is when they changed to the newer body style and the new gen v l87 engine in the 6. 2. Despite the clean vehicle history, dealership reached out to gm and they stated they would not help cover any repairs but would gladly take 14k to fix it. The 2019-2026 models all need to be recalled due to this safety issue and fixed before catastrophic engine failure claims another victim financially or worse!.

Recall remedy was performed just a few months prior didn't even make it through the life of the oil and the 6. 2l l87 is seized up per Chevrolet dealership in chelsea michigan.

Leased a 2025 chevy silverado in late 2025. On June 13th 2026 driving home my vehicle all of a sudden had very little power, check engine light went on and thankfully I was at my driveway. Pulled into my residence, shut truck off and called the dealer I leased the truck from at 1:00 pm satuarday, June 13th. They set me up with a loaner vehicle. I called for a tow truck Monday the June 15th and had truck delivered to dealership. Ive been told, they are looking into? beyond that, nothing more.

Over the last week, my truck power has been almost shutting down after the stabilitrac warning appears on the dash while I’m turning or going over uneven pavement. The whole system shut down once already when turning around in a driveway. I have a new battery. Spark plugs are good. Abs is good. There are no recalls I can find, but this must be electrical somehow. Help me pls before it causes an accident.

When on the highway and attempted to accelerate to pass in the passing lane, there was a loud pop, the truck rapid decelerated and my son was forced to drive off the burm to avoid being hit by a semi truck. It’s been determined that it was caused by a lifter failure due to the afm system.

6/12/26 ( 2023 chevy silverado - 6. 2 liter engine) while driving at approximately 40 mph on a two lane road, the truck shut off. After multiple attempts, the engine failed to restart. The transmission locked up in park and would not release. This required the truck to be dragged up on the flat bed wrecker instead of rolling freely. Prior to this instance there have been several issues with the electrical system. 1. Radio sound shuts off. Does not come back on. 2. Head lights stay on for 10 minutes after vehicle is turn off. 3. Tail gate opens on it own. Tail gate doesn't open with fob. 4. Door locks fail to operate correctly. 5. When drivers door is opened a beeping sound starts and doesn't stop until door is closed. I have reported these problems to gm & have two case numbers. The dealership reports that the 6. 2 replacement engines have had multiple failures.

6-12-26 while driving down the highway the engine suddenly started running rough. Multiple warning lights came on and sounded like a muffled backfire. The truck has confirmed lifter failure as well as camshaft damage enough to where they're replacing an engine I still have no eta on getting my truck back the truck only has about 72 or 73,000 miles.

Took my 22 silverado with the l87 engine in for the recall. The dealer stated that my vehicle had a tick in the motor but it passed the pico test. They switched it to the 0w40 oil and stated that my engine will probably blow here soon, but until that happens there hands are tied. Today I took my truck in for another inspection because my motor had a very loud tick noise almost sounding like metal on metal, they stated they did not hear anything and without more proof nothing can be done. My safety is very much put at risk when I report something to them thats happening with the vehicle, and if my motor blows while im driving 80 mph I could crash into others or even die myself. My transmission is also having problems of what I would call bucking when you put it into drive, I also filled up with gas last week shut my truck off pumped gas, got back into my truck and started it, went to put it into drive had no power shut it off and did it again, I had power but my rear wheels were locked up and wouldnt budge. Shut it off turned my truck on and engaged the 4 wheel drive, and then disengaged it, still not able to drive. Shut it off and put it back into drive and the rear wheels were able to drive normally. Dealership says theres a recall on the transmission to add a spacer plate so it was ordered. This issue needs to be taken very seriously this is why they say theres only 3% motors affected is because they decline the motors that have actual problems but its still running so to them its fine.

Engine light came on and off and June 10, 2026 the truck just stole and no power to go.

Auto wash truck quit, dead would not restart, tow service disconnected battery and reset. Okay after. Visit to dealer service they said nothing wrong. Driving yesterday in the rain quit 4 times on the road driving, it would restart each time. Warning on the dash would flash at times "hands on the wheel" while driving ? this is a serious safety issue. Intermittent when it gets wet, new truck, 1,800 miles, no alterations. Dealer service no help, it has hard codes, can bus communication issue, water intrusion likely cause, we are afraid to operate on the road, help please.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving 25 mph and attempting to depress the accelerator pedal, the vehicle lost motive power, the contact attempted to start the vehicle, and the vehicle operated as intended. The check engine warning light was illuminated. A dealer was contacted. The vehicle was taken to a dealer to be diagnosed; however, the diagnostic result was unknown. The dealer cleared the codes, and the vehicle was then taken to another dealer, where it was diagnosed and determined that the ground strap needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the part was on back order and might take six months for the part to do the repair to be available. The approximate failure mileage was 4,000.

Verified customers cpncern of cylinder 3 misfire and low compression. Inspected cylinder 3 sing a borescope and found excessive oil on top of the piston and on the cylinder walls. There are marks from loose carbon debris damaged the cylinder wall. Upon further inspection the oil looks to be coming from the valve seals. Recommend replacement of the long block assembly to correct these conditions. --cody glasscock, Ford Lincoln of morgantown.

The truck started backfiring and shuddering. Took it to the mechanic and with only 112000 miles I am being told it needs a new engine. It is the 6. 2l motor.

Engine failed and no light or warning besides check oil was shown on truck. The electrical system also went out (a year before engine failure) so car wouldn’t start.

Was on way to trade truck in onb6/6/26 and got a cylinder #7 misfire. Replaced spark plug and wire and moved coil packs around to trace and stayed on #7. Just had recall completed on 9/25/25 and stated that I've heard a rattling noise in engine area. They performed recall and changed to new oil suggested by gm. Dealership said noise was transmission. I told them that was replaced already within last 50k miles under warranty. Drive it for a few days and rattling noise still there. Took back to dealer on 9/30/25 at cost of $200 diagnositc and stated there is a grinding noise under light acceleration like it's metal on metal. Dealer stated that it was the rear seat rattling. There were no noises in the cab, only coming from outside at driverside motor area. Called gm 10/1/25 to let them know the denial of motor replacement and we wanted 2nd opinion but we would have to pay out of pocket again. On 6/4/26 had to have truck towed to new dealer. New dealer won't make deal on new truck because of this and we have 2 trips already booked and paid for and 1 at end of June. New dealer is putting in service on 6/8/26 to verify cause. I have called gm after making repairs and they said it was between me and the dealer, there is nothing they can do. This is unacceptable! im fine if they would offset cost and buy a new chevy truck and we are going to fight to get it made right. This does make us want to change brands even though we've bought 5 chevys in the last 10 years.

Low engine oil level appeared on my 2022 silverado ltz with the 6. 2l engine for the first time of ownership. The truck is on the first 0w40 oil change performed for the engine recall with 42% engine oil life left. I get the oil changed around 30% left. Up until this point while running the 0w20 this hasn't happened. I'm now concerned that because of the oil viscosity difference that this may become an on going issue.

While driving my truck it started flashing all the service lights on the dash, and then started shaking bad and making a loud ratcheting noise from the transfer case/transmission and a loud knock/tick from the engine. I scanned for codes and it has all loss of communication codes for engine/transmission/transfer case/brakes/steering.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving, the vehicle failed to exceed 6 mph. The check engine warning light was illuminated. The vehicle was taken to the local dealer, where it was diagnosed and it was determined that the abs module needed to be replaced. The dealer had retrieved dtc: p2074. The vehicle was repaired, but the failure reoccurred. While driving in stop-and-go traffic, the vehicle failed to accelerate and unexpectedly shifted into park(p). The contact stated that the vehicle failed to restart, and the battery was disconnected and reconnected. The vehicle was then taken back to the local dealer, and additional diagnostic tests were recommended. The contact was informed that the torque converter and transmission needed to be replaced. The vehicle was taken to an independent mechanic, who stated that the failure was related to technical service bulletin: 23-na-018. The manufacturer was contacted and informed that the dealer should use a flow chart. No assistance was provided. The failure mileage was approximately 100,000.

2022 Silverado 1500 ltz w/6. 2l 38082 total miles. First engine replacement due to seizure at approx. 17,782 miles around June/2025, the vehicle lost all propulsion and stopped running while sitting at a stop sign at a four way intersection during a really bad thunderstorm, luckily the intersection was on a declining hill and I was able to coast it into nearby parking lot . I'm a senior citizen with a replaced hip and couldn't have gotten it out the roadway otherwise. Contacted gm through the app. To arrange service and tow. The tow couldn't be completed by the assigned wrecker service because it was busy with other tows because of the severe storms. The following afternoon, it was towed to the local dealership for service. It took approx. A week before I was finally informed that the engine seized with explanation. . Repair took just over 3 months to complete under warranty/recall at dealership, didn't get vehicle back until the beginning of September 2025. Engine replacement inspection passed by GMC on the recall inspection at local dealership. Oil changed from factory 0w-20 to 0w-40 around January or February 2026 if I'm not mistaken. Driving down the highway on 06/03/2026 and all the sudden loss of propulsion. Zero warning! lucky I was able to coast onto an exit ramp without getting in an accident with hwy. Traffic! luckily I was able to find a church parking lot and asked a person that I knew to give me a ride home. Because it was after business hours, I waited till the local dealership opened the next morning and spoke with service personnel and they arranged a tow to take it to the dealership. As of the end of the business day 06/05/26 I have no word from dealership on the status of vehicle, but the vehicle experienced the same symptoms, a sudden total loss of power and no start, just a single click and no electrics. I feel that the inspection testing and oil change does not address and/or fix the root cause of these engine failures.
