2021 Chevrolet Silverado 1500

On June 22, 2026, my Chevy Silverado was inoperable and had to be towed to the Chevy dealership. After a period of examination by the service staff, it was deemed to have experienced CATASTROPHIC ENGINE FAILURE. My truck has the 6.2L engine, but was NOT included in the original recall. It had just been serviced on 6/19/2026 and was only driven approx. 20 miles to my home. I have a video of what it was doing when I went to leave for work two days later on 6/22 when it wouldn't run without major issues and a burning smell.

An engine lifter broke in my 2021 Chevy Silverado 1500 (6.2 liter) and it bent a push rod. The truck was towed to the dealership where it was purchased. They replace all the lifters on the failed side and the bent push rod. The reason I am reporting this is because it happened at a very unfortunate time and could have resulted in a major accident if the engine would have seized. I was turning a corner, crossing oncoming highway traffic, and pulling our camper/travel trailer. I see that it has been a relatively common problem with the GM 6.2L and even some 5.3L motors and appears to be related to GM's active fuel management (AFM).

Loss of engine power while merging or passing traffic. * Reduced acceleration making it difficult to enter highways safely. * Engine overheating if the active grille shutters fail in the closed position. * Unexpected limp mode causing sudden speed reduction in traffic. * Increased risk of a rear-end collision due to loss of power or reduced speed. * Check engine light and warning messages distracting the driver. * Vehicle stalling while driving or at intersections. * Reduced visibility if the defroster or HVAC performance is affected by engine temperature issues. * Potential engine damage from overheating, creating a hazard if the vehicle becomes disabled on the roadway. The active grille shutter system malfunctioned and caused warning lights to illuminate. I am concerned that the shutters remaining closed could lead to engine overheating or reduced vehicle performance while driving, increasing the risk of an accident due to loss of power or unexpected vehicle behavior in traffic.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the message that the rear seats were occupied and that the windows were rolled down was displayed, which required the contact to press the OK button. The vehicle was taken to the dealer where it was purchased, but no assistance was provided. The traction control and the ABS warning lights were illuminated while depressing the brake pedal. Additionally, the cruise control mode was inoperable. The contact replaced the brake pedal position sensor independently, and the vehicle was taken to an independent mechanic, who reprogrammed the sensor. The contact stated that after the repair, the brake lights erroneously illuminated while the vehicle was turned off, causing the battery to drain. The contact disconnected and reconnected the battery, which reset the vehicle; however, the failure recurred. The vehicle was not further diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 110,881.

A tire purchased new as part of a complete set failed on June 29, 2026, approximately 58 days after purchase. The vehicle was being driven on a smooth road surface under normal driving conditions when the tire suddenly failed. There was no known impact with a pothole, curb, road debris, or other road hazard before the failure, and there were no warning lights, messages, or noticeable symptoms indicating a problem with the tire before it failed. The sudden tire failure created a serious safety concern because it occurred while the vehicle was being driven and could have resulted in loss of vehicle control, a collision, or injury to the vehicle occupants or other motorists. Because the failure occurred while traveling out of state, the tire was taken to an independent tire service center for inspection. After inspecting the failed tire, the service center documented that the tire had separated internally and determined that the failure was due to a manufacturing defect. Written documentation of the inspection findings was provided. The failed tire was later taken to the selling Goodyear location for inspection. Goodyear disagreed with the independent inspection and claimed that the failure resulted from a pothole impact. No pothole or other road hazard was struck before the tire failure. The failed tire has been retained and remains available for inspection upon request. The independent service center’s written inspection report, photographs, purchase documentation, and other supporting records are also available. 275/65R18 116T

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.

Vehicle experienced sudden power steering failure and needed to be towed. A list of preceding error codes presented upon diagnostic review including power steering motor circuit, control module power circuit low input/low voltage, steering failure mitigation, power steering malfunction, lost communication with power steering control module to name a few. Dealership traced it back to a known GM part issue with the body to chassis ground strap identified in GM consumer satisfaction program N252515590 in Chevy and GMC 1500 2019-2024 models. The identified strap corrodes causing electronic failure noted above and documented by the dealership. The CSP was issued in January 2027 and is in effect until February 2028 however the dealership charged my out of pocket $384.48 for labor for a $13.40 part. My GM platinum protection plan also refused to cover the cost of the know defective repair.

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.

My 2021 Chevrolet Silverado RST 4x4 5.3L V8 was a Certified Pre-Owned vehicle purchased through a GMC dealership, strictly maintained by certified GMC service departments, and had its torque converter replaced one year prior in accordance with a manufacturer Technical Service Bulletin (TSB). One week before a scheduled round-trip journey from Alabama to North Carolina, the truck underwent a comprehensive multi-point inspection, oil change, and tire rotation at an authorized Chevrolet dealership. While driving on the highway, I came to a complete stop due to an accident ahead, but when traffic resumed a forward-moving pace, the drivetrain completely lost the ability to propel the vehicle without any prior warning signs or symptoms of mechanical failure. While immobilized and contacting 911 and towing services, I attempted to cycle through all drive modes—including Auto, 4-High, 4-Low, and 2WD—but none succeeded in transferring power to the wheels; though the engine would still rev, no power reached the tires. No dashboard warning lights illuminated prior to the drivetrain failure, though a check engine light did appear after the vehicle became immobile when I was switching through drive modes. Because there was no available highway shoulder or exit to seek safety, and due to the sudden nature of the mechanical failure, emergency vehicles and tow trucks could not safely divert traffic or move the vehicle in time, resulting in a severe rear-end collision that caused a total loss. The vehicle has not yet undergone a mechanical inspection, but it is currently under a 60-day hold for examination by insurance adjusters and legal counsel, and it remains available for a formal teardown upon request.

I bought a 2021 Chevy Silverado 1500 Badlander edition in February of 2025. I love the truck and drive it everywhere. I have brought it in for every oil change when needed. I got my first oil change April of 2025 and had no issues. Then I got my second oil change June of 2025 and both of these were done at the dealership that I purchased the truck from. At the June oil change I asked Jeff Belzers to do an oil consumption test and they said they would not because my vin did not show up in the recall. On July 31 of 2025 I got an engine oil low light on my dash, which I took a picture of. At that time I had to add two quarts of oil. Then in August of 2025 I went in for my oil change at Jeff Belzers again and I told them about adding the two quarts of oil and asked again at that time if they could do an oil consumption test and they told me no again because my vin was not on the recall list. I then got another low engine oil light on September 29, 2025 and at that time I added 2 quarts of oil. In October of 2025 I brought my truck to Maur Chevrolet for an oil change and asked them to check my vin for a recall and they said there were no recalls. Then I brought my truck to Maur Chevrolet in November of 2025 for an oil change and I asked if the vin recall had changed and they said no. At this time I was just checking my oil and adding as needed. I took my truck in for an oil change in January of 2026 and asked about the recall again and no changes. Then after that oil change, I was adding a quart of oil every 600 miles. So when I went in for an oil change in April, I asked for an oil consumption test to be done and the service advisor said yes. This was the first positive step I had in this entire ordeal. At the end of the consumption test, which was on June 12, 2026 it was verified that the engine was burning 3 1/2 quarts of oil every 3,000 miles. At that time I had another oil change done and they told me that they would discuss what would happen on Monday June 15, 2026

When i first purchased the vehicle off the lot a few years back (its a 21, so probably in 22?) Brand new off the lot minimal miles. Within the first few months we started having issues with the power wanting to shift down. We took it in, the dealership found nothing wrong with it and cleared the codes. This happened a few more times. The last 2 times I took it in. They mentioned that there were recalls on it and could possibly be causing the issue. Took care of that (last august- have docs. to prove it as along with what they did and what we stated). Fast forward now 2 months ago (April of 25) and it starts acting up again and wants to downshift, shifting hard, stuttering and not wanting to drive, the same things we have been complaining about since beginning with lights on etc. However, this time we tried to shut it off and give some down time to get back home. After about 10 mins, we went to start the truck to get it home, and it would not start. We had it towed to the dealership. Once they got it, after 2 weeks of waiting we were finally presented with, the starter went out and the wiring box needed to be replaced (this has to be done before they can look into the original problem again) (because without those 2 things fixed, they wont be able to do) it is now June. I took the vehicle home, due to not having funds to fix right away. After doing some research and some digging, it would appear that the issues that we are having with the truck are issues that are already being recalled on this specific truck and model. However, for mine it is not, because I have the 2.7 l turbo and not the 6.8. THere have been numerous complaints about the known issue.(which i found out is the other wiring by the engine that is being chafed which is causing the wires to break and causing the other box and alternator to go and be replaced). If you replace it fries all again. Why is the 2.6 engine problem thats reported not recalled but rest is and it is known. I also see this online

On June 3, 2026, my 2021 Chevrolet Silverado 1500 LT Trail Boss, which has a 6.2L L87 V8 engine, stalled and shut off unexpectedly while I was stopped at a traffic light on a public highway. The engine died without warning, leaving me stranded in traffic and creating a serious safety risk for me and other drivers because of the chance of a collision. I had to call the police to come and sit behind me to keep myself safe from a collision while I waited for a tow truck. A dealer diagnosed the vehicle with DTC P0016, indicating a crankshaft/camshaft position correlation fault. This points to either an engine timing problem or an internal engine failure. The dealer confirmed the issue and gave me a repair estimate of about $11,000. Both the vehicle and repair records can be inspected if needed. Before the failure, the vehicle showed signs of an engine timing or internal issue and eventually triggered the check engine light with code P0016. After researching, I discovered many reports from other owners with the same 6.2L L87 engine who faced similar problems, including P0016 faults, engine stalling, internal engine damage, and complete engine replacement. While some vehicles with this engine have been part of recalls or special coverage programs, my vehicle is not included, even though it shows the same failure pattern. At the time of the failure, the vehicle has about 140,336 miles. I believe my vehicle has the same defect affecting other 6.2L L87 engines. I ask that NHTSA look into whether more vehicles should be added to any current or future recalls or defect investigations. Thank you for your attention to this matter.

I have fighting this issue since January and have not gotten any help or relief from Chevrolet. This issue caused a significant safety risk and has cost me $12,000. I am writing to formally report a serious safety issue involving my 2021 Chevrolet Silverado that resulted in a sudden loss of power while merging onto an interstate highway. On XXX, I brought my vehicle in for service to replace the upper and lower ball joints, as well as the control arms. I retrieved the vehicle from the repair shop on XXX, and departed the same day for travel to [XXX]. Later that evening, while traveling southbound on [XXX] near [XXX], I stopped at Exit XXX. Upon re-entering the highway and accelerating to merge into traffic, the vehicle began shifting through gears abnormally. While in approximately 6th gear at around 2,900 RPM, a loud banging noise occurred, followed immediately by a significant loss of engine power. At the same time, the check engine light illuminated. Due to the sudden and unexpected loss of power while actively merging into highway traffic, I was nearly rear-ended by another vehicle. I was forced to take immediate evasive action and pull onto the shoulder to avoid a collision. This incident created a highly dangerous situation not only for myself but for surrounding motorists. This failure occurred without warning and directly impacted my ability to safely operate the vehicle in a high-speed traffic environment. I believe this presents a significant safety concern that warrants investigation. Please let me know if any additional information is required. I appreciate your attention to this matter and request that this incident be formally documented and reviewed.

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.

After putting our Silverado in park it will not turn to the off position or release the key from the ignition immediately. We have to wait 1-3 minutes without attempting to turn it in the off position and then the key will release from ignition. No warning lamps. No error codes on reader. Repeatable by auto technician who suggested a battery change- our current battery was fine and did not fix the issue. If you forget and try to remove the key in under a minute after parking you have to restart the truck, go back to park and then start the 1-3 minute countdown all over before it will release the key. The truck is in park, the parking brake is engaged (although we tried without using the brake and still won’t release key) This means the trucks battery has to run until it will release the key. Or chance leaving the key in the ignition (still draining battery) since it won’t turn to the off position.

Mileage now is 112,000, the truck has burned the right fuel and had proper oil changes. Now the motor is blown as per a certified mechanic northeast auto and truck service in Ocala. First owner called General Motors to see if they could help and was told it should have gone to a Chevy dealer so they won’t or cant help. Motor is blown on a truck with low miles and this is how Chevy appreciate its drivers who purchase their vechiles. Buy American, they say…wow! On [XXX] the same reading came on again. This time it said service emergency brakes, parked it, went in store to purchase food, came out, started truck, drove 4 miles, parked truck went in to work and three hour later came out and white smoke rolled out the back and inside cab. What the heck! Embarrassing … had to leave truck… Chevy replace this engine, please. Was concerned about it INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2021 Silverado LT trailboss. Catastrophic engine failure. Camshaft bearing and lifter failure. First lifter replacement @ 16,000 miles. Second at 104,000 miles. Was told by GM the 6.2L L87 I have is not affected due to a Canadian VIN. The sticker on the truck says Assembled in Kentucky. Gm charged $18,000 for a refurbished motor. The “new” motor had lifter failure at 12,000 miles. Canada is now included in the recall but I was again told by GM that my engine is not affected due to being built in September 2020. I believe this engine bearing failure goes back further than they like to admit.

The engine was burning oil, so did a consumption test. The dealer took apart the engine and found the rings for the pistons were leaking and scaring was resulting. This caused me to buy part of a new engine because it was 6days past warranty with only 44,000mi on it. Also, at 18,000mi, a lifter bent and needed that replaced. There are numerous reports for this engine. It should be recalled! I shouldn't have to pay out of pocket for the defaulted error proned engine.

While driving my 2021 Chevrolet Silverado 1500 Trail Boss, multiple warning lights and messages suddenly appeared related to the ABS and brake system. The brake pedal became extremely difficult to press and the truck became unsafe to drive. The issue happened unexpectedly while the vehicle was in operation, creating a serious safety hazard and risk of accident or injury. After the incident, the truck was inspected by a mechanic who advised that the brake booster had essentially fallen apart and that I effectively had little to no braking capability. I was also informed that the condition and quality of the braking components were not acceptable for a vehicle of this age. This vehicle is only five years old and has been regularly maintained. For approximately the last three years, routine maintenance including oil changes, tire rotations, and inspections were performed at a Chevrolet dealership. At no time was I warned of any brake-related issue or safety concern. A major brake system failure should not occur suddenly on a properly maintained vehicle, especially without warning. This incident was extremely dangerous and could have resulted in a serious crash. I am submitting this complaint because I am concerned there may be a defect involving the brake system, brake booster, ABS system, or related components on this vehicle.

My 2021 Chevrolet Silverado 1500 with the 3.0 diesel is experiencing constant high running engine fan, engine power reduced notification on the dash, fluctuating temperature and is showing a P1098 code indicating the coolant control valve needs replaced. GM has issued a special coverage on this part, which my truck is well withing the parameters for. However, GM tells me the VIN isn't associated with the special coverage. I have spoken with other owners who have the same year / engine vehicle as I do, and GM replaced their part for free under the special coverage. I have not been giving any explanation as to why my vehicle isn't covered even though the bulletin N25250834 clearly states my vehicle and year. I escalated to the GM executive level and have failed to get my coolant control valve replaced. The vehicle reducing engine power is a major safety concern in traffic as well as the obvious over heating issue. GM is blatantly mishandling the situation.
