2021 Chevrolet Silverado Complaint Log

As of august 19, 2026 my engine suffered a catastrophic failure with code P0016 which is cranckshaft camshaft lifter failure. Engine will be replaced. Currently at the dealership for replacement. Had the truck for 2 months and I’m requesting that GM fully replace my truck with a different one because I’m sick of hearing all the failures going on with the 6.2 engines. Such as my truck.

Shuddering at 25 to 50 mph, harsh shifts, hesitation.

My husband was driving his 2021 Chevy Trailboss when it went into limp mode. It had to be towed to the dealership and it was uncovered that his truck was throwing out codes P0700 P2732 which is a known issue with this truck, resulting in internal valve body hydraulic failure. Since his vehicle is at 70k miles, and over the 60k, the dealer is pushing back and trying to say they don’t have to cover it. GM states that we should pay and then submit a reimbursement form. This is a $3800 fix. This is not our responsibility and this is unsafe. This should be a safety recall for all vehicles of this make, model, and with this transmission. Additionally, he had to have his engine replaced on this truck (we bought it brand new in 2021) with only 10k miles on it. This truck should not be built anymore and anybody facing these issues should not be held liable for them. This is a manufacturing issue and it is only one company’s fault, General Motors!

Currently had my engine go into "limp mode" after checked engine light came on with code p1010. The coolant control valve is what is the problem, and GM/Chevy has issued a special coverage on this known part for my year make and model (Bulletin N252508341). However, according to the dealership, my VIN does not qualify for this known issue, regardless of my faulty part matching the special coverage for the year make and model of my vehicle. Now I'm stuck paying for the empty promise from Chevy.

Vehicle bucks upon acceleration in the rear end. Dealer recommends replacing the transmission.

Check engine for cam shaft sensor wiring harness burnt up and damaged in numerous places shows bulletin board for this issue online but no recall has been made for this safety issue

The key will not release from the ignition when in park. This is all over the internet as a very big problem. People are bypassing the ignition interlock so they don’t have to leave the vehicle unattended with the key in the ignition inviting theft. Therefore while driving the ignition could be cut off and the key can come out. This is a huge safety issue. This will kill people.

While driving at ~50mph, the truck immediately went into reduced power mode, temperatures spiked to 260 from 210. Engine code P1006 showed indicating coolant control valve failure. After experiencing, I discovered that GM issued Special Coverage for Coolant Control Valve (N252508341). However, the local Chevy dealership indicated my truck would not be covered even though it is within the timeframe/mileage, and falls in the year/make/model categories. According to them, the coverage is VIN specific and my VIN is not listed. They directed me to Chevrolet Customer Care. Customer Care did not acknowledge the Special Coverage until I directed them to the correct bulletin. They further indicated because my VIN was not covered, they would not be able to do anything. This issue is HIGHLY known by GM, but they have failed to remedy appropriately. It is also a safety hazard, especially in my case, where the failure occurred on the highway, at speed with cars behind me, and resulted in the truck immediately ceasing normal operation causing the potential for property damage and/or injury.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving approximately 30 - 60 MPH, the transmission failed to shift properly, and the vehicle hesitated while depressing the accelerator pedal. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed, and the contact was informed that the valve body needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The approximate failure mileage was 105,000.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle came to a complete stop without warning. The contact stated that the failure had occurred twice. During the first failure, the vehicle was towed to the dealer and a lifter inside the engine was replaced. The contact stated that after the second failure, the contact allowed the vehicle to sit for a while before restarting the vehicle and continued driving. The vehicle was driven to the dealer, where it was diagnosed and determined that a lifter and the camshaft needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 73,000.

2021 Chevy Silverado 5.3 trail boss lifters has failed on this driver two times while driving on highway engine lost power with my family in the vehicle. Dealer warranty fixed lifter the first time lifter went out at 1100 miles. The vehicle has failed again with multiple lifters going out and camshaft needing being replaced also on my extended warranty at 73000 miles. I do not want to take this vehicle back in my possession as it has put me and my family at risk twice being stuck on highway with no power.

Transmission needs to be replaced at 77000 miles!! A KNOWN problem with this make/model/year and NOTHING is being done!!!!!!!!!!!!!!!!

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while his wife was driving approximately 65 MPH, the vehicle lost power and stalled. The vehicle failed to restart. The vehicle was towed to a dealer where it was diagnosed with an internal engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 120,000.

I have a 2021 Silverado with the 6.2L engine. I had received the recall notice, but it took several months before I could get the truck checked. By the time I was able to get it inspected, the truck had over 100,00 miles, with the symptoms associated with the 6.2L engine failure. It was said to have passed inspection, but I had my doubts. Low and behold, my engine failed not once but twice. The first time I was told it was not due to the recall and paid out of pocket. The most recent failure, (same exact failure as before, and nearly caused an accident) happened last week. I towed it to a different dealership than where it was inspected and where the last repair occurred, and was told it needed a new engine. I called and was told by the dealership that a new engine was ordered, and they were waiting to hear back from GM on if they would cover it or not. I was also told they were very confident GM would cover it, and that is why they ordered a new engine. A few days later, I get a call and find out GM is in fact not covering it and the repair is around $12,000. I am beyond frustrated at GM for not taking accountability, and the dealership for giving me false hope that this would be covered.

The Coolant Control Valve (DTC Code P1098) is failing and only certain trucks are covered under GMs special coverage, being as this is a common issues why aren't all the trucks covered

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).

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that the engine occasionally overheated. The check engine warning light was illuminated for a day, and there were six diagnostic trouble codes displayed. The vehicle was taken to the dealer to be diagnosed, and it was determined that the coolant flow control valve was inoperable and needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and confirmed that the repair was not covered under warranty or recall. The contact became aware of GMC Special Programs: N252508340 and N25250834, which were associated with the failure; however, the VIN was not included. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 105,000.

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.

I just got this car from a used car dealership, it has 170K miles and the engine just stopped on me today. It’s very disappointing for the car to just stop like this. While I had my family in the car with a new born. Very disappointing

I was on the highway doing 70 MPH with my family driving down I-40 through western NC (mountainous terrain) when my brakes went out and the vehicle went into limp mode. I was able to safely pull over thank God and then had my vehicle towed to the dealer. The dealer just informed me that a software update is needed, and not covered under warranty. There are multiple safety bulletins coming out for related years and issues related to the braking system of this make/model and I would like this documented as well as Chevy to cover the cost of repairing this defect.

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.

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

Truck blew up driving down the road and the the Chevy app gave me a code and it was the same code it is recalled for but I was told it wasn’t under recall

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.

Catastrophic engine failure. Confirmed by GM dealer. No symptoms prior.

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.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while attempting to start the vehicle, the engine failed to crank. The contact originally suspected a battery failure, as the vehicle had recently been involved in an accident that left the passenger-side mirror damaged with exposed wires. While driving at 70 MPH, a semi-truck sideswiped the passenger-side of the vehicle, causing a dent on the front door and a fractured side-view mirror. The semi-truck driver did not stop, and the contact's son drove the vehicle to the nearest exit. No air bags deployed, no warning lights illuminated, and no injuries were reported. A police report was filed. The vehicle was initially towed to a collision center, where it was determined that the battery was not the cause of the starting failure. The vehicle was then towed to a dealer, where it was diagnosed with camshaft, timing belt, and actuator failures. Upon removing the camshaft, metal shavings were found inside the engine, and the dealer determined that the engine needed to be replaced. The contact associated the failure with NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 91,733.

On or around XXX a my 2021 Silverado started making a rattling sound from the engine. The truck began to stall and the engine shut off three times while driving. I attached scanner the next day and the track showed P00011 and P00016 codes. Those codes are for the Camshaft Sensor and the Crankshaft Sensor. I went online and did research about the two codes and discovered there had been a couple recalls for these codes concerning my year model truck: (Recall Number 25V-274; GM: Campain N252494000). NHTSA Engineering Analysis EA25007 or RQ26001 I spoke with the Dealer I purchased vehicle from (Lynn Layton Chevrolet - Decatur, Al)and they said they will not begin repairs until they receive payment from GM or myself. I then spoke with Tyler at GM Corporate Customer Service. He said my VIN was not included in the GM Campaign|Recall. I asked why not because it is a 2021 Silverado and I’m having the exact same problems as vehicles included in the recall. He said because they checked their system and the parts used on my truck were from a different manufacturer than those included on the recall. I said that shouldn’t matter because my truck is having the same exact problems. I asked him to check and see if GM would be able to provide financial assistance to have motor repaired or replaced. Tyler told me that GM will not do repairs - they will only replace the engine. He said GM would not provide any financial assistance because my truck has 170k plus miles on it. I informed Him that I had previously taken my truck to Lynn Layton Chevrolet about these symptoms and it was diagnosed as transmission/torque converter problem. They changed transmission fluid and charged me ~$700. I then asked if GM would authorize a “Goodwill Replacement”. He said they would not. I called Lynn Layton Decatur back and asked how much would engine and reps if I have to pay for it. They said 10k -12k A local mechanic said he will fix for $6,000. Please help me get this resolved.

10 speed transmission failed at 70K miles. Metal found in the torque converter. Manufacturer recommended routine maintenance was performed on transmission. There needs to be a recall on 2020 to 2021 vehicles with the 10 speed transmission due to the reporting of safety issues of the vehicles locking up while driving. I was lucky to feel the issue happening and getting off the road before it was able to lock up on me causing serious injuries. This needs to be addressed and taken seriously before someone loses their life. Best regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

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.

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.

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.

Lights on the panel reads service parking break, engine, transmission, abs, traffic control and esc service. All these lights are on. Idling rough, white smoke with rich smell. Had a diagnostic read cam/crank and lifters bad… estimated cost 15,000. Total new engine install.

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.

Transmission shutter at low speed acceleration

1. An electrical failure from a component of the main wiring harness causes the ECM to respond with Service ESC, Reduced Engine Power, Service parking brake, service traction control. 2. Interstate driving requires maintaining rate of speed to avoid collision. The vehicle is much more difficult to drive as acceleration is very poor and also main safety functions like traction control are disabled. 3. Check engine light stays on until codes have been read. After codes have been cleared, normal driving and usually turning or bumps in the road tend to trigger the recurrence. 4. The vehicle has only been reviewed by the dealership for this issue. 5. No warnings before the failure occurs.

Air bag light was on , took to dealership because this was absolutely a safety hazard! The left front crash sensor is defective.

I have 112,000 miles on my truck and my 6.2l motor is going out or knocking. I am very unhappy that my truck is not covered under the recall and I would like to understand why it is not since this is the issue of the recall. I would like to clarification on this and what options I have since it is going to cost me 14k to replace the motor. Case #101943027

It started backfiring and knocking

May 28 ,2026 I left work to get some lunch And when I went back inside my vehicle I turned it on and the check engine light came On and on the dash it was telling me to park the truck and it wasn’t going more then 45mph so I called my dealer ship simspson Chevrolet in garden grove and they told me they couldn’t do anything because it wasn’t under warranty so I had to take my truck to a near by auto shop because my truck is my daily and I use to get to work so the. The body shop found out the problem it was the wiring harness it was the way they installed the wiring harness it’s manufacturing I called my insurance company and I called GMC directly and they don’t want to help me

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.

The contact owns a 2021 Chevrolet Silverado LD Crew. The contact stated that while reversing the vehicle, the rear end locked up. Also, when accelerated, the vehicle jerked forward and stalled. When the vehicle is shutdown and restarted the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage. 64,900.

Sudden loss of power steering, usually upon initial start. May return, may not return during drive. Began around 1 week ago. Sudden loss of power steering when turning either right or left has occurred causing a dangerous situation. Upon loss of power steering, 2 warnings appear. One for loss of power steering and the other for the trailer brake. Have never trailered anything with truck. Check engine light has come on at times, others it has not. Steering failure has occurred approximately 6 times. An internet search found some reference to my vehicle being informally added to the recall affecting other GM Vehicles. Vehicle has not been inspected yet.

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.

Truck started ticking/clicking a few months back and the ESC or ECS light came on took it to the dealer Carl Black Chevrolet in Orlando, where the was supposed to to fix the problem under the previous owner, my boss who gave me the truck and 30 days after receiving the title the motor is bad. 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)

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that the vehicle made an abnormal sound while driving. Upon taking the vehicle to an independent mechanic for an oil change, it was discovered that there were metal shavings inside the engine oil. The vehicle was taken to the dealer, where it was diagnosed and determined that the engine needed to be replaced, and the contact was provided an estimate for the repair. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the VIN was not included. The manufacturer was contacted and referred the contact to the dealer for diagnosis, and to the NHTSA Hotline for assistance in adding the VIN to the recall. The failure mileage was approximately 104,000.
