general problems of the 2020 Chevrolet Silverado 1500 - part 1

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that the infotainment center intermittently went black, and there was water leaking into the vehicle through the top and lower center of the front windshield and the rear windshield. The vehicle was taken to a dealer, where the rear windshield was replaced without a diagnostic being performed; however, the failures persisted. Additionally, the side view mirrors intermittently failed to unfold when starting the vehicle. The contact stated that while driving approximately 40 mph, white smoke emitted from the exhaust, the vehicle hesitated, and it lost power. The check engine warning light illuminated, along with "service electronic stability control", "trailer brake system", "steering assist reduced", "service brake assist", and "brake system failure" messages, and the vehicle failed to exceed 40 mph. The vehicle was towed to a second dealer, arcadia Chevrolet Buick (210 s brevard Ave, arcadia, FL 34266), where it was diagnosed that the lifter and torque converter had failed. The lifter and torque converter were replaced, and the system was flushed. Approximately 800 miles later, the engine failed again. The vehicle was towed to an independent mechanic, who diagnosed that the torque converter and transmission had fractured. The torque converter and transmission were replaced; however, the warning lights and messages illuminated again, and the vehicle continued to hesitate when driven over 42 mph. After being parked for a few days, the warning lights were no longer illuminated and the mirrors opened, but the engine hesitation persisted. The vehicle was not further diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 10,000.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 55 mph, the vehicle suddenly began to shake, vibrate, and lose speed. An abnormal knocking sound was heard coming from the engine, and the check engine warning light illuminated. The vehicle was towed to the contact's residence, where the contact, a master mechanic, examined the vehicle. The contact diagnosed that the fuel management system, lifter springs, camshaft lifters, engine push rods, and rocker arms needed to be replaced. The vehicle was not repaired. The local dealer was notified of the failure and informed the contact that the VIN was not included in NHTSA campaign number: 25v274000 (engine and engine cooling). The contact stated that the vehicle experienced the same failure described in the recall. The manufacturer was not notified of the failure. The failure mileage was 11,450.

My lifter failed in my chevy Silverado 1500 on the highway, causing severe shaking while driving and an array of dash lights. After taking it to a local. Chevy dealer, they confirmed a lifter collapse and possible damage to my cam shaft. I have been up to date on all oil changes with premium synthetic oil, and there were no prior dash lights indicating a problem.

Lifters are failing. Engine is making horrible engine noise. Mechanics said it was lifters.

Dfn failure cylinder 6 140,000 mi oil changes done at 20% using nothing but mobile one full synthetic 0w 20.

Unknown which system failed. While driving on the freeway, truck lost power for a few seconds. Dash lights turned off and back on. Our safety and the safety of others on the freeway were at risk as we had no control of the vehicle. Have not had the truck checked for the problem. Scared to drive it. No warnings appeared.

Vehicle: 2020 Chevrolet Silverado 1500 4x4 lt (5. 3l v8 engine) component: engine (piston rings, lifters, and motor assembly) / powertrain component availability: yes, the failed components/vehicle are available for inspection upon request. What happened and safety risk: while operating the vehicle on prince street in clovis, nm, the engine suddenly began knocking violently without any prior warning or symptoms. Immediately following the mechanical failure, dashboard warning lights illuminated (including the check engine light, abs, and traction control) and the vehicle dropped into "reduced engine power" mode. This caused an immediate and hazardous loss of acceleration on an active roadway, forcing an emergency maneuver to navigate out of traffic and pull over safely. This sudden powertrain failure poses an unreasonable and severe safety risk to the driver and surrounding traffic. Confirmation and inspections: the mechanical failure has been confirmed and diagnosed by hamilton chevy in portales, new mexico, and sanders repair services in portales, new mexico. The vehicle and components have not been inspected by the manufacturer, police, or insurance representatives. There were no warning lamps, messages, or symptoms of any kind prior to the sudden failure.

My 2020 high country with a 6. 2 l is 6 months away from the recall. Driving on the interstate with my family coming out of devil's tower lost all power!!. I just replaced my motor at 60000 miles total engine loss catastrophic bearing failure!! this is the exact sameproblem from the 2021-2024 recall on the GMC 6. 2liter.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at 35 mph, the engine started knocking, and the sound grew louder while making a turn. The electronic stability control and check engine warning lights illuminated. The vehicle was taken to a local dealer, where one diagnostic trouble code was displayed, but the vehicle was not repaired. The vehicle was then taken to a second local dealer, who retrieved a code for fuel injector number eight and diagnosed that the engine needed to be replaced; however, the vehicle was not repaired. The vehicle was taken to a third dealership, knapp Chevrolet, where it was diagnosed that the engine needed to be replaced. The vehicle remained unrepaired. The manufacturer was contacted and opened a case, but no additional assistance was provided. The failure mileage was approximately 94,000.

Engine defect,I was driving down claiborne Ave. ,and my truck just cut off while I was doing 50 mph with my daughter in the truck with me,an 18 wheeler came real close to running in the back of me,also my fuel door popped out,I brought it to west bank GMC lagacy and got it fixed,this will be my 2nd time getting this same part fixed.

The wiring harness failed causing erratic and unpredictable behavior at 65 mph on this 2020 Chevrolet Silverado 1500 with 77,500 miles on the odometer. General motors no longer makes the wiring harness and there are none available in the market. This otherwise flawless truck (for which I paid $40,000 at a reseller in 2024) is essentially now totaled (undrivable) and gm will not take any responsibility or provide any other remedy beside $750 toward the purchase of a brand new truck.

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

Engine failure from bearings and lower rod from lifters. This is the second engine failure in vehicle for the same exact reason per dealership report. Entire engine replacement both times and all lights on dash were on.

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 check engine light indicate p0016 crankshaft camshaft position. It has been diagnosed by a mechanic that the timing belt is stretched. Chevrolet has redesigned these parts due to the premature failure but has not issued a recall to install the redesigned parts.

My 2020 chevy trailboss 6. 2l v8 l87, same engine that has been recalled for 2021-2024 literally went dead in the middle of rush hour traffic. The engine has been deemed dead due to the exact current recall reasons. Seeing that was traffic was flowing at 45mph that was not a good scene as the vehicle " locked" itself into park originally so I was stuck in the middle of traffic. The vehicle has been confirmed seized uo by the portsmouth nh chevy dealer which is the key auto group. Warranty adjusters representatives from a third party, not gm, will be assessing it this week. I purchased an after market warranty not by gm. I had no warning lights leading into the failure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at 25 mph, the vehicle suddenly made knocking sounds. The check engine warning light illuminated. Additionally, the vehicle experienced rough idling and a decrease in motive power. The vehicle was taken to an independent mechanic, who determined the lifters had collapsed and bent the push rod. The push rod was replaced, but the newly installed part instantly bent. The mechanic informed the contact that the cam needed to be replaced. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 107,800.

I am filing this complaint regarding a major engine failure in my 2020 Chevrolet Silverado 1500 equipped with the 5. 3l v8 engine. At approximately 56,000 miles, my vehicle experienced a failed valve lifter, resulting in loud engine ticking, a check engine light, loss of power, and unsafe driving conditions. The vehicle was no longer operating properly and required immediate repair. Although the vehicle had been regularly maintained and had relatively low mileage for such a significant engine issue, I was informed that the failed lifter damaged the camshaft and related engine components, requiring extensive repairs. The total cost of the repair was $6,180, which I paid out of pocket. My silverado was just outside Chevrolet's 5-year/60,000-mile powertrain warranty period by time, despite having only 56,000 miles. A major internal engine failure should not occur on a well-maintained vehicle with such low mileage. After researching this issue, I discovered that lifter failures involving the active fuel management (afm) and dynamic fuel management (dfm) systems in gm's 5. 3l engines have been widely reported by other Chevrolet silverado owners. This indicates a potential design or manufacturing defect rather than normal wear and tear. I am requesting that general motors provide reimbursement or goodwill assistance for all or a substantial portion of the $6,180 repair cost. I believe customers should not be responsible for paying thousands of dollars to repair a known issue on a low-mileage vehicle. I respectfully request that this matter be reviewed and resolved promptly.

I was driving on I-35 in norman, oklahoma, shortly after 7 am, when my 2020 chevy trail boss with the 6. 2 engine stopped running. I was in moderate traffic and shifted the gear shifter to neutral, and the motor would not restart, leaving me in traffic. I was able to slowly get on teh shoulder to avoid a collision, and the engine would not restart. I had teh vehicle towed to ammco in norman, oklahoma, where it was determined that a catastrophic engine failure occurred. This is teh same problems that are associated with recalls on the 2021 and up 6. 2 gm engine. Luckly I was able to get to a safe place and avoid a collision.

The defective manufacturer lifters on my 2020 Chevrolet Silverado 1500 went on my truck damaging the lifters, camshaft, oil pump and I'm sure more than that. I know it's an ongoing investigation/lawsuit with general motors, but they need to held accountable and should fix this issue free of charge. Not everyone has $5k-$10k+ to repair their engine due to their negligence. Thank you.

Chevrolet dealership diagnosed my truck and said the coolant control valve would have to be replaced.

While returning from a camping trip my engine lost power. Luckily I was close to an exit and managed to get it off the expressway and to a parking lot. I was able to leave the camper in the lot and have the truck towed to a dealer 30 miles away. I was informed by the dealer that the engine had sustained major berring failure. I was over 500 miles from home and I had 2 options, wait 2 weeks for a new engine to be installed or trade it in for a new truck. I opted for the trade in because I didn't want to wait 2 weeks. I figure I lost $7000 in trade in value and had to spend $2000 to have my new truck fitted for a 5th wheel hitch.

This was a 6. 2l v8 that is actively under investigation and recall for model years 2021-2024. It is a part of the same gm generation of engines 4th generation, gmt t1xx. I was not told about the active recall for other members of the generation by the dealership in which I purchased it at in August of 2025. I purchased this vehicle less than a year ago and the engine has now suffered a catastrophic failure consistent with known 6. 2l issues.

While driving pulling a trailer with my kid in the car engine began knocking and lost power. Upon investigation it was a failed lifter causing bent pushrod.

* same part gone bad as other recalled vehicles. "coolant control flow valve bad". Engine fan is staying on high blast, message displaying " engine power is reduced" truck will not drive at full power because the truck thinks its overheating because of bad part. If I remember correctly, it is code p1098. Bad part is intermittent. It will happen randomly driving down the road. It comes and goes. I believe this is a safety factor . There is a special warranty or recall regarding this part with my year truck, but not my VIN? why not? same part going bad with same codes and same problem ? please consider looking into this concern and expanding the recall or concern for this reduced engine power safety concern. Thank you for looking into this.

My truck has been in the shop for two weeks. Blown up, oil everywhere. I was told to file a complaint because gm has issues a recall for these engines, but I am not in the years it has been issues for. I was told this case is open and could then cover my engine. Ea25007 is the number I was given.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 35 mph, the vehicle shuddered and lost automotive power. The check engine, abs, and several other unknown warning lights were displayed before an engine misfire. The vehicle regained automotive power before hesitated while depressing the accelerator pedal. Additionally, there was an abnormal humming sound coming from the engine. The vehicle was eventually driven to the dealer where a diagnostic test was performed. The dealer determined there was a lifter failure in cylinder #2, and there was debris in both the engine and transmission, which caused engine and transmission failures. The dealer agreed to a goodwill repair, to cover part of the cost of the repair. The manufacturer was notified of the failure and transferred the contact to the NHTSA to report the failure. The vehicle was not repaired and remained with the dealer. The failure mileage was approximately 70,000.

I am reporting a failure involving a 2020 vehicle equipped with a gm 6. 2l v8 engine that developed a cylinder 8 misfire along with diagnostic trouble codes p0300, p0500, and p0521. Dealer inspection revealed a severely scored camshaft and metal debris present in the engine oil, indicating significant internal engine damage. The failure appears to be related to a lifter or valvetrain malfunction, leading to improper valve operation and engine misfire. This issue occurred unexpectedly and creates a serious safety concern due to the risk of sudden engine failure during operation. This may be associated with known problems affecting this engine type and should be investigated further.

While driving in early morning while still dark outside, loud noise occurred with decreased acceleration on interstate. This placed my life and the lives of others at risk due to not being able to accelerate out of traffic coming behind me. Vehicle taken to chevy dealership who advised lifter had broke and damaged camshaft. This occurred out of nowhere without any warning or lights on dash.

I was driving at approximately 75 to 80mph on the highway when my engine shutoff and the vehicle died while driving it. I was able to coast to the side of the road but had to cross two lanes to the left to do so while weaving in traffic to get to the shoulder of the road. There was no warning of any kind that would have made me aware of an issue prior to this happening. I was unable to get the vehicle started again and had to have it towed to my local dealership hendricks Chevrolet in columbia, SC. That occured on Saturday March 14th 2026, that Monday, I have had all regular and scheduled maintenance done to my vehicle either on time or prior to the recommended time including oil changes and the like. I went to the dealership and they told me that the engine had seized up and that this was a very well documented and common issue with the 6. 2l l87 v8 engine dating back to 2019 but that gm had only issued recalls on the 2021 - 2024 years to correct the issue. I asked the service manager at hendricks Chevrolet to file for a goodwill coverage request on my behalf to cover the repairs of the engine and he refused and stated that I had to do so through gm customer service line. I have done so since and my case number with gm is 92108267. My vehicle is currently at the dealership awaiting the go ahead from gm to replace the engine. I have an extended warranty on my vehicle that goes to 120,000 miles and the issue occured at 114,113 miles. This is a very well documented case where the engine connecting rod bearings fail due to oil starvation that leads to engine seizure.

While driving my 2020 Chevrolet Silverado 1500 equipped with the 5. 3l v8 engine and dynamic fuel management (dfm), the engine developed an internal valvetrain failure resulting in misfires, rough running, and reduced engine performance. The vehicle was diagnosed by a Chevrolet dealership as having failed lifters associated with the dfm system, requiring major engine repairs and replacement of internal engine components. The failure occurred at approximately 81,000 miles and resulted in the vehicle entering a reduced performance condition, creating a potential safety concern when merging, accelerating, or operating in traffic due to the inability to maintain normal vehicle speed and power. The vehicle was inspected and repaired by an authorized Chevrolet dealer. Research shows numerous similar reports from owners of gm 5. 3l and 6. 2l engines equipped with active fuel management (afm) and dynamic fuel management (dfm) systems involving lifter and valvetrain failures.
