2020 CHEVROLET SILVERADO 1500 reports

POWER TRAIN

I have notice that the car jerks hard from time to time and when try to accelerate the car does a quick/short stop then accelerates hards very jerky.

STEERING · ELECTRICAL SYSTEM

While driving I lost the power steering on the vehicle. I took my truck to a chevy dealership and scheduled an appointment for the following day. I research the problem and found that there was a Customer Satisfaction Program bulletin (N252515590) issued covering this specific issue for my trucks model year but it did not cover my specific VIN. I contacted Chevrolet Customer Assistance and they told me to file a complaint with NHTSA.

ELECTRICAL SYSTEM

What component or system failed or malfunctioned, and is it available for inspection upon request? The A/C condenser and the vehicle battery failed. The failed components are available for inspection upon request. How was your safety or the safety of others put at risk? The A/C failure causes the driver's side to blow warm air, creating severe window fogging and reducing visibility in extreme weather, while the electrical/battery failure compromises vehicle operation and safety features. Has the problem been reproduced or confirmed by a dealer or independent service center? The A/C issue matches General Motors Technical Service Bulletin PIT5767A, caused by an internally bypassing condenser due to a mispositioned block-off plate. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has not yet been officially inspected by a manufacturer representative, but the defect aligns with known GM manufacturing specifications under bulletin PIT5767A. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Symptoms appeared suddenly with the air conditioning losing performance (driver's side blowing significantly warmer than the passenger side) alongside concurrent battery and electrical system failures.

The contact owns a 2020 Chevrolet Silverado. The contact stated that while driving between 20 mph and 60 mph, the vehicle shudders a lot while accelerating. The vehicle was taken to an independent mechanic where it was diagnosed with a failure in the transmission. The contact stated he contacted a dealer where they confirmed the failure but stated there are no recalls nor TSBs related to the failure, although there are recalls for different model vehicles that have the exact same transmission as the contact's vehicle. The contact referenced TSB 19-NA-121 (powertrain); however, the VIN was not included in the repair. The contact stated he could feel the shaking shuddering. The manufacturer was notified of the failure. The vehicle was not repaired.

SERVICE BRAKES

While driving my 2020 Chevrolet Silverado 1500, the braking system suddenly malfunctioned without any prior warning. When I released the accelerator, the vehicle began slowing as though the brakes were being applied even though I was not pressing the brake pedal. When I attempted to brake normally, the vehicle did not stop as expected and braking ability was significantly reduced. The red BRAKE warning, ABS warning, traction/ESC warnings, and check engine light illuminated. The dashboard displayed “Brake System Failure – 43 MPH Top Speed,” “Service ESC,” and “Service Trailer Brake System.” Because of the reduced braking ability, I stopped the vehicle and had it transported by flatbed tow to a Chevrolet dealership rather than continue driving it. The Chevrolet dealer inspected the vehicle and documented diagnostic trouble codes P25A2 and C053D. The dealer stated that the Brake System Control Module requested the warning light and that updated software was available to address these codes. The dealer reprogrammed the Brake System Control Module according to a GM technical service bulletin. No mechanical brake components were replaced. I was charged $362.95 for the diagnosis/reprogramming. I am reporting this because the failure occurred suddenly while the vehicle was being driven and resulted in significantly reduced braking ability, creating a serious risk of a crash. The vehicle had approximately 74,221 miles at the time of the incident. The dealer repair invoice documenting the codes and repair is available upon request.

STEERING · ELECTRICAL SYSTEM · EXTERIOR LIGHTING

Body to frame ground cables corroded in half two different times within about 6 months. First time engine wouldn’t start had to have it towed to dealer for repair, over 30 codes were shown when this happened. Next incident some of my lights were working intermittently and my steering was rendered inoperable for 20 to 30 seconds at a time making it impossible to steer the vehicle, several codes were found when this happened, I drove the truck to a Chevrolet dealer for repair. Both repairs were deemed to be corroded ground cables. Chevrolet has a “customer appreciation program” covering 2019-2024 Silverado trucks but for some reason my VIN number doesn’t land in the program even though it has the same issues that are covered for the other silverados.

SERVICE BRAKES

Complete brake system, master cylinder, pads, rotors. Only 75000- miles. Morning start and the brakes are locked up. Had to get towed and the entire system needed to be replaced. So after several days and almost 5,000 I started driving home. After about 5 miles something fell off the front brakes and bounced along underneath but I was close to home so I continued and didn't need to apply the brakes until my driveway and then a terrible grinding sound. Called the dealer (Modern Chevrolet) Winston-Salem NC. Turns out the Einsteins who did the work forgot to tighten the bolts holding the rotor and one fell out and the other one was grinding against the wheel. So another extended stay at the dealership to correct this, a new wheel and correction to the brake components.

FORWARD COLLISION AVOIDANCE

Vehicle came to abrupt stop with no warning and no reason. There was not a vehicle in front of me, nor behind me when this occurred. If there had been a vehicle coming behind me there would have been a collision.

ELECTRICAL SYSTEM · SERVICE BRAKES

While stopped at a highway red light, the vehicle jolted forward and numerous dash lights came on, including messages saying “Brake System Failure, Service ESC, Service Trailer Brake, Service Parking Brake, Engine Power Reduced, Power Steering Reduced.” This is the first time any of these messages have ever appeared. This made the vehicle incredibly difficult to steer and the braking ability was almost non-existent. Had this happened one minute earlier or later, a multi-vehicle and potentially fatal accident would likely have occurred. Vehicle was towed to a dealer who confirmed the error messages and severely reduced performance. To me, this seems consistent with GM service bulletins PIT5730 and 20-NA-073. The dealer, however, is quoting me $3,700 to repair the master cylinder and electronic control braking module. Whatever the case, this absolutely needs to be upgraded to a recall before this happens to somebody at the wrong time.

On July 22, 2026 took truck to dealership for oil change and reported getting random (trailer brake, power steering) service alarms. Was told it might be a ground strap issue and was sent on my way. After investigating, there is a GM service bulletin (#23-NA-201) on the issue but does not cover my truck. After a week of vacation, began driving truck again and alarms became more frequent, including loss of power steering and jerking of steering wheel while driving. Arranged with dealership to replace the ground strap (at my expense). By the time they could schedule, the alarms were constant and the truck had completely lost power steering. One of the power steering failures nearly resulted in an accident while turning.

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.

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.

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.

ELECTRICAL SYSTEM · SERVICE BRAKES

I went to the store and my brakes were working as normal. When I started my truck to leave I had a hard pedal and there we several warnings on the dash. One said to get service and the other said to limit speed to 43 MPH. I had almost no braking power. Fortunately, I was close to home and the speed limit was 30 MPH all the way home. Once I arrived home I cleared the code with my ODBII scanner and the brakes worked as expected. If I was towing my boat this could have been a bad situation resulting in an accident. I haven't had the same issue in several days however this has to be a huge liability for GM. I'm sure that this is a known failure mode for GM.

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.

POWER TRAIN · WHEELS · FUEL/PROPULSION SYSTEM

While driving at highway speed, my vehicle developed a serious transmission problem. At approximately 75 mph, it suddenly lost the ability to maintain speed and dropped to about 55 mph despite throttle input. Engine RPM increased significantly and the vehicle had greatly reduced propulsion. Normal operation temporarily returned after the vehicle was shut off and restarted. The vehicle has also experienced harsh shifting, vibration, limp-mode behavior, a check-engine light, and I reported a momentary wheel-lock event. These symptoms create a safety concern because an unexpected loss of propulsion or abnormal transmission behavior at freeway speeds can increase the risk of a collision. The vehicle was inspected by an authorized Chevrolet dealer. The dealer documented transmission-related diagnostic codes including P0700, P0970, P0968, and P0711. The dealer's repair order specifically referenced GM program N242454441-03, described transmission control-valve wear and pressure loss, and recommended replacement of the valve body. A separate repair estimate included the valve-body assembly and related transmission service parts. Despite the dealer recommending valve-body replacement, GM/dealer coverage was denied primarily because P0747 was not present at the time of diagnosis. I am reporting this because I am concerned that transmission control-valve/valve-body deterioration may cause harsh shifting, reduced propulsion, limp mode, or other safety-related symptoms before or without P0747 being stored. I am asking NHTSA to review whether vehicles with the same underlying valve-body failure may remain on the road because the specific qualifying diagnostic code is not present during a dealer scan. The vehicle and transmission are available for further inspection if requested.

ENGINE · FUEL/PROPULSION SYSTEM

Description of Problem: While driving, the engine intermittently revs on its own without any input from the accelerator pedal. During these episodes, the vehicle also shakes/vibrates noticeably. This has occurred [once / multiple times — specify frequency, e.g., “several times over the past X weeks”]. The engine revving is not consistent with normal acceleration and appears unrelated to throttle position. The shaking is felt throughout the cabin and is most noticeable [at idle / at speed / when the revving occurs — specify if known]. Safety Concern: This creates a risk of sudden, unintended changes in vehicle speed or loss of control, particularly if it occurs in traffic, while merging, or at highway speed.

ELECTRICAL SYSTEM · SERVICE BRAKES

The Electronic Parking Brake System on my 2020 Chevy Silverado 1500 continuously malfunctions. Chevy/ GM Customer Support has been made aware of this issue and continues to disregard it entirely. The Electronic Parking Brake, which is an automatic function that cannot be turned off or bypassed, fails to fully disengage when the vehicle is taken out of Park. The Electronic Parking Brake remains very slightly engaged, producing a slight noise while driving and causing excessively premature wear on the vehicles pads and rotors. My vehicle has about 64,000 miles on it, and I have had to replace my rear brakes twice now already, due to this issue. The majority of those 64,000 miles are from uninterrupted highway driving. Each time the rear brakes were replaced, I had the dealership inspect the braking system. The dealership was not able to definitively confirm for some reason but was able to speculate that the aforementioned is likely what is going on. I find that any malfunction of such a critical part of the vehicle and the safety of it's operators and passengers poses a major safety risk.

Dear Sir or Madam, I am submitting this complaint to request that the Federal Trade Commission investigate General Motors (Chevrolet) regarding what appears to be a known engine defect affecting the 2020 Chevrolet Silverado and the company's handling of this issue. I own a 2020 Chevrolet Silverado. In September 2025, when my truck had only 45,494 miles, I experienced an engine misfire consistent with a defect that has been widely reported by other owners. Through my research, I discovered that General Motors was aware of this issue and, rather than correcting the underlying mechanical defect, reportedly issued a Technical Service Bulletin (TSB) instructing dealerships to reprogram the Engine Control Module (ECM) to reduce or mask the symptoms instead of permanently repairing the root cause. Now, less than one year later, my truck is experiencing the same engine problems again. Although my vehicle has relatively low mileage, it is no longer covered under the factory warranty because of its age rather than its mileage. When I contacted Chevrolet Customer Assistance, I was advised to work with my local dealership to determine whether I might qualify for a "goodwill" repair. I do not believe it is fair for consumers to rely on discretionary goodwill assistance when the manufacturer was allegedly aware of a design defect before or during the time these vehicles were sold. Based on my research, properly repairing the underlying cause of this engine failure can cost as much as $15,000. Consumers should not be expected to bear the financial burden of repairing a defect that the manufacturer allegedly knew existed but failed to adequately correct. I respectfully request that the FTC investigate whether General Motors engaged in unfair or deceptive business practices by: Continuing to market and sell vehicles with a known engine defect. Addressing customer complaints with software reprogramming rather than permanently correcting the underlying mechanical issue. Failing

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.

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'm experiencing all the documented issues with the 10L80 10 speed transmission. Identical to all the recalls. It's shifting poorly, torque converter shudder, lose of power, unreliability, and serious safety concerns. I've tried to communicate and find a resolution to these issues through the dealership and GM. Of course getting nowhere. I don't feel a 60k dollar truck should be in this kind of condition. Recently the ac compressor went out. Conveniently after the 6.2 was considered faulty and was replaced but transmission denied. Which the dealership GM expressed in no way was any factors the warranty companies claims of a taller tire being on the truck. Being the issue at all for the transmission failure. Also the dealership didn't check a box. One that I can not physically check. Which they put on me. They swapped the stock tires to the taller brand new set I'd just bought for my trade in. Never stating anything about the tires being taller voiding the warranty I just paid for. Why would I deny the part of the extended warranty that I wanted. Cause of the suspension and drivetrain. Either way this truck is not safe to be on the road. It struggles to maintain speed on the highway. Eventually leading to the torque converter free spinning and making all kinds of noises and vibration. Of course once I've assisted it to violently shift through the gears and hopefully into 10th. On occasions it never makes it that far. Either way I feel this falls directly into the recalls with the same model and year. They replaced the 6.2 cause of cylinder failure and oil consumption. Well the next in line for the drive train is the junk 10 speed. Not sure how it can't be related. The long and stressful time. I've put into finding a solution with the dealer or manufacturer. They blow me off or just don't give me any info. I feel that's their way of dismissing not only the failure of the salesman not properly doing his job. Which the GManager also stated mistakes happen. Not OK
