2020 CHEVROLET SILVERADO 2500 Recalls, Complaints & Safety

My dash has been displaying intermittently “Service electric trailer brakes”. I have recently purchased a 30’ travel trailer. After driving a couple hundred miles with trailer in tow. The code started appearing even with the trailer not connected. I have contacted GM and they have indicated no recall on electric brake controller.

This vehicle does not recognize that the gear is on park. Due to the issue, it has left me stranded twice. The first time it was at a very remote area up in the mountains. I was stuck for hours due to battery dying. The second time being a very dangerous situation Because it was a very dangerous area late at night.

THREE WEEKS I NOTICED THE HEADLINER ABOVE THE REAR WINDOW WAS WET. THE REAR WINDOW HAS SOME CRACKS ON THE TOP PLASTIC MOLDING THAT HOLDS THE WINDOW TO THE CAB OF THE TRUCK. THIS MOLDING IS IN BETWEEN THE HEADLINER AND THE REAR GLASS.

Pulling out onto road, heard a bang, no forward or backward, unable to move vehicle, brought to repair shop, says output shaft is sheared off, 68000 miles on it, looked on line, apparently common defect, my son in laws friend just had his happen getting off ramp exit, 80000 miles, I’ve read where low as 20000 miles, as well as 59000, 33000 ridiculous crap made in USA…. Please help! No repair as of yet.

The contact owns a 2020 Chevrolet Silverado 2500. The contact stated that while driving at 50 MPH, the vehicle went into LIMP Mode. The check engine warning light illuminated, and the messages "Service Emission System”, “See Owner's Manual", and "65 MPH Max Speed" were displayed on the instrument panel. The vehicle was taken to the dealer, where it was diagnosed, and determined that the diesel exhaust fluid gas tank connector terminal had overheated, and the gas tank and the wiring harness needed to be replaced. The vehicle was not repaired due to the cost. The vehicle remained at the dealer. The contact associated the failure to the Global Warranty Management: N212342980. The manufacturer was not notified of the failure. The failure mileage was 173,794.

On approximately January 24, 2026 my 2020 Chevrolet Silverado 2500HD equipped with the 6.6 Duramax Diesel displayed an error code (P20B9). This error code was found to be related to the diesel exhaust fluid system specifically relating to "Reductant Heater A Control Circuit/Open." On January 27, 2026, the vehicle was diagnosed at Chevrolet dealership and the following was reported "Diesel Emissions Fluid Tank Remove and Replace - P20B9 SET FOR REDUCTANT HEATER CIRCUIT...COMMANDED ON AND ZERO AMPS..CIRCUITFAILURE... DISCONNECT PUMP MODULE AND BURNED/OVERHEATED TERMINALS..PUMP MODULE AND HARNESS PART OF TANK ASSEMBLY... LABOR TIME ADDED TO PERFORM MALFUNCTION/TAMPER TEST TO CLEAR EMISSIONS MESSAGE...." I found the "burned/overheated terminals" comment to be alarming. I looked into this matter further and found a GM Service Bulletin (21-NA-006) from October 2022. This bulletin identified this issue which contained an image showing burned/overheated terminals. The identified cause within the bulletin states "This condition may be caused by a poor connection at the Emission Reduction Fluid Tank electrical connector." I believe this should upgraded to a safety recall due the the potential of this terminal connection catching fire which could be detrimental for the operator, passengers, property, and the public.

10L1000 transmission, began having problems with delays and harsh gear engagement. Flare shifting and shuddering. Finally starting having transmission overheating issues while towing. I had to make several unsafe stops with a trailer to wait for the transmission to cool down again before continuing to get it home. Saw trans temps up to 240°F on flat land with 40° outside temps. I could smell the hot transmission fluid inside the truck. When I went to check the fluid level of the transmission, the fluid was full but had a large amount of glitter like metallic flakes. The fluid was very dark brown in color and smelled terribly burnt. The last recall I took in to the dealer for was about the transmissions possibility of failing, locking up, along with the rear wheels at any speed. I have young children that ride in this truck, that in it self was unsettling and unsafe. But then to have issues with absolutely no warning light was concerning. Ive since ordered an aftermarket built transmission to avoid repeating the same issues with a factory GM replacement. My factory warranty had also ended a few months prior to having these problems with it. Leaving me to completely foot the bill for it to be replaced. I had to pull money from my retirement early to cover costs, in fact costing me much more than just the sticker price.

The engine block heater in my truck keeps tripping the circuit breaker. Dealership says it that 'it appears that the block heater cord is shorted recommend replacing cord' estimate $500. I understand that Chevy has recalled some trucks from this year for this very problem however it and they don't include my truck. This is a fire safety hazard!!! The company admits it is a safety issue. Why isn't my truck on the list? Here is the article I found on it. 2020 silverado engine block heater cord recall +5 General Motors has issued recalls affecting 2019–2020 Chevrolet Silverado 1500 and various heavy-duty models (4500HD-6500HD) due to a fire risk from the engine block heater cord .

I am filing a safety and health complaint regarding a known rear window water intrusion defect on my 2020 Chevrolet Silverado 2500 with approximately 56,000 miles. Despite the severity of the issue, the dealership has refused to provide a permanent repair. This defect is widely documented and has resulted in a recall in Canada, yet no recall exists in the United States—despite significantly more of these vehicles being sold here. The inconsistency in recall coverage is deeply concerning. My vehicle experiences substantial water intrusion that has saturated the rear headliner, rear seat area, and carpeting. This creates a serious health concern, particularly for rear-seat passengers, including children. Prolonged moisture intrusion creates a high likelihood of mold growth beneath interior components, which General Motors has failed to address. There is also a serious safety risk. The rear sliding window heater module is mounted directly to the rear window. It is well known that when this module is exposed to moisture from the leak, it can cause the rear window to shatter or explode. The dealership has acknowledged this risk. A rear window shattering while occupants are in the vehicle could result in serious injury. When covered under bumper-to-bumper warranty, the dealership’s only solution is a “reseal” of the rear window. This is not a permanent repair, and many owners report repeated failures after resealing. This issue is easily verified through widespread consumer complaints. These trucks are expensive vehicles, and owners should not be forced to accept temporary fixes for a defect that presents clear health and safety risks. I respectfully request that NHTSA investigate this issue and take appropriate action.

The contact owns a 2020 Chevrolet Silverado 2500. The contact stated that while driving at an undisclosed speed, the rear wheels locked up momentarily. The check engine warning light was illuminated. The vehicle was previously taken to the local dealer to be repaired under NHTSA Campaign Number: 24V797000 (Power Train). The vehicle was repaired, but the failure recurred. The manufacturer was contacted, who confirmed that the recall repair was a one-time free repair, and no further assistance was provided. The failure mileage was approximately 188,000.

Intermittent steering catches

I just financing this car and dealer write on dmv price of $57,057 with 63,631 miles that the tell me that was a pre contract on 9/13/24 then they then the bring the truck on 9/15/2025 with 64156 miles at the price of 61,777 on the contract i dont know what to do

While driving home I noticed a vibration in the steering wheel. Once I got home I looked over the tires because I had one start to come apart a month ago so I was worried another one was doing the same thing, and I was correct. The tire has roughly 12k miles on it

As I was driving I got a really bad vibration once I pulled over to check it out I discovered the tire was separating . The tires had about 10,000 miles on them. I have another tire that just recently did the same thing I will also be reporting

The rear camera goes out when backing up. This causes a safety hazard due to not being able to see.

Transmission valve body issue

I am writing to express my serious concern and frustration regarding the unresolved recall on my 2020 Chevrolet Silverado 2500 (VIN: [XXX] ). Despite multiple visits to multiple dealerships, I was repeatedly told that the necessary parts to complete the recall repair were on back order and instructed to “wait for parts.” No interim solution or assistance was ever offered. As a result of this delay, my vehicle broke down without warning, leaving me stranded on the side of the road. This created a hazardous situation and significant disruption to my day. To make matters worse, I had to pay out of pocket to have the truck towed to a repair shop in an effort to get it operational—an expense I should never have incurred given the known recall and repeated attempts to have the issue corrected by Chevrolet. I have been a loyal Chevrolet owner and have always trusted the brand for its quality and dependability. However, this delay and lack of proactive support is causing significant inconvenience and eroding that trust. This situation is unacceptable for several reasons: 1.Safety Risk and Recall Obligation: Chevrolet acknowledged the defect by issuing a recall, yet I have been forced to operate a vehicle that does not meet your own safety standards for months. 2.Repeated Service Attempts with No Resolution: I followed the proper process and visited an authorized dealer multiple times, only to be turned away each time with no solution beyond “wait for parts.” 3.Breakdown and Financial Loss: The vehicle failure and subsequent towing expense are a direct consequence of Chevrolet’s inability to provide timely parts or alternative accommodations.

Power tailgate opening unexpectedly. Tailgate opens and closes without warning. The same issue that Safety Recall N232426400 describes.

We received a recall on this truck 2/2025 showing that there was a transmission control valve defect that was causing excessive wear on the gears. We took it into Sands Chevrolet and they did a repair under warranty. Within a few weeks, the truck again lost power, would not go over 30 MPH and caused a safety issue as it happened while on the highway. We immediately took the truck back to Sands who informed us of the recall and that the transmission needed to be repaired because of the excessive wear under the recall. Sands Chevrolet told us it would be 2 months before they could repair it. However, there was another local shop that could so we took it there and had it repaired within days. The dealership told us to submit our invoice and credit card statement showing that we paid the $5575 out of pocket that we were told we would be reimbursed for. Now, Chevy is denying that there was even a recall on the vehicle.... but I have the letter from GM showing the recall and the local Sands dealership is the one that told us to go get it fixed. I have the scan of the safety recall, but it is not letting me upload it here. It is GM Recall # N242454440

The tailgate would open and close on its own. I was about ready to connect my fifth wheel RV for a trip when suddenly as I closed the truck door to back up I saw that the tailgate had opened. I proceeded to put it in park and the tailgate closed on its own. Got out as leaving the door to the pickup I walked to the rear of the truck to notice the tailgate open and close on its own. I am expecting this issue to be recalled for a repair as I have read that 2024 has this same issue and that they will be recalling trucks from 2020-2024.The issue is due to a faulty relay when wet. This vehicle is equipped with power-unlatching tailgate. I believe if this issue would have went unnoticed and continued to hook up my fifth wheel the damage would have been horrific. Thanking you in advance, Sincerely, [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving on Interstate 75 in Ohio when the engine suddenly overheated and completely locked up we were pulling my travel trailer camper at the time which we ended up getting off of an overpass and blocking traffic for several hours until we got the vehicles moved Chevrolet did eventually replace the motor and the entire cooling system with what they claim is a new motor in October of 2024, and within the last couple of days I have noticed a smell coming from the engine compartment that was reminiscent about the smell when it locked up I'm afraid they stuck another motor in my truck that has the same exact issues and once it goes out of warranty I'm going to be stuck with another broke down truck

Rear spoiler is leaking water into the cab causing the headliner and rear seat to get wet when raining outside

While driving the truck it will have a hash upshift which has happened on five different occasions plus on two other occasions after first startup and drive the transmission will not shift out of third gear it will just wind up the RPM's as if transmission is stuck in third gear. I have to let off throttle then accelerate and back-off a couple of times to get transmission to shift out of third gear. The software upgrade is not a fix for this recall as it does not address the problem. The valve body installed in these ten speed transmission is a manufactures design flaw along with using inferior parts required for the safe operation of this vehicle. There are documented claims of the valve body failing causing catastrophic failure of the entire transmission and GM Corporation will only cover the valve body. GM has told it's customers that they will warranty the VB only that the other damages are not covered. The recall letter I receiver indicates that only the VB is covered. This is unacceptable. It is because of the VB failure that the transmission will suffered catastrophic failure, Without a properly functioning VB the transmission cannot receive the lubrication it needs to function properly. I have not had the software update as their are reports of customers trucks going into limp mode shortly afterwards. Their trucks are then parked on dealer lots as parts are currently unavailable for weeks at a time in some cases months. These customers use these truck for their livelihood and they invested a large amount of money purchasing these trucks only to be told So sorry GM will not cover your claim even through it was our defective VB that destroyed your transmission. These trucks are not cheap to purchase nor to properly maintain.

Def tank heater. I had one replaced @ 24K and another replaced 47K

The contact owns a 2020 Chevrolet Silverado. The contact stated that while attempting to remote start the vehicle, the vehicle failed to start. The contact was able to manually start the vehicle however, the message "Service Emissions System - Speed Limited to 65 MPH" was displayed. The contact stated while driving approximately 25 MPH, the "Check Engine” and “Speed Limit 65 MPH" messages were displayed.

We received a recall notice 4 weeks ago on our Chevrolet Silverado diesel truck. VIN:1GC4YPEY0LFXXXXXX. The National Highway Traffic Safety Administration Campaign 1D Number for this recall is 24V797. We can not get any answers from GM as to when it can be fixed. We use this truck for heavy towing constantly. We do not want to be in harms way. Can you help resolve this problem?

1. Transmission recall N242454440 Chevy 2500hd Diesel Silverado 2020yr. Jan 2025 valve body inside transmission was replaced, recall pending, parts not available, NOT DONE. 2. Currently having this issue but no recall information found for my Vin...The "P22F9" engine code on a 2020 Chevy Silverado 2500 diesel indicates a recall related to the NOx sensor, specifically a "slow response" issue with the sensor, which the Engine Control Module (ECM) might not properly detect; this recall requires a software update to the ECM to address the problem. Key points about this recall: •Affected vehicles: Primarily 2020 Chevrolet Silverado 2500 and 3500 trucks with diesel engines, as well as similar GMC Sierra models. •Issue: The ECM may not accurately identify faults with the NOx sensor, potentially leading to emission issues and reduced engine performance. 3. P1089 fuel deceleration problem, several repairs were done but problem still persists. GM engineer's told dealership having problems with computer duplicated codes in memory. Engine light goes on and off over 50,000 miles, vehicle runs great and no gas found in oil. At one point engine light was off for 14,000 miles. *P1089 should definitely be a RECALL ITEM! MISC: Yes available for inspection. No safety problems as of yet. All repairs were done at dealerships and confirmed by dealership. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO * I have contacted GM management staff in Michigan Mr. Craig Gidden, senior executive liaison, which referred me to CA customer service and supervisor, all to no avail, absolutely horrible customer service! They did not want to provide their contact information etc. *Contacted the GM arbitration department, they provided a case number but will not provide or respond to my emails for supervisor and GM legal department information.

In 2024, I noticed that my truck was experiencing rough shifts. It felt as if the back wheels were jerking over uneven ground, even though the vehicle was on a flat surface. In November 2024, my sister sent me an article about General Motors' massive recall due to rear wheel lock-up, which increased the risk of crashes. I contacted GM and learned that my truck was part of the recall. I reported the issues my truck was exhibiting, and GM instructed me to reach out to my dealer about the problem. However, I was informed that they did not have the parts to fix the issue and had no idea when they would receive them. I asked GM if they would provide me with a rental vehicle, but they declined, stating that if they offered a rental to me, they would have to provide one for others as well, which was not feasible due to the large number of affected vehicles. I explained that my truck is my daily driver for work, and I frequently transport my grandchildren in it. Driving the truck was hazardous given the issues it was already exhibiting. I was told to contact my dealer, and since my truck was under warranty, they should provide me with a rental. When I requested to speak with a manager, I was informed that they would only reiterate the same information. I then contacted my dealer, Sapaugh GM Country, located at 1435 McNutt St., Herculaneum, MO. I was informed that they do not have the parts. but they did a minor tweak which has caused more damage to my powertrain and engine.
