2020 Chevrolet Silverado Complaint Log

Total engine replacement at 62k. The junk lifter system government regulation has compromised our Vehicles. Active fuel management systems are used expensive trash changes to our American motors that generate extreme hardship for single vehicle owners.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at approximately 70 MPH, the “ESC Unavailable”, 'ABS Failure', and “Do Not drive over 62 MPH”, “Please Drive with Care” messages were displayed. The contact stated that when the brake pedal was depressed, the brake pedal remained on the floorboard. The contact stated that the braking distance was extended. The vehicle was taken to a dealer, but the failure was not duplicated. The manufacturer was notified of the failure. The failure mileage was 67,699.

While traveling on a rural state highway, the #8 lifter bearing failed, causing the engine to lose considerable power and the dash light to come on. No advanced warning of engine problems was noticed prior. The transmission also went into limp mode not allowing the vehicle to shift gears. At the same time the ABS and ESC systems also went into a safety mode diminishing the stopping power of the vehicle. Upon inspection by a licensed mechanic it was discovered that the #8 lifter bearing and the camshaft were both damaged at that time. Total replacement cost was over 10k and it took almost 6 months to find a rebuilt L87 engine at that time because there was almost no supply available as a result of these engines having multiple failures nationwide

Check engine light came on, I plugged my code reader in and was given P0498 ERROR CODE. Upon doing research and calling around to 3 different Chevrolet service centers I was told that it is a know issue with the fuel pump control module on all gm trucks. I am part of a truck group of over 150 and 85 of us has had this issue and all are currently waiting for the part to come in which is back ordered over months. Why has there been no recall and service bulletins yet if all 3 of the service managers agreed of the known issue.

Water leak above the rear sliding window has soaked into carpet & upper roof inner lining panel.

A/C blower motor over heated and caught the electrical wires on fire under the dash. I had just left my house for work about 1 mile from home and the dash started smoking then a fire started under the passenger side glovebox parked the car in the middle of the street and I was able to exit the vehicle and put the fire out with a half bottle of water I had in the car. I then called 911 and I believe it was EAST Pierce fire department. They shortly arrived and confirmed it was an electrical fire and that there was no more heat coming from it. The fire department then gave me A ride home. The vehicle has been towed to Sunset Chevrolet in Sumner Washington where the Vehicle was purchased New in 2020.

I purchased my vehicle from Southern Pines NC and at the time it had 12k miles on it. At about 40K I started having transmission problems. It would hard shift in 1st and 2nd gears. It also would not go into reverse. Hendrix Chevy had my vehicle multiple times attempting to fix things. Telling me it was not the transmission etc etc. My power train warranty expired at 60K. I have asked for my complete service records multiple times. I have paid out a lot of money due to it "not being the transmission". The last time it was there the manager Matt took it home and said the changed the transmission fluid which was very dirty. Almost trying to say I had done something to make it that way however in the service history they had it almost the entire month due to issues. I got it back and my brakes went out while driving. I was able to cost to a stop. I was at my limit. I called Matt and said come and get this vehicle. I want Chevy to take it back. They kept the vehicle for almost 2 weeks. Matt said he personally drove it home and it was fixed. I picked it up and I have not had any issues for about 8 months or. Now my power train warranty is expired and my vehicle is again doing the same things it was when I took it in at 40k. It now has 85k. It is hard shifting in 1st and 2nd. It is rolling when in drive. I also have had many body parts that have come off etc. I called Chevy today to again get my service records. I stil have not gotten them. I just want a reliable vehicle. I feel like I have not had a reliable vehicle from day one. I want them to take this vehicle back and I want a Toyota hat is comparable in cost of my truck in its new form. Can you help me?

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that there was an abnormal odor of raw fuel in the cabin of the vehicle. There was no sign of a fuel leak. There were no warning lights illuminated. The contact had to roll the windows down while driving. The child in the vehicle experienced a headache but medical attention was not provided. The vehicle was taken to the local dealer, who informed the contact that there was no recall on the vehicle for the failure. The vehicle was not diagnosed or repaired. The contact stated that the failure was related to NHTSA Campaign Number: 19V837000 (Fuel System, Gasoline). The manufacturer was contacted. The failure mileage was approximately 67,500.

The engine seized unexpectedly and without warning during driving. Being sudden and without warning it risked the occupants of the vehicle being injured as they struggled to get off the road and out of harms way on the road. The vehicle was taken to the nearest Chevrolet dealer to be inspected where we were told that the engine had suffered a total engine failure and would need to be replaced entirely. The vehicle WAS inspected and damage confirmed by the dealer at that time. Prior to the failure there were no warnings of any kind.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while the vehicle was parked inside the garage, he noticed a crack on the frame and there was water running back into the interior of the cabin and the backrest of the seat. There were no warning lights illuminated. On a separate occasion, the contact experienced water entering the cabin while it was raining due to the frame cracks. The contact contacted the water doctors and provided a diagnosis of frame crack in multiple locations, allowing water to enter the cabin of the vehicle and underneath the spoiler. The local dealer was contacted; however, the vehicle was not repaired because it was not under recall. The manufacturer was made aware of the failure. The failure mileage was approximately 40,000.

I just saw a recall for 2021-2024 vehicles for connecting rod/crankshaft engine components. I am not 100% sure that i have the same problem but my warning signs are the same. For example, there is a knocking sound in engin, it shifts abnormally and it hesitates and has reduced propulsion. I talked to several other Trail boss owners that had to have their Lifters repaired so maybe it is that? These problems are happening to everyone prior to even hitting 70k miles. I cannot afford to fix this if it is a problem that shouldnt be happening in the first place, due to crappy manufacturing.

fuel pump control module (13540028) went out no open recalls however they are national back order with no eta so this is an ongoing issue... SO NOW NO TRUCK FOR MONTHS AS THEY TELL ME ITS ON INTERGALATIC BACK ORDER.

When you try and start the truck, the instrument panel lights up fully but when you push to start the instrument panel dims and acts like the battery is dead and won’t crank. The engine light is on. After a few presses, it finally cranks and starts fully. Has happened repeatedly and randomly.

Notice the engine temp was rising, had notice I was slowly losing coolant in my overflow tank. Then while driving it started making noise that the engine overheated need to idle vehicle then as I pulled to a stop light the rims bogged down the whole vehicle shut down The radiator has a small leak in the plastic reservoir on the driver's side of radiator. Could have cause a big problem if I was in traffic when it shut down cause I had no control to turn the wheel or anything else once that happened.The vehicle got extremely hot very fast.

Brake system failure reported on screen. Extremely hard to stop vehicle.

Transmission shudders and has a delay in shifting/starting movement of the vehicle. This problem was noticed at 98k miles about a thousand miles after I purchased the truck from a dealership. It has been inspected, and repairs scheduled, but the transmission is still on back order after 5 months of waiting. No part ETA is available from Chevrolet corporate. This issue is a safety concern due to the fact that the vehicle could hesitate to accelerate in the event of needing to take evasive maneuvers to avoid an accident/road hazard.

The trucks installed trailer wiring can cause a traffic accident. The wiring harness is known to have electrical issues but is not being corrected under warranty. It is difficult to know of these issues until you hook up a trailer or camper. The trailer's brake light and turn signal are affected by the faulty wiring. The dealer narrowed the problem to being between the plug and fuse. Other people have voiced their concerns with the trailer wiring.

6.2L V8 had catastrophic failure due to lifters failing while driving at highway speeds.

Rear window leaks

The DEF system tank and heater tube/wiring assembly need to be replaced due to the wiring melting. There should be larger wires or a fuse to prevent this. The system is tied to the Emission Controls system in the vehicle. When this happened I was warned on my dash display I had only 165 miles remaining at 65mph, and presumably slower thereafter. I live in Alaska, we travel long distances, sometimes in extreme cold temperatures and always far from help; even cell service if away from urban centers. I find it unacceptable my truck can decide to strand myself and/or family (3 children under 5) based on emissions, not run-ability. The temperatures in Alaska have been severely cold a couple weeks ago when this issue came up. The issue is confirmed by the dealership and is a known issue in the diesel community. Apparently it is a known issue for diesels in cold weather. Diesel is common in cold weather so the issue is perplexing at best. The vehicle has never been inspected by any one other than myself, a mechanic and the dealer. There were no warning lamps, only the dash warning the emission system needed service.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at various speeds or at a complete stop, the vehicle jerked while depressing the accelerator pedal with the check engine warning light illuminated. The vehicle was taken to several dealers where the spark plugs, engine wiring, and other various parts were replaced; however, the failure persisted. Upon investigation, the contact discovered NHTSA Campaign Number: 24V797000 (Power Train); however, the VIN was not included. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 87,500.

Purchased a 2020 Silverado 1500, 5.3L 4x4 with 8,000 miles. Now at 66,000 miles the torque converter is bad. Shudders, hard shifting, lunges into gear, won’t go into reverse at times. MULTIPLE complaints with these engines. There’s a recall, but it stops at 2019….. WAKE UP GM!! This problem is still ongoing from 2020-2024!!! Needs to be another recall

Driving 20 mph on paved downtown street when cross arm failed causing wheel to twist 90 degrees causing damage to brakes, drivetrain, abs, and steering. No warning just pop and trying to maintain my lane before able to turn into parking lot. Towed to dealer and diagnosed with control arm failure. They are aware of this issue and now replace control arms stronger rough country control arms and level the truck differently. DeAler is claiming GMC will not cover and they are calling it a suspension issue and out of warranty two months. Truck has 26000 miles on it. Lucky event happened at 20 mph and I was able to maintain control of vehicle

In November 2023 my check engine light suddenly started flashing, my service parking brake light came on, traction control light came on and service ESC message was on the DIC. Then my truck started running really rough. At the time I was going roughly 10 mph. I took it to the dealership and they found a lifter had failed. My truck was at the dealership for a month. Fast forward to now, February 2025 and today I got the exact same lights appear on my cluster and same message. I was driving approximately 50 mph and my truck felt like there was a lack of power and there was hesitation in the engine.

The rear power sliding window in my 2020 Chevrolet Silverado 1500 LT leaks whenever it rains. The leaking water enters the cab and runs down the back interior wall of the crew cab and saturates the insulation material and the carpeting on the floor. The moisture has caused the seat brackets that attach the seat to the truck to rust and it has also caused mold inside the cab. I purchased a DIY mold test kit and it was positive for mold. My kids and I have allergies and this is causing issues with our health and if it continues it could cause serious health problems. This known issue of the leaking rear window is very widely discussed on many different gm truck forums and internet sites yet gm will not take ownership of this obvious problem.

Today while driving , the upper ball joint separated from the control arm, causing the truck to pull hard to the right. I was able to keep from wrecking the truck. While doing research it seems that this is a common occurrence with the Silverado Trail Boss and the Sierra AT4. I read a safety recall report on these vehicles, 21V-718, after reading this, it's exactly what happened with my truck. Ball joints is rusting and corroded. Vehicle is able to be inspected upon request. If I had been on the freeway traveling, it would have caused a severe single or multiple car accident as I lost control to steer. No symptoms leading up to the situation.

torque converter and transmission. For more than a year truck would lunge or jump forward when stopped at light or sitting in traffic, brought truck back to dealer several times for this problem each time they would tell me nothing wrong with truck. problems continued to happen and Truck started hesitating when accelerating then jumping into gear also while driving on highway truck felt like it was slipping out of gear and RPMs would jump up. Brought truck back to dealer again 3 months ago and they said torque converter was going bad and they would call me when part was in. two months later and they kept saying it was back ordered, now while driving going down steep incline into busy intersection felt like i got rear ended by another car, when looking back no car was close me truck stalled and started rolling into intersection I slammed on brake and got truck started again only to find transmission had failed and it slammed into gear when accelerating put my flashers on and got off road . Brought truck back to dealer to have them tell me transmission was now gone. truck has now been sitting on dealer lot for a month now with them telling me they can't get parts or transmission to fix. Very dangerous situation with this transmission and them knowingly kept sending me away in this truck. I feel that they knew about transmission problem over a year ago when I was bringing it in for the lunging forward after coming to complete stop at traffic light and kept saying nothing wrong. Truck was still under original warranty and only has 62k miles on truck.

Vehicle would not start, had it towed to a shop and they said the engine locked up. After tearing motor down the main bearing was scored and there were metal scratches.

Truck shudders, with varying degrees of vibration, emtek applying brakes. It is especially rough when applying brakes on the highway as it feels like it could lose steering control. Shaking is also very noticeable at slow speeds. Have had rear brakes serviced and problem persists. As of this month, the "service ESC (electronic stability control)" light has come on, along with other faults on the dash. VIN does not indicate unrepaired recalls, but this issue makes the drive feel dangerous

I am writing this complaint to bring up the melting dashboard on my 2020 Silverado. I took my vehicle to Beaver Chevrolet in Jacksonville ,FL and they identified that there is an issue with my dashboard. However, they refused to fix or replace it. The service manager check his personnel vehicle and confirmed that his is sticky as well. My co-worker who owns a 2020 GMC Sierra also has a sticky dash. This issue is dangerous as my dash is very shiny and reflects everything onto the glass making it very difficult to see.

Started to notice water marks on the driver and passenger side rear window. According to online forms it is a common problem with 2019 and 2020 silverados with a sliding rear window. The dealer claimed it wasn't a safety issue, which I argued it was due to the mold. Chevy knew about the manufacturing problem before they even sold me the vehicle and did nothing to fix it
