2020 Chevrolet Silverado Complaint Log

My vehicle has an incomplete recall, I am not getting what I paid for, still under warranty, not living up to GM Chevrolet warranty. Doesn't feel safe to drive.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while activating the rear window defroster, there was a crackling and sizzling electrical sound coming from the lower section of the windshield were the electrical components were located. The cause of the failure was not yet determined. The manufacturer and local dealer were contacted but no assistance was offered. The failure mileage was 49,000.

The engine is blown. Our GM Dealership where we purchased it, inspected it and says the engine cannot be repaired and must be replaced. And independent garage gave the same diagnosis. Went from running fine one day , to bucking and stalling in traffic causing a hazard to everyone on the road. Check engine light, check brakes, stabilitrak, ALL the lights on the dash were on like a Christmas tree. It doesn't run now. Currently sitting in our driveway now unable to be driven for three months as we don't have $10,000.00 for a new engine, and the extended warranty we purchased through the dealership expired 4 months before it blew up. We are now making loan payments on a GM vehicle that did not even last the length of the loan. Seeing a report on this exact issue, we did not even know until today that there was a place we could send in a complaint to. You are welcome to inspect the truck, but you would need to come to us, as it cannot be driven. Where can we get any help with this? Please help.

Main bearing on crankshaft when out

Engine start to make noise while driving Took my truck to a auto shop Mechanic said that it is a fabric defective engine

Rear end went out within drivetrain warranty period. Chevy claimed it was due to a leak even though there was no evidence of one and they couldn’t produce the part. Almost immediately after getting it back it started to have transmission problems (8L90). They again claimed there wasn’t a problem. The truck now has 120,000 miles on it and we are replacing the transmission after it would drop gears and, finally, wouldn’t go into reverse.

While the vehicle was in operation, the drivers side mirror fell off. The is a safety risk as I was not able to use mirror to check for vehicles in blind spot or in left lane as I was driving. Not to mention, as per NYS vehicle and traffic law, vehicles have to have at least a drivers side rear view mirror while in operation. After the vehicle was parked, inspection of the mirror assembly found severely corroded swivel and corrosion on the bolts holding mirror on the truck.

While driving on the freeway the right control arm broke.

The truck caught on fire while I was returning from a trip out of state and then it appears it came from underneath either the transmission the engine or electrical. While returning home a message came on the panel on the highway, saying transmission, hot idle run I pulled off and did this and after about 15 minutes, the message light went off and I pursued Coming home nothing was wrong with the truck. After I dropped off to the passengers, I was on the way home and turned on home road and the message came on that says truck powering down all the lights came on the dashboard. I put the truck in park and shut the engine off had a manly open the doors and got out and smoke was rolling from underneath the truck. I grabbed the cell phones and told my passenger to call 911. I went back into the center of the cab to grab something out of the center council and flames came from underneath the hood up the glass of the windshield right in the middle of the truck. Backed away I called 911 again. Troy fire department responded in about six minutes. The truck was engulfed and gone. Ohio state patrol give me a claim number of [XXX] the instant [XXX]. There has been no problem with the truck or vehicle during the time I owned it. It was regularly service. It had 109667 miles on it. The truck was a 2020 Silverado from Bill Harris Ashland. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On September 21, 2024 my Chevy 1500 series truck in the year was 2020. It was made caught on fire white driving it. We were returning from a trip pulling a trailer from Kentucky to Mansfield Ohio when we were on the highway. The transmission light/panel came across and said transmission need to engine idle. I drove it about 3 miles and pulled off on an exit at a gas station and did what it said after proximately 10 minutes. The message went off and cleared. we resume going home on our trip and we are 14 miles on the highway then we got off on our exit there’s no lights or no problems with the vehicle. I dropped off the first passenger and Lexington, Ohio, and then the second passenger lived about a half mile away , this time kept unloading their equipment. From Lexington to my home in Mansfield, Ohio the other passenger I was talking about the light transmission was weird and might’ve been just a sensor. As we pulled onto Home road all the panel lights started flashing and then a message came across and said engine is shutting down. I put in park off the engine, we exit the vehicle and smoke was coming out from underneath the truck. I reached into the center council to grab the cell phones and had faster call 911 and when I reached back into the truck were coming out from underneath the hood. I notified General Motors on September 23 and have been battling them to get an inspection done. after several months, they have finally agreed with insurance company on terms to investigate what caused the fire. That inspection is to Take Pl., December 4, 2024. I have recently just seen the recall article on GMC that came out on November 13. My truck is listed in the article as far as your make and model. This was a transmission problem that GM is trying to ignore and should be held accountable. Have video of when it caught on fire and how quickly it burned up.

The Electronic Steering assist stopped working while I was driving to work. Was leaving a stop sign and steering wheel became stuff and notifications on dash appeared. Was able to get to side of the road and turned vehicle off for 20-30 mins and started back up and steering was normal. Notifications on the dash were: Service Power Steering and Service Trailer Braking System. Search online showed this is a known issue that has happened with these vehicles for years and clearly hasnt been addressed. This is very dangerous. Vehicle has 42k miles on it. I had the "Service Trailer Braking System" notification come on a couple times previously and steering felt "sloppy" but immediately went away. And Ive never used the trailer braking system so I didnt think anything of it.

I was driving the vehicle but it sounded like it was popping when I would turn and when I shifted gears. As a result, my brakes were not working and I almost hit another vehicle. I took it to the dealership where they claimed they fixed the issue. When I picked it up this past Saturday, within a block of the dealership, the truck began shaking and a rattling noise could be heard. I had to take the truck back to the dealership. The truck is at the dealership where it is supposed to be inspected again and hopefully properly fixed.

At roughly 146,590~ miles the truck began making a knocking noise while driving at any speed, complainant had the truck towed to independent shop and was evaluated. Was told by shop that the engine can shaft pitted and engine metal shards had exploded and shattered throughout the engine. Making the opportunity for engine stalling or risk of fire/ smoking while operating the vehicle extremely likely. Complainant was told there was no access to engine replacements or parts at this time and the wait time to receive one was 4-6 months. No warning lights ever went off. Engine was eventually replaced entirely when the part became available by an independent service dealer.

Summary: While driving, the transmission intermittently fails to shift and the truck has locked up and screeched to a complete halt approximately four times, creating a sudden stop/near rear‑end‑collision risk. Details & timeline: First symptoms were around 55,010 miles. On 10/13/2024 the Chevrolet dealer performed “SERVICE TRANSMISSION GM” (fluid & filter), but the condition continued. In April 2025, a shop documented DTC P0700 & P2727 (pressure‑control solenoid), burnt transmission fluid, and clutch material in the pan, and recommended replacing the transmission, transmission cooler, and cooler lines. Earlier, the transmission control module was reprogrammed, and oil cooler lines were replaced, but the truck still intermittently fails to shift while driving. The check engine light has illuminated during some events. Engine safety concern: During the same period the engine oil was found very low/“no oil on dipstick” with no external leaks; an oil‑consumption test was recommended, raising concern about internal engine damage and possible contamination from the transmission failure. Safety impact: The lock‑up / abrupt stop events occurred while the vehicle was in motion at approximately [~speed and road type, e.g., 35–55 mph on city/secondary roads], forcing hard braking by vehicles behind me. This presents a risk of sudden loss of propulsion and crash. Frequency: About four lock‑up events so far; shifting failures are intermittent and ongoing. Current status: Vehicle at ~73,000 miles. A Chevrolet dealer is being asked to perform a factory diagnosis and to submit a manufacturer goodwill/warranty review.

I'm beginning to have similar problems with the 6.2 ecotec3 engine that gm has known problems and hasn't recalled them. Dealer indicates metal shavings from the main motor bearings. Just like others I will experience a total motor failure at anytime. This will be catastrophic if motor fails and shuts down. I fear I will be rear-ended or not be able to get out of harms way. This has happened to many with the same motor. Why would there not be a safety recall on a known safety issue. Others affected have been injured even killed because there vehicle just stopped in the middle of a roadway. I currently fear for my families safety and cannot simply opt out of a vehicle with only 18,000 and thousands invested. Instead it sits waiting for the right thing to be done. To be repaired to safely use. Thank you kindly.

Vehicle has been in and out of service for the past 5 months with multiple alerts including "Brake system failure 43mph top speed," "service esc," "service brake assist." On major interstate car would not accelerate past 43mph putting myself, infant, toddler, and wife in danger. Multiple attempts have been made to repair the vehicle and nothing has been successful. Lifters, CAM, torque converter, EBCM, master cylinder, calipers, and the list goes on. When this happens the brake is extremely hard to press making it difficult to stop the vehicle. Issue has been reproduced by dealer and attempts have been made under warranty to repair. Car only has 36k miles on it and the issue began prior to that. GM ongoing solution is to bleed the brakes, which clearly has not resolved the issue. Still hear ticking and noises from engine. Something needs to be done to remedy this issue. This is a safety hazard for myself, my family, and everyone driving around me.

Bad shuttering, slow acceleration, clunking noise, check engine light flashing all started while driving home. Took it to a transmission shop and they said it was the TC and transmission. I then called the dealership to see if there was a recall, and looked up any recalls. Since I have had fluid flushed and changed, and still have the problems. This has been an on going problem for a couple of years now. It was just out of warranty for dealership to fix. It started while I was on a highway and had very poor acceleration control.

2020 Chevrolet Silverado 1500 Custom, bought new on August 10, 2020. On August 24, 2020 I returned the vehicle to the dealership with 524 miles on the odometer, for hard downshifting at low speeds. The technician returned the truck with 531 miles, stating that he could not duplicate the issue. The issue continued along with occasional shudder at speeds around 40-50 m.p.h. On December 14, 2022 I took the truck to a different dealership with 1,616 miles and it was returned with 1,625 miles on the odometer. The technician found a slight shudder at 25-30 m.p.h. under light acceleration, but could not duplicate any other malfunction. The technician stated there was no metal debris in the fluid pan and performed a flush and refill of transmission fluid, installed updated thermal bypass valve and three seals. The issues still persisted, but not as harsh or as frequently prior to this service. I returned to the original dealership again on September 3, 2020 with the same concerns at approximately 28-K miles. Again, after having my truck (4) days, the original dealership's technician stated that he could not duplicate the problem(s).

At approximately 68K miles, the torque converter failed. Luckily it started going out and we could feel it. It would surge/shudder while driving on the road. We had to have the torque converter replaced at $5k. A dealer replaced the parts. At approximately 90K miles, the lifters started making a loud pinging noise. It turns out the lifters had issues which lead to them being replaced along with the camshaft. It could have failed on the road and left us stranded. The sound of the lifters alerted us. A local shop fixed the issue at a cost of $9K.

Fuel pump module failure. Car stop working while driving. Immediately downshifted to a lower gear and would no longer drive above 10mph without shutting down

Lifter issues, loss of power, flashing check engine light

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the vehicle was jerking. Additionally, the contact stated that upon starting the vehicle and attempting to shift into gear, the vehicle failed to respond. The check engine warning light was illuminated. The vehicle was towed to Razorback Transmission Services, where it was diagnosed that the transmission had failed and needed to be rebuilt. The vehicle was repaired. The contact related the failure to an unknown recall. The manufacturer was contacted for reimbursement assistance and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 175,000.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the tailgate opened independently without warning. Upon investigation, the contact discovered NHTSA Campaign Number: 24V060000 (LATCHES/LOCKS/LINKAGES) and linked the failure to the recall. The local dealer was notified about the failure, and the contact was informed that the VIN was not covered under the recall, and the contact was provided with an estimate for the repair. The manufacturer was also notified of the failure, but referred the contact to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 50,000.

While driving 55+mph on a parkway the service parking brake, check engine light and the traction control light came on with a warning "Engine Power Reduced" which was dangerous because I could not accelerate and there was not a spot to pull over. This is frustrating due to the fact that I was having this same issue 6 months ago and Chevrolet said it was a wiring issue and it wasn't covered by the warranty because it had 42k miles. Chevrolet said it was a known issue but it was not at the level of a recall and it cost $1800 to fix.

Truck was purchased from an authorized chevy dealership less than 6 months ago. Truck had transmission service just before purchasing it as it was *maintenance* not repairs. However all of a sudden the truck will stop accelerating in the middle of intersections where you typically would have a 1-2 or 2-3 shift. along with during acceleration on highway it will decide it doesnt want to shift anymore to a higher gear than 4th or 5th. This is causing a constant safety threat as i cannot control when the vehicle will move under its own power. This is a known problem with cheverolet as they will replace the parts that cause this if its under warranty however mine is not. Although the warranty is up the issue is caused by poor manufacturing process and they know that.

THERE IS A KNOWN ISSUE WITH KNOWN LEAKS AT THE REAR SPOILER/ 3RD. BRAKE LIGHT. DUE TO THIS LEAK, THERE IS AN ODOR IN THE VEHICLE CAUSED BY MOLD OR MILDEW WHICH IS CREATING BREATHING AND ALERGY ISSUES. I RECENTLY HAD OPEN HEART SURGURY AND THIS IS STARTING TO EFFECT ME TO THE POINT I CAN NOT BE IN MY VEHICLE WITHOUT THE WINDOWS ROLLED ALL THE WAY DOWN. AND I GO INTO SNEEZING FITS WICH IS A SAFETY CONCERN

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the vehicle was shaking and vibrating abnormally. There was no warning light illuminated. The contact stated the failure was a recurring failure. The vehicle was taken to a local dealer and the contact was informed that the oil level was low, and oil was added. The dealer had not diagnosed the vehicle. The contact stated that the failure reoccurred. The contact had been checking the oil level and was constantly adding oil. The contact stated that the same dealer had changed the spark plugs and fuel injectors in January 2025. Recently the contact was unable to start the vehicle, and the vehicle was towed to the same dealer. The vehicle was not diagnosed; however, the dealer advised that the failure might have occurred due to a failure with the transmission. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was 136,888.

I began having difficulties with my transmission at around 75,000 miles. The transmission began to stutter and slip. The transmission felt like I was driving on rumble strips. Transmission was replaced after waiting approx. 4 months. The transmission was replaced with a new GM transmission at the dealership.

Our 2020 Chevy 1500 Trail Boss was waiting for an ordered instrument cluster at service department. The surveillance camera, film the vehicle catch on fire after being parked for 2 days. The smoke started from the inside, and the vehicle engulfed in flames until the fire department came. After the fire was extinguished very little was left of the vehicle. Basically a frame and engine was the only thing left. The vehicle had a little over 70k miles.

While changing a blown fuse for the instrument cluster, my truck unexpectedly caught fire, endangering my safety and causing significant damage to the vehicle. The fire started behind the passengers side fuse box within the wiring harness (GM# 84717166). The dealership determined that the failure was due to wire harness chafing on the thread side of a tie bar bolt. Due to General Motors not responding to their request for repair information via the TAC, they concluded that the bolt needed to be shorten in order to reduce the chafing. There were no warning signs or indications that this was going to or could occur. The burnt harness is available for inspection but the vehicle has been traded in due to no longer trusting how it was manufactured.

SERVICE POWER STERING AND SERVICE ESC WARNING LIGHTS CAME ON, LOST POWER STERRING. AFTER 30 MINUTES RESTRATED THE TRUCK AND EVERYTHING WAS FINE. TOOK TO CHEVEROLET DEALER, THEY FOUND NO CODES AND COULD NOT DUPLICATE THE ISSUE, HAD NO SOLUTION FOR HELP, TOLD TO BRING BACK WHILE ITS DOING IT, YOU CAN NOT DRIVE IN THAT CONDITION. VEHICLE HAD 16,880.00 MILES ON IT WHEN PROBLEM OCCCURED,

The back window is leaking water into the cab. Water enters the cab any time it rains or when washing the truck. This water is creating a damp environment by soaking into the back of the seat, the carpet, and the headliner, creating the potential for black mold. Immediately after purchasing the truck, the dealership had me bring it back in so they could fix it. Ever since the repair from the dealership, the window has continued to leak at the same rate that it did before the fix.

Power steering stopped working while making a left hand turn. Pulled to the side of the road, turned off engine. Looked in Owners Manual, no mention of electric power steering, or where to put steering fluid. Restarted engine and steering worked. Went online and found possible chassis/frame ground issue. Ground cable on RH side behind front tire was corroded badly. Went to the dealer for a new ground strap, the dealer had 1 right under the counter. new strap appears to be plated, is this a known issue?

While driving down road at around 60mph 6.2L engine started to make loud knocking noise and shaking violently while loosing all power. Truck had 79,797 miles on it at the time with all oil changes and service done at GM dealership. After having GM dealership diagnose truck, it was determined to have a spun rod bearing, causing multiple other engine components to fail. Truck was not under factory warranty and was quoted $12,200 to replace. There were no warning lights or any known issues until this incident.

Vehicle is burning oil. I drove 300 miles and had a low oil message pop up. Vehicle still had 50% oil life left.

We went to an appointment and when we got back in the car, a message was on the screen. It said that the brake system has failed and we could only drive 43 mph maximum! The engine light was on and we could not accelerate beyond 43 mph. This is extremely dangerous when driving on a highway! We drove home on the interstate going 43 mph in a 70 mph zone! We had small children in the car and almost got into a few accidents due to other aggressive drivers. We then called local dealers who said that they were too busy to take our truck for weeks! They also said that our truck was not covered under warranty. So we took it to a local body shop. They fixed it for just above $500. It worked for a week and broke again, then they fixed it again for free. The brake failure 43 mph light came on for the 3rd time. We took it Garber and they fixed it after 2 weeks and charged us a fortune. Invoice attached. A few weeks later the same light came back on. Garber then took another 2 weeks to fix it! I’m writing here as I’ve seen other silverados recalled for the same issue but not my exact truck (year). It’s obviously faulty software and it should not be the customers responsibility to fix. Especially with a vehicle under 20k miles! There is absolutely no way that we will ever buy a GM again but the important part here is that other people are not put into a dangerous situation like we were. Besides dealing with this issue for well over a month - the important part is safety. I can’t understand how these trucks have the same problems but only certain VINs qualify for a recall. Please consider our truck as part of the overall recall for this issue. It’s unethical to pick and choose only certain VINs!

Engine (v8) lost power and made terrible noise at 72,000 miles. Dealer installed a remanufactured engine and charged me $5109 and took 12 weeks to complete the work. GM claimed there were “unaware” of any issues with these engines even though an internet search showed tons and f people with the same problem.

While driving on the interstate, my entire display panel/information queue lit up and my information display issued crazy and bizarre warnings. When this happened (I was traveling around 60 mph) immediately pulled off on an exit only to find that my brakes were out/nonexistent and my emergency break button not responding. Luckily and by the grace of God, there were no other vehicles or pedestrians in my line of travel on this exit, the exit fortunately happened to be on an uphill incline/climb which aided in slowing my truck to slow down to a complete stop, and neither I or any other person or vehicles were harmed during this incident. Was told by the Jim Ellis Chevrolet of Atlanta Chevrolet Service Manager (who by the way was a great help and resource through all of this) informed that there was a software “glitch” that had caused all this to happen. I never was told of or was informed of any software “updates” nor had any Chevrolet Dealer Service Department updated this software “glitch” when my truck was given to them for all GM mileage-tiered full service recommendations.

While driving brakes failed and codes came on saying brake system failure 43 mph, this problem apparently is a programming issue that will cost over 600 dollars because “reprogramming” isn’t covered. Brake pads were over 50% life and it is a very dangerous error.

Problem started while driving on the highway, I was speeding up from the ramp to merge into the highway. As I got to 62 mph the dashboard started blinking that i could only go up to 62 mph max. Cruise control was not on. I drove to my destination at that speed with the message on the dashboard. I arrived at my destination, parked, turned it off, a couple of hours later turned it on to drive again. At this point, the dashboard message was that I could only drive it max speed 42 mph and "service tire monitor system" I towed to my mechanic given i could not drive at that speed on the highway back home. The mechanic said it was time for a brake change and that might be the issue. He changed all the brake pads and rotors and the truck drove fine again for less than a week. As i was getting on the highway, the truck started to jerk like it wanted to stop as i was speeding up, i was going 45 mph. There was a clanking sound coming from the engine. Then multiple things started flashing on the dashboard; check engine, traction control, messages reading "service parking brake" and "service ESC" I turned the truck off for a couple of minutes on the highway shoulder. Turned it back on, the same messages were still on the dash. I again could only drive it max in the 40's mph. The faster I tried to go, the more heavy and forced the truck felt. I had to park it over night in a parking lot. The next day i scheduled an appointment with a mechanic in town who checked it and said i would be needing a new engine, that he had seen this same problem a couple of weeks ago on a same truck. He quoted me $9K.I towed the truck back home and had another mechanic come take a look at it, he was getting the codes 0P50D and P0304.He exchanged the 4 cylinder for the good 1 cylinder to see if the codes would change from #4 to #1 and it did not. He said the issue was internal at that point and suggested I go take it to the dealership under the warranty. Its not under warranty, it ended at 60K miles and I have 80K now.

I have a 3.0 LTRe Dura Max issue is if the (Timing Belt ) or actually the oil pump drive belt breaks the engine will lose power if this happens in the middle of an intersection or major highway you will loose total power

The 10 speed transmission suddenly downshifts when slowing down. It goes from like 8th to like 3rd suddenly and the rpm’s shoot way up. The wheels do not skid on pavement but will be an issue when the roads get slick here in West Virginia. This is a serious safety concern. This has happened many times since I purchased the truck. The dealer in the past has told me the transmission needs flushed. But now I’m seeing that there is a recall for new transmission software. I would like to have this update please before the roads get slick from snow and ice.

The tailgate opens up while vehicle is in drive. No warning lights come on, the only way I knew is that people driving beside us flagged us down. The pickup bed was full of our luggage… luckily, nothing fell out. This has happened at least 3-4 times. The last time, we were towing our travel trailer, the tailgate opened up while we were driving and got caught on our tongue jack and propane tanks…damaging the tailgate and propane tanks.

During driving at low speed 15-30mph with 4 wheel drive set to auto. 4 wheel drive engaged and rear wheels locked up. Turned off 4wd no issue. Upon arrival at the dealer a bad sensor was determined to have caused the rear wheels to not perform as designed. After resolving the issue now I hear rubbing metal noise from the drive shaft. Spoke to Chevy about the issue haven’t heard back.

I took my truck in for an oil change on 5/25 and 12 miles after words, my truck was thrown into reduced engine power mode, which dropped my speed unexpectedly as I was driving. Luckily, I was in a residential area so that did not affect my safety, but there is potential that someone could have this code come up on the highway and have their vehicle unexpectedly throttled in regards to speed. The reduced engine power mode was the result of a code related to an electrical issue that ended up being the coolant control valve for the engine. I took it to a Chevrolet dealership that did the oil change, and they inspected it and determined that that part was faulty And would need to be repaired. The problem comes intermittently because The dealership drove my truck some and the issue would occasionally go away. As the part needed is on a seven month back order, the vehicle is available for inspection if needed.

PIP5921 Bulletin.

“Service power steering soon” message appeared and I took it to a Chevrolet dealership and I was informed I needed to replace the power steering module for a total of $2300 for parts a labor. Now the power steering will randomly stop, making it almost impossible to drive. There are hundreds of threads online of this model having the same issue and this should be a recall because someone is going to get injured.

The check engine warning light was illuminated. The contact was able to pull to the side of the road. The contact was able to restart the vehicle and drove to the nearest independent mechanic, where it was diagnosed that the engine had experienced an internal failure. The mechanic determined that the crankshaft, the lifters, an unknown valve, and other unknown parts needed to be replaced. The vehicle was repaired. The dealer was not notified of the failure. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 79,000.

The rear third brake light spoiler leaks causing damage to my headliner and vehicle. I have researched this and it appears to be a known issue to GM. However, GM is saying that my vehicle is not affected as of yet. I had an estimate completed on the vehicle by a local body shop. They believe the issue involves the spoiler assembly nuts not being properly tightened and sealed by the manufacturer. A repair will cost approximately $593.63.
