2020 Chevrolet Silverado Complaint Log

Popping and/or Clunking Type Noise Heard During Hard Turns at slow speeds and backing up. Seems to be a problem with the control arm

Vehicle had several lights on dashboard and messages, service brake system,engine power reduced, service trailer brake controller, service esc, service power steering. Vehicle lost power steering and brakes were nearly all impossible to push…luckily I was near my house and got home safe, my family or myself could’ve been seriously hurt

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that there was condensation leaking from the rear window third pane. The contact observed discoloration near the condensation. The vehicle was taken to a dealer where it was diagnosed that the rear window needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 50,000.

Transmission shuddering and shaking while driving. Once in blue moon service light flashes for less than 1 minute then goes off with no diagnostic codes to show.

Airbags failed to deploy when I hit a deer going 50-55 MPH. There was a chemical smell after the impact but no airbags deployed,

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle experienced reduced engine power. The reduced engine power warning message was displayed. The vehicle was towed to the dealer where it was diagnosed that the rear main seal needed to be replaced. The dealer replaced the rear main seal; however, the failure recurred. The vehicle was taken back to the dealer, and the dealer replaced the rear main seal a second time; however, the failure recurred with engine oil leaking onto the ground. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 11,340.

ABS light came on during breaking to avoid an accident and did not break the vehicle at all. Now there is a alert on the Driver Information Center(DIC) stating a break system failure.

Right front wheel control Arm broke on the interstate running 70mph with no control.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that upon purchase of the vehicle, he noticed an orange-colored rust underneath the chassis of the vehicle. The salesman assured him that the rust would be cleaned off once the sale was finalized. Months later, the contact noticed the same orange colored rust had returned. Upon inspection of the vehicle, he discovered severe corrosion located in several spots on the subframe. The contact took the vehicle back to the dealer for the repair. The contact then received a call back from the dealer and was informed that no corrosion was found, the dealer linked the failure to structural rust. The contact disputed the diagnoses and the dealer agreed to have a further inspection performed on the vehicle. The manufacturer was not notified of the failure. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 65,000.

Power Train Transmission Torque Converter “Chevy Shake” Multiple symptoms. - Shuttering , “ buffeting” , slipping sensation. Continuous almost like “strong wind gust” or “head wind” - Humming, if you have ever heard a “high pressure” hydraulic equipment. - RPM bounces 300 to 500, but transmission does not “down shift” (while driving) - Vibration, of the truck can be noticed, felt at various speeds, 40mph to 60mph(shutter) almost like it struggling to get up to speed (unless heavy on the gas pedal) 70mph and above to say 80mph, then shaking, vibrations worse when coasting back to 70 mph Vibration will “not stop” until truck speed is drastically slowed or come to a stop. - Steering wheel “shakes” , “vibrates” also can happen at 60mph to 70mph and above to say 80mph, then worse when coasting back to 70 mph - “Clunk” when stopped and shifting into “reverse” (new development symptom) Vehicle is in for inspection. It keeps reading service break system. Service ESC

When accelerating the transmission shakes violently under the hood. It shakes so bad that other vehicles can hear it the vibration is intense until you take your foot off the gas and then try to accelerate again it happens a few times then it’ll stop until the next red light. Slowly accelerating makes it worse but doesn’t matter either way.

Vehicle developed a sensation at approximately 28,000 miles similar to driving over a rumble strip. At approximately 32,000 miles this was diagnosed as a failing torque convertor. There are TSBs related to this for the 8 speed transmission, but dealer stated no known TSBs exist for the 6 speed. The truck is currently in the shop getting the torque convertor replaced and should be available for pick-up in the upcoming week. Rumble strip sensation occurred under light throttle acceleration and presented more frequently on an incline. There were occurrences on flat ground, but this was not as common. The vibration occurred most often at highway speeds of around 70 MPH, but also occurred several times in the ranges of 20-30 and 40-50 MPH. Tachometer reading during these occurrences was around 1,500 - 2,000 RPM. Issue was intermittent and would come and go. Most of the time the sensation was mild, but periodically the vibration would be severe enough the driver felt like he had been rear-ended. A separate symptom would occur while going up hills and the tachometer would bounce up and down approximately 300 RPMs with a noticeable surging sensation. When presenting, the vehicle would surge forward every few seconds until the hill had been crested. This only occurred at highway speeds with cruise set and would not present when the rumble strip vibration was present.

I was driving down I27 10 miles south of Lubbock when my 2020 Silverado 1500 3.0 Diesel engine stopped accelerating. I was going 75 miles per hour and the truck just stopped causing trauma for me and my family we were lucky enough to get to the side of the road. I ended up calling gm roadside assistance and they sent a tow truck to pick us and the truck up. The truck wouldn't engage into drive nor reverse. Once towed to the dealership, Gene Messer Chevrolet, in Lubbock, Texas, a service tech mentioned that a ton of the lifters bending push rods are going out on the late 2019, 2020 model silverado due to cheaper lifters added to the vehicles due to Covid shortage supplies. In essence, they wanted to get these models out with no regard to safety of the consumer. I'm not pleased with the craftsmanship GM has lined out on these trucks, this could've ended way worst. They jeopardized my families safety for profits. Right now the truck is still awaiting diagnostics still won't drive nor reverse per dealer service tech. It's just a terrible situation, the truck is new only has 25,500 miles on it, this needs to be recalled.

After putting my vehicle in reverse, my backup camera did not come on and gave a warning that the camera was not working.

Shifting problems. Transmission feels like it is going to fall out. I have taken it in several times to be fixed and my Chevy dealer can not figure it out. Problem never fixed.

It seems the top suspension arm on my front passenger side broke.

Upon starting the vehicle for the second time one day, when placing the automatic transmission into 'D' - Drive, it began to roll backwards as if it was in Neutral on a slight decline and the brakes had to be applied to avoid rolling downhill backwards. After attempting to place it back into 'P' - Park and back into 'D' - Drive and attempting to try 'R' Reverse to try to get it to move forward properly, it would not go forward. After several tries and restarting the vehicle completely, it finally attempted to move forward but would only do so at a reduced speed and would not respond to the accelerator pedal beyond a certain amount. After trying again, it appeared to move forward a bit better, but then upon stopping at a stoplight and attempting to pull out for a left turn onto the road, the speed again was reduced and I had to immediately place it into 'R' - Reverse to avoid an accident due to oncoming traffic. Finally I was able to get it to move forward a bit better and was heading directly for the dealership but since the power just was not getting to the wheels (transmission?) I pulled over and shut off the truck for a few minutes. Upon starting the truck again, it seemed to move forward better after that but had the 'check engine light' illuminated. The truck is at the dealership now, they have had it nearly a week and said they will not begin to look at it for another week at least since they only have 2 technicians who can look at it.

The infotainment screen brightness is set too high, such that turning the brightness setting down enough for the infotainment screen to not be too bright turns the backlighting on the instrument cluster down to where it's almost unreadable. In this specific case I was trying to use Apple Maps through Carplay for navigation in an unfamiliar rural area, where lighting on the roads is almost inexistent besides in towns. During the day it's not too much of an issue, but any time between dusk and dawn one must make a choice between visibility out the windshield and being able to quickly read anything on the instrument cluster. It is my opinion that this issue is enough of a safety hazard to force GM to make changes, but unfortunately isn't the most egregious "feature" of this screen. That title belongs to what happens when you put the vehicle in reverse at night. It seems whoever designed it thought the view of the backup camera on the infotainment screen is the only thing you should be able to see, since it changes the brightness back to its daytime setting. This makes seeing out of the vehicle in any direction where the screen is even slightly in your view almost impossible. It also means you must wait a second or two for your eyes to adjust if you want to, for example, look at the backup camera on the screen then look out the rear window. In my case, even looking out the rear window into a garage with a light on was difficult after looking at the backup camera view. Add to all of this any kind of vision issues like needing prescription glasses or contacts, and your eyes are constantly trying to adjust between being able to see what your next turn might be and being able to read any signage that may be present. Simply put, it seems GM took the idea of making the vehicle a rolling smart device to be the primary use, even above having the ability to see where you're going safely.

I hit a tree and air bags did not deploy nor did the seat belt lock. Broken 8 ribs, broke my nose, cut my face and had a collapsed lung.

My 2020 Trail Boss recently had a break fail on the front right. The brakes are metal to metal and the brake sensor is reading 54% brake life left. GM says that there is only one brake sensor on the front of the truck and its on the right hand side. When I spoke to Chevy customer service I was told they have received several calls regarding this matter. Chevy service department is saying there is nothing wrong with any of the equipment, but I find it hard to believe that brakes wear this way normally. If they did I would think Chevy would have 2 brake sensors for each wheel.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving and attempting to accelerate, the vehicle shutoff without warning. The vehicle was taken to the local dealer where it was diagnosed that the computer module was faulty. The vehicle was repaired. Additionally, while driving, the brake pedal was depressed however, the vehicle failed to respond. The vehicle revved and there were several unknown warning lights illuminated. The vehicle was towed to the same local dealer however, the mechanic was unable to duplicate the failure after performing a test drive. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure but no assistance was provided. The failure mileage was approximately 16,000.

I was going shopping and noticed my check engine light flashing, it flashed around 20 times then turned off. When I got done shopping, I started up my truck to leave and I had no power steering and the dash had Service ESC on it and the traction control light was on, So I slowly started to drive home with no power steering I drove around one mile and stopped for a coffee. When I jumped back in the truck the power steering was working and all lights and messages were off Being Sunday (12-5-21) no dealer was open, the truck has around 34,000 miles on it This is not the first time the check engine light came on and the dealer checked the codes and it was clear I checked with my code reader and no codes either

I started my truck up and the dashboard warned me with service ESC and also Service Power Steering drive with care. Steering wheel was very hard to turn obviously no matter what way. I only got like 14,169 miles on the truck. I left it sitting for about 2 hrs. And it's supposedly back to normal. No lights some how.

I purchased this truck new and it's now been back 8 times for a engine hesitation, misfire, and check-engine light. On this 8th visit, they replaced the "right bank" of lifters on this 5.3L V8. Previous visits have replaced fuel injectors, spark plugs, spark plug wires, and flashed the ECM. I'm not sure why GM didn't replace the left bank of lifters if it's a known bad part (or replaced the engine entirely). Now I'm just waiting for the problem to come back for a 9th time for yet another part to replaced on an obviously poor engine design.

Vehicle has approximately 15789 miles. Loud taking sound coming from engine began November 2, 2021 as I was on Highway. Dealer advises all 8 lifters and cam need replacement. My investigation reveals that this is a persistent problem with this type of vehicle and many reports have been made about this same issue throughout the USA. My service advisor advised me that they have already repaired several of the same vehicles for the same problem. Engine is defective and requesting a recall to release entire engine now that this engine will need major overhaul.

High Pressure fuel pump failed external fuel leaking onto exhaust of truck. Lucky the truck didn't catch on fire. Would have if I kept driving. What component or system failed or malfunctioned, and is it available for inspection upon request? High Pressure fuel pump (external leak) under GM warranty they have the parts. Flannery Chevrolet Bad Axe MI How was your safety or the safety of others put at risk? Gas leaking on Hot catalytic converter and cross over pipe. Skid plate was full of fuel. A fire under the truck would have made it very difficult to get out of the vehicle once stopped. Has the problem been reproduced or confirmed by a dealer or independent service center? Towed vehicle to dealership and they diagnosed High Pressure fuel pump leaking. they replaced the pump and appears to he resolved now. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not that I know of. GM warranty covered repairs. Vehicle only has 13, 720 miles on it. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Driving down the road started to notice a really bad fuel smell and after stopped you could hear the fuel hissing as it dripped on exhaust pipe. Vehicle sat for 10 mins and had puddle of gas under the front of the transmission. Start the engine again and it continued to drip. I Called towing to come get it.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while stopped in her driveway, the vehicle started rolling forward. The brake pedal was depressed aggressively several times however, the brakes failed to respond. After several attempts, the vehicle came to a stop. The vehicle was taken to the dealer where the mechanic stated that the failure could not be duplicated. The manufacturer was notified of the failure however, there was no response. The failure mileage was 14,562.

Whine sound possible torque converter does not go away. Surging or delay in switching into second gear upon first start up and put in drive.

While towing at a GCWR of over 29,000 pounds, my truck displayed the “check trailer wiring“ message on the DIC. I’m glad that my vehicle alerted me to a situation with the trailer wiring, however, when this message is displayed it completely shuts off the brake output to the trailer brakes. It was incredibly nerve-racking and quite dangerous when traveling 70 mph down the freeway and then suddenly hitting traffic and realizing I had zero trailer brakes to assist me in stopping to avoid an accident. Once I was able to return home, I pulled the breakaway pin on the trailer and all brakes worked perfectly fine. I then pulled all the hubs on the trailer axles and found one brake magnet had wore down to the coil. Obviously this is an issue and needs to be replaced, but the fact that my truck cut break output to all the brakes completely is very dangerous and unacceptable. This is a serious safety issue since there is nothing that can be done while on the road to fix this. If I had been traveling in the mountains as I will be next week, this could easily have caused a much more serious situation. This situation has been discussed among other owners of the same vehicle who experienced the same situation. There is a message that comes up on the DIC, but at that point it’s too late since the trailer brakes are already turned off by the vehicle. It seems to me that unless there is a serious short or the truck senses and extremely high amperage overload that it should continue work and send brake power to a trailer even if there is one single component that fails. That is the way that brake controllers have worked since they were invented, and now this new “Integrated Trailer Brake Controller” is much less safe.

At 11,000 miles my car began to wobble dangerously. I took it to the dealership and they informed me that two Pins were missing from the alignment cams. They blamed Goodyear for not doing a good alignment at 3,000 miles. Goodyear says they see a lot of these issues in their shop and believes GM needs to recall and fix this issue on all of its models. The repair cost me $459.69. GM said this was not covered under warranty, since someone else did the alignment. This doesn't see fair and I think the government needs to look into this.

While driving home in my neighbor I was approaching vehicle ahead of me which was stopped. I applied the break pedal which went loosely all the way to ground and unresponsive. Due to my inability to stop on time I rear ended the vehicle. No warning that there was an issue with my breaks what so ever. The only thing that I did have going on was my trucks front panel (gauges & stereo screen) weren't functioning. I went to turn on my pick up and it behaved as if battery was dead. I let it sit for a few minutes and attempted to start it once again and it started right up. The issue was the stereo screen stayed black and only the fuel gauge and speedometer were functioning. In the end I ended up being at fault in the accident and reported it to my insurance.

The contact's husband owns a 2020 Chevrolet Silverado 1500. The contact stated that while her husband was driving at approximately 65 MPH, the vehicle suddenly decelerated to 40 MPH. The contact stated that the failure recurred on various occasions and that an unknown warning light was illuminated. The vehicle was taken to a local dealer, where the failure could not be duplicated. The failure reoccurred and the vehicle was taken back to the dealer, where it was diagnosed that two brake calipers needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer, where it was diagnosed that the brake master cylinder needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was then taken to Classic Chevy Sugar Land (Southwest Fwy, Sugar Land, TX 77478), where it was diagnosed that the brake master cylinder needed to be replaced again. The VIN was not included in NHTSA Campaign Number: 20V116000 (Service Brakes, Hydraulic). The vehicle remained at the dealer awaiting the repair. The manufacturer was made aware of the failure and the contact was advised to file a complaint with the NHTSA Hotline. The failure mileage was unknown.

275/60r20 Rear Passenger side exploded, damaging my rim. Less than 20k miles on truck.

Esc light comes on brake systems failure max speed 62 mph and tralier brake systems. Abs light , engine light, traction light all come on

- My back up camera developed a fish eye distortion. - It makes it hard to see how close something is behind you, making it dangerous backing up with children in the area. - Yes, although the dealer is trying to claim it is ''normal'', even though it was not that way when I bought the truck, or I would not have purchased it. - There were no warning lamps or other symptoms prior to the problem. It appeared before 2,500 miles were on my vehicle.

Momentary loss of electrical power going over bumps, stabilitrak warning then complete loss of cabin power, engine power and power steering. Corrects after approx 1 sec.

While driving all warnings lights came on and all gage needles started moving back and forth.

Popping sound and hard shifting during low RPM between low gears.

After a morning’s fishing, I drove the boat to the launch site to retrieve and load onto the trailer. Started my 2020 1500 Silverado in the parking lot and went about 75 feet to the launch and retrieved the boat. While I was retrieving the boat, I left the Silverado motor running. After boat pickup, drove about 75 feet in the lot to rig the boat for travel and shut off the Silverado engine. After rigging was completed, started the truck and there was no power steering. The following two messages were present on the DIC: “service power steering drive with care” and “service ESC”. I can’t believe that this truck with less than 2800 miles was exhibiting such a major problem. Restarting the tuck multiple times did not clear the error messages. Since I live about three miles from the lake, I decided to take a chance and drove home and left the truck in the street. Called the dealer and made a service appointment. After about an hour, I went out and started the truck in an attempt to park it in the driveway. The messages had disappeared and power steering was functional. Also, I did some searching on the internet and found many other owners of 2020 1500 Silverado that had the exact same loss of power steering and messages that I had experienced. The dealer informed me that although there were many communication error codes present, they were not able to find the cause of the problem. They requested that I leave the truck with them and they will try to reproduce the power steering failure. The dealer didn’t seem to care, even after I mentioned that there were many others with identical problems and surely someone in Chevrolet engineering knows of the problem and how to fix it. Their response was that they were not aware of any known documented problems like mine. I think I’m getting the run around. They still have the truck after twelve days and no solution. My wife refuses to drive the 2020 1500 Silverado with such an unsafe condition.

I was driving on a wet Road with more than an inch of water on the road and all of a sudden my engine blew up I took it to the Chevrolet dealer and they told me that water got in the engine and it was my fault I feel that the engine failed and should not have

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the check engine warning light and brake warning light had illuminated, and the message “Engine Powering down Mode” was activated causing the vehicle to shut off. The vehicle was towed to the local dealer who was unable to determine the cause of the failure. The contact stated that the failure had occurred on several occasions and the throttle body, Oxygen sensors were replaced along with an engine programming update was performed but the failure continued to occur. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 77,154.

Rear window leaking like a small stream in regular rain. It’s going down behind seats and carpeting and headliner staining worse and worse and I am worried about black mold being created. Husband has lung issues and that can be verified by our physician. We have told Jenkins chevy in Venice florida 5/4/22, 3/20/23 and now living in TN spoke to Champion Chevy in Johnson City on 9/29/23 and 1/5/24..it’s getting worse and as we are out of warranty no one wants to help. We never received any bulletins on my chevy site and it’s not anything you would normally notice but now we smell the mildew smell back there because it is getting worse. Please help us before we get ill from this awful leak. This is my first Chevy pick up I have purchased in my lifetime. Possibly the last..

Vehicle purchased December 2020 Flashing check engine light that stays on- light did not stay on long enough for dealer to see, said they couldn't find any issues. The first time we had it towed and when they looked at it the light was no longer on. They were able to tell us what was going on with the vehicle when the light came on but said there were no problems. Flashing check engine light that turns off- "no light = no problem" dealer says. Eventually they printed pages showing engine misfires which we were initially told was no big deal. Later I was told I should get spark plugs changed, which I did. So far, flashing light has not reoccurred. Burns 3 or more quarts of oil between oil changes which I was assured by more than one rep that that was normal (on numerous occasions). Air conditioning quit working. Heater not working well and not at all on idle. The only setting I can really use to defrost and keep my feet warm is the "floor only" option. Mixed doesn't work, defrost only will freeze feet. Gas smell while vehicle at idle. Initially noticed when using auto start but have since noticed it does it with regular start as well. All issues have been brought to dealership, I will have to contact them for all the exact dates.

At least 3 times while driving the entire radio and information system has shut down while driving and completely gone black for 2-3 minutes and reset to factory reset This does not show as recall but worried that it may shut down vehicle completely Have told dealership during routine maintenance and they said they find no problem Obviously there is a reason this is happening

Driving 50mph and the truck starts bucking, backfiring, and missing. Code appeared on the dash stating service ESC. Lack of Power steering and braking I parked the truck.

Service ESC and Service Parking Brake error. This was followed by loud pinging noises from the engine. Sounds like a misfire and knocking heads or valves.

Service ESC and Parking Brake error. Drove to work with no issues. Started up to drive home and I kept hearing a "Ping" noise like hail hitting my roof. Then I thought my transmission was going out while driving. It is almost like it is firing out of order. Dealership ordered multiple parts: Misfire in cylinder 4 plus issue with the heads and push rod. GM decided that the issue it to be repaired rather than a new engine be put in.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving approximately 40 MPH, the vehicle suddenly started to shake and misfire. The contact stated that the ESC warning and service parking brake warning lights were illuminated. The contact coasted to the side of the road and restarted the vehicle. The contact took the vehicle to the dealer who diagnosed that the electronic stability control module had performed an automatic reset as designed. After the reset, the misfire occurred. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 7,700.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 10 mph, the vehicle drove through a puddle of water, shuddered and jerked then loss motive power. The contact was not able to restart the vehicle. The contact had the vehicle towed to a local dealer who inspected the vehicle and diagnosed the failure as water entering the engine, and that the engine needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 21,400.

I was leaving work on May 17th and got in my 2020 Silverado and started the vehicle. Immediately codes were thrown on the dash stating that the power steering was out and that the ESC system needed serviced. The traction control system/ESC light was also illuminated on the dash. I was unable to turn the steering wheel whatsoever. I turned the vehicle off and restarted approximately three times all of which still were displaying the codes listed above. I let the truck sit for approximately 20 minutes and the codes had cleared themselves and the vehicle was functioning as it should. I immediately drove to the dealership and had it serviced. Dealership stated there was a programming issue related to the EBCM, which if I'm not mistaken was a recall already issued for the 2019 models. I have seen many instances online of this same issue occurring and sometimes impacting the ability to brake (if vehicle was in motion at time of onset). My onset occurred at approximately 14,000 miles while in park. Since the servicing (approximately 1 week) issue has not been replicated, but I am not sure if the problem has been fixed or if the computer is just functioning properly and will glitch again at some point in the future.
