2020 Chevrolet Silverado 1500 complaints

While driving home truck began to misfire and drop in RPM’s. Service ESC and Service Parking Brake popped up on my notification system. My Engine light was blinking and my Traction light was on. While i was turning into my street to get home, my engine shut off. The steering wheel and brakes became hard as the motor wasn't powering them. I was able to turn it on and get it into my drive way. Afterwards when trying to turn it on, it would turn on and shut off immediately. Chevy replaces a fuel pump module for a second time(recall), added a new starter and battery. After Three months they then told me I need a new engine because it has locked itself up. I purchased the vehicle with 32,000 miles and It currently has 49,000 miles. Chevrolet are not going to warranty me a new engine because i do my own oil changes (which were 2). Had this happened on the highway or in traffic, i would've been at a high risk of causing an accident considering power steering and brake system was not working properly.

Truck has been burning oil since it was purchased new in 2020. The truck has needed 6 quarts added between every oil change. It has been to the dealer and they insist nothing is wrong. GM customer service has been no help. Motor has a ticking noise. Finally 2 weeks ago check engine lights came on and loud noises came from motor. Brought it into the dealership and they said full lifter failure and engine scoring and has been like this for awhile now. This is something I brought up to them AND GM support over the last 4 years of owning the vehicle and they always told me there was nothing wrong with it. Private extended warranty is going to cover a new engine, but is on national backorder due to all the issues with the 6.2L engine and others having issues GM won’t acknowledge.

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.

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

Upper control arm ball joint separated.

Excessive Oil consumption from new and lifter failure at 116,000 miles

Had the top of the motor rebuilt twice, first the left side, then the right side. Then GM replaced the motor out of warranty. A year and a half later the rear main seal blew and the seal was all mushroomed and out of shape.

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.

Purchased not thinking there would be issues as truck was clean and well kept. Month and a half later torque converter went bad. Had it replaced under warranty, however, I have more symptoms from when it originally started. 6 speed transmission.

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.

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

Transmission shuttering when driving

Rear window leaks water into the cab during rain, snow, car wash, etc. GM refuses to abide by comprehensive warranty to fix the issue, and my dealership wants to charge around $1,000 just to apply sealant. Water goes into and behind the rear seat (where my child sits) and goes to unknown area. Water can cause rust, mold, electrical problems, or any other number of issues. I noticed it around November of 2024 but I don’t know how long it has actually been occurring for. When researching this issue, appears to be relatively commonplace for my year and style of vehicle. Even the GM techs at my dealership acknowledged it is a recurring issue that may require MULTIPLE visits before getting a permanent solution (replacing the entire window).

While driving down the highway, the ball joints on the front passenger side prematurely failed, causing loss of vehicle control, significant damage to steering and braking components and body damage. Diagnosis is being confirmed by an independent service center. No symptoms of premature wear or imminent failure were noted.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at various speeds in inclement weather including while driving in rain or slushy snow, the tailgate inadvertently opened. The vehicle was taken to a dealer where it was diagnosed and determined that the tailgate switch needed to be replaced due to water intrusion. The manufacturer was notified of the failure. The failure mileage was approximately 14,000.

The rear wheels lock and most of the time its hard shifting/ or it feels like it struggling to shift to the next gear

First incident was when the vehicle had under 7,000 miles. Transmission module went. Vehicle wouldn't move. A few months prior, when we pulled our camping trailer, the integrated brake didn't work and the truck brakes overheated. Took vehicle to dealer, couldn't find a problem. A few months later the truck would not move, and found to be the transmission module. After a month and they finally got the part and repaired, no problems with pulling the camper. Than last week, we pulled out on the road, and we couldn't accelerate. A little over 45,000 miles on it. Had towed to dealer, they have diagnosed Transmission Valve Body. No warning lights. Maybe the transmission was hesitating some before it went. Waiting for the part, which no clue how long it will take.

2020 Chevy Silverado 1500 8L90 transmission failure at 40,000 miles and I am now at 90,000 miles with the same issue. I have been working on this truck tirelessly tried to fix the transmission. I’ve had 3 transmission fluid replacements and a full torque converter replacement. General Motors knowingly sold these models to consumers when the transmission was faulty and underperforming. It shudders, shakes, and slips while driving. It’s almost caused me to get into a few accidents. I just want compensation and to be a part of the class action lawsuit they are being filed upon.

About a month ago, began with a shutter or studder at low speeds. Became worse and a vibration on the interstate as it sounded like i was driving over rough ground. have now seen two mechanics in person and talked to another on the phone and all are saying the torque converter needs to be replaced. the check engine light has not come on which is also a concern as this is a major issue. safety concern is getting on the interstate into traffic and difficulty accelerating. experienced a lockup and swerve when accelerating up a hill which is very scary as my children were in the car. this is a 2020 silverado 1500 purchased new from dealership with 105k miles

Wiring harness defect an on going defect required repair in General Motors products should be a recall. Dealership said a manufacturing error.

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.

Driving at the speed limit 65-70 miles ph my truck started to slow in speed the tire sensor came on then the truck began to smoke and the brakes locked up at a high speed, lucky for me there was no one behind me. I was able to limp to a safe spot and park the truck would not MOVE at all..After an hour I tried to move it again it would not go into drive. Had to tow it to the dealership..$$$$ later they say well we can't recreate the problem so it's drivable. I drive 2 blocks and it stops in traffic almost causing a collision. Had it towed home and for 3 moths now it has sat while I have to continue paying payments on a NON running 2020 with only 102 thousand miles on it this is CRIMINAL!!!!!!!!!!!!!!!!!!!!! was told possible $62k to repair but no guarantee it would stay fixed!!!!!!!!!! Criminal and should not be on me I am paying still. But if something is not done I will let it get repo..I am [XXX] old this was to be my last newer vehicle I have had to borrow money again and bought an older 03 silverado that is running great.

Main bearing on crankshaft when out

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

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while the vehicle was parked, the brake pad sensor warning light illuminated. The vehicle was taken to a dealer to be diagnosed; however, the vehicle was not yet diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 32,000.

The contact owns a 2020 Chevrolet Silverado. The contact stated that while driving at an undisclosed speed, he heard an abnormal sound emanating from the rear end suspension. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that fuel leak from the fuel delivery system resulted corrosion of the left side leaf spring grummet. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 30,000.

The specific issue that is being recalled is malfunctioning on my vehicle. I have taken to the dealership but they won’t help because the solution hasn’t been identified. My truck has suffered repeated failures resulting in excessive wear and tear on the transmission. I’m afraid a catastrophic failure will occur if I have to keep driving, without a solution. The dealer simply cleared the code. They should replace the part that is failing at a minimum. Even if it might happen again down the road. They will have a solution by then.

Dealership attempting to sell a vehicle with an open recall was more than prepared to let me drive and potentially sell a vehicle with a recall open causing the rear tires to randomly lock up. Made problem known to salesman and said they'd take it off the market. Now, they lowered the price by $2600 as it was previously listed at $25,571, now listed at $22,971. Listing still not down.

This vehicle, only 4 years old, experienced lifter/engine failure during normal operation, which required unsafe driving conditions and a roadside emergency. The vehicle was towed to the service location, where a complete engine disassembly took place, and required a 3 week repair period. The truck experienced a rough idle/shudder at a stoplight, then proceeded to show a flashing check engine light (P0305), a service emergency brake warning, and a service traction control warning.

While driving, the vehicle began experiencing hard shifting. When I attempted to accelerate to pull over, the vehicle failed to respond and instead sounded as though it was in neutral. Additionally, when I tried to bring the vehicle to a stop, it took longer than usual, as if the wheels were locked.

Brake system lights on dash came on as well as the check engine light. Park light was flashing on the dash. Safety is at risk as parking brake does not work. Took vehicle to dealer and they ran diagnostics. Codes: c0610 05, c0616 5a as per document id: 5709204. They said I need a new Brake System Control Module. Brake System Control Modules are on backorder. Brake System Control Modules have been recalled on Silverados in the past. I'm worried that this is unsafe

My vehicle only has 20k miles on it and I’m already replacing a lifter and camshaft due to the active fuel management system. At the time of taking my truck in there are three other trucks for the same issue. This is known issue at my dealership and this time I’m covered under warranty, but they told me to be prepared to repair this again and next time will be out of warranty and around 5k to repair.

Engine light came on, service park brake light came on, truck started jumping and misfiring, code says cylinder 5 misfire.

Brake failure. I took the Truck to the dealer and was told not to drive it. The dealer ran two checks and then said brake failure. The rep had to leave, so another rep put my car in the shop overnight. The next day, I was told in writing that they could not find any problem. The code clearly showed brake failure. Date: [XXX]. Cost: $125.69. Mileage was 53,531. On [XXX], another brake failure. I went to an auto parts dealer (O Riley) in Topeka, KS, and they found a brake failure code(I have a copy). They told me to go to the dealer. I went to the dealer with a stiff pedal, which means driving is very unsafe. The dealer said too busy with oil changes and told me to return another day. I said no breaks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2020 Chevy truck falls under the recall out right now. I drive my family around in it and feel a bit unsafe. How long does General motors have a remedy for this recall? And what are the next steps if a remedy isn’t made in the timeframe allowed? I’ve contacted General Motors and cannot get an answer. Thanks

The truck is only three years old with 123,000 miles and the transmission needs to be replaced. I took the truck to Chevy and they said the transmission is bad and they need to replace it. GM and Chevy will NOT cover the cost to replace the transmission or help with any cost. This truck is fairly new and it's a lot that the transmission is already bad. Chevy quoted me $7,990 for new transmission with install.

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 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.

The manufacturer was not made aware of the failure. The approximate failure mileage was 97,000.

Transmission continues to lock up while driving

I have already sent in one complaint about my vehicle and a recall came out but my vehicle isn't on the list and I know there is something wrong. My steering wheel will lock while driving my transmission sticks sometimes I can steering because my steering wheel acts as if it does not work. I have had horrible vibration since day one I have to get an alignment 2 to 3 times a year

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.

Rear sliding plastic window frame cracks and allows water to seep into the cab. Hardware and metal brackets have rusted, electrical components may be at risk of shorting out. Mold and mildew can be smelled on warm days, which poses a health risk. Complete window has been replaced twice and original and replacements have all been resealed as a "repair" but has failed on all attempts. Headliner has been replaced once and is currently stained again due to another leak. No updated GM part exists to remedy the known issues.

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 investi

My truck has 75K miles and the transmission has a shudder and it shifts very hard. I have been told I need a new transmission by an AAMCO shop which will cost just under $7k. This is ridiculous for a 2020 pickup.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed and driving over a speed bump, the contact noticed that the power steering became inoperable with the Electronic Stability control warning light illuminated and the message that the “Power Steering was Disabled” was displayed.

Vehicle has approximately 45k miles, We were 2.5 hours away from home on a paved highway driving 55mph and the front passenger side ball joint failed and upper control arm separated also Instantly no brakes causing an accident . This is very dangerous and is going to kill people , we are lucky we didn't roll . I'm now afraid this will happen to the other side? chevy will not take the responsibility to fix it , our extended warranty only covered the upper control arm and not any of the other parts that had damage due to the ball joint . it was a 2.5 hour tow as well . Also the tow truck driver said within a week this was the 4th Chevy truck with the same issue 2 of them Rolled . Side note , As I looked into this I haver found other of this same model vehicle to have the same problem , one that it happened at around 40k miles he fixed it then it happened again on the other side at around 50k miles on the same vehicle . There needs to be a recall , Chevy has other models that have had this recall but no recall for my vehicle? links to related proof there is a big problem [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
