2020 Chevrolet Silverado Complaint Log

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

the transmission on my truck shudders and shakes very badly, contacted GM ,also the dealer told it would take 3-4 weeks to repair , i am left without away to work.

My car turned left with the risk of jumping to the opposite lane. It happened twice. First at 40 mph and the second time at 70 mph. I didn’t feel any issue with the steering drive but more with the traction. I’m not sure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at 30 MPH, the vehicle briefly vibrated and shuddered before losing motive power. After tapping the brake pedal and rapidly accelerating, the vehicle continued to vibrate and shudder but eventually returned to normal functionality. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 78,000.

About a month ago I noticed some intense shaking in my 2020 Silverado 1500 RST when braking. The shaking is not only felt in the seat and steering wheel, but is also observable in the dash and in the gear shifter. Due to the obvious concern, I made an appointment with the dealer who, after inspection, stated that all 4 rotors were warped due to overheating. I mostly use the truck on the highway, tow a river raft (easily carried by 2 people) on a small trailer 2 times a year (about 70 miles roundtrip), have never used the bed with excess weight, do not ride my brakes when driving, and I live in Alaska where the temperature is cool (high temps rarely exceeding mid 60's). The brake status report on my dash presently shows my original brake pad life to be 83% on the front and 89% on the rear which was inline with the dealer report that the brake pads were still quite thick. These prove that the brakes have not been overused or abused. According to Kaufman and Associates website, "General Motors is recalling over 350,000 2020 Chevrolet Silverado and GM Sierra pick-up trucks due to a fault in the brake system....The issue involved a lack of heat-treatment for the bolts used to attach both the front and rear calipers.....The issue comes down to long-term performance and safety....Untreated bolts run the risk of breaking under loads, and this can result in braking issues, wheel rotation problems, and internal damage to other parts of the truck. These trucks also suffered from brake system control module and premature brake wear issues, and countless owners have reported brake system issues as varied as check engine lights to outright brake failure." According to the local dealer, my VIN isn't included in the recall and they cannot fix it until it is included (or I dish out $2k). It seems obvious that the issue in my truck is the same that led to the recall of the other 350,000 trucks and I simply need my VIN added so that it can be fixed before catastrophic brake failure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated when she started the vehicle and attempted to shift into reverse(R) there was an unknown warning light illuminated.

The contact had not taken the vehicle to a local dealer or independent mechanic to be diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was unknown.

The driver airbag has rusted causing a service safety restraint system light.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the emission system warning light and the throttle control warning light were illuminated. Additionally, the contact stated that the vehicle shuddered while being started. The vehicle was taken to the dealer, who replaced the spark plugs and made several other unknown repairs.

Around 35k miles had an engine lifter fail and needed to be replaced, covered under warranty. 07/2023 - Had front pads/rotors replaced by Chevy dealer and had loud squeaking ever since. Contacted dealer and was told they are new pads so will just need time to break in. Contacted the dealer again in Sept.Oct. 2023 and brought vehicle in for service for noise concern. They informed me the noise is coming from the rear brakes that was reported as 60% life two months prior. They replaced the rear rotors/pads and noise persisted. Brought vehicle back to dealer in December, they performed a serviced but was ineffective. In March 24 started getting some vibrations when stopping. Brought vehicle for servicing, stated there are rust spots on rotors but everything is wearing fine so this will not be covered under warranty. Also that they do not warranty sounds due to pads can have more metallics then others and they cannot determine which ones do not. I looked under forums and GM Pads seem to be a common issue with noise. My truck was perfectly fine before these brake products were installed and I would like GM to be held accountable for there inferior products leading to loud break noises and violent vibrations while braking !

while driving i smelled what i thought was strong exhaust from a vehicle in front of us. It was actually gasoline fumes entering the cab from my truck's engine compartment. I pulled over and investigated the smell, we had to let down ALL the windows and turn off the AC. There were no warning lamps. There was, however, gasoline dripping from around the transmission area of the underside. It was dripping on the exhaust which was causing most of the stench. It wasn't a heavy drip but enough for me to skip any other planned errands. When we got to the house gasoline was dropping from six or seven places under the car. The next day we set an appointment for the dealership to look at it. When I drove into the dealer the car was still gushing gasoline and I told them about the recall for the High Pressure Fuel Pump. It turns out that's exactly what it was. However, although my RPO (L82) matched the designated recall, I was told my VIN was not included and I would have to pay...bummer. I don't think the recall cast a big enough web to catch all affected vehicles. I have a video but no photos.

The key will get stuck in the ignition cilinder when I try to turn off the truck. This happens several times, I got to turn it on and off several times to get the key out of the ignition barrel. The truck was taken to the dealer to be repaired, they replaced the cylinder (part #13528553) and the housing (part# 84990323) AMD it didn't fix the problem

I had just left RV Park in Kingman, AZ. I had cruise control set at 59MPH when My truck began a violent shacking and a lot of banging. I pulled over on the shoulder of I-40, Got out to find tread had come off of the tire and was now wedge between brake backing plate and leaf spring. It had not lost air. Just tread came off. When tow truck driver showed up several hours later, tire was still holding air. He jacked up the axle, but deflated tire before he would remove it from truck and put on my spare. I always check my tires when I leave rv parks or after stopping at rest stops. Saw nothing wrong with tire or air pressure that morning. I had only been driving 45 Minutes, outside temp was low 80's.

Rear window seal is leaking causing mold in vehicle.

dash gauge cluster - ALL gauges drop to "zero" while driving speed, oil pressure, engine temp, fuel, etc., a/c compressor stops working but blower still works

While driving down the interstate hi-way, I heard a pop and my truck started to swerve into the adjoining lane. I turned the steering wheel in the opposite direction and the truck started making a rubbing sound and very hard to steer. I finally got it to the side of the hi-way and seen my passenger side front wheel leaning in. The upper balljoint/control arm broke. Luckily no-one was in the lane next to me or it would have caused a serious crash.

2020 Silverado 1500 LTZ, Turn signals on mirror do not work

Electrical acutated tailgate will not come down. The truck came with a soft bed cover that locks. If my child was to hide in the bed somehow it would pose an immediate risk to life and health as the tailgate will not come down and does not have any type of manual override. The interior controls do not work to lower the tailgate, the key fob controls do not work to lower the tailgate.

I am writing to formally report a persistent and dangerous manufacturing defect regarding the rear window and seating assemblies in my 2020 Chevrolet Silverado. I have already had GM replace the rear window in 2023, it needs replaced again now in 2026. The rear window seal is failing, allowing a significant amount of rainwater to leak into the cab. Because of this ongoing water intrusion, the structural base and brackets of the rear seats have developed severe rust. Furthermore, I am deeply concerned that this constant moisture saturation is creating an unseen mold hazard within the cabin, which poses a direct health and respiratory risk to my passengers.This leak also risks damaging sensitive electrical components and wiring harnesses located under the rear seats and trim panels, potentially causing short circuits and sudden failures of critical safety systems while driving.Many other owners of this generation Silverado have reported identical issues, including cracked plastic frames around the sliding rear glass that cause the leaks. Because this defect compromises vehicle integrity, creates a risk of electrical failure, and poses health hazards from mold, I am requesting that the NHTSA investigate this issue as a potential safety defect requiring a manufacturer recall.

Sliding rear window leaking, causing mold and ruined seats. Had it "fixed" in 2023 only 3 years of owing it. Now here 3 years later the same issue is occurring and they're not willing to make it right. Mold causes a safety hazard for my children and anyone in my vehicle. My truck only has 30,000 miles on it and I shouldn't be having this issue

Brake system light failure. Some system lights came on. I had no breaks car didn’t stop fast enough before hitting a pole

On a 3 year old vehicle, I had a dash full of warning lights come on along with the engine light. Upon checking the code for the engine, it shows a misfire on cylinder 5. Looking online, chevy has a tsb # pip5776c regarding lifter failure. It appears this is an ongoing issue with many of the vehicles as verified by an engine repair shop. They stated then engine may need replacement as they have found in the past. For a 3 year old vehicle with more year of payments this is not right. They know of an issue and after speaking with a dealer, they said its on me because I am over the mileage warranty. I do not have the repair done yet--it is not cheap

The truck only has 54106 MI problem with the key coming out after turning it off . Have to turn engine on and off until the key comes off.

My backup camera is not functional and it stopped working in April a month after I purchased the vehicle before my lease expired in May. I took it into the dealership for a software update and they refused to do anything without charging me a $160 fee.

Component? Multiple: lifters from bank 2 which caused multiple other components to be replaced consistent with GM protocols such as bent rods. Safety: The vehicle jerked causing it difficulty to safely operate the vehicle which ultimately left stranded. This was also unsafe for other motorist as it was difficult to operate while trying to safely get to the side of the road. The dealer repaired the vehicle after confirming failures. No one other than the dealer inspected the vehicle to date. Warning lamps only appeared after vehicle violently shook.

Vehicle is at 67,xxx miles. Vehicle is losing power, check engine light, service 4wd, service esc, service power steering, service parking brake..... the gas pedal has locked on me already with my 3 small children in the truck at highway speeds. GM says it's fine. I have all the work orders where 2 different dealerships have "corrected" these issues under warranty. Go retrieve the vehicle and within a week Vehicle is back acting up. This truck is unsafe to drive on the roadway. I have not been offered a courtesy vehicle to drive while "warranty" work is being done. I am appalled and in fear for my children and my own life with this truck.

Rear window seal leaking.

The frame of the truck is excessively rusty and the manufacture undercoating has flaked off. All components of the frame and underbody have significant rust for the age of the vehicle. This was just addressed with the dealership who stated there was no warranty to cover it. There has been no service done to the frame and all preventative maintenance and service checks have been done at the dealership on time. It was just recently noticed to be so rusty. This poses a problem with the safety of the frame of the vehicle which can lead to cracks, broken welds, holes, etc.

Was riding down the road and my front left caliber locked up had break fluid running down from the upper reservoir the truck only has 46,000 miles. the truck was immobile had to have it towed and had to get a new caliber and took the shop almost a week to get air out the system breaks are still not 100 percent also rear breaks are having a problem fully releasing as well. Leaves me worried the rear breaks will seize up as well cost me 1000 dollars for the repairs

VEHICLE WILL SEND MESSAGE TO MESSAGE CENTER TO SHIFT VEHICLE IN TO PARK WHEN IT IS ALREADY IN PARK. HAVE TO TRICK VEHICLE SYSTEM TO MAKE IT BELEIVE IT IS IN PARK TO TOTALLY SHUT DOWN VEHICLE

Power steering failure upon starting truck. Wheel did not turn. Dash message said Esc and power steering malfunction . Restart car multiple times with same issue. Wait a few hours and start car - no warnings or power steering issues. Went to Chevrolet dealership and was told no codes had been triggered and to bring back when issue arises again.

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 .

Transmission will hard shift from 2-3. It jerks the truck and causes power loss when in traffic. The RPM's will go up to 3500-4000 and then the truck barley keeps a speed of 45 mph. The engines sounds like it is going to explode! This has happen several times with 32000 miles on the truck.

Trailer brake controls not working. Safety at risk due to electric trailer brakes not working. Other lights and functions work when trailer plugged in.

The tucks are high so a backup camera is now more important than ever. During the day the image very grainy but useful. At night or in a dark garage it completely useless. I took my truck in to be checked and they agreed it was terrible but nothing could be dome until a recall was issued. I've done research and this seems to be a huge problem with the 2020 Silverado. I reached out to Chevy and the lady I chatted with said I should file this here with you. There are multiple chats and message boards about this issue and Chevy lack of being willing to fix it.

I'm experiencing all the documented issues with the 10L80 10 speed transmission. Identical to all the recalls. It's shifting poorly, torque converter shudder, lose of power, unreliability, and serious safety concerns. I've tried to communicate and find a resolution to these issues through the dealership and GM. Of course getting nowhere. I don't feel a 60k dollar truck should be in this kind of condition. Recently the ac compressor went out. Conveniently after the 6.2 was considered faulty and was replaced but transmission denied. Which the dealership GM expressed in no way was any factors the warranty companies claims of a taller tire being on the truck. Being the issue at all for the transmission failure. Also the dealership didn't check a box. One that I can not physically check. Which they put on me. They swapped the stock tires to the taller brand new set I'd just bought for my trade in. Never stating anything about the tires being taller voiding the warranty I just paid for. Why would I deny the part of the extended warranty that I wanted. Cause of the suspension and drivetrain. Either way this truck is not safe to be on the road. It struggles to maintain speed on the highway. Eventually leading to the torque converter free spinning and making all kinds of noises and vibration. Of course once I've assisted it to violently shift through the gears and hopefully into 10th. On occasions it never makes it that far. Either way I feel this falls directly into the recalls with the same model and year. They replaced the 6.2 cause of cylinder failure and oil consumption. Well the next in line for the drive train is the junk 10 speed. Not sure how it can't be related. The long and stressful time. I've put into finding a solution with the dealer or manufacturer. They blow me off or just don't give me any info. I feel that's their way of dismissing not only the failure of the salesman not properly doing his job. Which the GManager also stated mistakes happen. Not OK
