2020 Chevrolet Silverado Complaint Log

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 50 MPH and making a turn in the opposite direction, the vehicle lost motive power and there was an abnormal knocking sound coming from the engine. There was no warning light illuminated. The contact was able to pull over to the side of the road. The vehicle failed to restart and was towed to the dealer, where it was diagnosed and determined that the rod and the lifters had failed, causing damages to the upper half of the engine. The dealer replaced the gaskets, the rods, the guides, the lifters, the camshaft, and the transition kit. Additionally, and oil change was performed. The vehicle was not covered under warranty and was repaired at the customer's expense due to the mileage. The contact stated that while driving approximately 65 MPH on another occasion, the vehicle made an abnormally loud clunking sound and lost motive power intermittently. There was no warning light illuminated. The contact pulled over to the side of the road. The contact drove back to the residence. The vehicle was taken back to the dealer, where it was diagnosed with cylinder #8 intake valve failure. The vehicle was repaired at the contact's expense. The manufacturer was notified of the failure and a case was filed for the cylinder #8 intake valve spring replacement. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 86,000.

On January 17, 2025, I was approaching the entrance ramp unto Interstate 10, traveling along at approximately 40 miles an hour, when all of a sudden I noticed that my vehicle started decelerating as I was pressing on the accelerator, trying to merge onto oncoming traffic. The engine started shuttering and vibrating violently! I noticed all the warning lights, gauges and indicators had come on simultaneously! There was a loud clicking sound coming from the engine compartment and backfiring coming from the exhaust. I evaluate the situation at hand and conduct a risk assessment of trying to continue on with this problem but decided to move over to the median. I was almost run into from the rear due to lack of power in which I felt would have been the result of my truck just losing power without any warning. I drove my truck to a Chevrolet dealership after speaking with a Service Advisor, on January 20, 2025. The Truck was diagnosed as needing to replace Cam Rod and Lifters.

Upon entering a roadway from a parking lot I noticed my vehicle struggling to gain speed. I lifted my foot from the gas pedal and the truck rapidly reduced speed, dropping from 25 mph to less than 5mph in a couple of seconds. I then reapplied the gas pedal to attemp to avoid the vehicle approaching from the rear. The truck struggled again to gain speed. I went about 150 yards toward an intersection. I applied the brake and pushed it to the floor as the truck barely slowed to a stop. Had there been any vehicle stopped in front of me I would have hit it and pushed it into the intersection. The dashboard lit up with warning lights and rotating messages such as, Brake system failure 62 mph top speed, Service trailer break.when the traffic light turned green I drove it across the intersection into a parking lot, going about 5 mph for 50 yards. Putting my foot back on the brake as hard as I could. It finally came to a stop about twenty feet farther than it should have. I had it towed to a Chevrolet dealership. They did a diagnostic test and checked all braking components. They found a service bulletin for recalibration of brake system control module. They preformed the calibration and cleared the codes. After reading the many reports of this happening on the NHTSA site and the absolute possibility of injuries and deaths, I find it hard to believe that with knowing this problem exists and it’s disastrous potential, that there has not been a recall after 5 years of complaints.

From the time my vehicle had 30,000 miles on the engine, the engine light would come on and stay on with no apparent reason. I would take my car to my local Chevrolet dealer each time (by this time the light had gone out) and they could not find a problem. One technician told me that it sounded like a lifter problem that they were experiencing with these model vehicles. This happened approximately 8 to 10 times before the lifter failed. In January 2025, while driving on the Interstate Highway I experienced a sudden engine vibration and immediate 50% loss of power. Upon returning home, I took my truck to my local Chevrolet dealer where I purchased my vehicle. Upon inspection, I was told that it was apparent that a hydraulic lifter had failed. I left my vehicle at the dealership for the repair of the failed lifter which cost me $4,800. Two months later, I experienced the same problem with the engine, more violently vibrating. I again took my vehicle to the dealership and they confirmed another lifter had failed and took it in for repair under warranty from the prior lifter repair. I had again experienced more than 50% engine loss and had to get off of the interstate and travel on a side road because I could not maintain a speed over 45 to 50 mph. They repaired the same failed lifter bank that they had repaired the first time. Now, I am holding my breath, just waiting for the lifters on the other bank to fail for me to have to put in another $4,800-$5,000. I believe that this is an engine flaw that Chevrolet knows about. They have done nothing to fix this issue and have left it on the backs of the customer. Chevrolet needs to be accountable for these types of problems!

Vehicle started miss firing along the highway without any previous signs of problems. The vehicle was driven straight to our home and then to the dealership a few days later. We were told there, the lifters have failed. Once they started the repairs we were also adviced the cam have suffered significant damaged and needed replacement as well. The vehicle was only inspected at the dealership once it was dropped off. The first and only sympton of the insurance was the day it failed.

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.

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.

Driving vehicle down freeway about 75mph heard noise and truck shut speeds down to about 60mph on a major freeway. Per mechanic lifter has collapsed and it has been a common issue that Chevy knows about. He said that it could have been alot worse by seizing the engine and causing harm to drive or other people around causing a major accident. There is a major safety issue to life and or death caused by this issue that has NOT been a concern and causing people to pay over $5000.00 for repairs. Chevy has known about the faulty lifters for years and doesn't seem to care about safety concerns.

While driving my transmission has a shutter. The shutter started about yr and half ago and I have just maintained with shutter stop. I know there is a recall on manufactured parts for other Chevrolet trucks in the same yr

Engine shut off while driving home from work on15 October 2024. Driving home while raining. Engine just stop and wouldn't start again.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 65 MPH, the front wheels seized, and the contact was forced to pull over to the side of the road to restart the vehicle. This failure reoccurred a second time and while pulling over the front wheels seized, and the brake pad and rotors were visibly red. No warning lights were illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Check engine light came on at 100,000 and was told I need new engine from John Miles Chevrolet

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.

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

I bought this truck with 72,000 miles on it I put about 3,000 miles on it and the engine seized. I had my mechanic inspect it and he confirmed the motor is seized. There was absolutely no warning is just stopped running and left me on the side of the road

While driving my truck the engine completely shut down. All the dash lights came on initially but then only the check engine light stayed on. My truck never would start back up after that. It was towed to GM dealership who diagnosed catastrophic engine failure.

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

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.

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. 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.

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.

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.

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 vehicle was being used in a normal daily driving routine. I was stopped(fortunately) at a traffic light. The light turned green and I went to proceed and began to press the gas pedal and the engine made a loud pop noise and began to barely stay running. I brought the vehicle to the shop(GM dealership) for diagnosis and repair. The motor had to be rebuilt new camshaft, lifters, etc. The vehicle is also having transmission issues, heavy vibration, hard shifts and constant fluctuations in the rpms while maintaining a set speed. The transmission issue still has not been resolved.

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.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that after starting the vehicle, the engine made ticking and knocking sounds while idling. No warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the year and VIN were not included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 59,000.

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.

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

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.

Wiring harness defect an on going defect required repair in General Motors products should be a recall. Dealership said a manufacturing error. Now public who buys these vehicles have to pay for General Motors defect. Cylinder cause check engine light to come on. Repairs by Kunes GMC of Beloit WI. invoice [XXX].

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

Transmission is sputtering when trying to shift. Mostly at low speeds it's extremely jerky like it doesn't want to go. Had Transmission fluid and filter changed, but it did not help.

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.

significant loss of power due to engine failure related to DDI while driving.

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.

transmission make noise

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.

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.

Transmission continues to lock up while driving

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.

The manufacturer was not made aware of the failure. The failure mileage was approximately 53,000.

Key will not fully turn back and release, keeping the accessories running. After many start, shift, move a little and waiting for a period of time it eventually turns to normal to remove. I’ve seen articles on if it says “shift to park” on the dash lights and it does not. Bought used with 70,000 10/24 and continues to get worse.

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).

Transmission shuttering when driving

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, there was a ticking sound coming from the engine compartment. The contact stated that the sound later became an engine knock, and the vehicle stalled. The vehicle was towed to the local dealer, who diagnosed the vehicle and determined that the engine had failed and needed to be replaced. The vehicle was not repaired and was later towed back to the residence. The manufacturer was not yet contacted. The failure mileage was 75,718.

Before teuck engine collapse. Ww had concerns about truck sounded off. Misfire in engine, knocking noise. Truck shut down. Had it towed. GMC service department concluded that the 5th cylinder not firing properly. Lifters collapse. Fixed, it was costly $10, 100. Truck went back in shop next day mexhanic was busy. Waiting til after weekend to take truck back in. They had to physicallt look at why truck was vibrating. Engine light not showing issue. Neither did the code reader. Mechanic found provle to be the Torque convertor. Need to change that. Said it was a very common problem in Chevy trucks.

With only 70,000 miles on the truck it started to have a hard shudder and wheels locking up. During the wheel shudder it would shift hard as well. We took it to a shop and they said it was our Transmission control module and that the transmission had metal shavings and would fail soon. They also said doing any service to these transmissions can cause failure.We were informed that the dealership is aware these transmissions are all failing. The cost to replace is over $6,500. The dealership should have to do an official recall for this. After some research i found that the dealership has acknowledged the issue by replacing the TCM and uploading new software to put the transmission into a fail safe instead of putting in a new transmission. The issues that the failure causes has made thousands of people have to get new transmissions before the service is even due. A quick search on Google states that 461,000 vehicles were effected and that a recall has been issued, but it has not been officially issued. We need a new transmission and should not have to pay for it on a truck that is so new and serviced timely.

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
