2020 CHEVROLET SILVERADO 3500 Complaints

Dealership told me the throttle body failed in my transmission. I wanted it completely torn down to find the actual point of failure since it did represent the current recall on the truck that hadn't been done because the part isn't yet available. The transmission has been replaced for almost $10,000.00

2nd time I’ve had to replace def heater and tank. Truck goes into limp mode and limits the speed leaving a person stranded.

I haul vehicles for a living. My rear wheels locked up and my truck came to a complete stop while I was on the highway. Luckily I was able to pull over and no one was behind me. It has happened a total of 3 times. There is no fix for my recall yet. I’m terrified to drive, but this is how I make my living. What happens when it rains and my wheels lock up again. My life is on the line. I went to Chevrolet service they said they have no idea what could have caused this. Then a couple weeks later I get an open recall with no remedy. What am I suppose to do?

Transmission lock up traveling 45 miles an hour while acceleration up modest uphill grade pulling a 3000 pound trailer. The lockup was severe enough to cause passengers to lunge forward with seatbelt engagement. There was no loss of control of the vehicle; however, we did stop the vehicle to inspect it with no damage observed. We expected to see some. This event would have caused a likely loss of control of the vehicle if the lockup was for longer duration. Vehicle also had prior hard shifts that are still occurring. These hard shifts usually occur in the lower gears with acceleration and deceleration. Vehicle was taken to the dealership with an explanation of the event. There were no codes. The dealer recommended a transmission fluid change to smooth the shifting. This seemed to decrease the frequency of the hard shifts but did not eliminate them. The vehicle has not been inspected by police, manufacture or insurance company. The dealer did not do a thorough transmission inspection. I suspect they knew of this problem at the time of the transmission fluid change due to the current recall: Manufacturer Recall NumberN242454440 NHTSA Recall Number24V797

The contact owns a 2020 Chevrolet Silverado 3500. The contact stated that while depressing the brake pedal, the tailgate brake light failed to illuminate. In addition, the contact stated that while a trailer was hitched to the vehicle, the message "Check Trailer Connection" was displayed, and other unknown warning lights were illuminated. The vehicle was taken to a local dealer where it was diagnosed; however, the failure was not identified. The vehicle was taken to another local dealer, Davis-Moore Chevrolet (8200 W Kellogg Dr, Wichita, KS 67209) for a second opinion. The vehicle was diagnosed; however, the cause of the failure was not identified. Upon further inspection, the contact related the failure to Technical Service Bulletin: 20-NA-198; however, the second local dealer advised the contact that the fix might not repair the vehicle. The contact stated that the failure had progressed over time. The manufacturer was made aware of the failure. The failure mileage was approximately 26,000.

We tow a 2024 Grand Design Solitude 310GK with our 2020 Chevy Silverado 3500 diesel truck. We are getting frequent but intermittent loss of our trailer brakes during towing. As you can imagine this is a serious safety issue. We will be towing and receive a message on the display "Trailer Brakes Disconnected" then typically followed by "Service Trailer Brakes". This has been happening more frequently over the past 3 months. Imagine driving down a hill with a 15K pound rv pushing you and there are NO brakes on the 5th wheel. It is extremely scary and dangerous. I've researched on the internet and Facebook and there seems to be a "Technical Bulletin" from GM Bulletin No.: 23-NA-149 Date: September, 2023 recommending the replacement of the Trailer Brake Control Module. I've called to have the dealer replace our brake control module but it is not covered because it is a "Bulletin" and not a "recall". This is absurd and the manufacturer should take care of this known issue.

The contact owns a 2020 Chevrolet Silverado 3500. The contact stated while driving 10-15 MPH and approaching a stop sign, the brake pedal was depressed down to the floorboard, but the vehicle failed to respond. The contact made a left turn to avoid a ditch. The contact stated that the vehicle then rolled to a stop. The contact shifted to low gear, turned the hazard lights on, and was able to drive to the residence. Upon inspecting the vehicle, the contact noticed that the brake fluid was leaking. The vehicle was towed to the local dealer, where the passenger's side rear brake pads, brake disk, and brake calipers were replaced. The contact stated that the failure recurred while driving. The vehicle was towed to the dealer, where the driver's side rear brake pads, brake disk, and brake calipers were replaced; however, the failure persisted. The vehicle was towed to a second dealer, Duke Chevrolet GMC (2016 N Main St, Suffolk, VA 23434), where it was diagnosed that the passenger's side rear brake pads, brake disk, and brake calipers were severely damaged. Additionally, the failure had damaged the rim of the rear passenger's side inner tire. The vehicle was being repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 4,500. The VIN was not available.

Back window or back cab cover seal is defective and caused water to leak in the cab and soak the carpet in the entire floorboard there are water stains on the headliner mold growing under back storage compartment. There are numerous other reports of this issue on different internet forums. I have the truck at the shop with gm saying they will cover 25% of the costs. I feel this to be a manufacturer defect. This isn't caused by normal wear and tear.

This problem concerns faulty emergency brakes. The issue was discovered in the driveway, when I engaged the parking brake with the vehicle in park and my foot on the brake. The Service Emergency Brake light came on and stayed on. When the problem was investigated at the dealership, it was found that the brake pad abradable material had delaminated from the brake shoe and was floating loose inside the drum. This same condition was found on 3 of the 4 brake shoes. Based on the appearance of the parts it did no appear they fell off when the parking brake was engaged, but had been loose for some time. With loose parts floating inside the brake drum sooner or later they will move and could lock up the rear wheel. The Chevrolet service department did not seem to be concerned with condition. A big concern is that the parking brake needs to be engaged to discover the issue. Many people rarely if ever engage their parking brake and could be driving around with loose parts in their wheels. The fact that this happened in just three years indicates the parts were produced with a faulty bond material. The abradable should never just fall off. On a backup safety system that is required on all vehicles, this issue should be taken more seriously by the manufacturer

Tire size LT275 65 R20. Driving on Interstate Sunday September 24, 2023 the driver's side back tire blew out causing damage to the rim and side panel of the truck and bumper. We were pulling a 35 foot fifth wheel. We were able to successfully pull over to shoulder but had to wait over an hour for help. The blow out did do some damage to the fifth wheel also. Felt very unsafe until Georgia Champs arrived behind our camper. Our truck had about 16,000 miles on it and the tires. Last October the passenger side rear went flat (12,000 miles on the tires) and were able to pull over before a blowout. There we were stuck for about 3 hours on an interstate and had to change the tire ourselves because couldn't get someone out and felt unsafe waiting any longer.Both tires were on rear of truck and the blowout left over $6000 damage according to the estimate not including damage to the RV.We had no warning alert on the truck and a Goodyear salesman said the tires were not defective. But, we did not run over any apparent road hazard. We felt unsafe and were lucky the blowout didn't cause us to lose control of the truck or RV. Seems hard to believe this can happen twice in less than a year with pretty new tires. We always inspect the tires and make sure the tires are properly inflated according to the truck specifications.
