STRUCTURE:BODY, AIR BAGS
Rear window is leaking onto the carpet beneath it creating mold and could allow water to enter the SRS module. Currently i have a tray blocking that water but without that the SRS system could be affected by the water entering the cabin through the rear window.

SERVICE BRAKES
Rear brake inner pads completely worn while outer pads look brand new at 35,000 miles. This appears to be due to the electronic parking brake not releasing quick enough but this condition almost disables the rear brakes and could cause an accident.

VISIBILITY/WIPER
I am writing to formally submit a complaint regarding a recurring and unresolved mechanical defect in my 2020 Chevrolet Silverado 2500HD, which I believe may constitute a widespread safety and reliability concern affecting this vehicle model. Since I purchased the truck in June 2020, I have experienced seven (7) failures of the air conditioning compressor system. The first six failures were repaired at authorized Chevrolet service centers, and the vehicle is currently undergoing a seventh replacement. All repairs have been documented and performed through Chevrolet dealerships, and I am attaching copies of the service repair orders for your reference. On July 24, 2025, a Chevrolet Customer Assistance representative, Chana Padgett, confirmed to me that the A/C compressor has been on national backorder, which I was told was due to the frequency of failures reported in 2020 Silverado 2500HD models nationwide. This points to a systemic defect, not an isolated case. The vehicle now has approximately 54,000 miles, and the repeated failures have resulted in: Significant loss of use of the vehicle Extended downtime due to backordered parts Decreased resale value and overall reliability Excessive repair costs, inconvenience, and loss of productivity The continued failure of a critical component like the A/C compressor affects not only driver comfort, but also visibility and ventilation—especially in southern states during peak summer months—posing potential safety hazards. I urge the NHTSA to initiate an investigation into this matter to determine if a recall or further corrective action by General Motors is warranted for the 2020 Silverado 2500HD model line.

POWER TRAIN, STEERING
Initially, turbo charger issues. Dealer after 2 weeks corrected issues with the turbo charger. We were provided loaner. Dealer took 28 days, the second time, to supposedly remedy Transmission/shifting issues. First we were told it was a valve port body. Then we were told they had to remove the pan, etc., all part of the process. Then the parts were on backorder. Finally, at the 11th hour, they installed a rebuilt transmission. Without a loaner for 2 weeks. Got the truck back and within 24 hours, the truck suddenly lost power steering while driving around curve at aprox.30 to 35 mph., check engine light on, power steering light on, trailer brakes warning light on, etc. Had it towed back to dealer in the morning and told it would be a priority. Called at 5pm. Truck has not been seen. It's not a car. It's a work truck. Seems the dealership is swamped with silverado trucks with similar transmission issues waiting for valve ports. No loaner vehicles to be had the second time after 2 weeks. Not sure what they will tell us tomorrow.

Having failure with the engine coolant control valve. Have taken my truck to the dealership for overheating and they always come and say that they can’t find an issue. They also informed me that I need to bring it back when my motor blows a head gasket which is complete bull.

ELECTRICAL SYSTEM
There is an issue with the wiring harness that causes vehicle to lose power. Dealership says manufacturer defect because designed with harness cover is too thin and is to close to engine so burns wires. Many other users have complained of this issue and is frequent in this model.

About 3 months after the 5 year 100000 mi warranty with only 70000 miles on the duramax diesel engine the exhaust brake part of the engine emissions/exhaust split along the weld. Have seen a number of these reported on the internet as well. Sounds like a manufacturing problem. The vehicle's check engine light came on and it's now at the dealership getting a new exhaust brake housing and bracket replaced. If this was in California or the 12 states listed would be covered for 8yrs/100000 miles.

POWER TRAIN
I had the lifters and camshaft fail in my truck as a result of the faulty fuel management system GM put in these trucks during these years of manufacturing. I was driving my kids to an appointment when they failed in the middle of the highway, leaving the truck unable to run. I have reported the problem to the dealer as well as reported to GM directly. I have spoken with 3 different garages, all of which have made it a point to tell me this is a common issue in these trucks. Prior to this happening, there were no lights on to warn me of this problem. The repair cost is $12,000 and that is to put the same parts in the failed the first time. I don’t know many consumers that can afford the costs of these repairs when GM knows this is an issue but refuses to do anything about it.

The contact owns a 2020 Chevrolet Silverado 3500. The contact stated that the check engine warning light was illuminated. Additionally, the vehicle later failed to start and became undrivable. The dealer was notified of the failure and an appointment was scheduled for diagnostic testing and for the manufacturer internal recall repairs. The vehicle was not diagnosed or repaired. Additionally, the contact became aware that the VIN was included in NHTSA Campaign Number: 24V797000 (Power Train); however, the local dealer was contacted and informed the contact that the dealer was not aware of the recall. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue via email, but no assistance was provided. The failure mileage was approximately 28,000. Parts distribution disconnect.
