I had transmission serviced 9 months ago. Transmission has always shifted hard ( like it was going to shift up to next gear , but then downshift back ) Had serviced and a transmissiom check 5/21/26 and now saying I need it replaced. Truck has 106,000 miles. I’ve heard so many reports of Chevy Silverado transmission going out right after 100,000 miles. If it’s a common problem , I feel GM should recall and repair/replace.

I purchased this vehicle from Ghent Chevrolet in Greeley Colorado, since I have owned the vehicle I have had several transmission problems which caused the vehicle to stick in fourth gear and I have also have issues with the transmission violently shifting into first gear to the point it feels like I’ve been rear ended. I have had to replace the entire wiring harness and the water pump module as well as the thermostat module and the louvres in the front of the vehicle. I have service records for the vehicle for all the repairs and that state the amount of repairs has far exceeded the value of the vehicle and I’m currently having transmission issues again. Please help me find some sort of resolution to this situation! I have already tried to use and was rejected from the Colorado lemon law

I had been driving my truck for multiple days, after a knocking sound suddenly started from under the hood. It was evident at any speed that wasn't idle. There were no check engine lights displayed on the dash. The sound was annoying enough that I took it in. According to the dealer technician, the transmission pump "completely detached" and was "rolling around inside the transmission." They found metal fragments in the transmission fluid, and they declared the transmission a total loss. I have no idea how my truck was still driving, but if the transmission really had failed so catastrophically, I was driving a ticking time bomb. What if it decided to completely give out while driving my kids to school as soon as I made a left turn across traffic?

The defective manufacturer lifters on my 2020 Chevrolet Silverado 1500 went on my truck damaging the lifters, camshaft, oil pump and I'm sure more than that. I know it's an ongoing investigation/lawsuit with General Motors, but they need to held accountable and should fix this issue free of charge. Not everyone has $5k-$10k+ to repair their engine due to their negligence. Thank you

Internal oil consumption. With no oil puddled or spattered under the vehicle at time of purchase from a dealership or since then, a dealer certified vehicle with AFM at 153 miles from leaving the dealer the oil was non-existant on the dipstick. This directly indicates a TSB, Techical Service Bulletin involving the cause of failed lifters causing internal oil consumption and damage to lifters, cam shaft, push rods, rings and possibly more. This is a common result of the Active Fuel Management system which shuts off some of the cylinders for fuel economy for Chevrolet V6 and V8 engines. The problem was reported to the dealer by me imediately after the oil check at 153 miles and then towed to the dealer. As this is considered a catastrophic amount of oil loss, the vehicle could've been rendered inoperatable during operation in traffic and been a servere safty hazard. The dealer after initial inspection sent me a message that they think the problem is an undetectable small leak so they put some dye in the oil to check it. Which evades the actual internal consumption problem of 1.5 to 2 or more quarts of oil lost in just 153 miles by that ratio that would amount to 13 quarts per 1,000 miles. And helps them stall for time, to try to run out the very short 3 month/3000 mile drivetrain warranty. There was noticable erratic engine performance and some shudder but that shudder may have come from the transmission. The odometer read was 115690 at purchase and 115843 when towed=153 miles driven from when the certified inspection was performed for a loss of 1.5 to 2 quarts that I know of, it could have been much more oil missing. A suddenly inoperatable vehicle in town at intersections or on the highway at high speeds could be deadly for myself or others in traffic. I took and have videos of checking the dipstick to show it dry but it's an mp4 file which I don't see a place to upload it here. Available upon request.

During an extreme cold event in Interior Alaska (–44°F), the vehicle experienced a sudden emissions‑system failure that triggered an EPA‑mandated Limp Mode, limiting the vehicle to 5 MPH on high‑speed highways. This created an immediate life‑safety hazard because it was impossible to maintain a safe speed or exit the roadway due to snow berms. Prior to the failure, the vehicle displayed “Service Emission System” warnings and multiple DTCs related to the reductant heaters and sensors. A dealership technician later confirmed a “burnt pin” at the reductant pump connector, consistent with thermal‑electrical overload. This failure mode matches GM’s TSB 21‑NA‑006, describing connector overheating in cold climates. After the repair, the vehicle continued to exhibit safety‑critical symptoms, including harsh downshifts, delayed engagement, and jerking during deceleration, consistent with Recall 26V083000 (rear‑wheel lock‑up risk). The vehicle also continues to emit an electrical burning odor in cold temperatures, consistent with Recall N192206310 (block‑heater fire risk). The only GM dealership in the region issued a “Termination of Business Relationship,” preventing access to all recall and warranty repairs. This has created a 321‑mile “Service Desert,” making it impossible to obtain federally mandated recall remedies. The vehicle remains unsafe to operate due to unresolved transmission, electrical, and propulsion issues.

On September 27, 2025 while driving to my nieces soccer game my 2020 Silverado Traill Boss LT started losing power while driving. I was at a Red light when I felt the truck not properly responding to me pushing the gas pedal once it turned green. It slowly started accelerating and then with all the lights still illuminated on the dash, the truck completely stopped working with No response to the gas pedal. I had to let the truck coast forward while driving through an intersection. Thank God there was not that much traffic behind me and any cross traffic. I managed to pull the truck over stuck on the side of the road. My wife had to get a ride from a family member to reach the destination while I had to call a tow truck and have it towed home. Ironically, I believe the truck had just got out of Warranty, what a complete waste of thousands of dollars including the warranty that is always useless. I did not reach out to the dealership because I knew it was going to cost me an arm and a leg just for a diagnostic only for them not to find a problem. There was No Warning Light Flashing to notify me that my truck was taking a dump or any error code of any sort for a diagnostic to pinpoint the issue. I am surprised this has not turned into a Class Action Lawsuit (not yet anyways). My Father made me a Chevrolet person but with all the recent Engine/Powertrain problems with General Motors. I always believed the slogan "The longest lasting dependable trucks on the road". Tanks to YouTuber "@Donslife" for keeping the Public informed of all the latest updates with all these issues. This might be my last Chevrolet ever unless they could fix these issues and take some type of customer reimbursement/assurance/future or current incentives.

The vehicle experienced a transmission control malfunction related to a transmission solenoid (diagnostic code P0776). The transmission exhibited abnormal shifting behavior and drivability issues, prompting a warning indicator and dealer inspection. The condition affects the powertrain and could impair safe operation of the vehicle, particularly if shifting becomes unpredictable or the transmission enters a reduced-function mode while driving. The issue was confirmed by an authorized Chevrolet dealership, and the vehicle was subsequently deemed inoperable pending replacement of the required transmission solenoid component. The vehicle was inspected by General Motors on November 3, 2025, at which time GM confirmed that the required part was on national backorder with no immediate availability. The vehicle remains unavailable for use due solely to the lack of this GM-supplied component. A warning indicator and drivability symptoms were present prior to removal from service.

To Whom It May Concern, I am writing to formally file a complaint regarding my 2020 Chevrolet Silverado 1500 Diesel and to request immediate review and assistance from General Motors. I purchased this vehicle from a GM dealership in 2024 with approximately 70,000 miles for roughly $42,000. The vehicle currently has approximately 121,000 miles. Since purchasing the vehicle, it has suffered major breakdowns approximately every three months, requiring repeated costly repairs and making the vehicle unreliable for regular use. Most notably, the vehicle experienced a full transmission failure at approximately 103,000 miles — just after the factory warranty expired, requiring complete transmission replacement at my expense. To date, I have spent nearly $20,000 in repairs, including but not limited to: •Full transmission replacement •Two alternator replacements •Glow plug system failure •Coolant control valve failure •Engine control / computer module failure •Transmission cooling system failures •Ongoing electrical system issues •Additional drivetrain and mechanical problems These are critical powertrain, electrical, and engine management components — not routine maintenance items. The repeated failure of such systems strongly suggests underlying manufacturing or design defects. The vehicle has been properly maintained and serviced, yet continues to experience serious and recurring defects well beyond what would be considered normal wear and tear for a modern diesel truck. At this point, my total investment in this vehicle exceeds $62,000, and I am left with a truck that I cannot trust and that has become financially unsustainable to own.
