2023 Chevrolet Silverado 1500: hesitation when accelerating

Filed Aug 25, 2026 · Transmission · CA

Description of the Problem: My 2023 Chevrolet Silverado 1500 has a recurring transmission issue involving hard shifting and shuddering during normal driving. The transmission frequently hesitates, clunks, or jolts when changing gears, especially at low to moderate speeds. These symptoms occur consistently and have worsened over time. Safety Concerns: The harsh gear engagement and shuddering make the vehicle difficult to control smoothly. It feels like something will break while I'm driving. The unpredictable shifting behavior feels unsafe in traffic, during merging, and when accelerating from a stop, or driving on the freeway. I am concerned this may be related to widespread transmission complaints reported by other 2023 Silverado owners, including valve body and TCM failures. Service History: I have not contacted my dealership regarding the issue. Why I’m Reporting: I believe this transmission behavior presents a potential safety defect. I am submitting this complaint so the federal safety agency can review it as part of ongoing monitoring of similar issues reported for this model year.

The 2023 Chevrolet Silverado 1500 High Country has experienced multiple powertrain and transmission failures beginning shortly after purchase. The issues include violent shifting, hesitation, and stalling, particularly while accelerating or decelerating. These malfunctions create serious safety risks—especially when merging, turning left across traffic, or entering intersections. The truck has been returned to authorized GM dealerships multiple times for diagnostics and repair. GM service departments confirmed transmission faults but have not successfully resolved the issue despite repeated attempts. The same problems reoccur shortly after each repair. At times, the vehicle has entered “limp mode” unexpectedly while driving, causing a loss of power. On at least one occasion, this occurred while driving on a busy highway, forcing evasive action to avoid a collision. Warning lights such as the “check engine” light and service alerts frequently appear before or during these incidents. To date, the vehicle has been inspected by GM-certified technicians at authorized dealerships. A case has been opened with GM customer care and BBB AUTO LINE arbitration has been initiated. The truck remains unreliable and unsafe to operate, especially with children on board. The risk of sudden power loss or drivetrain malfunction poses a clear hazard to occupants and other drivers.

On [XXX] the automatic tailgate on my 2023 Chevrolet Silverado began opening and closing without reason. This obviously poses a potential safety issue. After investigating, I found that there is a recall on 2020 to 2024 Silverados, recall # N232426400. I called Penske Chevrolet in Indianapolis to schedule a time for them to confirm the tailgate switch short and execute the recall service. I was informed by Penske that my specific VIN was not included in the recall. This is not acceptable. Reporting indicates there are a number of other Silverado owners in the same position. Please investigate, as the current state of the recall is most certainly not inclusive of all vehicles that are affected. There should be no hesitation by Chevrolet to broaden the recall INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Truck started hesitating for no known reason. No check engine light, nothing. Shortly thereafter, truck stopped shifting after I pulled out into a very busy intersection. Would not move briefly. I quickly put it into park, then neutral, then drive again, and was able to limp out of the intersection, just missing oncoming vehicles. I was then able to barely limp to dealership. Check engine light finally came on just before I got there. They say defective transmission cooler seal and lines. I have no idea. Truck in shop for 5 weeks and no idea of when it will return. According to various Chevy/GMC forums, it's happening to others. Some have had entire transmission replaced in a car less than a year old. Not being able to exit an intersection is a problem.

This has been verified by the dealers service advisor. The service advisor says they have no service bulletin on this problem so they have no solution for it at this time.

2023 Silverado 1500 3.0 Duramax. Transmission failure and engine overheating at 5k miles. I was towing a trailer when the 1st transmission failure occurred. The engine shut off, and said shift to N to start while coasting with loss of power braking. I was able to get started but transmission would slip when shifting above 1st gear. I had to tow to the nearest level point to safely park the vehicle, for fear of rolling backwards down 8% grade. At that point the computer was showing engine overheat loss of power warnings. GM roadside assistance towed to nearest dealer, refilled transmission with fluid, and put me back on the road for it to fail again in traffic (loss of power / unable to move). I have now been without vehicle going on 30 days and worry there is more wrong with the vehicle than just a blown transmission (latest GM diagnosis with no repair eta). For a few hours prior to failure I noticed what seemed like the transmission hunting for gears at lower speeds (0-25) with hesitation. Could have been slipping. And also noticed strange / louder than usual turbo noises. I worry the system is generating too much pressure or has mixed oil with coolant somewhere, based on finding atf, coolant, and engine oil near the overflow and all over the bottom of the vehicle. GM support has been atrocious and someone should step in.
