Chevrolet Traverse hesitation problems

Filed Oct 21, 2026 · Transmission · FL

-The Torque Converter Clutch (TCC) inside the automatic transmission is malfunctioning. It is experiencing a known defect outlined in GM Service Bulletin 23-NA-072. The vehicle is still being driven and is available for inspection upon request. -The transmission violently shudders and vibrates under light acceleration at low speeds (such as pulling out into traffic, merging, or navigating intersections). This violent, unexpected shaking creates a distraction, mimics the feeling of a blown tire or driving over a rumble strip, and causes hesitation in acceleration, which creates a safety hazard when merging with oncoming traffic. -The problem has been consistently reproduced by the owner. It matches the exact diagnostic criteria of GM’s active Technical Service Bulletin for TCC shudder. -No, it has not been inspected. - No check engine lights, warning lamps, or dashboard messages have appeared. The physical symptom is a severe mechanical shudder/vibration at low acceleration speeds, which first began appearing at approximately 75,000-80,000 -

The contact owns a 2018 Chevrolet Traverse. While driving at 5–8 MPH, the transmission slipped. After coming to a complete stop, the vehicle hesitated to accelerate for five seconds before jumping forward 3–5 feet. Several unknown warning lights briefly illuminated. Additionally, the vehicle failed to respond while in reverse(R). The contact expressed safety concerns for his child who occupied the vehicle. An independent mechanic was unable to diagnose the failure. The failure mileage was approximately 148,000.

The high-pressure fuel pump/fuel delivery system failed on my 2023 Chevrolet Traverse at approximately 47,480 miles. The vehicle generated diagnostic trouble code P0091. An authorized Chevrolet dealership inspected the vehicle and documented that the high-pressure fuel pump was “internally faulty” and required replacement. The vehicle and/or failed component may be available for inspection upon request, depending on whether the dealership retains the component after replacement. This failure presents a significant safety concern because the high-pressure fuel pump is responsible for maintaining proper fuel delivery to the engine. Failure of this system can result in hesitation, reduced engine performance, loss of power, stalling, or failure to start. A sudden loss of engine power while traveling at highway speeds, entering an intersection, or merging into traffic could increase the risk of a crash and endanger vehicle occupants and other motorists. The malfunction was confirmed by an authorized Chevrolet dealership through diagnostic testing. The dealership identified code P0091 and specifically documented the high-pressure fuel pump as internally faulty. To my knowledge, the vehicle has not been separately inspected by General Motors, law enforcement, an insurance company, or another independent investigator. Warning lights appeared intermittently prior to the diagnosis. The lights would illuminate and later turn off, despite the underlying malfunction still being present. I am concerned that a critical fuel-system component experienced an internal failure at only approximately 47,480 miles. I am requesting that the federal safety agency document and evaluate this failure to determine whether similar high-pressure fuel pump failures are occurring in other 2023 Chevrolet Traverse vehicles and whether this condition represents a potential vehicle safety defect.

Check engine light came on after feeling hesitation while driving and roughness while stopped. Diagnostic eval was done at shop and Evaporation Emissions Purge Valve was found to be faulty and replaced. Mechanic stated after the repair that this was a problem with certain year Traverses (unsure of which at the time) and an extended warranty was added that include 10 years or 150,000 miles.

Our 2019 traverse transmission around 130,000 miles started shuddering when slowly accelerating or driving. Not sure what causes this but I do know that it should be doing this as well as getting the Shift to Park message. I looked online and found that it's supposed to be the torque converter. I then contacted a transmission repair specialist and he stated that changing the fluid may make it worse or make it possibly fail altogether. Then I found a video about Shudder Fix and I added one of those packets to the transmission and it stopped the shudder but it now seems to be trying to creep back. This is a known issue with most people not being able to afford the $9000+ repair costs. The Shift to park issue is another issue that shouldn't be happening and the dealership will charge an arm and a leg for the repairs on this as well. Pressing the gear shift button about 5 to 10 times after shifting to park is a short term solution because that issue is tied to a spring action underneath the shifter to tell the car I'm in park. I found a bypass piece that is required to resolve the issue but I shouldn't have to do that to get this vehicle to work properly. Chevy needs to do a recall on this or they run the risk of having a bunch of them on the market where we all got rid of them and won't buy anymore Chevrolet vehicles. This is the second newer model vehicle I had from them. The first one was an Impala and the dealership didn't know why the screen would go black and cause the car to start hesitating horribly. So I left it with the dealership, they can have it back.

The contact stated that while driving at various speeds, the vehicle jerked significantly and almost stalled while depressing the accelerator pedal. The check engine warning light was intermittently illuminated. Additionally, the contact stated that the vehicle had failed to respond upon shifting to reverse(R). The vehicle was taken to O'Reilly’s Auto Parts; however, the failure could not be duplicated. The contact was informed that the diagnostic test confirmed that the vehicle was in drive(D), even though the gear shifter was in reverse(R). The dealer was notified of the failure and recommended a diagnostic test. The vehicle was taken to Kenny Wilson Transmission, where it was diagnosed, and determined that the transmission throttle had failed and needed to be replaced; however, the part was not available.

To the federal safety agency, I am submitting this letter as a **formal safety complaint** regarding repeated transmission failure in my **2019 Chevrolet Traverse**, which poses a potential risk to vehicle safety. In **December 2024**, while the vehicle was still covered under General Motors’ factory powertrain warranty, an authorized GM dealership diagnosed a serious transmission defect. Due to parts being on national backorder, the repair was delayed. When the repair was eventually performed, only partial components (torque converter and valve body) were replaced rather than the full transmission. Despite this repair, the transmission **failed again less than one year later**. In **November 2025**, a second authorized GM dealership confirmed that the transmission now requires **full replacement** and that the prior repair did not correct the underlying defect. The transmission failure has resulted in **slipping, hesitation, and loss of proper power delivery**, which creates a **potential safety hazard**, particularly during acceleration, merging, and highway driving. A loss of propulsion or delayed response in traffic significantly increases the risk of an accident. This issue was identified while the vehicle was under warranty and was not properly resolved. The repeat failure suggests a **systemic defect** rather than normal wear. General Motors has declined further assistance. I am requesting that the federal safety agency review this complaint as part of its monitoring of potential **powertrain defects** affecting vehicle safety. Vehicle Information: * Make/Model: 2019 Chevrolet Traverse * Manufacturer: General Motors * Component: Transmission / Powertrain Thank you for your attention
