I’ve had this vehicle for about a year or less the car ran fine with minor problems that come with having a vehicle. Up until last week the car never showed any signs of a failing transmission, it went from running fine to shuttering and suddenly I wasn’t able to reverse. The check engine light never came on, I’ve did all my routine checks and more with the dealership I bought it from and was never told anything when the vehicle was brought in for inspections.

Vehicle displays Shift to Park message and audible tone after arriving at destination and attempting to turn off vehicle. Shifter indicates the vehicle is in Park and the transmission gears display on main screen also indicates the vehicle is in Park; however the warning message and audible continue to occur. Numerous attempts to move shifter through the different positions P-D1 are required to get the warning message to clear and the audible tone to stop. It has rapidly gotten worse in a matter of two weeks and I’m concerned that it will continue to get worse until I am no longer able to clear it leading to a dead battery, as well as other potential powertrain problems. A recent class action settlement unfortunately does not provide any relief to me for this known safety issue which already has a large number of NHTSA complaints filed pertaining to this powertrain issue. Given the number of complaints filed, I would urge NHTSA to force GM to issue a recall for this safety issue.

When my car is shift into Park and I tried to turn it off it’s giving me a “Shift to Park” message and the car continue to idle when it is turned off. I changed gears to try and take it off Park and then put back into Park and the same message occurs and it would not turn off car. After multiple attempts it finally turned it off. This has become more and more frequent. I cannot leave the car if it is not properly in park, still running with the warning bell beeping.

Frequent symptom is an "Action Required: Shift to Park" message on the dashboard. Which is preventing my vehicle from shutting down properly, and causing the battery to drain, and hinder my car's ability to start in addition to getting trapped in the vehicle because the vehicles fail to shift to the ‘Park’ position preventing me from being able to exit the vehicle. This is a known issue affecting various GM models which one being my 2018 traverse by GM but not willing to make official recall of the issue. There is a class action settlement due to this issue that was not privileged to me as an owner of a used vehicle included in this notice and have.

My 2018 Chevrolet Traverse, has unresolved safety defects that endanger occupants and other road users. These include transmission failure with loss of acceleration, “Shift‑to‑Park” malfunctions preventing engine shut‑off, inoperative blind‑spot/cross‑traffic sensors, faulty tire pressure monitoring, and an active oil leak from the timing gasket cover. These issues occur unpredictably during normal driving and parking, creating an immediate risk of collision, roll‑away, or engine fire. All of these issued happened within a very short time frame. June 2025 and I took my car into Crews Chevy, they want over $15,000 to repair. All of these items I have mentioned have numerous class action lawsuits (that they have won) for the year of my vehicle. I have spoken with GM (and have a case number) however, they are unwilling to repair, at no cost to me. I have an [XXX] daughter and work 7 days a week. I have been with out a car since [XXX] due to these issues. I do have the estimate for the repairs if needed. I do not have an actual repair invoice, as I wasn't able to afford the over $15,000 repairs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
