2018 Chevrolet Traverse

My 2018 Chevy traverse has a shift to park warning that continues to come on. It makes the vehicle not lock or park and you have to wait till it goes off. Sometimes it takes restarting the car and turning it off again before it will turn off. this seems to be a known problem when you look it up that 2018-2019 traverse are experiencing this. This should be a national recall for those years specifically.

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.

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.

Been receiving a "shift to park" warning message since last year. It seems to be a known issue, however nothing has been done about it. I've had trouble from time to time getting the car to recognize the Park position I've put the shifter in and occasionally have sat in my car with it on for minutes attempting what I can think of to have to car finally recognize that I shifted into Park. I had called a Chevy dealership near me who advised because my car is outside warranty it would not be a covered repair. I'm concerned as I have 2 young children and this is our family vehicle. I cannot leave a car running while I have my children inside or with them inside and me outside trying to turn the car off.

My 2018 Traverse has had the “shift to park” message displayed on the instrument cluster when I put the vehicle in park. Even though the red P for park is illuminated and the vehicle is clearly in park the ignition will not power off when you depressed the start/stop button. The vehicle displays the message shift to park. Now this has transpired for about 3 months and it is very frustrating when you can not park in your garage especially when storms are imminent from the forecast not to mention carbon monoxide poisoning! Now I or my wife have to continuously push on the shifter to get it to turn off. Or we have to turn the vehicle back on and try driving around the block or wherever we are at. Now not being able to turn your engine off is a definite safety concern especially when you have children and pets . This has been happening in GM SUV’s and is a known issue by GM but they seem it’s not a safety issue due it not causing any issues while driving. I had the vehicle repaired at our local dealer and it was $789 to repair the malfunctioning item. I have never heard of a shifter being defective in today’s modern cars. Whether it’s a mechanical issue or electrical issue it needs to be addressed. If I were to live an apartment dwelling with indoor parking I would have to find some other means to park if I could not turn my engine off. I have read numerous complaints online via forums which is very saddening when these automakers claim dependability with their very expensive vehicles. If the vehicle was built with defective or faulty components how does thst burden fall on the consumer?

Regarding the vehicle's functionality, the horn activated unexpectedly on or around May 2, 2025, sounding continuously for approximately 10-15 minutes while the vehicle was occupied. Subsequently, the horn has ceased to function. Furthermore, on or around May 10, 2025, the powertrain system indicator illuminated, leading to a diagnosis on May 18th that identified code P0455, indicating an EVAP system leak. Concurrently, the driver's side seat belt buckle has exhibited a tendency to detach and fall between the seat components, failing to remain in its intended position.
