2018 Chevrolet Traverse

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.

Constantly displays “shift to park” when vehicle is properly in park and shut off which keeps the electrical system operating. Warning beeping (which can’t be turned off), interior and exterior lights, stereo, etc. continue for anywhere from minutes to hours until it randomly shuts down. Exterior lights have to be shut off manually. Meanwhile the battery is being drained and alarm system can’t be armed while warning beep is alerting passersby that the vehicle is powered on while unoccupied and unprotected. Other than waiting it out, the only option to shut the vehicle off is to disconnect the battery.

The vehicles fails to recognize it’s in park and does not shut off. Shift to park indicator turns on. Frequently have to park on incline and worried the vehicle will roll. The vehicle will not completely turn off and this has caused the steering to lock. When the vehicle finally turned off, then turned it back on we couldn’t get the steering wheel to unlock. Had to drive it with what felt like no power steering for a period of time. Shift to park indicator blinks and warning light appears that says no remote is detected, yet the remote is in the vehicle. Been in a situation where had to quickly get in to a Dr but the vehicle wouldn’t turn off so had to leave the vehicle running. At that point anything could happen, but had to take care of a sick child.

I have an exhaust issue with my 2018 Traverse that a Chevrolet/GM refuses to cover. I am getting check engine light that points to a leaking exhaust. The cause for these concerns could be a broken or poor weld with lack of penetration on the Bank 2 exhaust flex pipe bracket. It's a known GM issue on the 2018, 2019, 2020, 2021, 2022 models. GM has a safety bulletin PIP5681 and PIP5681A for this issue. N222385510 is the number for the 2021 recall. The dealership said it will not cover the repair because my vin has no associated recall. GM allowed the repair of the 2020 under the same recall number. This should be covered under Exhaust Warranty.
