2018 Chevrolet Traverse

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)

The contact owns a 2018 Chevrolet Traverse. The contact stated that while attempting to park the vehicle, the gear shift selector was shifted to park(P), and the message "Shift to Park" was displayed, and the contact was unable to turn off the vehicle. The contact stated that after shifting to park several times, the failure self-corrected. The contact stated that the failure was intermittent. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure, but no assistance was offered. The contact indicated that the vehicle had previously been repaired for the same failure. No further information was available. The failure mileage was 84,000.

The vehicle has a design flaw which causes a bracket which connects the 2 pipes which connect to the catalytic converter to fail. Once the bracket has failed, the rear catalytic converter is allowed to vibrate more than designed, adding extra stress to the catalytic converter. Over time, this additional stress causes the catalytic converter to fail, releasing harmful gases directly from the engine exhaust manifold with carbon monoxide and other harmful gases into the air and into the passenger compartment of the vehicle. This is a know issue that GM has recalled on the 2019 (recall N212356540) and 2021 (recall N222385510) model year Traverse. Other years may have also been recalled that I am not aware of. For some reason, GM has neglected to take ownership of this issue on the 2018 Traverse which shares the same design as both the 2019 and 2021 model years. I have gone to the dealership and contact Chevrolet's customer service multiple times and they refuse to reimburse me for the cost of the necessary repairs. I have already purchased the broken and necessary, ancillary components and repaired the vehicle myself because I did not want to pay the dealership over $2000 in labor which they quoted me.

The contact owns a 2018 Chevrolet Traverse. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted and jerked abnormally. There was no warning light illuminated. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure.

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.
