NHTSA Complaint #11582852 — 2019 BUICK REGAL

Hello, I am the original owner of my 2019 Buick Regal Sportback which shows a "shift to park message when I attempt to shut off the car and the car shifter is in the park position. I am unable to turn off lights, radio, or accessories. This condition runs down the battery and prevents me from starting the car as the shifter stays locked in position unless the car is running. This should be covered under the GM drivetrain warranty. Please help.
