Consumer Description

SHIFT TO PARK - I originally thought I was turning the car off too quickly. I would put the car in park and hit the button. Then I would get an error message (with Loud beeping) "SHIFT TO PARK." The car will not turn off completely or stop beeping until i turn it back on, and shift into drive and back into park. This last week the problem has escalated and keeps giving me the error message. I have had to leave my car with loud beeping and unlocked. I am driving with a battery charger hoping I will not have to use it. I am shocked this is NOT a recall.
