AUTOMATIC CAR WAS "PARKED", TURNED OFF. KEY REMOVED, THOUGH IT WAS NOT IN P. EMERGENCY BRAKE WORKS AND APPLIED, BUT MAY NOT HAVE BEEN APPLIED ALL THE WAY. ROLLED BACK ACROSS THE LOW LOW GRADE PARKING LOT AND OUR WHITE CAR BUMPED A ... BLACK PORSCHE! DOESN'T APPEAR TO BE ANY DAMAGE OTHER THAN PAINT SMUDGE/TRANSFER FROM THE BUMPER. NORMAL SAFETY FEATURE WHERE THE CAR NEEDS TO BE IN PARK BEFORE THE KEY COMES OUT ISN'T WORKING PROPERLY. ANY ADVICE ON HOW TO FIX THIS? IF POSSIBLE MYSELF? IS THIS SOMETHING I CAN GET THE MFG TO PAY FOR? IT'S NOT UNDER WARRANTY. IT'S UNDER A 3 YR POWER TRAIN WARRANTY, BUT PRETTY SURE AT BEST THIS IS A ONLY RELATED TO A TRANSMISSION ISSUE, NOT DIRECTLY A TRANSMISSION ISSUE. NO RECALLS AS OF NOW FOR THIS ON MY VEHICLE. ANY ADVICE IS APPRECIATED.
