05 & 06 Wrangler has recall for the exact problem my 03 has. Parking pawl slides out of the brackets and then vehicle won't go into park allowing it to roll into danger and possibly kill someone. I have watched several videos on this issue and the 03 is the same as a 05 and 06. This is just as dangerous on the 03 as it is a 05 and 06 and potentially cause an accident and kill individuals.
