It's because it's a JAG . Ha ha . Just kidding . Who checked it ? I haul nothing but new cars for a living so hope this helps . A lot of high doller big horse power cars we get come and say on the dash " TRANSPORT MODE " . It cuts them back so we can't play with them . Why I don't know but I think your car has gone to this mode . The dealer and ONLY the dealer has the codes to change this . Anybody that scans the computer can't get in to this part .
