It is almost a year since my problems going to florida .About a month ago had engine light came on and dealer put on computer update and light went off, A few weeks later dealer changed oil and fuel filters and also updated the computer again. By the time i got home (15min) engine light back on. Back to dealer problem with exhaust senser. Took 2 weeks to come from Philadolfia and is being installed today. I guess they still have not figured out how to get a part from one place to anothervery quickly. Just got bill for senser part no 55502921 under warranty and it different then last year 55590140 maybe it is updated one
