This vehicle was great right up to about 75,000 miles. Then things went poorly. I have had electrical problems, the check engine light keeps telling me that an o2 sensor is bad; changed two times. Then at around 105,000 the tranny started acting weird. Stuck in second gear, O/D light flashing. I have the 3.8; many mechanics have refused to tune it up because it is so hard to work on.
