I had a Ford Windstar that the dealer bought back preemptively while I was starting the Lemon Law process...that thing was amazingly bad. Fast forward about 6 months, saw the new owner, asked her how she liked the van, she said she had NO trouble with it at all, it was perfect and she was very happy with it. I don't know if I had finally sorted out all of the bugs (including 3 transmissions) or what, but it surely didn't run for 6 months at a time for us without ending up at the dealer for a failure or two. It was so bad that the loaner we had for 60+ days also started acting up, so we had to get a different loaner. Point being, if the car has lost your confidence, dump it and go on with your life. It's not worth the stress and worries.
