Resurrecting this thread from the dead to report that I picked up my car this evening after work. Haven't tried gassing it up yet but the dealer had put about 3 gallons in already and I can't believe they would let the car go if there was still a problem.

Kind of hoping I have another problem in the future so I have a chance of getting a rental '07 Sebring or Avenger to drive. Really am interested in what those cars are like.
