Chrysler Tri city Chrysler dodge Sold a brand new car and it was a lemon Kingsport Tennessee

We have bought this car in April and had it in the shop over 6 times for bad fuel Eco and a miss they have replaced parts on this car several times this last time a teck came to look at it and stated it need a software up date which they don't have they may have one or may not that it is misfairing and it gives the car bad gas mileage we had bought this car for that purpose and know we are stuck with a bad car Chrysler refuse to handal this problem even though they sold us a defected product I have to pay mouthy on for it not to perform the way it should Chrysler refuse to call us back and the dealer that we purchsed it from Tri City dodge of Kingsport tn does nothing to help with this problem they also stated that there are other dodge advengers out there with this same problem and chysler refuse to do anything about it but they shure took tax payers money to get them out of a bind
