I took my vehicle in for Electronic Air Suspension repairs. The problem was diagnosed and a recommendation made. The recommended part was replaced. After driving for less than two weeks, the same "EAS" FAULT sign came on again. After taking the vehicle 4 times back and forth within a month, and paying for a new part every new visit, I decided that this must be a case of "bait and switch". I decided to seek a second opinion from another shop, who found the original replaced part to be non functional. I discussed returning all the alleged replaced parts to the Service Shop, and getting back everything I paid for labor. The Shop refused accepting the parts. Since then, I have initiated a dispute on my credit card account, and have made my intensions known to the shop. The general manager threatened having their lawyer pursuit me. Do I have a recourse?
