Mike, I suggest that you have a long talk with the Service Manager at your dealer. Discuss the details of each recent service visit/receipt and the reason specific work was done. If it seems that they were proceeding on a trial-and-error basis then insist on credit for any/all unnecessary work (parts & labor). Hopefully the dealer or you have the old parts ... I always ask for the old parts, just in case. I'm curious why you accepted the car back after the first service appointment if it was still hard to start. If the problem wasn't corrected why pay the bill? Are you sure that you posted all the relevant details so that the forum members can advise you properly? How far apart and how many miles between visits? Did the Service Advisor discuss what had been done to your car at each visit, and recommend other repair work that youu declined? Our local dealer's Service Advisors communicate the what and why of recommended service items, and whether the items are critical or not. I do the simple items myself.
