After picking up a screw in a tire on our brand new car, we took our car in to see if it could be patched or if the tire needed to be replaced. I asked to see the screw out of curiosity, but the screw brought out to me was not only completely different (and much larger), it also showed NO wear from being driven on. I told them this was not the screw in my tire, so the technician went and got the tire and was able to provide me with the actual screw from the tire. He then told me that I actually had two screws in the tire, which was not the case. After speaking with the manager, we were able to determine that the technician had apparently put an additional hole in the tire which did pierce the belt (the screw that WAS in the tire had not). I did get a full refund and didn't have to pay for the new tire. However I would be very cautious bringing your car here for any kind of service.
