Last year I purchased a packet of coupons for 8 oil changes for $125. I took my truck in for the first one and they changed the oil and called me when it was ready. I went to pick it up, and the guy behind the counter told me the front end needed a complete rebuild and it was unsafe to drive. This was a shock to me as the truck is older, but it only has 48K miles on it. I told him I would take it to my normal mechanic and let him do the work. He does the front end work on all of my vehicles. The guy at the dealership told me I could not drive MY truck off the lot or he would call the police on me. I called a friend, went and got my car hauler and my big truck, went and picked up my truck and went straight to my mechanic. He looked at it, told me one of the ball joints had a torn boot, he could order the parts and have it fixed in a day after getting the parts. I asked him if it was safe to drive, and he told it should be fine to drive for months. Everything else was fine except for the one torn boot. When I mentioned why I brought it on a trailer, he said he has had several people come in from the same dealership.

Is it legal for them to threaten to call the police or even keep you keys? I have already paid them for their service. I have to take it in for another service soon, and I am wondering if I should call the police if they try and keep my truck again. I was thinking about reporting it stolen if they refuse to give it back.
