Took my 5thgen in for its first tire rotation its a 2010 10k miles. Nearest dealership is 1.5 hrs away. I watched them throught the window they ran the nuts up and started torqueing all the tires. I sat back down and within minutes they came to the lobby with the dreaded...Mr. Smith can you come with me please and handed me a busted lug nut....The tech was beside himself he said I have never seen anything like this I cannot tighten down of your studs they all just spin. I put the torque wrench on the a few lugs and they just spun and then it just busted off. He said I am not touching any more lugs. So I said exactly how many did you get to torque down..he replied none of them they all are spinning. I got on the phone and called the Toyota dealership...the service writer said basically sorry about your bad luck but if I would drive it out he would look at it. I replied I cannot drive the vehicle that far the wheels could fall off. He said pay a tow truck to haul it up there then. I said listen there is evedently something going on here and they need to come get it and warranty the work out. He replied absolutely not. I asked to speak to the service manager told him the what was happening. Though he did agree that this was strange he would like to see it but it would not be covered under warrenty work. So filed a complaint with toyota today left the car at the tire shop. Having the local part houses overnight the 24 lugs in to get the car back on the road but wow is all I can say.....
