I too bought the lifetime alignment from Firestone over a decade ago. I still own the car I bought it for. The first free alignment went well with no problem. The second free alignment the car drifted bad afterwards, so I immediately brought it back and they adjusted something and then gave it back again. This time the steering wheel was almost at a 45 degree angle. I took it right back again and they fixed it, but they somehow knocked the driver side window off it’s track and wouldn’t roll up all the way. Never had this happen before. Then a few years later I took the same car car to a different Firestone location for an alignment since I had gotten new tires for it. Made an appointment with them, showed up at the appointment time and they told me they didn’t have time to do it that day and to come back tomorrow. I said okay will do, made the appointment again and then came back the following day. I arrived for my alignment appointment and the guy pulled up my info in the computer and said to me, while frantically looking around, “oh our alignment machine just broke!” I told him a phone call ahead of time would have been nice. I told him I didn’t believe a word he had told me and he just didn’t want to do the work because it was a lifetime alignment. His reply to me was “well you don’t have to come to THIS location”. Never stepped foot inside any Firestone ever again.
