Awhile back, probably about 5months ago i had to replace a bearing. I got it done at a local shop that was had good reviews and friends have had some experience with them. When i got the bearing done from them the day after i noticed the vdc, slip, awd lights were on. I didnt think it was a big deal and would get it checked out by infiniti but i became a little busy with school and such and never got around to it till recently. Infiniti says that the speed sensor was broken when the bearing was replaced. I have no proof that the lights were on after the bearing was broken except for my own word, and infiniti. A guy at infiniti said that its their right to back up their service of work and pay for the damages which is about a grand for infiniti service. Im thinking that i should call infiniti again and ask if it is for sure and proof that the speed sensor was not put back in place correctly and was smashed and not due to anything else. Anywho, im not sure about how to talk to the auto shop i went to that they ruined the speed sensor and is their job to back up their work. On their site they say they back up their work for life.
