I called Customer Assistance again at (800) 992 1997. I told the agent that my dealer didn't want to do TSB 18-008-06. He gave me the normal line about if the vehicle is not exhibiting a problem they don't need to do the TSB. I asked him to take a look at the TSB in question. After he read the Diagnosis section, which says, "If a vehicle is in for service perform the repair procedure", he called my dealer. He told the dealer that we're seeing something different in that section than is on most TSBs, and that's what made the difference. My dealer said they would do the work. I also mentioned to the agent that lots of us are having the same problem getting this TSB done.
