Success!!!
Originally when the TSB # came out I called my local dealership, not the same one I purchased from, and explained the lumbar issue and mentioned the TSB. The service manager said they would have to replicate the issue to replace the neccesary parts and in addition that my '10 TE was not covered by the TSB number I had referenced. Knowing that my case was not too extreme and I only felt it after my daily 200 mile road trips, I was not to confident to take it in only them have them tell me they could not replicate the popping.
When the TSB text came out and I saw that my VIN was covered I became a little more confident as well as pissed with a certain service manager. This week as my odometer rolled past 34k I became a little more motivated to get this fixed while it was still gratis. So I drive over to the the aforementioned dealership and explain the issue and hand them the TSB. They tell me to wait an hour until the tech can take a look and try to replicate the issue. Hour later I get called in and told the tech could not feel the popping even after driving around the block a few times.
The manager have me the opportunity to drive the tech around and "show" him the issue. I was not really sure what this was going to accomplish, but then I thought what the hell. The tech was pretty cool and I explained the issue again and that I was trying to get this done while I was still under warranty. When we pulled back into the dealership he got back into the drivr seat and said "Now I feel what you are talking about, let's get those parts ordered." Not sure if he felt it or not but whatever... Appointment on Saturday!
Austin area people with the same issue pm me and I'll let you in on the dealership.
