Went to my dealer after waiting two months for the seat rail assembly to be installed to cure the rocking seat problem. I was told it was a 1.5 hour job. Was told it was ready after 45 minutes. I asked the adviser what was done. She said there is a TSB that said instead of replacing the rail assembly they replaced the tilt pipe housing assembly on both seats. Seems to have fixed the problem, I'll take it out tomorrow for a more aggressive test. Anyone else have this done?
