The first step failed on getting my 09 a TSB. I called the main hotline, expressed my concern and whatnot. The lady was very nice but said as of now, even though VIN and leaf part numbers match, she can't do anything until they update the TSB to include 09's. She did say she'd forward the old TSB to the important people to encourage them to update the model years.
Try #2 coming next. She recommended I take it to the dealer with a full load so they could see the problem. I plan to borrow a buddies four-wheeler, hit some dips until it bottoms out, and take it in. I'll nicely rant about safety concerns, this is what I bought it for, yadda, yadda, yadda.
Any other advice?
