Just picked mine up Friday with 50 thousand miles on it, and a brand new suspension including air ride totally replaced. The trunk is tricky, it will stop working on you. If mis diagnosed, it'll cost you a fortune. If it stops going up automatically, check for slop in the fully raised position. excessive slop could result in the microswitch not being engaged. With the trunk up, push up to eliminate any slack, then push the button. If the latch moves, let the trunk go, and push the button again, Good chance it'll resume operation. There's 1200 bucks you don't have to spend on the dealer's attempt to jack you for unnecessary parts and labor.
