I have an '07 3.0si with 19K miles on it now. I had the tailgate latch problem and the dealer replaced the latch. The noise is slightly less but defininatly still there! This car is making me crazy! I'm trying so hard to like it and feel good about my purchase. Unlike many of you, I drive a car for much longer than average. My last car, a 2000 528i, I drove almost 8 years! The only time that car saw a dealer was for oil service and brakes! My son drives it now, it looks and runs like brand new!
This X5 on the other hand, has been to the dealer more times in the first 6 months than the 528 has ever been in 8 years!

Besides the tailgate noise, the rear entertainment DVD was replaced because it was "sticking", now the speakers buzz if you play DVD sound through them! Suspension parts replaced for excessive noise and banging sounds, the plastic on the steering wheel is starting to peel. The door panels have been removed and "realigned". Just a bunch of things. All the while, I REALLY want to like this car!!

My apologies for the rant! The question I intended to ask is if anyone knows a fix for the noisy tailgate. If your sitting in the backseat it sounds like the tailgate is not closed all the way, just squeaks and rattles!! Should I take it back to the dealer or is there a DIY fix?
Thanks so much!
