All I know denslexusgx470 is, I drove a 2005 Ford Explorer to San Diego from Claremont. There was no "clunk", no odd noises, no bucking or surging up hills, there was no shifting from 5th to 4th over and over again, like some have complained, even going up small grades(I have that problem too) and the Ford had 15,000 miles on it. My GX470 has 4200 miles on it and it has been to the shop 5 times already! The Explorer has not had 1 day in the shop, other than oil changes. I own a 2001 LS 430. It has not had 1 day in the shop for any repairs, no 1 and it has 50,000 miles on it. The Lexus did not put it's best foot forward when it produced the GX 470. Maybe we should call it the TSB 470..........
Yes it does seem disappointing that a nice, and expensive vehicle like the GX has this problem. But let's put it this way. Go visit a BMW or Benz forum, and they will have a whole shopping list of problems that most owners experience. If we ever read their problems, we'd probably feel bad that we complain too much about this clunk, that isn't a safety issue in the first place! ;) :)
