Sounds like tire issues. I really like the Toyota FJ but it's not a truck. Whats the wheelbase on the FJ?
I've had support issues from dealers of all makes. It's difficult to find a great dealer. I just don't see that Toyota or Honda or any other Japanese make has better dealers than Dodge, Ford or GM. Just depends on where you live.
I had two horrible Nissan dealers, never did find one that would take care of problems without a fight. I had 1 horrible Dodge dealer but the
2nd one (Ed Moses in Phoenix) is awesome. I've not bought 4 Dodges from them and they just keep treating me right. Calls to DCX have also resulted in great service every time for all issues I've ever had.
