They CAN'T void your warranty, especially if the owners manual says it's okay in an emergancy or once in a while. What they CAN do is tell you to that if you continue to use it, and it damages your engine (which is doubtful and they would have to prove it), they can decline the repair, but they CANNOT void your warranty.
I have seen people put regular gas in instead of premium (in the WRX) and they say it makes the car hesitate....haven't had experience with the Tribeca yet. If you can stand they way that it drives, do it once and a while. You have to drive the car.....
