my neighbor has a 2k bravada, except his is green though. only problems hes had with it in the 4 years that he has had it was the following:
2 flat tires
bad radiator cap
and he currently has this issue where one morning every now and then, he will come out to a dead battery
sometimes the rear hatch glass will open without reason
and he has one tire that has a slow leak, sometimes
it does seem a little underpowered IMO, but with a wheel chair lift on the back, it does alright given there is a 350 pound wheel chair on there sometimes. also, whatever you do, do not leave it idling unattended for long periods of time, it will heat up, sometimes past the point of no return. but other than that, the truck has served him well, almost making his AAA a waste of money.
btw, that smart trak all wheel drive is awesome, getting you out of prettymuch anything.
