I have a 2002 Toyota Sequoia sr5 2 wheel drive - the vsc and trac off lights come on and off randomly. I have taken it in several times and complained of this issue. The first time (with about 15000 miles) I was told front brakes needed replaced - which I did. Problem returned and when I take it in, dealer says they can't duplicate the problem, so there is nothing they can do. There is something wrong, they are ignoring it.
