I have a 2006 Toyota Sienna le ,which have airbag flashing & brake system problem. This airbag problem started within 6 months of purchase & 2 times it was fixed by Toyota dealer . But the problem is still exist. When even I make a complaint to dealer they are telling they can't find it. This airbag flashing light comes on when in driving & will stay for 1 hr. Or some times stay for 5 days etc. Toyota still not diagnose these problem . Now my vehicle is less than 32000 miles . Once in every month airbag sign will get on. And braking issue still present.
