i had this problem couple years ago, so i took it to the dealer and paid around $1000 to get it fixed, and now after two-three years, the light has came back on, i mean i was driving and it just lit up and now it wont go away, i contacted Toyota and told them this problem and they told me it can't be the same problem again, if it is i ain't paying a damn cent, so I'll have to go to the Toyota dealer and get it checked, but I'll appreciate any help i can get here.
