i have an 06 4runner sports and mine front passenger side froze, the stealersjip quoted me at $1200 lucky i was still under warranty, the best part was my dealership decided to use my warranty for both calipers using my warranty cause they felt that the driver side was going to also freeze soon...
my 4runner does it also, but i noticed on mine that it did it more often when i would use lower grade gas, it does it alot less now that i put shell 93, now a days it only does it when the a/c is on
