I know this has nothing to do with your problem, but have you had an issue when you apply the brakes you hear a clicking/popping sound. I've been hearing one every since I bought mine in Jan of this year and have taken it back 4 times. After they thought they had fixed the problem it came back again. Now they are telling me its suppose to make the sound. Everyone else is telling me no way. Suppose to take it back again this Wed. Thx
Never had the issue you describing but the 07 ES's do require frequent brake service due to front rotor warping.
