I agree with Larry. This is the only car I've ever owned that has had such a problem with warped rotors.
When I bought my car two years ago, I replaced the front and rear rotors and pads.
One year later, the front were warped. I replaced them.
Now, my rear rotors are warped and need replacing. It's driving me crazy!!!1
