I have a 2007 Toyota Camry I bought brand new in 2007; 4 months ago, maybe longer, I was informed by my mechanic of 20yrs. that I have Warped Rotors. I told him my steering wheel vibrates when I reach 60 or higher and when I decrease speed, whether it be by taking my foot off the accelerator or using the brake. How long can I drive on these Warped Rotors, and how does this happen?? I have been a Camry owner since 1987 and never had this problem. Thanks for your help and your time, and I sure hope the answer is from Tom and Ray.
