To start off, my wife drove the new car off the lot. I noticed that the rear hub cap was out of round so the dealer replaced it. After that,with the car having about est. 25000 miles started to get a vibration in the car. I took it to the dealer and they told me the tires were shot. Which I did not think that. So, I bought a complete set of tires. Vibration still there, so I took it back to the dealer, they took it to a goodyear dealer here in town and had the tires balanced on the car. The goodyear dealer told them that I had a tire on the left rear out of round. I took it back to the place where I bought it and told them the problem. They replace it and the vibration still there. Since then, the toyota dealer replace the front tires and told me that I should replace the rear (brand new) tires. So, tired of messing with this problem, I did. Vibration still there, Now that I have replace 3 complete sets of tires, balanced 3-4 times, realigned 3-4 times, had the brake rotors turned because of uneven braking. The DAMN vibration is till there when I go 42 mph and 72 mph. Now on top of that, I have contacted Toyota's regional office made a claim of things going on. Since then, they have contacted me by phone several times but still not call to say lets fix this problem. Oh yea! I have not told you, I now have a squeel in the front left wheel now. It has been 1 week and a few days since I turned in the claim and still no phone call. Wow! ESP As I was typing this the regional office called me and I told them, still not fixed and no call from anyone but you!
