I' ve had this Lexus gs 300 about 11 months now and every once in a while when step on the brakes at a stop sign it will pull to the left or right, I've taken it to the dealer about 6 or 7 times but all they do is take it for a ride and of course they say it didn't do it for them. It is getting very frustrating to have this problem, it could very easily cause an accident by turning me into the car next to me. I understand some cars report the tires are responsible for this problem. They say they have checked everything that it might be but can't find anything wrong. You say you take care of all problems, but they wont do anything for me. I've been taking the car to the Lexus dealer in naperville il. I'm afraid this will be my last Lexus if this is the kind of help I get. My E-mail is [xxx] no accident so far. For the incident date I put the day we bought the car.

I own a 2006 GS300 AWD which I bought in Sept 2007, with 9000 miles. I had no problems with the car. In October 2008, while I was driving my car went flat. I went to rockville centre Lexus in rockville centre New York and they notified that I need not one but two tires. They stated that one of my other tires was not inflated but running on the run flat mode. I wonder if I bought the car in this condition and was not aware. I bought two tires the end price was $1,087. On March 21, 2009, while driving again low tire light comes on. I go to the dealership on Monday March 23, I need two new tires again. The tire was split, and it was not by glass or a nail. These tires are not fit for this vehicle or cheaply made. I am upset with Lexus and will never purchase Lexus again.

Dunlop 18" tires presenting with severe cupping on inside edge (discovered at 16K). Tires have approx 7/32 tread left otherwise (70%). significant safety issue as this wear is abnormal and isn't easy to see. Tire would come apart if not discovered and replaced. Lexus dealer agreed wear isn't normal but would only replace 2 tires. Lexus tech stated he's seen this before (alignment issues from the factory). Similar situation caused recall on LS460 models with dunlops. The GS300 should be recalled as well for alignment/tire checks before someone is killed. We were lucky to discover that our tires were unsafe as this is so difficult to see/detect.

Only 29,500 miles on tires that for the price should last many thousand more. Our tires looked like they were run improperly inflated and not rotated as recommended, but we have the service papers that prove otherwise. I have not had experience with dunlop brand tires and am quite disappointed with my only experience. I will never use this manufacturer again. My family is much too important to trust their safety with a company that doesn't take their responsibility seriously. Our tires started loosing tread chunks while driving 75-80 mph on the interstate. Only alert we had that this problem was occurring was a chunk that remained attached to the tire started hitting the wheel well of our vehicle. Upon inspection, we learned that two other tires had already lost pieces of tread and were worn down beyond what was safe.
