I took my 03 RX300 in for its 25,000 mile service at dealer on the South Shore of Long Island NY just East of the Queens, NYC/ Nassau County Border. The dealer told me that my rear brakes were at 20% and needed replacing at a cost of $190.00. They also said that the cooling system needed to be flushed, and the fuel system needed to by cleaned. I question the last thing since I use Mobil gasoline exclusively and use Techron Fuel Injector cleaner every 6 months. I declined all the service.
My steering wheel started making "screeching" sounds when cold so I took my RX to a dealer on the "North Shore" of Long Island just North of Westbury. I told them to replace the rear brakes. They said that the cost would be $330.00, considerably higher than the other dealer. However, I told them to do it anyway. In the early afternoon I received a call from the service advisor informing me that the rear brakes were at 45% and definitely didn't need replacing!
Although this dealer is further from my residence and office, I admire their honesty. They are an "Elite" of Lexus award winner and I see why. I'm really surprised at the other dealer, however who apparently was recommending repairs that weren't necessary.
