2006 Lexus RX 330 6 cyl Automatic 28,000 miles
I have been to the dealer several times with this problem and they cannot find anythign wrong. When my car has been sitting in the hot sun and I start it up, it makes a squealing noise. The noise goes away after 5 seconds. I notice it is only when I turn on the ignition. I live in South Florida and my car is parked in the hot sun almost everyday. This has been going on for about 1 year.
