One problem related to transmission slip out of gear has been reported for the 2002 Lexus RX300. The most recently reported issues are listed below.
2002 Lexus Rx300 automatic transmission issue. Have been reading on the internet as well as this site (16 total complaints about transmission/power train for this particular vehicle). Just this morning, my wife (principal driver of this vehicle) tried to put the vehicle in reverse (located inside our home garage). The vehicle will not reverse. From reading other complaints, it seems that this is now a more common issue with this model of Lexus than ever before? the danger involved in having to play with a gear shift; shifting back and forth from park to reverse, or reverse to drive, just to move into gear is a hazard and danger for a vehicle particularly housed in a garage. I'm also learning that others have experienced this model of Lexus SUV jumping out of gear and locking up the axles while the vehicle is in motion. Lexus is not an inexpensive vehicle, and owners should expect more from a vehicle of this price range and overall quality otherwise.
