I have driven my RX for almost a week and no problems.
dourdanlover, i have the exact same situation with my rx300. its very annoying. i took it to the dealer and was quoted almost the same price ~1300 dollars to clean the rush in the rear if the sensors break. if they can save the sensors its a 300 dollar job. i just wanted to know if its still driving well and did you think paying the 1200 bucks was worth it??
