I have had my 2010 RX 350 for about 4 months now. In total, I have gone back 5 times for 3 different defects on the new model. I have had Navigation, A/C Radio problems (which all have TSB's issued by Lexus now). Not to mention the exterior defect of the driver side bumper I now have, due to wind damage from long distance driving. The front corner bumper is "popping" out of place every time I go on long drives. I'm going to have to wait until the next time I go in for service to have it checked out, I'm tired of driving loaners and paying for a new car. Overall, I am very disappointed that Lexus would send a car out on the road with so many problems.
