I have always owned Lexus cars, but the newer models have gotten so unnecessarily complex that they are prone to VERY expensive failures. I could go on and on, but take for example the most recent failure of the Navigation unit. At only 28k pampered miles, the screen just up and dies. Now, not only does this screen control the GPs, but it also controls the climate control/defrost, rear view camera, Stereo including radio/CD changer. So this one gadget failing has rendered the car undriveable (no defrost.) To get it replaced is 6k....SIX thousand dollars (and not covered by warranty even though the car only has 30k miles!!) This is BAD engineering plain and simple.
Radar Cruise control and six speed trans.
How about standing behind your products. Having a 6k repair bill on a car that has only 30k on it is Chrysler level quality as far as I am concerned. The car should NOT lose its ability to defrost the windshield just because their shoddy gps unit flakes out.
