Like many others that I know that own a lexus sc430. I think I have a mold problem. I have heard of people becoming very ill from car. I also smell a problem with ac and have condensation on inside of windows.
I have experienced sudden unintended acceleration on nov 28, 2009 in san diego. Braking did not help. Car went over street divider in opposing traffic lanes. I was lucky that there was no traffic.
