I did a quick google, and found that GM and Toyota both had had recalls for window problems, GM had recalled 1.54 MILLION cars for possible fires in the 3800 series engine, etc etc.
No where did was I able to verify the broad claims you are making.
You must remember that recalls are not always done when they needed to be done. GM didnt recall those turd 3800 series II engines, probably because it was not deemed to be a safety issue. Turd issues may be conveniently swept under the carpet.
Toyota could be as bad...I just dont know. We now have two, and have two remaining GM products. With only a couple of years on the first Toyota, there has not been a single glitch. The other one is too new to evaluate.
