Toyota sells lemons!
 I purchased a 2007 Avalon after my 2006 was declared a total loss. My car was trouble free until 55,000 miles when the check engine light went on.  The AC was broken, O2 sensor, gas tank and a list of other items brought the repair bill to $4500. If it were not for CA emissions warranty, I'd have to pay the entire thing. I'm still on the hook for $2,000. The dealer was fine but I'll never buy a Toyota again- my Chrysler was more reliable.
