2008 Toyota Avalon Sedan XLS 4dr Sedan (3.5L 6cyl 6A)
DANGEROUS in even a lite snow
 Mpg has dropped 10 mpgs, and even in a dusting of snow once a wheel spins the computer takes over and gets no power to the wheels, yes I repeat no power to the wheels. You can hold the gas to the floor and the engine will not go above an idle and the transmission goes into neutral on its own.... junk.
