What causes a 2001 Suzuki Grand Vitara to veer all over the road at highway speeds?
I don't know, but mine does it too...kinda scary sometimes! I
would check the tire pressure first if that is with in spec's then
i would have the alignment check as well as the susspension I have
this problem too. It seems to me that it happens more often when it
is windy. I've had my Vitara blown across lanes on often on windy
