Vehicle constantly drift to the left which make it very unsafe because the driver is in a continuous correction mode to remain in one lane - can inspect anytime, alignment and tire rotation has been complied with at least 8 times within the last 3 months by Toyota dealer and firestone conclusion alignment is ok sometimes with minor correction. I'm constantly holding pressure on the steering to the right and left to remain in my lane doesn't matter about the road. The problem is worst on multi - lanes in the same direction with tractor trailers passing due to air current.
