Steering Pinion Shaft Problems of Lexus IS

The problem Is a previous TSB on Lexus's website called 9lc special service campaign for the electric power steering link assembly. The steering Is very unsafe with random wandering between lanes and Is very notchy with rapid movement once a certain angle Is reached. It has a dead zone of about 20 degrees on each side and every imperfection in the road causes the car to wander but the steering Is not giving any feedback to indicate its wandering out of the lane you just have to watch the edges of the lane and correct it constantly. 6 Lexus dealerships were unable to diagnose the problem and end up costing be 5000 +dollars trying to fix the problem replacing the suspension, balljoints, lower control arms, rack and pinion + ecu, inner/outter tie rods and an intermediate steering shaft. Nothing has resolved the probem and they can't seem to fix it or diagnose it. They just say trade it for a newer one. There are many Is250/350 owners between 2006 and 2009 that are affected by this and many have had a serious accident because of this especially caused by long hwy ramps and exits in which the steering binds to one side and you have to violently correct it or it will hit the curb or wander into another lane extremely unsafely. This Is not a comfort Issue, it Is purely a high level safety concern as there Is no remedy and Lexus dealerships and corporate refuse to acknowledge a problem at all. Please investigate this. I think it Is very dangerous to other drivers. I drive a Honda accord and Toyota camry and have never experienced this with either of them and they have over 220k miles each. I have visited 10 independent shops as well and got 10 alignments from dealerships to performance shops and no one Is able to figure out why this Is happening or how to fix it.
