Have taken this vehicle multiples times to Toyota dealers looking to address a front suspension problem. It feels like the steering wheel is shaking a little bit when is being driven at slow speed over uneven street pavement surface (small potholes) it feels something in the suspension is loose and it wobbles from left and right. I always feel it on the steering wheel. They haven't been able to determine what is the real problem arguing they don't feel any wobbling on the vehicle.

Steering TSB by Toyota: while driving vehicle and turning corners, I felt poping clunking noise in steering wheel. Sometimes made steering wheel vibrate. Instead of just a service bulletin, this should be a recall since Toyota has re-designed the failing component. Took vehicle into dealer to have fixed. Would have paid full repair price but was able to negotiate a discounted price for vehicle with only 52,000 miles. Component should have easily lasted over 125,000 miles. May be the same as your 10075792 record.
