2021 Toyota 4Runner STEERING,SUSPENSION

I purchased the vehicle from a Dealer. During a test drive I noticed a shake in the steering wheel that represented a wheel balance issue. The dealership acknowledged that, according to their techs that it was a wheel issue. A new set of tires was ordered mounted and balanced. I have been dealing with the issue of sometimes excessive steering wheel shake and a feeling of unstable suspension issues in the front end during highway speeds of 60-70 MPH. In researching this model of Toyota it appears this is a well documented problem that has not been addressed by Toyota.

At speeds above 45 miles and hour, the steering wheel begins to nibble / shake which creates an unsafe driving situation. Vehicle has had alignment performed, and new tires balanced which still has not resolved issue.

Steering wheel shakes around 58-64 mph. Brought 4Runner in twice already with tires being road-forced balanced but nothing seems to work. I will be bringing it in again for the third time. This has happened with less than 100 miles, now with 2,700 mi.

*Steering shudder occurs when driving 55-70mph. *The shudder makes it feel as you have no control over vehicle, especially in wet/snow driving conditions. *dealer technicians have inspected multiple times with no fix. *issue began with in first 500 miles (brand new purchase).
