Bought the vehicle brand new and have been dealing with a steering wheel/vehicle shake ever since. The vehicle feels out of control around 55-65mph(like death wobble) and the ride is rough at any speed over 50mph. This has been a serious issue on the highway with instances of crossing lanes because of lack of control over steering. No warning lights have ever come on. Been to the dealership many times complaining about the issue just to be told that the "problem can't be replicated". I have taken it to several tire shops as well to have the wheels/tires balanced but nothing seems to help. I even bought new wheels and tires just to see if this was the cause and still no solution. This is a serious problem that thousands of 4Runner owners are experiencing and Toyota needs to get to the bottom of this. This absolutely should not be happening on brand new/modern day vehicles. I believe this is a multivariate issue causing the shake - a mix between wheel/tire balance, steering column, and possibly the drive shaft/differential/CV components. The problem must be big if Toyota continues to deny the problem year after year after year.
