I purchased a slightly used 2013 VW Touareg VR6 LUX approx. 4 weeks ago. Upon driving home from the dealer I noticed that between the speeds of 60 and 75 mph the steering wheel would shake back and forth. This was confirmed over many miles and all types of road surfaces. The car would also pull to the right as well as exhibit a vibration in the seat. The car has now spent 3 weeks at the dealer and after approx. 20 tires and countless road force balancing the issue still exists. VW, in an apparent attempt to limit their liability, is blaming the tires. They now refuse to attempt any more repairs and have told me to pick the car up. They acknowledge the issue to still to be present.
Styling and comfort
Come clean with the owners who are experiencing the steering wheel shake. Stop trying to band aid with tires and hope they go away until their warranties run out. Man up and fix the problem or if unable to repair then do the right thing and refund or replace.
Try re-torquing the wheel bolts yourself. It works. Unfortunately, many service dept personel don't always use the correct tool or method for installing wheels. They just tighten the bolts without using the required star pattern, and without torquing to exact specs (133 ft-lbs) for the Touareg.
