Final Comment: Truly Final !
AS you al know I changed tires from the horrible Dunlops and also reduced the
wheel diameter from 19 inch to 18 inch.
After getting the drivers seat, steering
wheel adjuster and seat memory fixed for the third time. I was able to drive an "Air Ride" equipped passenger car. The air ride mainly improved other areas of ride performance not the jar associated by me with the Genesis ride, so I have abandoned that plan.
So far I have carefully driven a 2009, a 2010, 2011 and a 2012 Genesis over a variety of roads.
Then I drove a VW 2012 Passat, A 2012
Lincoln MKZ, a 202 Toyota Avalon and a Chrysler 300 with 20 inch wheels and one with 18 inch wheels.
All OVER THE SAME ROADS at the same typical velocity and all at factory recommended tire pressure.
All this was a serious and studied endeavor I was accompanied by 2 additional passenger in the car at all times. Carefully attention was given to the test drives.
ALL the cars felt the same on the section of the freeway chosen, SMOOTH.
On the section of surban and city roads selected all the Genesis felt the same with very very minor differences: Unsettled, Jarring on tar strips and manhole covers and really bad on small pot holes. ( no large pot holes were tested).
In order of increasing all around comfort the cars were: VW,
Lincoln, Toyota and Chrysler. The Avalon was easily the least reactive to pot holes and Tar Strips but the Chrysler although a bit more reactive to those, was a better all around experience. So I traded the Genesis in on a Chrysler 300 Limited. So now I have no reason to post complaints about the Genesis since I don't own it anymore.
It has been a pleasure being on this forum, I personally wish each and everyone, all the best, good luck and farewell. Gripper
