My 2013 MKZ is a beautiful machine in every regard EXCEPT that anything under 50mph transmits the imperfections in the pavement directly to the driver. A smooth looking pavement that feels really smooth in my other vehicles (new F-150 and 2013 VW Beetle) feels like a washboard surface in this Lincoln ! The tires look great, I had the dealer balance them and rotate them. The car has just over 20,000 miles on it. It does not vibrate per se or seem to have tire imbalance. The tire air pressure is right on spec for all 4 wheels.
The thing literally acts like a feeler for tiny washboard imperfections in pavement. My F-150 rides far better below 50 mph on the same pavement. So does the diesel 6 speed Beetle !
Anyone else have this disease on an MKZ ? It is all-wheel drive and uses the Pirelli P245/40 ZR-19 tires.
My theory is that the idiot who decided to use 40 series tires [best when applied to a sports car track...] on what should be a super smooth riding near-luxury car needs to be lynched or else made to pay for converting my vehicle tires and wheels to a decent ride and feel. In other words I think the problem is very hard and stiff aluminum 19" wheels riding around 4" from the pavement on the hard sidewalls of 40 series tires. Anyone have a better theory ? ESPECIALLY do others have this disease !!??
Post script: I have pondered whether the "S" mode (sporty) might be locked on and not going off in the "D" normal driving mode. I see no difference in the two modes except that the shift points obviously differ and the steering turns burdensome in "S" mode. I see no difference in the shocks/suspension but that may be hard to detect.
