Re: Steering wheel vibration
If you had it stored (parked) for a while, the tires definitely get flat spots. They have to warm up well and roll for a while to return to normal. In the interim, it will cause a vibration or thumping. I noticed this on both my XFs yesterday, when I pulled them out of the garage for their first drive since November. At low speeds, no problem; over 50 I started to notice the flat spot.
