Mine is grabby when it's wet out but I've found that the brakes work a lot better in slippery mode. Can tell instantly when I forget to put it in slippery.
A 22 with only 4k miles? Wow! Mine makes knocking noises once in a while but it sounds like the valves. I have 31k miles on it and had 2 Blackstone oil tests and both were good.
Do you have a defrost spot built into your windshield? Maybe it's setting it down into that? My XL doesn't have a defrost except the heater and doesn't skip down when it gets to the bottom of the stroke.
You're waiting for down payment money? I hope it's not too long because they may sell it out from under you.
My dealer was good but I had to pick it up within 2 days.
