I've noticed that too. Feels like the seat is shift side to side. It was more noticeable when I took it to the track than everyday hard driving though.
My family has been buying Fords from Leif Johnson Ford since 1987. I have a good relationship with the sales manager there so he always does me right on new cars.
I purchased one of these in case I needed to install it at some point.

I don't have it installed now but its a really easy installation.
My car has been doing the same thing and it's only when coming to a complete stop at lights from low speeds. I tried to get my dealership to take a look at it a few weeks ago when I got my oil change done but the guy who does brakes wasn't in yet so I have to try some other time.
It's Memorial Day weekend so people will not be available for a meet up. I for one am going to be at a friends for a BBQ we have every year and wouldn't be available either.
I've only seen one other TY 2015 and it was a convertible parked at one of the builds at Dell. I'm not a convertible guy but the TY convert showed me just how much I don't like them. TY with a black top looks terrible IMO.
I've been using Leif Johnson Ford for years. They really take care of me well so much so that they took care of rental when I had a flat and even after putting the wrong tire on the car they were able to get the correct one...
I might be able to make it out for once. Nothing is planned as of yet for me so just need to know where and I can most likely be there. I agree with xTestfigtx, somewhere north would be better since SXSW is happening downtown.
The WiFi that is part of the stereo in the car requires a connected phone (or usb WAN device 3G/4G) to be connected and then the connection is shared out to the rest of the passengers. The car does not have built it 3G/4G if that's what you are thinking.
A MiFi from Verizon might work in...
There are plastic screws you remove to get access to the battery. If you go checkout the video posted for installing the hood actuators you can see exactly where the battery is.
