When driving home the other night, I had my windsheild washers on intermittent and noticed that I could feel a vibration through the brake pedal everytime they "wiped." Is this normal?

 

I feel this too, and on loaners cars that i get too. I think it is normal as the wipers are connected to the brakes. For example, turn on the wipers when raining at a red-light, let off the brake and the wipers sweep.

 

I don't think there would need to be a mechanical connection to the brakes for the wipers to sweep when you let your foot off the gas, it could/should all be done electronically. Either way, I'm going to have the service guys take a look when I bring it in for its first service.

 

I have the same vibration, I think it's normal with the TLs, I found the same on a loaner car.

 

The wipers are mounted to the firewall, the brake pedal/booster is mounted to the firewall. Most cars will have some vibration transmitted. My 03' A4 did, my 05' F150 did, my TL does ever so slightly. Not sure theres anything you can do to stop it.
