Brake Warning Light
In the past couple of weeks, the brake warning dash light has flashed at me twice for about 3 seconds each time and I can feel the brakes slip a bit. The strange thing is, it has happened on the same street on the same slight incline as I approach a stop sign. It hasn't happened at any other time on any other street. The owner's manual says to get the vehicle in for service asap, and I will, but I was wondering if anyone has had a similar experience?
It's just strange to me that it has happened at exactly the same spot both times. I'm thinking there might be some anomaly with the street itself that is causing the brakes to malfunction at that exact spot.

Anyway, it happened again yesterday afternoon - this time at a different location, but again the warning light came on while coming to a stop on an incline. The car goes to the dealer service tomorrow morning. I'm not particularly fond of my dealer's service department, so I anticipate they will come up with the standard, "We can't find anything wrong" response. I'll let you know.

I'm not sure what this means?

Then just print out the recall, if you are consistent with the symptoms, I would mention that.
Each time that light goes off, your ECU time stamps it. Tell them to pull up your ECU output and find the time stamps that each of those lights came on to confirm it.
Either way, I would get this addressed. If it comes up again, grab your phone quickly and get a picture or video of it. Always helps to have visual evidence.

The warning light I get says "BRAKE" in large letters with a beeping alarm sound. I also have PCS, but if I understand correctly that warning would be "PCS." Also, I have not had PCS engaged, nor were there any other vehicles around when the brake warning light came on. It has happened as I press the brake pedal to stop.

Take a look at pages 303 and 304 in the manual. What you describe appears to be the PCS brake warning. You can turn PCS off, but it re-engages every time you start the car. Could be a fault in PCS, or take a look at 305 for some "conditions" that can activate it unnecessarily.
