The brake light issue isn't likely the the brake switch (since it sounds like your other brake lights are working properly). It's likely a bulb in the third brake light. When the filaments get old they sometimes lose and regain contact as the car vibrates on the road. Change the bilbs and see if the problem goes away. If it doesn't, look for a bad wire connection around the third brake light. Also, have someone verify the third brake light isn't working from the back of the car when you see the alert, it could be a bad sensor.
I will assume you have checked all of the fuses inside and in the engine compartment. The brake lights are on a different circuit from the speedo cluster. The key switch is about the only thing that everything is connected thru. If the third brake light works but not the others, does the turn signals work ? Some of this could be a faulty connector on the back of the cluster.
if the third brake light is working and the left and right brake lights are not than the most likely problem is the turn signal multifunction switch.
If the third brake light is also not working and the bulb is good than check the brake light switch located above the brake pedal under the dash. There should be power on one wire all the time. There should be another wire that powers up with the brake pedal depressed. If no wires power up with the pedal depressed than the switch is bad.
I can get you specific wire information if you need it. Just let me know.
