It continued for about 30-40 minutes and would come on everytime the brake pedal was pressed and would continue to stay on until release, the issue came back ONCE today when I had to brake hard at highway speed.

Kind of alarming to me as this is the first problem I have encountered with the car. I know my brake pads are due soon and my front rotors are warped. My brake fluid was just changed about 10,000 km ago and is full as I dont think it has anything to do with that.

Let me know if you figure anything out as brakes are something you cant put off
Are you absolutely sure your brake fluid reservoir is full? The condition you are describing would indicate to me it's slightly low. If it's low and you think it should be full because it was recently serviced, you may need to check for leaks.

And just a word to the wise: If you go fill up your reservoir when the pads are REAL low it is going to overflow when you put new pads in. Now I am just messing with you - Go easy on me.

I am 100% sure that it is full not because it has been recently replaced but because I have checked with my own eyes.

The problem WENT AWAY and has yet to occur again.

The ONLY TIME (except for once on the highway) that this occur is when I had to leave my car out in the cold overnight and when it was filthy covered in salt to the point where the car looked white rather then gold.

Maybe salt within some brake components has somethign to do with it?

There are 2 types of brake warning light. The "BRAKE" in red or a picture of a car in "YELLOW". Which one is on?

The one in red, you need to check your brake system.
The one in yellow, you need to check your brake lights.

I actually have the exact same problem, just got the 90k service done, but for some reason, my mechanic told me it didn't need both bottles of brake fluid I got from
sewell which the guy from sewell recommended for 90k, so right after the service my brake light would come on as I brake, now it would come on while I brake when it's cold out, it doesn't do it when it's warm...weird

i second the same problem. mine just started doing this 3 days ago. randomly (red brake light) comes on when the brake foot brake is off and shuts off on its own. doesnt seem to depend on the regular brake pedal to be pressed or depressed when driving, it just goes and comes when it wants, but more often, it stays on. i will take the help in this thread into consideration and check my fluid/pads.
