in the morning i was driving my car then had to brake really fast at a red light. i had my heat on and after breaking really fast smoke started to come from the vents. it wasnt alot but you could of seen it and it smelled like rubber/oil burn. it is the first time car did this. i have no idea whats going. i look for leaks cant even find a single drip.

 

maby some oil from the crank case spilled into somewhere, which then burned up, and the smoke eventually made it up through the heating system, then out the vents...

 

Scary.

 

maybe just overheated stock brakes, happens when i use the crap out of my brakes, espcially if your vent is turned to outside.

just do some hard braking in a parking lot from high speed and see if thats the problem.
