I got a flat tire and I had to drive on it for 75-100 ft cause bastards drive too fast for me to pull over. Well, after fixing the flat the Brake warning light is lit up. And I heard metal grinding for a quick sec after I accelerated after fixing the flat. The car feels sluggish and there was a strong burning smell when I got home. I want to know would this be covered under the factory warranty even though this more of my fault? I doubt the tire would be, I am more concerned about the Brake light. Otherwise I won't mention that I had a flat tire.

You probably set your emergency brake while changing the bad wheel? Did you release the e-brake ALL the way after you were finished? The only other reason for the Brake Warning Light to illuminate is that your brake fluid level has dropped to near the "MIN" level.

*Hits head* Stupid me, I forgot about that. I was so relieved to to have changed the tire and not get hit by zooming traffic that it slipped my mind. Luckily I live only 500 feet from where I had a flat tire. There was no puddle by my tire so I wasn't leaking any fluid. Thanks!
