What would cause a burning smell that smells like plastic or rubber? No noises associated with the smell....it is a Pontiac Sunfire.???

Is your emergency break on? (Embarrassingly enough, this happened to me.)
Incorrectly routed, adjusted(tensioned), missing or worn drive belt(s); Incorrect belt tension will allow belts to slip; Loose or damaged belt tensioner will allow belts to slip; Worn or damaged idler/tensioner pulley; Spark plug or coil wire(s) making contact with hot engine; Corroded, broken or poorly connected battery cable. burning rubber smell is not caused by brakes 99% of burning rubber is caused by a faulty fan belt. get it checked for signs of wear and tear and correct tension, other 1% would be a tire wearing on something or you locking up brakes and skidding tires check fan belt

This happened to me last weekend and I was wondering if it could be that I whacked one or more of my wheels out of alignment and the brake (pads?) were sticking/rubbing when I turned or after braking.

I did have a new cooling fan put in about a month ago. Maybe they messed the belt tension up....? Parking brake was not on, checked that. Battery cables and spark plug wires looked okay. It almost has an electrical smell to it. I can't quite put my finger (nose!) on it.

My guess is the blower motor for the heater.

Default Nevermind!

Got on the ground today and examined the underside of the car. Looks like we ran over a plastic bag. Thats all! Thanks for the input.

Same thing just happened to me. I thought it was a belt at first too.
