Bad Odor

While your car might have a foul odor from old clothes or food containers, those aren’t primary concerns. But if you smell something odd or unfamiliar while you’re driving, that could indicate an issue under the hood — a coolant leak, mold in your vents or something else.

If you see or smell smoke while driving, immediately pull over to the nearest safe location and park. Smoke coming from a vehicle can sometimes be minor, but more than likely it indicates something serious. Whatever the problem, it needs to be fixed before you get back on the road.
