Why does my car smell like burning?
A burning smell usually points to oil dripping onto a hot exhaust, overheating brakes, a slipping clutch, or an electrical / wiring fault. The type of smell helps narrow it down — but a burning-plastic or electrical smell is the one to treat promptly, since that's the kind that can lead to a fire.
The most common causes
An oil leak dripping onto the exhaust gives a hot, oily smell and sometimes a wisp of smoke.
Hot, oily smellA sharp hot smell after a big hill or stop-start traffic can be brakes — or a sticking caliper dragging.
After brakingA burning-clutch smell under load, with the revs rising faster than the car, points to a worn clutch.
A burning-plastic or 'hot electronics' smell can be wiring or a failing component — get this one checked promptly.
Burning plastic = check nowA worn drive belt, or plastic debris caught on the exhaust, can also smell like burning.

Common questions
It depends what's burning. An oily or hot-brake smell is usually a 'check soon'; a burning-plastic or electrical smell means stop and get it looked at, since that's the type that can lead to a fire.
After a long hill or heavy traffic some brake smell is normal as they cool. A constant hot smell can mean a sticking caliper dragging the pad — worth checking.
