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

1
Oil on the hot exhaust

An oil leak dripping onto the exhaust gives a hot, oily smell and sometimes a wisp of smoke.

Hot, oily smell
2
Overheating or dragging brakes

A sharp hot smell after a big hill or stop-start traffic can be brakes — or a sticking caliper dragging.

After braking
3
Slipping clutch (manual)

A burning-clutch smell under load, with the revs rising faster than the car, points to a worn clutch.

4
Electrical / wiring fault

A burning-plastic or 'hot electronics' smell can be wiring or a failing component — get this one checked promptly.

Burning plastic = check now
5
Drive belt or trapped debris

A worn drive belt, or plastic debris caught on the exhaust, can also smell like burning.

Is it safe to drive? It depends on the smell. Oil-on-exhaust or a faint hot-brake smell is a 'get it checked soon'. A burning-plastic or electrical smell — or any smoke — means pull over and call us, because electrical faults are the ones that can lead to a fire.

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.

Yes — we inspect and diagnose it in your driveway and quote the fix.
