Your Car Shouldn’t Smell Like That

Your vehicle can tell you a lot about what’s happening under the hood—and sometimes, it does that through smell. A strange smell doesn’t always mean there’s a major problem, but certain odors can be warning signs that your vehicle needs attention. Here are some common smells drivers may notice and what they could mean.

Burning Rubber

A burning rubber smell can come from several different sources. A slipping belt, overheated component, or even something contacting a hot engine or exhaust component could produce a rubber-like smell. If the smell continues or becomes stronger, it’s a good idea to have the vehicle inspected.

Burning Oil

A strong burning oil smell may mean oil is leaking onto a hot engine or exhaust component. Oil leaks shouldn’t be ignored. Low oil levels can eventually cause serious engine damage if the vehicle continues to operate without enough lubrication.

A Sweet Smell

A sweet smell coming from the engine compartment may be related to coolant. Coolant leaks can occur from hoses, the radiator, the water pump, or other parts of the cooling system. If your vehicle is also overheating or you notice coolant under the car, have it checked promptly.

Gasoline

A strong gasoline smell shouldn’t be ignored. It could indicate a fuel leak or another issue with the fuel system. Because gasoline is highly flammable, a noticeable fuel smell deserves prompt attention.

Musty or Moldy Smell

A musty smell inside your vehicle may come from the cabin air filter or moisture inside the HVAC system. Replacing the cabin air filter and checking the ventilation system may help resolve the issue.

Burning Plastic or Electrical Smell

A burning plastic or electrical smell can indicate an overheated electrical component, wiring issue, or another problem. If you notice this smell along with smoke or electrical problems, stop driving the vehicle and have it inspected.

When Should You Have a Strange Smell Checked?

If a smell is new, persistent, unusually strong, or accompanied by another symptom, don’t ignore it. Your vehicle may be giving you an early warning that something needs attention. MotorAbility can help diagnose unusual smells and other vehicle problems for drivers in Green Bay, WI.
