How to Avoid a Car Fire

Quick facts

  • More car fires are caused by deferred maintenance than by accidents, according to the National Car Care Council.
  • Serious vehicle fires often result in a total loss because heat buckles metal beyond repair.
  • Improperly installed aftermarket electronics are a documented cause of vehicle fires.
  • A fire extinguisher should be stored in an accessible, secured location in each vehicle.

Over the last couple months the news has reported multiple car fires in our Portland Metropolitan area. These car fires were spontaneous and not caused by an accident.

According to the National Car Care Council each year they are seeing statistics that prove more car fires are occurring each year due to deferred maintenance rather than accidents.

Unlike collision damage that can be repaired, serious vehicle fires often result in a "total loss". These fires burn really hot and can reduce the strength of metal, fire can buckle body panels and this is almost impossible to repair satisfactorily. The cabin of the vehicle can melt, glass can be damaged and the burned wiring can also be very expensive to replace or repair.

These types of car fires can almost always be avoided with a few simple precautions. Having regular annual inspections performed on your vehicle, performed by a qualified technician is recommended. These inspections can be easily performed with an oil change or regular service, a quick lube service is not going to provide this, you really need to see your trusted repair facility who takes care of vehicles in their entirety. The following things should be inspected:

Preventative maintenance is really the key to keeping your vehicle safe, dependable and on the road with longevity. Preventative maintenance is like regular teeth cleanings and check ups at the dentist, they can prevent bigger problems down the road.

Frequently asked questions

Common questions

Which fluid leaks pose the greatest fire risk?

Fuel leaks are the most dangerous because gasoline and diesel ignite easily on a hot exhaust manifold or catalytic converter. Power steering fluid and brake fluid are also flammable and can drip onto exhaust components. Engine oil is somewhat less immediately dangerous but soaks into debris and insulation that can smolder and ignite. Any fluid leak should be located and repaired promptly, not monitored until the next oil change.

Why does a dirty engine compartment increase fire risk?

Accumulated oil, grease, and road debris on the engine and surrounding components act as fuel. A small fuel or fluid leak that might otherwise drip harmlessly onto the ground can instead saturate oil-soaked debris near a hot surface and ignite. A clean engine compartment also makes it far easier to spot new leaks before they become serious. The contrast of fresh fluid against a clean surface is immediately visible.

What type of fire extinguisher should be kept in a vehicle?

A dry chemical ABC-rated extinguisher rated at least 2.5 lbs is suitable for a vehicle. BC-rated extinguishers work on fuel and electrical fires but not combustibles, while ABC-rated units cover all three classes. The extinguisher should be mounted in a dedicated bracket rather than rolling loose in the trunk. Check the gauge periodically and replace it if the pressure drops below the acceptable range marked on the gauge.
