3 Common Engine Problems and their Cause

CBAC Jan Engine Service 1Unless you drive a new car every day, engine performance and reliability are concerns. Although some engine issues are bigger than others, the vast majority can be avoided by regularly taking care of maintenance issues. Today, our expert technicians at Christian Brothers Automotive in Concord, North Carolina want to share three common engine problems car drivers may run into and what causes them.

Engine Won’t Start

It’s perhaps one of the most nerve-racking and common issues, nearly every driver has experienced that sinking feeling of turning the key and the engine failing to start as normal. You can usually conclude it’s a battery problem if the engine is clicking but there’s no crank. When there’s a crank, but still not start, you are looking at a fuel or ignition problem.

Some other typical reasons engines fail to start include:

  • Low or discharged battery
  • Corroded or loose battery cables
  • Starter motor relay failure
  • Ignition switch failure
  • Faulty fuel pump
  • Clogged or dirty fuel filter

Service Engine Soon Light


Your vehicle is equipped with a “Service Engine Soon” light to let you know if any fault has been detected by one of the sensors connected to the emission, engine or powertrain controls. Our professional technicians at Christian Brothers Automotive Concord are ASE-certified and are trained to analyze the trouble codes from your car’s onboard electronic control module to narrow the clues down to the specific cause.

These are frequent reasons your “Service Engine Soon” light would have turned on:

  • Loose or missing gas cap
  • Worn out and damaged spark plugs or wires
  • Electronic control module failure
  • Defective distributor or coil packs
  • Emissions control fault – such as the oxygen sensor
  • Poor Fuel Quality

Engine Overheating

While overheating engines are most common during the hot summer months, that doesn’t mean it can’t happen in the winter. Most cars come with some kind of temperature gauges or warning lights to tell the driver if the engine is in danger of overheating. To prevent engine overheating, the best thing you can do is keep the engine’s coolant in good condition and have it regularly serviced.

Overheating is most frequently caused by the following problems:

  • Damaged or broken thermostat
  • Dirty or low coolant level
  • Non-functioning cooling fan
  • Failed radiator hose
  • Internal or external coolant leaks
  • Defective radiator cap
