Engine Problem #1: Engine Won't Start
It’s perhaps one of the most nerve-racking and common engine problems, 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
- Neglecting oil and filter changes
- Catalytic converter failure
Your motor oil has a big responsibility. The oil lubricates the engine, cools engine parts, keeps the engine clean and prevents deposit buildup. Unfortunately, even the best oil eventually degrades. When the oil becomes old, it will begin to fill with sludge and debris. This has a negative effect on your engine. When you change the oil, the contaminates are removed along with the old oil and filter. Your manufacturer will have a recommended oil change schedule, but a good rule of thumb is to have the oil and filter changed every 3 months or 3,000 miles.
The catalytic converter is a vital part of your car’s exhaust system. The catalytic converter breaks down dangerous chemical emissions from the engine and routes them away from the driver. Regular wear and tear will happen, but driving habits, road conditions and vehicle type can also affect the catalytic convertor. If you notice rattling during acceleration or braking, or any loud noises during the drive, it’s time schedule an exhaust system check. The catalytic convertor can fail due to a leak caused by rust or corrosion, or as a result of internal plugging caused by excessive carbon buildup. Regularly scheduled maintenance checks will ensure the entire exhaust system is functioning properly.

Engine Problem #3: 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
