It’s not surprising that cars often develop issues — they are complex machines, after all. However, it can be difficult to spot engine trouble if you don’t know what to look for, especially if your vehicle isn’t showing any apparent problems. Here are the most common engine problems and how to know when it’s time to take your car to your mechanic.

Leaking Oil

One of the most common car engine problems is an oil leak. Oil leaks can be caused by various things, such as a cracked engine block, a faulty gasket, or a loose oil drain plug. If you notice your car leaking oil, take it to a mechanic immediately (or have it taken if it won’t drive). Otherwise, you could end up doing severe damage to your engine.

Low Oil Pressure

One of the most common car engine problems is low oil pressure. This can be caused by various mechanical problems, including a dirty oil filter, an oil pump that isn’t working correctly, or worn-out engine seals. If you’re experiencing low oil pressure, it’s essential to get your car checked out by a mechanic as soon as possible.

Rough Idle

A rough engine idle can be caused by several things, including a dirty air filter, a vacuum leak, or a problem with the ignition system. If your car is having trouble idling, it’s essential to get it looked at by a mechanic right away. Ignoring the problem could lead to more serious engine damage down the road.


Another common car engine problem is overheating. When your car overheats, it can cause several problems, including engine damage, decreased fuel efficiency, and even complete engine failure. To avoid these problems, keep an eye on your car’s temperature gauge and pull over if you see the needle moving into the red zone. If your car does overheat, turn off the engine and let it cool down before continuing your journey.


One of the most common causes of car trouble is engine misfiring. This can be caused by various things, from a faulty spark plug to a dirty air filter. If your engine is misfiring, it’s essential to diagnose the problem immediately. Ignoring an engine misfire can lead to more significant issues down the road, so it’s best to nip it in the bud right away.

Electrical Issues

A dead battery is a common car electrical issue. If your car won’t start, it’s likely because the battery is dead or too weak. You can try jump-starting the car, but you’ll need to replace the battery if that doesn’t work. Another common electrical issue is a faulty alternator. If your car’s headlights are dimming or flickering, it could indicate that the alternator is going bad.

If you notice any of these issues with your car’s engine, see your mechanic as soon as possible.
