Top 3 Signs That Indicate Engine Problems

As a vehicle owner, you know that your car engine is the heart of your vehicle. Without a healthy engine, your car won’t run smoothly, efficiently, or at all. To protect your engine, you need to keep up with your auto maintenance. This means never missing an oil change. Routine checkups to the mechanic extend engine life and help us catch problems when they are minor. Below are the top 3 signs that indicate engine trouble:

Illuminated Check Engine Light

Once the check engine warning pops up, you know that something is wrong. On one hand, it can be something minor like a loose gas cap. On the other hand, it can be a malfunctioning catalytic converter. Rest assured, our technicians can crack down on the check engine light with our state-of-the-art diagnostics equipment. When your check engine light comes on, please bring it to Preferred Auto & Fleet Service for testing.

Unfamiliar Noises

After driving day in and day out, you learn how your car drives and the types of noises it can make. When you catch an unusual sound, like knocking, grinding, and squealing, it means there’s something wrong. In specific, knocking sounds can mean that your engine components are bumping together. When you catch an unsettling sound, please bring your car to experts at our shop.

Poor Engine Performance

Although it's normal for a car engine to not run as strong or lively as it ages, sudden drops in performance can mean that it is more than age. If your fuel economy has worsened or you can’t accelerate like you used to, it could mean you have an issue with the engine. It is recommended that you keep an eye on your engine performance.


Your car will almost always signal to you when something goes wrong with your engine. If you’re looking for professional engine repair, look no further than Preferred Auto & Fleet Service. Please give us a call or visit our auto service shop in Thunder Bay, ON.
