A good engine is the cornerstone of any vehicle. Ideally, your engine will last for years with proper maintenance. However, this isn’t always the case. Whether through wear and tear, manufacturer error, an irresponsible previous owner, or any other number of reasons, our engines occasionally need help.

Nothing sinks a heart faster than seeing that check engine light — especially if it’s flashing for urgency. But did you know other signs can help you catch a problem before it’s too late? Four, to be precise.

Letting an engine malfunction continue can cause damage to your car— or harm to you and your passengers.
