You’re cruising down the road, everything seems fine, and then—one of those dashboard warning lights pops on. Maybe it’s the check engine light, the service engine soon light, or the oil pressure warning. The car still seems to be running fine, so you figure you’ll deal with it later.
Bad idea.
Dashboard warning lights are your car’s way of letting you know something isn’t right. Some lights mean you’ve got time to fix the problem, while others mean you need to stop driving immediately. Let’s go over the most common warning lights, what they mean, and what happens if you ignore them.
What Do These Lights Mean?
Service Engine Soon Light
This one confuses a lot of drivers because it sounds serious but isn’t always an emergency. The service engine soon light typically means your car is due for routine maintenance or that there’s a minor issue like a loose gas cap or a small emissions problem. However, if this light starts flashing, that’s a sign of a more serious issue, and you should have it checked as soon as possible.
Check Engine Light
The check engine light can mean a range of things—from a bad oxygen sensor to a misfiring engine. If it’s solid, you still have time to get it checked out, but don’t wait too long. If it’s flashing, that means your engine is misfiring and could suffer serious damage. This is when you need to stop driving and get it diagnosed immediately.
Oil Pressure Warning Light
If this light comes on, your engine isn’t getting enough oil pressure. Running your car like this can seize the engine, which is about as bad as it gets. If you see this light, pull over, turn off the car, and check your oil level. Adding oil might help for a short time, but the real issue—whether it’s a leak, a bad oil pump, or a clog—needs to be addressed by a mechanic.
Battery Warning Light
A battery warning light doesn’t just mean your battery is weak—it usually signals a problem with the charging system, like a failing alternator or a loose belt. If this light comes on, you might only have a short time before your car won’t start. Get it checked before you end up stranded.
Brake Warning Light
If your brake warning light is on, you could be dealing with low brake fluid, worn-out brake pads, or even a serious brake system failure. Brakes are one of those things you don’t want to mess around with—if you see this light, it’s time to schedule a brake inspection before you find out the hard way that they aren’t working properly.
What Happens If You Ignore a Warning Light?
Some lights give you a little time before things get serious, but ignoring them for too long can lead to:
- Expensive repairs – A minor issue can turn into a major repair if left alone.
- Breakdowns – Some warning lights mean your car could stop running at any time.
- Safety risks – Brake and oil pressure warnings should never be ignored.
For example, if you ignore an oil pressure warning, you could end up with an engine that’s completely ruined. That’s not just an expensive repair—it might mean replacing the entire engine.
What Should You Do When a Warning Light Comes On?
- Don’t ignore it – Even if your car seems fine, the problem could be getting worse.
- Check your owner’s manual – Some lights mean immediate danger; others give you some time.
- Get it checked by a mechanic – A diagnostic scan can pinpoint the problem before it gets worse.
