The check engine light came on in my 2023 Chevrolet Spark and I don't know if it's something serious or if I can keep driving. I don't notice anything weird in how it's running, but I'm worried it might be expensive to fix.
That light means there's a fault code in the engine, but it's not automatically an emergency - you can keep driving at normal speed! What you do need to do is go to a mechanic shop so they can read the code with a diagnostic computer, because it could be something simple (like a gas cap that's not closed properly) or something that needs attention, but without knowing the code it's impossible to know what it'll cost.
When that light comes on, your car is detecting that something in the engine or emissions system isn't working the way it should! The good news is it's not automatically something that'll leave you stranded on the road, but you do need to get to a mechanic to have them read the fault code - that's going to tell you exactly what's going on. The trap a lot of people fall into is ignoring it thinking that if the car runs fine there's no problem, but some issues (like a broken sensor or a loose gas cap) can get way more expensive if you leave them unchecked! Better to go soon than wait for something else to break down.
This happened to me a few months ago with my car and I freaked out, but it turned out to be just a loose gas cap! The diagnostic scanner picked it up in seconds. What I'll tell you is don't ignore it for too long because even though a lot of times it's something simple like that, it could also be a bad oxygen sensor or something with the emissions that, if you leave it for a while, ends up costing you more in the end.
The most important thing is to go to a shop with a code reader (pretty much any shop does it, often for free or really cheap) so they can see exactly what code popped up! Once you know what it is, then you can decide if it's urgent or if you can wait until next weekend. In the meantime you can definitely drive normally, the light doesn't mean your engine's going to blow up or anything like that!
Your Spark's diagnostic system detected something that fell outside normal parameters, but here's the important part: that light could mean anything from something as simple as a loose gas cap to more serious issues in the emissions system or sensors. The truth is, without a diagnostic scan you won't know what's actually going on.
The good news is that in most cases you can keep driving without a problem, just shouldn't ignore it for too long. I'd recommend that in the next few days you go to a shop and ask them to run the scanner on it - it's super quick and cheap (often free). That'll give you the exact error code and then you'll actually know if it's something that needs urgent repair or if it can wait a bit.
One thing I noticed is that people often think any dashboard light means a huge expense, but honestly most of the time it's relatively affordable stuff. Either way, the sooner you get it checked, the better, because sometimes those sensors or minor issues can get worse if you leave them unattended too long.
The main thing is that it's not a guarantee that it's something serious, but you can't ignore it either. Most likely you'll need a diagnostic scanner to read exactly what error code your car is flagging, because that'll tell you whether it's something minor (like the others mentioned) or if it needs quick attention. Have you already checked with a mechanic or would you rather wait to see if the light turns off on its own?
