My car's check engine light came on. Should I panic?
The check engine light just turned on in my 2016 Toyota Camry. The car drives fine, no weird noises, no smoke, nothing. Should I rush to the mechanic or can I wait a few days? I'm scared it's something expensive.

Take a deep breath — a check engine light does NOT mean pull over immediately. If your car is driving normally with no strange sounds, smells, or performance issues, you can safely drive it for a few days. But don't ignore it for weeks.
Here's what to do right now. Most auto parts stores like AutoZone or O'Reilly will read your check engine code for FREE. Just drive in, they plug in a scanner, and tell you the code in 5 minutes. Write it down.
Once you have the code, look it up on Google or Reddit. Common codes like P0420 (catalytic converter) or P0171 (lean fuel mixture) sound scary but aren't always emergencies. A loose gas cap — seriously — triggers the light about 25% of the time. Try tightening your gas cap first. Drive for a few days and see if the light turns off.
If the light is flashing (not steady), that's different — that means stop driving immediately. A steady light just means "get it checked soon." Most fixes are $100-300, not thousands. Get the code read, then decide.
