The check engine light isn’t the problem. Putting tape over it is.

Warnings are annoying by design, and the annoyance is the feature. Covering one removes the discomfort and leaves the thing that caused it running underneath, now with no way of telling you how it is going. People do this with more than cars: muting the notification, not opening the report, avoiding the friend who asks direct questions.

Find the alert you have been silencing and look at what it was pointing at. You do not have to fix it today, and even naming it puts it back in view. Warnings you can see are just information, and the tape is the only part that makes them dangerous.
