The check engine light can come on for many, many reasons - the same as it could be in pretty much any car brand out there. But, there is no way we can tell you what is wrong with the info you provided. Essentially, you're asking us to guess from the hundreds of possibilities.
From what you've written, your best bet is to take it to a mechanic that can scan and/or fix whatever the problem is.

Code reader
Do you own a code reader? If no I would at least buy an IcarSoft. Like Eric said it is extremely expensive to own these SUV’s (most of the time worth it 😂
but without the ability to do some of the work and at least decent amount of troubleshooting we’ll open up your wallet and checkbook $$$$$.
This site is full of knowledgeable people ready to help but honestly everybody is really busy and you need to come up to speed some with a code reader. thanks Bill
