My wife has a 2007 Sonata. She took it to get the oil changed today. drove home with no incident but when she starts the car back up, the check engine and oil pressure lights are on.

I checked the oil level, looked good. No oil dripping off the engine anywhere that I could see. I checked the air filter housing and it's well seated.

Oil pressure lights goes off if engine is revved above idle.

Any ideas??

Which engine is this, I4 or V6? Where was the oil change done and what brand of oil filter was used? If it is the 4 cylinder engine and a non-Hyundai filter was used I would suspect a filter problem that is causing low oil pressure at idle. That's not to say that all aftermarket oil filters are no good but I've heard quite a few stories of people having problems that were solved with the filter being replaced by an OEM one.

Since the check engine light is on I would have the code read to see what it relates to. If the oil filter is non-OEM try changing it to a Hyundai filter to see if that takes care of the problem. You don't have to dump the new oil but you may have to top it up to replace the oil that will be in the filter that is removed.
