The car doesn't seem to drive differently when this happens and once I turn car off for a long while they'll be off before I start car again. After driving for awhile like 40 miles they will go on 1st abs than tc and then 4 wheel drive icon

i have two issues that might cause this situation, first you may be experienceing the onset of an a.b.s. or t/c problem. if everytime you drive and around the same miles(40 miles) pass when the engine light appears good chance the abs pump can be defective. The second and least extensive/expensive option is check and replace the fuses to all 3 systems sometimes a fuse is in the process of blowing or defective or even loose and not properly seated good luck

Don't be worried that because several warning lights are on that there are several problems. Many sensors are shared between the engine and transmission control, and the traction control and anti lock brake circuit. One sensor failure can cause several systems to fail, or appear to fail. A scan tool is needed to retrieve these codes in your car, we would be just guessing at what would be wrong without knowing the actual codes stored in the computer of your car. Not sure how far back their information goes but Hyundai as a car manufacturer put a lot of free technical information and workshop manuals on line for Hyundai owners. Check out lots of great information.
