2015 4x4 check engine light plus

Hoping someone can help. Have a 2015 4x4 V6 automatic with 96,000 mi. Yesterday my cruise control quit working, check engine light came on as well as the traction control off light. Still runs perfectly but if I accelerate even a little over normal the transmission shifts hard. I can also feel it downshift in town which I could never feel before. Any help would be appreciated. Thanks

No way to know till you scan for codes.

 

Thanks gentlemen

 

The cruise control not working and traction control not working is basically a safety feature and automatically happens when you get a check engine light.. so when you fix what ever issue has set a code everything should go back to normal
