Blinking Check engine light and traction control light on at the same time?

Hello, the initial activation seems normal, but the blinking engine light and traction control light seem to indicate a possible engine misfire that could be due to some water intrusion somewhere. It's important to make sure anything under the hood of the Yukon is completely free of water or moisture. Hands on testing further may be needed.
