75 mph on freeway. Hard jarring sound, followed by Kia shutting down.

What is your question?

Sounded and felt like someone slammed into the rear of the Kia. While I'm traveling at 75mph. Traction control light came on. And it quit running. Coasted to side. Let it sit for 10-15 mins. Started it up and drive it at low rate of speed to next town.

What makes this problem better or worse?
