Cruise Control problems of the 2014 Hyundai Santa Fe

The electrical prompts on the face of the steering wheel begin to malfunction. First the volume control stopped, next the hands mobile phone controls. Then the cruise control functions and the menu for user settings stopped as well as airbags. When turning calls are dropped , all functions are inoperable whether car is in motion or stationary.

While driving on the interstate, I noticed a rattling/knocking noise coming from the front of the vehicle, under the hood. The noise kept getting louder, specifically as the vehicle accelerated. I noticed that the rpms would increase, with no increase in speed & even a decrease in speed. During this time the car was using cruise control at approximately 70 mph. As I noticed the knocking noise getting louder, I tapped the brakes & the vehicle's speed dramatically decreased to approximately 40 mph. I tried to speed the vehicle up & the rpms increased significantly, while the vehicle speed did not. I then put my flashers on to signal there was an issue with the vehicle & the check engine light came on, along with other service lights on the dashboard. The vehicle's steering capacity was tight & the ride became extremely bumpy as the speed decreased. After abruptly stopping on the shoulder of the interstate, the vehicle started to smell like something was burning. I could smell this in the cabin of the vehicle & the noticed there was smoke coming from the hood of the car. The engine shut off, but then began to try & turn on, with the lights starting & the start up musical sound playing. It would turn on & off 3 - 4 times, so I then removed the key from the vehicle, stepped out & backed away. The smoke, thankfully, seemed to dissipate after 20 minutes. Fire & police arrived on the scene & did not find any fire, but did smell the burning smell I noticed in the cabin of the vehicle. Unfortunately, we never could get the vehicle's engine to crank again & ended up having it towed back to our local Hyundai dealership.
