After the Local Hyundai Dealer Changed my Oil and Flashed the ECM with Update 19-01-002 my vehicle bucks, stutters and now has a flashing CEL light.

What are possible causes for this problem and does the vehicle need to be towed to the Hyundai Dealer?

The 2017 Santa Fe Sport has 8800 miles on it.

It has had no other problems

All maintenance inspections passed on 04/03/2019

A tire rotation and oil change were done on 04/03/2019 along with ECM Update 19-01-002.

Look,

 

I will recommend you to immediately.. stop your car and take it to the garage.

 

A Flashing ECL light is never a good sign and can most probably due to your Engine misfiring. Should it happen in a new car? NO.. can it happen? well.. it just happened.

 

If you keep on driving your car like this, it will only damage your engine further. Please don't drive it, get towed to the dealership
