2017 Santa Fe Sport 2.4L AWD CEL Flashing

Question by JustAJarhead posted 7 months 2 weeks ago in Hyundai

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.
