I believe the engine could possibly be failing. My engine light will come on & flash, when it does this it is slowing down at speed ranges of 60 mph. Another thing, the GDi engine that is in this vehicle burns oil EXTREMELY fast. It is quite aggravating having to constantly get oil changes every 2-4 weeks & have only driven 0-1500 miles. This is not normal. The engine has this crackling noise as if it’s chopping metal.
