NHTSA Complaint #11445497 — 2016 HYUNDAI ELANTRA

My car suddenly lost power and would not accelerate over 20 mph. It gave no warning whatsoever. No check engine light no dash lights at all. It seemed as if it was in some type of protection mode. I took it to the dealer and was told it was my catalytic converter. They replaced the manifold catalytic converter and sent me on my way. Within 15 minutes the check engine light was on and has been on ever since. The back of my car is covered in soot and my car uses about 4 quarts of oil per 2 weeks. My car was NOT like this before. I received a letter about a recall and when I took it to the dealer I was brushed off like it didn't apply to my car. My car was doing the EXACT thing that the recall letter stated. I have kept my car maintenance up and fully feel this is a mechanical default.
