NHTSA Complaint #11585555 — 2018 HYUNDAI ELANTRA

I was driving about 45 mph when the car just turned off the first time. I was able to put it in neutral and start it back up to get to the side of the road and it died on me again. I was about 30 feet from my destination at this point so I got it where I was going and turned it off. When I turned it back on it was making a terrible knocking/grinding noise. It didn’t have a drop of oil in it (about a thousand miles after my last oil change mind you) so I put oil in it and started it again and the sound quit. I went to drive it and it died before I could accelerate to a decent speed, got it cranked and rolling again and it slowly got up to 40 mph, but the second I started to slow down again it would die. So I had it towed to my mechanic who at first thought it was because the timing chain had a lot of slack in it, assuming it jumped time so he changed that, but it was still dying. He ended up finding the cause to be the exhaust cam sprocket? I’ve never heard of this before but I do know that ever since I bought the car 3 years ago it never felt like it would get up and go whenever I hit the gas. Since I picked it up from being fixed, this thing zoom zooms everywhere now! But it is still using an ungodly amount of oil between oil changes.
