So I have been searching the threads to see if I could find out if anyone else is having the same issue as I am. I bought my 2017 with 10k on it. I have put about 5k on it. Well 3 days ago the performance changes on it drastically. I noticed that dropping it into 4th on the highway and I have slow acceleration. I mean I know when I first got it, I could drop it into 4th and it would fly. Now it seems to fall on its face with no power. Day number three, check engine light comes on, rolls in drive way like it has an old Mercedes diesel engine in it.Checked engine oil, of course, not that much consumption. I took it to the dealer and now I am awaiting the verdict on what it is. Anyone else out there have any issue like this? I love the car but man it makes me want to pull my hair out and go steal my 03 Cobra back.
