Check Engine Light

Is anyone else having this problem...My check engine light keeps coming on. I have been fighting this thing for a while now. The car runs fine, but the remote start won't work when it is on. They can't seem to find out why it keeps coming on. Getting to be frustrating. I have a 2015 with only 8K miles on it. Every time I take it in, they do give me another Lincoln to drive, but I want to drive my own and I want to be able to start it remotely too.

Check Engine Light Going On

I do have the same problem sent back to the dealer, says gasoline problem. However changed gas station fueled with Premium and the problem still persists.
My bet is a fouled up oxygen sensor, upstream of the cats...ask them to put a sniffer in the exhaust, bet it be running rich!
Try an Italian tune-up - Put premium in the MKC and drive it hard a bit to clean it out. My Cadillac CTS which was also direct injected use to load-up a bit causing a rough idle. I would run the CTS hard up to 3rd gear and watch the black smoke pour out the exhaust and the roughness went away. As stated above, an oxygen sensor may fouled and a hard run may clean it up.
