My car "service engine" light came on as well as a message on the dashboard with the words "safety assist" and "security". I immediately brought the car to the dealer. After 2 days in the shop, they said it was (as posted on the paperwork released to me) "cylinder 3 misfire and cold start rough start. Found cylinder 3 plug fouled out poss from moving vehicle all winter without ever driving vehicle. Replaced #3 spark plug, swapped coil #3 with coil #2 to see if misfire moves to cylinder #2. this way if condition is not resolved, I will know if coil is bad or engine has a mechanical problem. Rfh flashed and ABS flashed" they released the car to me and said it was fixed and safe. Upon driving to work at 5 am, in the dark, I had no exterior lights and could only use my high beams if I held them on. I had no back lights. Cars approached very close to my car and I had no idea why. When I got to work, I had another worker check the back of my car and there were no back lights or brake lights. I called the dealer and left a message and dropped the car off after work. After further review, they have now told me the engine needs to be replaced....on a 2016 car. Ridiculous. Thank you
