I have a 2016 Mustang ecoboost, it has 28000 miles and is totally stock no performance mods. Middle of December the check engine light came on. Took it to a ford house here but the wouldn't look at it until New years eve. I parked it and on January 31st I went to Auto Zone and they checked the code and said cylinder one was misfiring and it needed a coil pack. Went to a different ford dealer, they confirmed the misfire but on further investigation found that cylinder one has a crack in it. The powertrain warranty is covering the rebuild. I don't know what I am going to do with the car. The last three ford products I have bought new all had catastrophic failures, over heated engine melted the spark plugs and studs into the block, transmission failure that left me sitting in the middle of LBJ in Dallas at 4:30pm and a week day afternoon, and now this. May trade it for a different brand.
