New member here and new Ecoboost owner in NE Ohio. Just traded my 2013 Explorer XLT on a 2015 Explorer Sport...it's the vehicle I've always wanted. After reading in different forums about the carbon build up and water pump/engine problems I'm hoping mine is going to be problem free. I bought it with 56k miles on it and come to find out at approx 54k miles the previous owner had it in for repair under warranty for CEL. The dealership ended up replacing a sensor, timing chain and one of the turbos...along with some other miscellaneous items. First thing I did after getting it was change whatever oil was in it to Mobile 1 Annual with Mobile 1 filter. Next item will be an oil catch can......then some other small mods. Hoping to have it for quite a while and to enjoy being a member on her.
