We own a Ford F-150 3. 5 l ecoboost v-6 king ranch pickup truck. Truck was purchased in 2014 new. Have serious concerns as the vehicle has so many current issues. From day one of purchase and while still in the dealership parking lot, upon start up there was a very loud clattering sound. Sales rep said it was because it was cold and it had been sitting. Purchased vehicle, had problems immediately with dangerous lag in acceleration (which we still do), an average of 12 mpg if we were lucky and very serious engine misfires with major decrease in power accompanied by sputtering whole vehicle shuddering while trying to merge on the highway or with hard acceleration. Very dangerous, especially if in the fast lane, which we were. We started to limp over several lanes of traffic to the shoulder and the truck regained power. Many misfires like this, all explained to the Ford service tech and verified on the trucks computer. So many in fact it was necessary to replace all spark plugs at less than 57k miles. We just picked our truck up today, Feb 18th, 2020, after it was in the shop again, this time for 12 days, to fix this misfire problem again and numerous other issues with the front hubs staying locked in 4 wd while in 2 wheel drive and switching in and out, timing chain replaced, and the ecoboost turbo tubes replaced as they were cracked, iwe replaced, and left front actuator. Also about 3 weeks ago it had transfer case motor replaced as well as numerous switches, all which did not correct the problems. My husband and I decided to take it on the highway to see if the lag misfire problem was fixed. When he hit the gas there was a screechy sound from the top of the engine, power seriously decreased once again on the highway and the check engine light was back on. I sent an email to Ford and auffenberg Ford in ref to these continuing problems.
