Def issues, first was not feeding def, ford regen'd the system, problem fixed. 2 months later, same issue, now def controller code fault. no covered under warranty.
Exhaust gas temperature sensors fail repeatedly. they have been replaced multiple times. reductant heater a control performance has now failed as well (all part of the diesel emissions disaster). aside from constant breakdowns due to emission related items the truck has shutoff abruptly when it encounters any of these problems while driving. vehicle has shut itself down at highway speeds due to these issues. vehicle said pull over and within 10 seconds it shut down on the freeway endangering the lives of my family and others on the road. as far as when this has happened it has been multiple times. it has been in the shop on 3 different occasions to replace the same sensors and now other components of the diesel emissions package are failing as well.
Death wobble. this has been going on for several years and is becoming increasingly dangerous. we have replaced tires, shocks, steering dampener and track bar. if we hit a bump in the road at highway speeds while in a curve the death wobble is so severe it is lucky that i have not lost control. but the only way to stop it is to stop the truck - on the highway in traffic. i have nearly been killed with people barely able to avoid hitting me. it seems to be a known issue that is, as yet, unacknowledged. commonly attributed to the 'faulty parts' that do not fix the issue for more than a very short time. take it to the dealer and they pretend to have never heard of it before as thousands of others have stated in complaints across the internet. it has become even more severe and will happen even when driving at highway speed without the steering in a curve. the issue first began at about 90,000 miles. typically at 60-65 miles per hour. today it was at 60 mph, 30-40 mph repeatedly.
