What owners say about the electrical system
Verbatim from NHTSA complaints, newest first
“TCM component major failure as diagnosed by dealership. Vehicle has inadvertently tried to go into park on multiple occasions when trying to speed up/ overtake. This failure has also caused the transmission to need a complete overhaul.”
“The infotainment screen that includes the rear backup camera stopped working intermittently and then completely. The dealer's service department identified that the APIM, a module involved in operating the screen had failed. The backup camera is a significant and necessary safety feature for such a large vehicle. The dealer ordered the new part and replaced it at significant expense. There was no warning of this issue, and the only symptom was the intermittent delay of the infotainment system turning on upon startup of the vehicle.”
“Engine light stays on along with manual light and charging system service now. Battery, alternator changed out, 3 mechanic repair shops can not find what is wrong. Vehicle bogs down and does not run right when the Manuel light comes one which is about 2 times a week.”
“Ford performed Emission Recall 24E13 on my vehicle. The corporate software update bricked the Powertrain Control Module (PCM), rendering the vehicle completely inoperable 30 miles later. Ford corporate is refusing to repair the damage caused by their mandatory safety campaign, leaving me stranded. The vehicle was towed back to the dealership the recall was performed. They ran a full diagnostics and confirmed the PCM is bricked.”
