Ford is aware of a design defect that causes the vct system to wear out within a short amount of time in brand new Expedition. When the vct system wears out, the vehicle immediately transitions into "limp mode", which causes the vehicle to immediately (unsafely) decelerate to a speed of 15mph (or less on hills), creating dangerous situations, particularly on highways and when towing. We purchased our Expedition in March 2019, brand new. We purchased the vehicle with the heavy duty tow package, which provides towing up to 9,300lbs. Within a few months, the vehicle began making a loud rattle at start up, lasting a few seconds. We diligently serviced the vehicle only at Ford dealerships, who routinely said the rattle was "fine" or "within spec." On 9/1/2020, while towing our airstream trailer (~7,000 lbs) on interstate highway 86 through windsor, NY, the vehicle threw on the "wrench light" and rapidly decelerated from 55mph to 10mph. We were at the bottom of a long incline, in moderately heavy traffic (65mph). There was an insufficient shoulder to stop with our trailer, so we very slowly crept for miles to the nearest exit. The closest Ford dealerships refused to look at it. It was eventually towed to oneonta Ford. Despite knowing of tsb 20-2315 (and its predecessors), Ford claimed that the vehicle was "fine" and likely just suffered a bad oil change. After spending 12 days with our vehicle, they returned it, performing only an oil change. The rattle remained and Ford claimed there was nothing they could do. On 10/9/2020, the very next time we attempted to tow, on county highway 2, the vehicle again, abruptly went from 55 to10mph on a long, slow incline in moderate traffic. We turned around (with the trailer) on a 2 lane road. The vehicle was towed back to Ford, who reluctantly (after weeks) replaced the vct system per tsb 20-2315.

Followed semi into dealer service parking lot. Semi turned left so moved forward to join line of cars into service bay. While coming to stop, semi on left backed up and coming right for me. At my stopping, auto engine shut off turned off engine as was trying to shift to reverse. By time engine turned back on, acknowledged reverse, engaged reverse, responded to accelerator being pushed, gear engaged, the truck was about to hit me as driver did not see me. Luckily driver noticed and slammed on brakes. By this time, vehicle was still trying to move so if truck did not stop, I would have been hit. Auto stop of engine is a dangerous feature. While may work at a traffic light, in a situation requiring quick response, too many steps to turn vehicle on and engage a change of direction. Ford has a feature to turn off manually, but should be allowed to turn off all the time. If vehicle shuts down in emergency situation as this, a person could be killed. This event was viewed by several people and all I could say was could not move as vehicle did not respond quickly enough. Emissions are not more important to people's lives and this feature needs to be removed or allowed to be overridden.
