While driving down the expressway at 70mph my vehicle loss power entirely and stalled. I was nearly hit by the vehicle behind me and forced to pull over to the side of the road. The check engine light came on at the same time and indicated a camshaft position sensor, crankshaft position sensor, and ignition errors. I've owned this vehicle from the day it arrived at the dealership. The problem at fault has been previously identified by Ford in a TSB for the engine wiring harness chaffing on the intake manifold. Owners are not notified through mail on TSB's and this vehicle has been serviced by the dealer since the TSB was issued. I believe this should be a recall condition due to the accident potential this problem creates.
The contact owns a 2013 Ford Focus. While the contact's daughter was driving 70 mph, the driver heard a loud scraping sound from underneath the vehicle. The vehicle was taken to north brothers Ford (33300 Ford rd, westland, mi 48185) where it was diagnosed that the muffler detached from the rest of the vehicle and was dragging on the road. The vehicle was not repaired. The manufacturer was not made aware of the failure and stated that they would not assist because the vehicle was no longer under warranty. The approximate failure mileage was 19,000.
