The contact owns a 2011 Ford Fiesta. While driving 60 mph at night, the contact was pulled over by a state trooper who alerted her that the vehicle's headlights were not illuminated. The vehicle was taken to courtesy auto & truck center (103 e hill st, thorp, WI 54771) where it was diagnosed that the battery junction box had corroded all the headlight wiring, which needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and did not assist. The approximate failure mileage was 100,000.
While in motion, my vehicle had an intermittent electrical issue. The service wrench appears, and displays "engine malfunction, seivce now" the engine then derates and runs very rough. With a manual transmission, it is difficult to shift gerars without stalling. Upon turning off and restarting, the engine resets and runs normally. Occurences are random without any warning. This is a safety issue. In one instance my engine nearly stalled in a busy intersection as a result of this issue. Ford has a TSB for the issue (13-11-15) that involves changing the wiring of the car. I believe this should be elevated to recall status so that repairs are covered. Given that it is a design issue that was built in to the vehicle and requires a change to the wiring to fix, Ford should be responsible for the service. I was billed $442. 85 by my dealer to correct this issue.
