AWD Module tested internally bad when assessed by local dealership. Vehicle was taken in for assessment after a software update recal was completed as vehicle then started stating vehicle had a powertain malfuntion, Pre-collision system was off, Hill.assist was off, Traction control was off, 4WD unavaialble, AWD unavailable. The dealership AND Ford Customer Service states that this was not covered under the warranty as it was not a powertrain malfunction but rather and electrical issue. I researched and found Customer Satisfaction Program 21B19- AWD Module Replacement was filed with the federal safety agency ID Number: 10191184. Which has my vehicle make, model and year stating that there was in fact a known issue. I was never notified of this issue and am now being told my problem is only electrical and not covered under my warranty resulting in me having to pay out of pocket to correct a KNOWN problem that has been documented.

The pre collision assist / warning is not working at all. Someone was cut into my lane in front of me and I was almost hit him so I need to hit the brake in the last second but no warning showed up at all. After that I tried to test if the pre collision warning system is working or not so I tried to force them such as I drove into like almost hit to another object/ car without hitting brake but I never get or see any warning on the screen.I even setting the sensitivity on high! But it never worked at all. I used to drove the car that has the pre collision system so I know how it's work. So I'm sure my car has a problem
