Check Engine Light On problems of the 2015 Ford Fusion Hybrid

This car has been in twice for a cam position sensor. The first time the part totally failed and left us on the road side on a very dangerous stretch of hwy 101 and was replaced. 1708 miles later the check engine light came on again. The code was p0340 again. We were told that the issue could not be duplicated through a dealer road test and we were charged $190. 00 for the diagnostics. The first time this issue occurred, we had brought the vehicle in for a safety recall. When we picked the car up, this was the first instance of the failure of this component. This has caused us grave concern. My wife has ms and can't be left on the roadside. We believe this vehicle has the potential to be unsafe, and Ford will not stand behind their repairs as the computer shows the code that would state the issue has happened again, but because the service department could not cause the code to occur a third time, that everything is working well. Again, we believe this is wrong and wish to make the public aware of a very real safety issue. We have contacted the dealer about the issue. Our service adviser is jessica gallegos from mock Ford (should be noted this is not her fault nor I believe mock Ford) and the Ford rep is cortney burke, 866-631-3788 x77756 . We do not know at this time if the issue has been remedied. Only that through a test drive it could not be duplicated. The computer log shows the incidents. Should we just ignore this and hope for the best?.
