We purchased a 2016 Fusion Hybrid Titanium about a month ago. Since then, we've had a couple of seemingly random front "Collision" warnings and several odd Cross Traffic warnings when backing up. No faults have been reported. We're at about 1,600 total miles and these faults have occurred 2-3 times.
In the case of the front collision warning, we've been driving twice on open suburban roads, no traffic. The red lights flash for a few seconds and that's all. For the rear Cross Traffic warnings, we've been backing up and the warnings have gone off with no cars in sight, let alone anything approaching us from the side.
It's particularly noticeable as I also have a 2015 F-150 with the rear Cross Traffic system and have found the system to be extremely reliable. Never noticed any kind of phantom warnings.
Took it into the dealer and they indicated there were no faults or codes, therefore there was nothing they could see to "fix." I'm in IT support, and I totally understand transient faults and how hard they are to diagnose or fix ... so no hard feelings ... at this point!!
I am curious if anyone knows if there is any kind of either self test or diagnostic test that the dealer can do to further isolate these kinds of issues?
Other than that ... we love our hybrid!!
