This would seem to be specific to your phone and not your wife's phone. I'm having the exact same issue with my 2012 Range Rover Evoque which had paired fine with my iPhone 4S previously. Interestingly, I was able to pair my new iPhone 5 the first time (using the factory default PIN for my car) and had it working on my first drive to work. When I restarted the car to head home that evening it stopped working then and I haven't been able to get it paired again, with the factory default PIN or otherwise.
I've cleared all previous phone & device profiles with no luck. My next move will be to restore the phone to factory defaults via iTunes and and try that.
The fact that I had it working well on the first attempt is perplexing.
