Unable to answer an incoming call when connected by bluetooth: 1.phone rings through vehicle speakers (normal) 2.after 2 ' 8 seconds the audible, 'you have an incoming call' is heard. (normal) 3.if the call hasn't been answered after several seconds, the second prompt 'to answer a call, push your hands-free calling button' is played. 4.failure: no 'accept | reject' dialog is displayed while the phone continues to ring. Please note: an incoming call cannot be answered by button-press or screen selection until the 'accept | reject' dialog is displayed on screen. This behavior is very intermittent but is more likely after using GPS guidance for an extended period. This appears to be an infotainment system failure that can occur during any driving situation. The vehicle is the 2015 cts-v coupe. This is relevant because this model has the pre cue infotainment system. Other 2015 cts and cts-v four doors have the cue system. I have had this problem from the first month of ownership. Another vehicle owner has the exact same problem. It fails with my iphone 5s and se; it fails with the other owner's android phone.
