Some missed approach procedures contain "(vectors)" as a waypoint in the FMC. Regardsless of whether or not it would be the best mode to engage would LNAV be possible to engage for missed approaches in this cases? If, yes confirm that the aircraft would maintain present hdg/course upon reaching the "(vectors)" waypoint indefinitely?
Your comments are welcome:O
Yup, the vector if coded can be flown in LNAV and is shown as an endless line on the ND and will be flown that way.

I would check the coding and the waypoint...unless it is part of a coded procedure that you already have, there may be issues...
The waypoint is part of a system, it can be high/low, have a min altitude, and/or be a part of an approach/departure.
I have seen this attempted use before, when the waypoints denoted a procedure that had TF and RF legs snaking a path along a mountain range...
the system would vector to the nearest waypoint on the route, but because the route doubled back around a mountain ridge, the system vectored the aircraft through the ridge, as this was the shortest distance between waypoints
(ref the southern approach to CYLW, Kehlowna)
Picking a waypoint and using the vector can be an issue...
