Update for me, the regional rep asked what kind of gas I've putting in the car (I almost said "Aren't you supposed to ask me that if I have a HPFP issue?"), and of course I only use 91 and above at the right stations. So they want to put a bottle of fuel injector cleaner in it because they think its an engine/fuel injector problem. I'm a bit incredulous at this since I have suggested to them that the mechatronics may be the culprit, based on others having the same issues. I'm seriously at a loss at why they seem unwilling to even probe the mechatronics as the problem.
