OMG!
Turns out there's some type of microswitch built into the hydraulic fluid pump mechanism that tells the car when the top is fully closed. This switch is acting up, and it apparently can't be replaced. The ENTIRE hydraulic pump assembly has to be replaced as a single unit to the tune of $3,500 in parts, plus some insane amount of labor time yet to be determined. Warranty is covering the repairs 100%, but this is virgin territory for the dealership. The technicians have never worked on a 370Z roadster top before. YIKES
