Girl that unwillingly becomes a cyborg during a rainy night

I watched it once on TV. Not sure if it was a movie, or a TV show/series.

• Some guy was trying to capture some bad guys (how much I can remember) and his girlfriend or maybe his female police partner (not sure – maybe both), got into a car accident, or was otherwise wounded by those bad guys.
  She wound up in "hospital", where they turned her into a cyborg!
  She woke up during the operation and escaped through the hallways to the hospital roof, where it is shown to be night-time and raining.
  The guy shows up on the rooftop as well, and the two start arguing in the rain, where she says something like "I’m a monster", or "I’m a freak" and shows her robotic hand! It’s similar to a scene from Terminator 2: Judgment Day – with a robotic arm, half in skin, half machine, robotic fingers wiggling in the rain, with rain drops bouncing off of them.

• At the end of movie, when they beat those bad guys… they are in an apartment, where the guy sits on a couch, and she sits on his lap like a stripper and begins to "vibrate" – the camera zooms out and shows the building from the street, and there is earthquake like.

• The girl wasn’t blonde… her hair was dark brown or possibly black.

• They were a younger couple.

• I think it’s from the ’90s.

• It’s in color.

• Language is English.

I can say that it’s not:

• The Demolitionist
• Robo Chic
• Steel and Lace
• Eve Of Destruction
• The Nemesis series
