90s or 80s Sci-Fi movie about a female cyborg / robot

I think you may be looking for Cyborg 2: Glass Shadow.

In the year 2074 the PinWheel corporation creates an 'almost-human' cyborg Casella Reese, aka Cash, designed specifically to charm/seduce her way into a rival manufacturer's headquarters and then self-detonate. Things go awry, when she starts to have feelings for a human Colton Ricks, aka Colt 45, who works for PinWheel as a martial arts instructor. He falls for Cash as well, and with the help of Mercy, they escape. PinWheel Corp. sends Danny Bench, a 'Cyborg Tracker' after both Colt and Cash. Violence ensues.

It was following by a sequel, Cyborg 3: the Recycler

Prepare yourself for the all too deadly future. Cash, the heroine of Cyborg 2, is living safe in the free zone. But not for long. Biomechanical problems are taking down her systems and a visit to a doctor in Silica confirms her worst fears. She is more then a marvel of cyborg technology. She is the first of her kind to become a creator-she is pregnant.

What does not match, as you might guess from that she shows up in the sequel, is that Cash does not die after exiting the facility, although in Cyborg 3, the scene where Evans shows Cash is pregnant does have him holding what looks like a remote control, plugged into her.

Trailer / "Best Parts"

Found by searching for science fiction film facility escape desert cyborg, which turned up 80's (?) sci-fi movie identification, cyborg, desert, isolation, which has an answer referencing Cyborg 3, which led to me looking up what the prequel was.

American Cyborg: Steel Warrior(1993)

After World War III people are sterile and ruled by the artificial intelligences they created in this violent world. The only woman who was able to give life to a fetus has to take it through the dangerous city of Charleston, South Carolina to the port where a ship is on its way to Europe. She is followed by an android assassin through all the dangers, and only one man tries to help her survive and protect her from the killing machine.

This sounds like it could be Nemesis

In the movie, the main character Alex Raine is a cyborg former cop, in the first movie, his ex-lover, Jared is an android. With respect to her death, "It turns out that Jared was fatally wounded in her escape from LA, requiring her memory core to be salvaged from her body." I seem to remember lots of industrial settings and desert.

This sounds like Cherry 2000 (1987)... I vaguely remember this.

In 2017, a successful businessman travels to the ends of the earth to find that the perfect woman is always under his nose. He hires a sexy renegade tracker to find an exact duplicate of his android wife.
