Patricia Mcpherson's (Bonnie) return to the show after being out the whole second season.
This two hour season opener is split up into two parts for syndication.
Because real-life technology was catching up with the technology shown in the show (cars with built-in voice recordings that remind the driver about doors being unlocked, gas running low etc.), producer Gino Grimaldi felt that the best way to update K.I.T.T. was to have it completely destroyed and for Bonnie to have to put the whole thing back together again but with more futuristic components
Patricia McPherson was almost injured during the filming of this episode. The guy who was carrying her over his shoulder, tripped over a camera cable and they both fell over, with McPherson being knocked nearly unconscious from the fall.
KITT's newly installed features include a Self Analyzing Probe, a three-dimensional Interactive Graphics Plotter (IGP), a Thermo Dynamics System, Electrical Generating Mode (EGM), a Polyphonic Synthesizer and a Passive Laser Restraint System.
