"I think a lot of Knight Rider fans will be surprised to learn that although Hasselhoff and KITT had great on-camera chemistry, off camera their relationship was marked by creative disputes, personal resentment and flat-out jealousy," said Guy Morris, a spokesman for E! Networks. "During the show's run, NBC was able to keep a tight lid on the costars' behind-the-scenes feuding, but True Hollywood Story will show how their conflict propagated an unbearable production atmosphere that continually threatened to tear the show apart."
Included in the revealing one-hour special are interviews with cast and crew members who witnessed firsthand some of the disputes between Hasselhoff and the technologically advanced Pontiac Trans Am known as KITT.
When David landed the role of Michael Knight, KITT complained to me that David was a half-witted punk with less talent than a Chevy coolant system. 
"Meanwhile, KITT was always trying to stilt David's performance by honking during his dialogue or accidentally running over his foot every once in a while during a scene.
"TV and magazine people started asking for interviews and photo shoots with only David, not KITT," said Jeffery Dorn, who produced the Knight Rider episode of True Hollywood Story. "This must've really got KITT's oil boiling, because as they were shooting the season one finale, KITT 'accidentally' activated the emergency ejection system during one of the driving scenes and nearly sent David to the hospital.
"At this point, David and KITT could barely stand to be in the same car together," said Dorn. "KITT was threatening to run David over the next time he wasn't looking and David started carrying around a bag of sugar as his own subtle threat. But when NBC offered to double their salaries for a second season, the two agreed to put aside their personal differences and go back to work."
"Professionally speaking, KITT became about as reliable as a used Fiero," said Grimaldi, recalling how difficult to work with KITT had become by 1985. "KITT would roll in about an hour late - tires almost completely flat, covered with mud and with an engine that would barely idle, obviously having been out all night. Getting stunts out of KITT on those days was almost impossible. It's pretty hard to run a slalom on two wheels when you can barely drive a straight line on all four."
"Most of the crew knew that KITT has started taking a hit of Techron Concentrate before shooting really demanding stunts," said Grimaldi, referring to an over-the-counter fuel-injector cleaning treatment that is typically mixed with fuel to achieve higher performance. "That kind of thing isn't all that uncommon in Hollywood when you're under pressure to nail a fifty-foot jump on the first take, so nobody really thought KITT using the stuff was any big deal. But by mid-way through the fifth season, KITT was using the stuff everyday, regardless of what kind of driving scenes were scheduled. That's when I knew KITT was developing a dependency."
"If we had pressed on with the show, it was only going to be a matter of time until KITT would be found dead on the side of a road somewhere, either having blown its gaskets out or activated its self-destruct mechanism or just having finally run out of gas, you know," said Grimaldi. "They were never going to find a car that could take KITT's place, so NBC decided to just end the show. It was for the best, I think." Wie wahr.
