 CONT: In Season 2, where Jack Bauer and Sherri Palmer are racing  through LA in the black GMC Denali SUV, Jack has a heart problem and  the SUV goes careening into a nearby ditch. Prior shots showed the  SUV having all four GMC alloy rims. The SUV that was shown actually  going into the ditch had a regular black steel rim on the front  passenger side. In the very next shot (appearing in the following  episode), the front right wheel returned back to a regular GMC alloy  rim.
