Continuity: In the beginning of the movie Jeff and his wife were moving to San Diego from Massachusetts. Well, they were driving in their new Jeep (with Massachusetts plates) through Arizona. When Amy comments about how fast Jeff is driving, the camera shot shows the speedometer at 80 mph and the odometer shows the Jeep has only 245miles. That must be a new record from MA to AZ.....

Breakdown mistakes
Factual error: Any auto mechanic will tell you that there are no wires underneath the area where Kurt Russell is looking on a Jeep that will prevent it from starting.
Continuity: When Kurt Russell gets his Jeep running again, after discovering the disconnected wires, the front wheels are pointing to the right. In the very next shot they are pointing to the left.
