Known issues on the 2004 Express 2500. Seven recalls attach to this year. One covers seat belt buckle latches made brittle enough that they may not hold against the force a crash applies, so the belt cannot restrain the occupant as designed. Another involves a transmission shift cable that can separate, after which the lever position and the indicator no longer agree and the van can travel a direction its driver never selected. A third concerns a fuel filler pipe corroding badly enough to leak while the tank is being filled. Owner complaints number 57, fifteen of them on the service brakes and six each on fuel and steering.
