Vehicle overheats in hot weather when driving for greater than 30 minutes. It is not the radiator but the transmission which overheats as indicated from the warning light. When this occurs, the vehicle shuts down and becomes inoperable until it is allowed to cool. This leads to the car dying on the middle of the highway or wherever you happen to be. This is a known problem which Jeep needs to address.
