The vehicle stalled when driving on the highway. The vehicle would sometimes cut completely off. The vehicle was taken to the dealer for service, but the dealer could not duplicate the problem. While the dealer was trying to find the problem with the stalling, they found that the brake module lost communication with the computer. The stalling problem continued to occur. Other problems were: The battery light had come on followed by engine stalling, the ebcm was intermittently dropping out therefore the ignition relay was replaced and the liftgate did not open properly.
