The car turned itself off while driving 55 to 60 mph on a highway. Would not turn back on after getting to the side of the road. Very dangerous.

It was diagnosed as the Telecommunication Module, this part malfunctioned causing issues with audio in the vehicle. The audio would at times play normal, at times go completely out losing all sound to turn signals, hazard signals, and safety sensor audios inside the vehicle. It would additionally lose communication between the key fob and the unit causing warnings during driving and non-start issues. With that said, the lose of audio when expecting safety sensor sounds, or sudden audio on complete full volume with the only resolution being to shut the car off is a safety issue. The vehicle had to be pulled over on the travel portion of the highway to resolve the sound issues on multiple occasions. Software updates, radio head change didn-??t matter, until it was diagnosed as the module described above. Occurrences were completely random.

When I started up the vehicle with the key fab button I noticed the cabin air blower came on as normal however when we went to the cockpit we noticed the engine was not running. When we went to start the vehicle (holding break and pressing start button) the dashboard started the Z71 launch sequence and then went to a dashboard as if I was in the normal drive mode however the dashboard was extremely dimly lit as if the backlight was not on and the engine still was not running. After several attempts to start using the brake+start button method we noticed a clicking sound that seemed to be coming from the engine cabin just in front of the passenger cabin however it would never ignite/start the engine. After several attempts to start the engine through the brake+button, we tried to just press the start button, which would sometimes be prompted on the dashboard, and get some feedback from the dashboard through better backlighting and messages I now cannot recall but never ignited the engine. When we tried again with the key fab x2 button (hoping it would either start or "cancel" the current vehicle state), we received no response from the vehicle. When we attempted to shift, it stated the "conditions were not met", which I perceived as the correct response. The vehicle was stuck in this "mode" with the air blower still running and exterior lights still on and it was only a matter of time until the battery ran out. When it ran out later that day (though not completely ded) in rebooted in the same tweener mode. However, when we came the next day with a tow truck and a fully dead battery in the Suburban, the vehicle booted right up as normal. The tow truck driver indicated several new Tahoe drivers experiencing the same issue. To me, this is a software launch issue. While the vehicle was not perceived to be in danger, it left us stranded in what could be a dangerous location. Several episodes as reported by tow truck. Unsure if inspected. No symptoms before problem.
