Consumer Description

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.
