Cue (cadillac user experience) system not responsive in a 3 year old car with 92,000miles.although the internet is full of complaints, cadillac would not assume full responsibility to replace part. i was offered a discount (about 20% off) to replace this essential electrical component that should never fail. "the first of its kind technology" that "should serve as a benchmark for the automotive industry" is a complete failure that make the car not usable. the cue system should be a recalled and replaced by cadillac as it impacts essentials such as air conditioning, vehicle setting applications, backup camera, bluetooth, navigation etc. the gm executive office made it sound that is consumable and is the owner's problem.
