The vehicle had approximately 3500 miles when returned to dealership. The primary issue was "running rough." The vehicle was in the repair shop over five weeks. In three incidents picked up the vehicle when it was supposedly fine. Within minutes the cecile stalled and starting to shutter. Warning indicators include engine and transmission system, emission system, stabilitrack stability control system, and antilock braking system. Vehicle unsafe to drive. The 2015 Suburban was newly designed. Repair bulletins were issued. Vehicle recently picked up and still "runs rough." The vehicle handles differently as it shifts from V4 to V8 (fuel economy design) when slowing. This makes the vehicle handling inconsistent depending what mode it is operating and can be unsafe. Other potential safety issues when raining, the rear camera (backup) is not functional. Also, when starting in reverse, there is an extended period the "computer is loading" and their is no input although your backing up. In essence, the rear backup warning system is not functional.
