Transmission & drivetrainEngine & cooling

When driving on freeway the vehicle overheated and engine warning light flashed and had to come to stop at side of freeway. The vehicle had lost its coolant from a rear heater hose connection. The car was towed to dealer and the repair comment was that a part was deformed from mis-assembly (or words to that effect) - rear heater core fitting clip distorted causing hose come of the core. This was an early life failure.

Driving down a busy section of highway on I-25 in Colorado, without warning car lost all power and shutoff. Was able to veer off highway to shoulder without getting hit. Car will not restart. This was incredibly unsettling as my family and kids were all in the car on the way home and was a very dangerous situation. For a brand new vehicle to shut off on the highway without warning is unacceptable.
