We took our vehicle here 4 weeks ago to have recall work completed, once we received our vehicle back the display screen (radio etc) kept going black and we started getting a 4X4 AWD and DSC error that would cause the vehicle to loose power while driving. My husband took the vehicle back down to Co's almost 2 weeks ago, we paid over $1700 for a new Audio Head (that controls the display screen), they finally delivered it to us today (4 days after we drove 5 hours to Colorado to pick it up and it wasn't ready) and 2 hours later the vehicle had the same fault 4 times on my drive home, but now it is completely shutting down the engine (so very unsafe in the snow and low visibility). I called the dealership tonight and was told "it wasn't doing that while they had it, so they couldn't diagnose it". I was also told I would need to pay for a tow to get it there, since it is not drivable now. So here I sit, in the Wyoming winter without a drivable vehicle!
