Electronics for hands free stopped working. This part was already replaced once. When backing up, the whole truck shut down. I restarted, it said to roll drivers side window down and up. Truck started up again. Few days later… returning from trip, lost power, windshield wipers came on, electronics in truck started blinking. Pulled over, rolled driver’s side window up and down. started back on road. This has happened numerous times. Whenever I gave it extra gas, asking for power to pass, same thing mentioned above happened. Very stressful! Next day, hit a hole, truck totally shut down again. Husband was able to safely coast off road, however, if he had been pulling out at a major intersection, this could have been bad. Warning light that comes with shutdown says ‘stabltrack issue’. I have not seen our dealer service department yet, but plan to very soon. VERY unsafe… and I love this truck!!!!
