While driving down the interstate the vehicle lost power without warning and gave a command to ‘press start to resume’ tried to do that but nothing happened. Eventually we were able to get over to the shoulder of the interstate which was super busy in Atlanta. Once we stopped, we shut off the vehicle and it started back up, and we proceeded to get back on the interstate, when the same thing happened. We stopped again, waiting a few minutes and were able to get back on the interstate and complete out trip without any issues. 3 days later while driving on the interstate again, the vehicle had a weird winding noise coming from it. Once I was able to get off the instate the engine was knocking very loudly and had no power. Got the vehicle to our home and had it towed to the dealership the next day. Dealership gave the diagnoses that a new engine, radiator and engine coolant lines needed to be replaced. The vehicle had 2,248 miles on it and was purchase 2.5 weeks prior. No eta on when we will have a new engine and our vehicle back.
