“We were coming back from a trip with my children and this vehicle was barely 2 weeks old with 0 miles and we were on a highway when all the emergency lights on the dash went off. It was flagging the electrical system, the engine, the brakes. Honestly all the lights possible went off. The vehicle was lagging and it felt force when we pushed on the gas. Our hands were gripping the steering wheel to keep it in lane till we could get off.”
