    ... have made the purchase. We had a 2020 Ascent which we liked and after driving the 2021 we wish we had kept the 2020. Dealership has looked at my vehicle a couple of times and said there is not problem with the vehicle, but my wife and I plus my son have all driven this vehicle and have the same complaint, wanders endlessly on the road. My advice, drive one several miles before buying one so you don't make the mistake we made. Read More
