We have three cars so we do not have to drive the Ascent all the time. We purchased in July of '18 and as of today have 11,000 miles on the clock. The 36k / 3 year warrenty is going to be 20k miles shorted because we do not drive a thousand miles a month. Seems unfair. Is there a decent warranty that can be bought? or should we just sell the low mileage Ascent and buy new again?
