my 2024 yukon denali has 1700 miles. The range estimate seems off by quite a bit. when full with 24 gallons of fuel and an average MPG of 20, the range says 430 miles. mY older 2021 yukon which I traded in , always showed around 480 miles range when full 24 gallons and approx, 20 MPG. The dealer says I need to drive several thousand mile and it will fix this problem. I doubt that is correct. Thoughts?
