I have a 2024 Telluride S. with 6000 miles on it. Past 2 months when I fill tank it will show between 390-410 miles to empty. I’ll drive 15 miles and it will go down 40 miles. I’ll drive half mile on street doing 35 and it will go down 12 miles. Is this normal. After driving 100 miles it seems to be ok but when I first got car never did this. Dealer said they can’t find anything wrong.
