I am a new owner of the QX50 Hybrid and although I love my new car I am seriously disappointed in the gas mileage. Wondering if it's just my vehicle or if others are having the same results. I have 1500 miles (I've had it 5 weeks) on the car now and my avg. mileage is 18.8mpg. I would say my driving is split to 70% city and 30%hwy. I wish I hadn't gotten the hybrid... on my lease I priced out the same options on both hybrid and v6 and it was $40 more per month for the hybrid. Based on the window sticker estimates I should be getting 26-28mpg and if that was the case it would more than make up the price difference. A few days ago I brought the vehicle in for them to check if there was something wrong with it because of the low fuel economy and they gave me a qx50 3.5 to drive for 2 days. I GOT THE SAME EXACT MPG!!! That is so wrong!! The hybrid should at least be getting better mpg than the 3.5, don't you think?? I am considering going in and demanding a new car in the 3.5 engine or maybe they should make up the price difference to me?? it's $1560 more for my 39 month lease! Anyone have any advice or similar issues... or on the flip side is anyone driving the Hybrid and actually getting the mileage they should be getting?
