I’ve been getting exceptionally bad gas mileage with my 2016 Jeep Renegade. It’s the 70th anniversary edition, a 4-cylinder engine w/ automatic transmission and 4WD. The sticker said 29 highway, 21 city, 24 mixed use. I’ve consistently gotten around 16mpg for the first 12,000 miles, including at lea…

post #17 says the dealer got 32mpg on their test? what was the distance traveled? you also say you use the trip computer and come nowhere near that number? i play with my trip computer and can reset it while i am driving on the highway and i get 33mpg approx initially. than after 5-10 miles it drop…

I saw the 32.7 MPG for their “trip” when I retook possession of the car, and I’m sure that number will be used in the dispute with Fiat Chrysler. Unfortunately, I have NEVER been able to achieve that kind of fuel economy with this car. I wish I could, because then we wouldn’t be having this dialogue…

One point that I was getting at in a not very clear manner is that it’s entirely possible to have a hard fault with no diagnostic codes being set. Logic says this should not happen, but… I had earlier mentioned the possibility of a faulty engine coolant temperature sensor. Many years ago my Mercury…

try a reset on the hwy? at least we all we know whether the jeep can hit 30+ mpg at least initially.

Yes, I know how to do that (reset), and have optimistically done it hoping that I would actually be getting the fuel economy that I’m supposed to be getting. Unfortunately, testing sensors is beyond me, but perhaps I can find someone to do that…

As somebody else said, ask to have the car tested with you in it, see how they got 32 mpg. Could have been driving 20 mpg on a back road for all you know.

whew, its like pulling hens teeth. you have done the reset on the hwy? and you got what initially? i expect you to say you got 33mpg initially, and than drove home. and it said 25mpg avg and than drove to work the next day and now the average is 15mpg? my former car listed fuel used and miles d…

[image] KevinGreenstein: I’m averaging 16 MPG in total, including all fuel purchases and miles. I’ve been complaining about the fuel economy from the start. This tells me the 16 MPG figure is a long term average. Would an engine that is burning that much excessive fuel show too-high unburned…

The fact that the dealer got 32 MPG rules out, to me at least, a mechanical problem, unless the dealer were cheating. As others have asked, could the OP check the mileage driving at a fixed speed, say 50 MPH, on an open highway? reset the computer (as you are driving), drive for 10 miles under the …

i guess it does not matter what your computer says when you reset it on the hwy. 1 day later or maybe 4 or maybe 2 weeks later it says the average is 16mpg. i am just curious what it says initially. which we may never know
