Just took a trip from WV to Chicago and got your 24.0 mpg with a 25 mph head wind and running at 70 mph cut back to 65 and upgraded to 89 octane gas and got back p to 32 mph
I have 6,000 on miles on mine and average 24 mpg on the highway at an average speed around 80. (Speed limit is at least 70 and traffic flows 10-30mph over). There are a lot of people who will try to disqualify your statement but I think it is absolutely ridiculous that a 1.6L Turbo engine (with a hybrid battery!) doesn’t get AT LEAST 30 mpg on a regular interstate. And it’s not an SUV, it’s a midsize crossover, to the people who keep calling it an SUV trying to justify its poor gas mileage. I have a 2017 base Honda CRV that averages 30mpg on the interstate. It’s at least a 2L 4 cylinder. Bigger engine, no turbo, no hybrid battery, gets much better gas mileage, it’s ridiculous. For what it’s worth, I easily got 40-45 mpg in my 2021 sonata hybrid (it was advertised as 48/51) before trading it in for the Tucson. My Tucson gets no where near it’s advertised 38mpg city/highway. I completely regret buying it. Shoulda just got a gently used ICE CRV. Would’ve saved a bunch of money and actually get good gas mileage.

I'm sorry to read of your struggles... But also sigh.
 
I don't know how to even have a conversation if someone thinks the Tucson Hybrid will get much better than 25mpg going 80 on the highway. Further a very false assumption that a larger engine automatically gets worse gas mileage than a smaller one. Not at all how it works there are facts that back that up. Just a sampling, a smaller engine may be working harder at higher speeds, when where it gets it's best mileage is at low speeds. There's more to it.

Further holes in the post, that Honda CRV weighs somewhere around 400 lbs. less, and comparing a non Hybrid to a Hybrid has pitfalls. Just a little research will show Hybrids are more susceptible to lower mpg in Winter, and when not able to use the battery for longer periods.
Since plenty of people generally do get good mileage its it is either how you drive or a defect in the car.

I do think SUV is overkill, It's a crossover still quite different from a sedan.

Yours is a sad story indeed, sir. Honestly, with the way you drive, the resulting mileage you're "enjoying," what you were expecting, and how you're feeling now, I'd trade it in on something else. There are plenty of vehicles out there that will get the kind of mileage you're looking for. Bottom line, it's your money and your decision. You ought to be thrilled with whatever car you're paying for, after all, that makes paying for it each month worthwhile. If that's not the case, it's a very easy matter to trade it off within the next 24 hours. I've done it dozens of times. Yeah, ya lose a couple nickels. So what. We've lost them before, and we'll lose them again in the future, it can't be avoided. At least you can be thrilled with the car in your driveway again, and not regret buying it or continuing to pay for it.

Funny the Sonata HEV SEL Con. I traded in got an average of 57 mpg around town and 55 on the highway at 65 to 70 mph and dropped off to 50 in winter. but you are trying to compare apples to oranges The Tucson HEV limited I drive weighs 4000 pounds and is not very aerodynamic and yes at 80 I got crapy gas milage. but that was my fault no need to keep up with traffic they will go around you and the drive is less stressful and I always use HDA. Love it!!
 
I'd like to address this statement. Much of what you said was spot on except the statement I quoted above. Though this is true in concept, there's another (and much greater) force at play here. Fuel doesn't vaporize nearly as quickly or as thoroughly at colder temps as it should. This far outweighs any benefits of a cooler denser charge. It has a HUGE effect on gas mileage and unfortunately on hybrid vehicles. According to the department of energy's website, your not just reading some random opinion here. You can read their brief report on this subject here: CLICKY

I'll paraphrase some of it here:
"Cold weather and winter driving conditions can significantly reduce fuel economy. Fuel economy tests show that in city driving, a conventional gasoline car's gas mileage can drop as much as 24% for short (3- to 4-mile) trips at 20°F than it would be at 77°F. It .

Cold weather effects can vary by vehicle model. However, expect conventional gasoline vehicles to suffer (up to) 20% fuel economy loss in city driving and (up to) 33% loss on short trips.

The effect on hybrids is typically greater - with fuel economy dropping (up to) 34% under these conditions. For hybrids, fuel economy typically decreases (up to) 40% in city driving and (up to) 45% on short trips.

For electric vehicles (EVs), fuel economy can drop roughly 39% in mixed city and highway driving, and range can drop by 41%. About two-thirds of the extra energy consumed is used to heat the cabin."

Bottom line: all cars end up with a net loss in gas mileage as temps drop, with PHEVs and hybrids suffering the most (in that order).
I gett better MPG in winter (admittedly Florida winter) for the last 10 years (first in a Sonata hybrid and now in a Tucson hybrid). Only around 2 to 3 MPG better than I get in Florida summers where I get right around sticker MPG at 37.
 
I got a brand new on Jan 2023 , between 20 to 4000 miles , Avg was 25 and winter weather apparently did not help. Now it is getting better, weather is improving and maybe the engineer got settled Avg 35.
Hmmmm...mine has got sticker mileage from the get go. Now, at 10K miles and 18 months old it is still doing the same. I can only assume that location and driving habits are factors in MPG differences.
 
I can't idle and get that mileage, in fact, less than I get at my usual 22.5, more like 18 or 19 mpg, just idling. Listen, I don't know what you're doing, I don't drive like a maniac, but tire of folks giving me these outrageous mileage comments on their 2.5 ICE engines.
You get zero MPG when you idle. If you warm up your car in the morning or don't use the stop and go, it will eat into that top mileage.

You are right. Again for the same reason I gave. Anything OUTSIDE of that perfect temperature results in using more gas. That goes for higher temps as well. Mileage is best around 65 degrees or so. Go above or below, mileage drops. However, due to issues with gasoline atomization, COLD has a much greater effect. Florida winters are perfect for getting big mileage.

Well, they're not going to save any money with a CRV, but they may be happier if it works better with aggressive driving.

My astro with its 4.3 v6 would get 18mpg if lucky. With the hot 350 in her, I was seeing well over 30 MPG (highway) for there is no replacement for displacement.Thats IF I kept my foot out of it, and honestly it was not often I kept my foot out of it, but had to go to Chicago from TN once in it, and the gas gauge was broken, so I did the miles to gallons with it, and every time I stopped, and heck my mouth was always hitting the floor with what I was getting with it on the highway with a 700r4 tranny in it with a torque locker at 1:1 in a brick on wheels.

I truly feel they need to make something that has the GRUNT to overcome headwinds, or highways speeds of 70+ (since there is a ton of over 65 near me), but that power needed at those speeds that the engine can say "gimmie more" for these weak motors cannot handle it, need much more power at lower rpm so that if doing 70, at 2K, its nothing for that motor to keep that and be fuel efficiant, for thats what happened to my van taking the little 4.3 out and dumping in that hot chipped v8. Id love to dump some big ass V8 under the hood of my Tucson, but have some other things in the works, so keep an eye out for my thread coming soon!

 
Just a thought:
As various folks post about mileage on this forum, we find ourselves at odds as some pronounce doom on the Tucson and bemoan it's lousy mileage. Others who enjoy stellar mileage disagree and proclaim the praises of this amazing machine. Here we are on these pages: some hating and some loving the mileage they get with their Tucsons, and perhaps mirroring the way we feel... to include the Tucson in general. We try to sort out WHY there are such differences and find ourselves disagreeing, sometimes strongly, with each others opinions.

But for what it's worth, I just wanted to make a couple observations.
First, it's likely not the car. Modern vehicles are made with meticulous accuracy, especially concerning the WAY the engine runs. This stuff is carefully monitored because it's mandated by government regulations and arguably could land a manufacturer in court. Remember Volkswagen's dilemma when they tried to circumvent emissions regulations a few years ago? So, it's NOT THE CAR: I made my case. It's much more likely that it's indeed the driver and/or driving conditions. Feel free to disagree, but don't shoot me. I believe this to be fact, or I would n't say it.

Second, though we feel we must disagree, typically I think we do so admirably. I've seen great forums lose multitudes of posters because they didn't. I can't speak for all, but I know I've edited many posts here that I felt were harsh... to read a little more respectfully. I like what one fella said, that though we disagree, we can still do so agreeably. And to that end, I'd like to commend so many who've posted here for their obvious restraint in this matter. A forum is best judged by both the number of issues it gets right, and the way it's members treat each other. Though I'm kinda new around here, I'm already seeing that this forum is indeed worthy of all the time I spend reading and contributing here.
 
I think there's enough evidence here for people to stop generalizing that the hybrids can't get advertised mileage, class action lawsuit, etc... Plenty of us can meet or exceed the advertised economy ratings as this thread (and others) have proven.

Unfortunately some people don't want to hear about the variables affecting fuel economy in a hybrid crossover (roof rack, speed, temperature, battery break in period, etc...), because of "x" car they previously owned wasn't affected by those variables. I think that's where the real issue is.
 
Another real life scenario to add to our store of anecdotal material. Today, drove from Santa Fe NM to Shamrock TX. Mostly flat highway, but some hills to get over in NM. Fully loaded car with luggage and personal stuff... AND ... towing the smallest available U-Haul trailer (4x8) about half loaded... so nowhere near the maximum towing limits as published by Hyundai ( I would not do that to my new Tucson). the trailer is shorter than the car itself, so no extra wind resistance, though there was some serious wind along the way. Maintained speeds from 65-75 depending on location; there were lots of opportunities to set the cruise control and settle down between a couple of semi trucks for stretches at a time. Average mileage over 400 miles was 27.2. Frankly, I was pretty pleased with that.
But is the Tucson you drove for this trip a Hybrid year 2022 or 2023. You definitely didn’t clarify.
