I purchased a 2022 Hyundai Tucson Hybrid a couple of weeks ago and I'm having major issues with the mpg that I have been getting. I have drove the car using cruise control with the majority of the time being driven on the highway. I am getting around 30mpg and have tried both eco, smart, and sport modes and all have been horrible. Right now, I'm waiting for Hyundai to contact me (I can't believe it's going to take 7-10 days to speak to a case manager) and I have it parked with 800 miles (in case they can't fix it and need to exchange vehicles). My dealership says they can't do anything without an error code showing up. Has anybody else had this issue? The only odd thing that happened (out of the ordinary) was I went to a drive-in and couldn't figure how to turn off the running lights when parked (figured out later you had to put on the emergency brake for the lights to be completely off). I kept the car electrical system on (to listen to the radio) and it did die and I had to use the emergency jump button on the left side of the dash. Could that have caused an issue? I'm very frustrated since getting 38 mpg was the main reason I purchased this car.

Hyundai and SSangyong has overstated its economy figure by as much as eight percent. This exaggeration is expected to cause a huge outflow of money from Hyundai and SSangyong.

The companies will be fined on the basis of their goodwill in the market. The Hyundai is expected to be penalized for approximately a billion while the SSangyong will face small punishment of approx 200 million.

The reason of huge fine to Hyundai is because it has been a culprit for second time. The 2012 scandal of American subsidiary has also been part of fuel economy issue. The reason many believe, behind the misinterpretation, is that the fuel economy has direct relation to sales increase.
Lets try to stay on topic and not take facts about Hyundai's history as some kind of personal attack on individuals here, that's jut silly.

Hyundai has been caught repeatedly lying about fuel economy of their vehicles, and browsing fuelly you can see that Hyundais generally underperform their self-rated fuel economy. This whataboutism on emissions not only has nothing to do with fuel economy, but doesn't invalidate the fact that Hyundai's fuel economy numbers should not be trusted and need to be crowdsourced.

That's why I think I was the first person here to recommend people keep their own records on Fuelly. That was in no way malicious, its not the same as slapping your child, its just common sense from someone that is completely brand agnostic, having owned a wide variety of makes but being familiar with Hyundai's history. Why am I still interested in Hyundai if I doubt their truthfulness on fuel economy? For the same reason I'm still interested in men even though its the most rare of unicorns to find a man that doesn't make his own exaggerations to make himself appear better than he is! ;)

So far the crowdsourced numbers from fuelly are:
Based on data from 7 vehicles, 44 fuel-ups and 13,232 miles of driving, the 2022 Hyundai Tucson gets a combined Avg MPG of 32.38 with a 0.98 MPG margin of error.
So if you're getting 32mpg, it doesn't mean anything is broken, especially if most of your mileage is on the highway.

Ha! Your post made me smile and chuckle at your wit and made me nod in approval at understanding your points. I was up at the dealership less than a week after purchasing the vehicle thinking something was wrong with the vehicle because of the poor (understatement) mpg that I was getting and had no idea that their 38mpg would equate to 29-30 going 75 mph. Last night taught me that you can get close if you 1) drive 60 mph 2)don't want to use cruise control and have to spend your time trying concentrate on the contours of the road and try to get the car to go into EV mode. I don't think I would be alone in not expecting 38 mpg going 75, but FFS... 9 MPG is a bit unexpected and I thought maybe 34,but that's not going to happen.

I also agree on there being a big moral difference between fudging on emissions and fudging on mpg numbers. I read somewhere that 79% of people consider fuel economy to be their number one factor when buying a car... I know that was the case with me (as well as comfort, safety features and storage following closely behind). True, destroying the Earth with CO2 emissions is bad, but as a business model... Lying to people who purchase your product should not be tolerated. And I blame the salesman as well. He knew my intentions of roadtrips and didn't say anything.

I wish they would have a uniform way of measuring fuel economy and maybe not consider 60mph highway speed (that will just get you rear-ended and have semis pass you).

Thanks again for the post and I'm glad that I know something isn't really wrong with the car and I wish I knew about fuelly before I bought the car. I might have still purchased it because it's a great car... But it has costed me a lot of stress. Hopefully those of us who purchased it might be getting checks in the future for Hyundai's exaggeration.... You'd think they would have learned

My history with 3 Mazda vehicles, 1 Honda, 1 Geo (General Motors), 2 Buicks, and a Lexus all had close fuel efficiency ratings. To tell you the truth, they were pretty spot on or exceeded... Even at 75 (although a few were before the speed limit was raised to 70). Hyundai had a class action lawsuit for doing just this thing... Yes I blame Hyundai/Kia for this. There might be other examples, sure. But saying it's an industry problem is a strange way of just shrugging your shoulders and taking it. I'd love to hear other examples of a 9 mpg decline from the companies Fuel efficiency to the FE driving 75 (in a 70, which is not really speeding on most highways in the US... or won't even get a look from a cop). Nine! That's a 24% drop.

Logical fallacies is a lesson adults should learn

JASmith... Yep... Whataboutism is thick!
 
#67 · (Edited)
Exactly, usually people use "whataboutism" when they don't want to analyze the real problem and just want to focus on what they have in front. The principle is simple, if you have people looking on what you want them to see, you can continue your own business undisturbed, don't let them compare or look around. It is becoming more a thing now that people is questioning the status quouo. I was working with VW when the scandal happened (software division). I switched to Toyota, and there we knew that as long as the attention was with the competition we can push with whatever we want. I left a few years back and move with a private supplier, thinking it will never catch up but oh well it did with this year resolution but still the fee is so small that it doesnt make a dent.

Hyundai was just the usual suspect, they will fly low for a while. Thinking that is not a well known and general practice on the industry in different aspects (not only EPA MPGs) is quite naive and I have a very beautiful bridge to sell.

Cheers!

Awe you poor thing only getting 30 mpg!
im getting 22 best with my santa cruz and should get better to but the fact is you rarely get what they advertise
I thought the Santa Cruz was 21 City /27 highway. Are you saying that you get 22 on the highway, or is that city driving? If highway, you poor thing! I'd be pissed and I genuinely feel for you.

I drove a Chevrolet Traverse hybrid on a job I used to have , and I never liked the whole hybrid concept. I recently had to rescue someone in a hybrid eco-boost, less than 3 years old, turbo sensor shut the vehicle down. I put the hybrid technology in the same category as crypto-currency- not to be trusted . I would return the vehicle and buy a normal gasoline engine vehicle.

The city mpg is fine... No complaints. It's the highway that I'm concerned about and wanted to know if it was the car or questionable reporting of fuel economy. At 60 mph, it's close to advertised but such a drastic decline up to 75.

38 = advertised

36.4 = 60 mph
33.5 = 65 mph
30.7 = 70 mph
29 = 75

So was just seeing if it was expected, problem with the programming, problem with the car itself. Plus, if anybody happens to run across this thread before they purchased, they will know what to expect. Plus I'm new to hybrids and didn't know the tendency to be less fuel efficient at higher speeds or in the winter and the 38 highway is what brought me to the party. 38 city will come in handy as well.

If you look at the official mpg v real life mpg, there is a big difference in Hyundai claims. I have a petrol i20 SE with 1l turbo engine (5 years old 33k), the official rates in the high 60's when in reality I get no more than 38mpg combined. The reason I bought the i20 was for the high MPG.
Trips of 80miles plus on the motorway give me 36mpg - lower than my combined urban driving.
In an nut shell there is no difference between driving in town or driving on the motorway.

I purchased a Tucson Hybrid Ultimate about 3 months ago. Mpg started out at 38 and kept improving to 47 now it has done just over 3000 miles from new. It now hovers between 46.9 and 47.1 doing a combination of town and motorway driving. So I'm very pleased.

I have a Hyundai Tucson Hybrid Ultimate. When new 3 months ago it started out averaging about 38mpg. It now has over 3000 miles of a combination of motorway and stop/start town driving and has steadily improved, now alternating between 46.9 and 47 mpg. I mostly have a reasonably economical driving style, but still enjoy some sharp acceleration. My only issues are with some inconsistencies with the adaptive cruise control which sometimes suggests I flip the button for 90mph! Booked it in next week to have that looked at along with some recall items.

If I remember correctly from when I was doing pre-purchase research, it seems like the Rav4 is the only hybrid CUV that doesn't drive off a fuel economy cliff at speeds above 60-65 mph. If highway fuel economy is their main/only concern, it's probably a buyer's best option in the segment.

Compared to the Rav4, the Tucson has an automatic transmission, a more modern interior, more cargo and passenger space, as well as better handling and performance. The Tucson's real world highway mpg is a somewhat bitter pill, but the silver lining makes it a little easier to swallow for me.
 
#85 ·
Yeah, Car and Driver rightfully places the Rav4 in 6th place though in its segment, rating the 22 Mazda CX5 Turbo, Tiguan, and Tucson in the top three, in that order. As was mentioned before though, particularly the Japanese tend to perform at or sometimes over their EPA mpg rating, and C&Ds test of the CX5 turbo resulted in 30mpg highway, 3mpg higher than its 27mpg rating. But throw in mixed driving, and C&D only managed 21mpg in their real world test, as larger turbo engines don't perform as well as hybrids in stop and go.

I have seen no reduction in MPG during 'break-in' of my Hybrid. For a mixture of 55mph highway, lower speeds going through towns, 10% I-5, and perhaps 20% city driving, I am consistently right at 40mpg.

Hit 1071 miles yesterday and on-board accumulated is 40.5mpg. Actual data at my last fill up matches this (at 788miles, I had input 19.7gal = 40.0mpg. at that time, the computer had it at 40.1mpg).

I have rear tires at 37psi, front at 38psi cold and have been doing plenty of spirited driving on Highway 101, probably 10% in Sport Mode, testing it around corners at well over the recommended speed and testing acceleration grip to 60-70mph, including on wet roads...but much of the time driving to get good mileage and paying attention to when it goes into EV mode and working to keep it there as long as possible.

That does not sound right at all even with an engine not broken in. I'm a little concerned about your issue as this is the car that I would like to purchase.
as a former warranty manager I say bring it down to the dealer and talk to the salesman as well. Waiting 10 days for a case manager is very upsetting which concerns me even more.
Which model hybrid did you buy and can you share part of your contract so I can make a comparison. would like to talk with you off line if that is ok too

Well I did make my first payment (majority of the loan to decrease interest) after this discussion and figure that 29-30 mpg is normal if traveling at 75 and I'll have to live with it. In the city, it really is a great vehicle, I totally agree with you on that. Plus, some have said that it improves with more miles put on the car. I finally got the call from Hyundai yesterday and was told that getting 29 mpg at 75 mph was "within normal operating parameters)... I didn't argue this after hearing others testimonials. The only gripe is that I wish they would have an audible alert when the car's sensors cause the Lane Keeping Assist to stop working. I do keep my hands on the wheel and I'm attentive, but it can be alarming when you realize that you're not staying in your lane!

Yeah, I think if highway economy is goal, aerodynamics are king. I think the Ioniq was .24Cd or something like that, but its getting long in the tooth and I think is going to be redesigned soon. Its too bad they don't make a Sonata Hybrid that looks as cool as the N-line regular Sonata! Those are supposed to be really slippery at speed too. SUVs, even crossover types, are ultimately pretty high riding and chonky for crazy high speed efficiency.

I have to disagree with some posted comments on breaking in the engine to achieve mpg estimates. I am having the exact same problem with my new 2022 Tucson hybrid. I got under 28 mpg on city driving and under 31 mpg o
n the highway. No other new vehicle I ever purchased underperformed like this. They all ran at or above the EPA/DOT fuel economy estimates. There is something wrong and I just started the process to resolve the issue.

I did test it on the highway and it gets 37 mpg... When you drive 60mph. 78 mph gets you 28... When I talked to support, they said there's nothing I can do and that the car was performing within the correct parameters. I accepted it but I wish my salesman would have let me know the discrepancy since I told him I was planning on taking many long roadtrips. Still, not bad for such a big car. Feel free to pm me if you want to share experiences. I know exactly how you are feeling
 
#106 ·
which is interesting since the absolute best mileage I’ve gotten was a 750 mile road trip with the overwhelmingly interstate high speed driving. I still think there’s a glitch in the software which controls which power system is to be running. There’s no rhyme or reason why our mileage fluctuates as much as it does week to week driving the same route.

I purchased the 22 Tucson Hybrid 2 months ago. I mostly drive City but some highway. My average MPG has never exceeded 28MPG!!!!. I'm not an aggressive driver and I understand how hybrids work. I've had two Priuses. I bought them new. They always met their advertised promise of 50-55MPG. In fact, they've exceeded it many times. So, I think HYUNDAI is wrong on it's MPG. Don't buy into this "breakin in period" or "you're driving too aggressive" or "it must be where you live." Hold these people accountable. I had to pay 4000K over MSRP because of the car shortage (even though they had plenty in their lot). Also, my check engine light intermittently comes on and off. I had to leave it at the dealership in Beaverton, OR and take an UBER home because they have no loaner cars (probably sold them). I would NOT recommend this car at this point for those looking for an all wheel drive hybrid SUV that can get 35MPG.

I bought my Tucson SEL Hybrid from a dealership in Beaverton (probably the same) back in May and have put about 3k miles on it. During that time I've driven to the coast and along the Gorge several times as well as around town. I was getting advertised mileage during the warmer months, but it's dropped several mpg's since the weather got colder. City driving is closer to 28-32 mpg's now, and I am guessing it's because the engine is running more to heat the cabin plus the fact that fuel consumption increases with colder ambient air temps.

I now have almost 11000 miles on my Tucson, and I have seen the highs and the lows.
Just got back from a trip to Arizona. I had one fill up, from Albuquerque to Dalhart Texas going 80 MPH, where I got 37 MPG. Of course from Albuquerque to Tucumcari is mostly downhill. :)
On one fill up on the way out, again 80 MPH, I got a little over 27.
What's frustrating to me is, on most downhills the computer takes too long to go into EV mode. I can manually disengage the cruise control until it goes into EV mode. I then re-engage the cruise, and majority of the time it stays in electric only mode. Why does it take the software longer to engage?
I have to agree that the software could use a little tweaking.
