Hyundai Elantra Real World MPG 2012



  • Thats a nice sticker, to bad most of the consumers fail to read the fine print, because it doesn't apply to them, The numbers in bold are the ones that count as far as their concerned.
  • Took the car to the dealer and they pressed the reset button and drove it 15 minutrd and said i was getting 42mpg... I tried to explain that it will drop off shortly after. My trip to philly proved it to me. I started out 40+ and by the time i reached philly with the car on cfuise contril i was in the mid to upper 30's. By the time we drovr back we were at 33.

    Please excuse the typing. Im on my phone

    Did you drive around in Philly at all or was it all highway?

    What was your speed to (and from) Philly? What was the traffic like--did you have to stop or slow down/speed up much? Weather? Did you do any passing or maintain a steady speed? Any differences between trip to Philly, and from Philly?

    I see this kind of thing a lot.. I'll drive on the freeway to a city, get really good mpg on the highway (if I watch my speed, traffic is flowing, weather is OK), then hit my destination and drive around town for awhile and I watch the average mpg drop. Then I get back on the highway to go home and it recovers somewhat, but not completely.
  • I just a flash from my dealership in East Texas that fixed my MPG. I was getting bad then good then, the really bad, the lowest I have gotten is 26 calculated by me, and after the flash I've been able to get 42 I'm ecstatic
  • '12 Hyundai Elantra owners. After 12 glselantra got the flash from the dealership his ghastly mileage improved from a low average of 26 mpg to 42 mpg. Wow! :surprise:

    2008 Mitsubishi Lancer GTS

  • Ok, so when was this flash done? And would it be for only GLS Elantras or all Elantras including the Limited? I had my 1st service done on my Limited late last month, and I was told that all the codes were up to date and that nothing was changed, and that my car was operating normally, yet I'm still getting below average mileage even though I have noticed a slight increase due to slightly warmer temps where I live.

    If this flash update was done very recently, and if the results are true, why doesn't Hyundai roll this flash out to all the cars that are on the road?

    I just want some answers.
  • Good news about the update, does anyone know if it is at all dealers?

    Also was the 42 mpg on the computer or calculated ? I find that my computer is normally off by about 3 mpg.

    What kind of driving was on this tank of gas? Mostly highway, mix, ect...?
  • I don't know if it was specific to gls models or all I just got yesterday and averaged the 65mph highway trip for 35 miles, I calculated it myself, Ive been driving alot of city after I filled it up yesterday and thus afternoon I will take another highway trip for 50 miles I hope to get the 33 combined. Hyundai probably does not want to admit there computers are faultty and the reason why everyones MPG is real good or really bad, kinda like Ford's update for their focus powershift transmission they released a couple of months ago.
  • I just finished a 118.5 mile trip with 30% city and 70% highway. I filled up the at the same pump, the same way, and got 40.1 MPG, the computer said 37.5 though? My average speed was 43, where the last one was 40 MPH. Also, the car seems to run smoother, and has more power. It doesn't downshift from 6th to 5th, on most hills ( my route is 60%+ hilly) my average speed on highway was cruise set to 65-70. I had to go thru 16 miles of heavy traffic also. I recommend everyone to check with their dealership and have them put the new ECM REFLASH, CLEAR CODES AND RESET ADAPTIVE LEARNING AND ALL ( according to my ticket of what they did) oh BTW I only have 6900 miles
  • read my other post
  • TSB-11-01-069, this is the TSB, that has all the info on it. It not only covers 2012 Elantra GLS, but also cover all Elanta models, (GLS & LIMITED) for the 2011 & 2012 model years. The only difference between a GLS and a LIMITED is the interior trim(leather/cloth) and the tech. pkges. They all have the same NU engine, 6spd manaul/ automatic. Might try checking with the dealer about that update. Not all of them require the PCM flash.
  • I work at a Hyundai/ford dealership in the service department and own a 2012 Elantra. It frustrates me when so many people bash this car. I worked for another hyundai dealership four years prior then i switched to the ford Franchise. Why you ask? As most people know we get paid on a commision basis. I work half as hard to make the same amount of money as i had to woth Hyundai. Why? Hyundai has a better warranty and require less maintanence or repair than most domestics.
    Another thing people think is that their vehicle is covered bumper to bumper for 10 years. Let's be realistic here people. do you think everything will be covered under your warranty for ten years and only pay 19-20k? I can tell you that everything you will need to know is in that owner's manual in that glove box. Iv'e had ridiculous questions about thier warranty. Is oil changes covered? an object went through the grille and damaged the a/c componenets. With the problem with the a/c the customer said she was going to sue hyundai for the repairs because that part shouldnt be in that location and it was poor engineering. Wow every vehicle that has been massed produced with a/c has had the condesor in the same exact spot.
    With all that being said, Hyundai still has the best warranty. 10/100k Covers engine (as long as you actually do your oil changes) Transmission (as long as it has been maintained) engine seals, water pump, oil pump, cv axles, front wheel bearings, transmission seals,
    No other domestic will offer you a 10 year warranty. why? their warranty repair cost would be too significant.
    I have LOYAL customers that come in and have no issues with their car. One inparticular uses his 2009 elantra limited for his job and has acumulated 215,000 miles. this is his fifth hyundai by the way. All which he sold inspected with over 300,000 miles.
    Everyone thinks Getting your car maintained and serivced at a dealership. You walk out the door paying 50-75 a crack at jiffy lube and have someone that was previously employed as a fry cook at the burger joint across the street work on your car. Typically you can get a synthetic blend oil change and tire rotation and an inspection from a Hyundai certified technician look over your car in between 30-40 plus tax.
    As far asactual repair cost you will pay a litle more at a dealer, but there is a reason. Say you have 50k on your car and you needs brake pads Dealer might charge you 225-300 depending on location. A side shop will tell you we will give you lifetime brake pads nstalled for $99.00. Well now your at thier shop and they noe tell you that your calipers, rotors and brake lines are shot and the only way your going to get those lifetime brakes is to get your brake system up to thier Standards. But 15k later your pads are worn down and need to be replaced again. sure they will give you those $10 brake pads but you have to pay to put them on. hmmmm wasnt a very smart move now was it.
    For a check engine light we genraly charge $90 to check it out. "$90? wow autozone will look at it for free" Guess what that'sall they will do is look at it. plug in a scanner print you the code and tell you ehat it could be. Now you ran backand forth to the part store multiple times and wasted hundreds of dollars it get this check engine light off. It couldv'e been something as simple as a computer update and you would have beenout of the door for $90. You pay the money and you will know EXACTLY what is wrong.
    Something most people dont realize is the Service Advisor that you meet when you drop off your car is actually what his title is, an advisor. He will help you make the right decision on what you should do for your car based on your time and budget. I myself like to put myself in your shoes. i will tell you what you need and what you can put off and what's not necessary. Thats is how you build a relationship with a customer no take thier hard earned money and run like most people think we do. Also that survey you recieve after you pick up your car is how he keeps his job. Say you picked your car up because the part had to be ordered for your car and it wont be in for a month you give the dealership a bad survey. Guess what you might have just costed that man behind the desk his job for something that he nor the dealership had no control over. In my place of employment a bad survey like that will cost me $500 a month for three months. Not fair but it's my job to make sure your happy. Remember those peopple behind the desk are people too they didnt build your car or work on it and they get just as upset as you do when things dont go like they should. If you come in and treat the man behind the desk like a human being i promise you that they will go out of their way to help you. most service advisors take care of 15-25customers a day. it doesnt sound like much but when you have to plan corrdinate and hope the parts are in stock, hope the technician is in a good enough mood to take care of you if he likes you and not put your vehicle off for someone else's.
    Finally mpg Hyundai didnt put that 40 mpg tag on that sticker, the EPA did. And if your lucky enough to have a state that doesnt pump their fuel with ethanol you might get close to it. Ethanol is like the difference between top shelf and bottom shelf liquor. you think it is doing good for the environment but if it causes you to burn more fuel in a ZERO emissions vehicle what are you gaining? It's another way for oil companies to boost profits. Look i drive 11.5 miles a day 10 of it is interstate and i average 26-27 mpg. Sometimes better if i use a different gas station. I will tell you i jut dont hear gas mileage complaints about the Elantra. I get complaints about all new cars. And for those of you that think that there is soe magic reflash that is going to restore your gas mileage your wrong. Hyundai does not have any tsb's in any such subject. What is done it they reset the adaptive values of the ecu. What this does is Delete your driving habits and history out of the computer and restore it back to factory settings. We do it any tie a sensor, transmission engine etc is replaced. What really frustrates me is when people say they are going to sue. Really? Can you find something elseto complain about in your perfect little world. Sue yeah thats the answer just drive the cost of those new car up so you can have some extra chaneg in your pocket. Kind of what health insurance companies do get a little noepay alot later. Below is the onlyEPA Gas Mileage Estimates
    Here is all the information from the Hyundai technicain website in regards to mpg.
    With the cost of gasoline being near an all time high, many customers are paying much closer attention to their gas mileage. As a result of this, some of them may believe they're not getting the gas mileage they should, or what they saw listed on the window sticker (EPA Label) at the time of purchase. This article will attempt to
  • That tsb if for a heater pipe fitting and inspection and or replacement for a 2012 elantra produced betweed October 5 thru October 11th 2011.

  • Bad idea to continue filling up after the pump stops. it will contaminate the evaporative emmisions system and be a costly repairs because its not hyundai's fault you didnt read you gas cap
  • quality if fuel. if it is a small gas station the fuel stays in the tanks longer. it accumulates water. reduced mpg also ambient temperature and road conditions play a crucial part as well
  • your transmission is programmed to shift into the next gear as quick as possible. lower rpms better mpg. if your dont feel that it shifts to your liking slap the shifter to the right and control the transmission how you see fit. i hope this helps .Eco mode retards your exhaust timing and advances your ignition timing to reduce engine power and fuel consumpstion.
    I'ts been stated many times before Hyundai didnt post the 40 mpg mark on the window sticker, The EPA did. The answer is it's not a performance vehicle you either drive it like miss daisy or put the pedal to the metal. It Shares the same transmission as the tucson, sonata, accent and veloster. If they put it in all those vehicles it must be doing something right
  • Thanks for the info, I got that TSB from the NTSB website, but all it gave was a TSB #. Sorry about the mistake.
  • I have 11,000 miles on my 2012 limited and I can tell you I do 70-30 highway/city driving. Research the factors that affect gas mileage and it will really help you maximize your MPG. When they test these cars it's done with one driver and a complete empty car. Now all of us drive our cars with people, stuff in the trunk, etc. Trust me every little pound makes a difference in how much gas you use.

    I usually drive my car on hilly interstates with 4 passengers and luggage, drive from 65-70 mph and I get 38 mpg. I do have times that I get some gas that doesn't seem to burn as well so I get a little worse at times so you have to be consistent on where you fill up your car. Now on my MPG, I can tell you this since I read gas mileage drops for every 5 mph over 60 that you go...I tested that. I used to drive 75 on the interstate and got 33-34 mpg. Now I drive below the speed limit in my state and I have increased my MPG 38. I'm a data analyst so I really watch this stuff since I drive so much so the data does not lie. When you really watch how your drive and properly maintain your vehicle, extra stuff in your car you don't really need; you will do far better on your pocket book. I don't keep my golf club in my car when I don't need them, that's like having an extra person in the car hurting my mpg. Look at it this way, it's like asking our bodies to carry heaving boxes up's more weight so it takes more work to move the same distance.

    Now for town driving - just too may factors in my opinion. stop and go is just how it is. I have found my elentra gets better around town mileage than my mazda 3 did. I get around 31-32 now matter how I drive it. Unless you have a hybrid, you just have to be realistic here. I think a lot of times we don't notice how hard we take off from a stop light because we are all in a hurry to get some where. Taking off consumes the most fuel.

    All in all - I think the elentra gets as advertise on MPG. But if you are really having problems with the MPG have a dealer technician run a diagnostic on the car, it might need a slight adjustment that is hurting your gas mileage. Use the great warranty they carry!

    David: Thanks for the informative post from an experienced tech that actually worked on Hyundais. We bought a 2012 Sonata GLS 2 months ago and the car is great. 65-70 MPH yields 36-38 MPG and even at 75+ it gets 33. City MPG all over the board due to varying conditions, but close to EPA.
    I agree with your comments on dealer service and warranty. I feel the warranty is worth a lot and will definately get the oil changed every 3000 miles to protect that warranty. We also got the Assurance guranteed trade in value in 12/2011 that is not available on all the cars in 2012. 67% after 30 months is pretty good backup if you wanted a new or different Hyundai.
    Our 2.4L 6-speed auto trans shifts very well and does have the programming set up to upshift faster than downshift for MPG maxxing.
    Great cars for the money and with that warranty the Sonata was no brainer. The highway MPG is close to the Elantra but not the city.
    Thanks again for the facts and professional view.

    Great comments in a real world view. See my previous post to David's comments. We see exactly the same changes with speed on or 2012 Sonata. Max MPG at 65-70 using Shell or BP (Amoco). City MPG only 22-24 due to added weight of Sonata. We also avoided the low profile tire trap and run the 205x65 HR16" tires at 35#. A little common sense and paying attention to details results in maximizing the MPG and at $4/gallon and headed up thanks to the oil companies business plan of wanting to pay more for imported crude to make 6% of $100/bbl vs. 6% of $35- oh well!
