    Hi - this discussion is about fuel economy on the Elantra. You can see what lease deals others are getting in our Elantra Lease Questions discussion, and if you still have questions, that's the best place to post.

  • We have the same problem, the dealer said that the tires need to be rotated every 7500 miles. The thing that really surprises me is that our rear tires are in worse shape than the drive tires.
  • Every time some one complains about poor mileage, some one reply's , your a led foot.This car sucks for mileage. I own a 2012 Elantra GLS with 38K and in echo and cruse set to 65MPG, your lucky to see 29 to 31MPG. I have owned older Hondas that saw over 40MPG on the highway. The faults of this car far out way the good. Poor suspension, MPG, Factory tires. Have you ever tried to drive this car on a narrow, twisty, bumpy mountain road? R.J
  • I seems to me that you don't understand how the MPG is displayed. Its is not a instant reading but a cumulative look at your MPG.

    So, if your doing a lot of city driving and your MPG is say 26….its going to take a lot of highway driving at 65 to overcome that MPG of 26.

    I normally get about 30 MPG combined. I recently drove from DC to Harrisonburg VA and at the end of that drive I had pushed my MPG to 40.

    You're not seeing 40 because the majority of your driving is city.

    The car can do 40 but only if the majority of your driving is highway and 65 MPH.
  • @aviboy97 said: An interesting article I stumbled across yesterday. I wonder if a group like this actually has any weight to throw around to help those who are experencing poor FE with the Elantra? claim/ Thanks! I read the article. Consumer Rpts. auto buying guide has been my auto bible since I started driving. They were a mainstay in my family for many, many years. In 1979, they were spot on with their review of my Dodge Colt (problems and good stuff). But I bought other cars due to their unbiased reviews. I used it for the Elantra, which was one point less for their driving test than the Subaru Impreza. I believe in its accuracy at that point in time. Times have changed, though. They no longer do the drag coefficient rating and I'm sure other ratings I've forgotten. They never mention the batteries in the car were rated the lowest of the low some years ago by them. They don't talk about the flimsy gas cover. They don't mention the lousy tires but add putting sporty tires on a new car may not help. I guess they're saying deal with it until you can do your research and put on what you think is best. In what I see as an oxymoron they state, "Fuel economy of 27 mpg overall is nothing special ..." But Fuel is erroneously stated in their box stats at 28/38. Honestly, I think they missed the boat on this one.

    We know the facts that if you drive at 55 mph, your gas mileage will be higher. You no longer can compare unleaded ethanol with unleaded. Ethanol and all the grief with it is the standard today. Gas mileage drops and the car should be tested with it. Yes, EPA results have been higher than actual driving but not this much. Add to that if people are depending on the car computer to provide accurate MPG results, you're assuming it's correct. I don't. I have a spreadsheet with running mileage results from manual calcs.

    Fowler3 suggests manufacturers are out to trick consumers. I don't know if it's true or not but Hyundai has had massive advertising campaigns/blitzes and I've read the metrics. Have their cars improved over the last 20 years - they look better and are designed better. Are they better, though? I don't know. For example, my Elantra has the worst non-performing tires I've ever had. They toss in a cheap battery. The gas cover will break one day; I've never had anything more flimsy. So, while other manufacturers don't seem to go to this extreme Hyundai does.

    I wish (I'm fantasizing) our government would so something about manufacturers who receive "x" number of the same complaints (real ones) on their vehicles. But it won't happen. Welcome to free enterprise.

    In London Ontario Canada there's a class action law suit taking place, March 14th any submissions have to be in by march 12th, regarding the poor fuel economy, and hyundai is trying to settle with everyone here like a one time buy out,, if your canadian and want to take place or add insite to your poor mileage, contact McKenzie Lake lawyers LLP 1800-261 4844 ext 287 regards inquiries to the case,, I hope Hyundai is made to pay for lying to use all , and if you want more information goto

    I purchased by new 2012 Elantra GLS in July 2011. The car got the admiring looks and performed well without problems for the 2 year lease I had. I waited about a year to break in the car, 9k miles before I started to seriously look at why my mileage was not getting the claimed mileage the EPA recorded on the sticker of 29/40 hwy. I left the comfort and performance in my Nissan Rogue that averaged 25 MPG for the Elantra that was averaging 27 MPG, using the standard filling my tank full and dividing the gallons against the mile driven. The Elantra perform poorly in the city driving of 25-35mph, with stops every few blocks. According to the car's computer, I averaged 18-19 MPG, when it was rated at 29. So I only got 200 miles on a tank full. I expected to average at least 30 mph for combined Hwy/City for this type of car. I did pursue the rebate when Hyundai lowered the MPG, but I felt that the car wasn't even getting the new adjustment mileage. This rebate total $55 for the first year and $25 for the second year, which came in the form of rebate credit, but you had to visit the dealership to acquire the rebate. The average 27 MPG mileage I got was in the economy mode, just 1 mile better than regular mode. This is a California emissions car with 16" tires, 1.8L 4cyl. I would coast the car in neutral and roll the car 1000 feet to a stop. I'm 6'3, 230 pounds, and had up to 50 pounds in the trunk. I traded the car in for a more comfortable ride, a 2009 Hyundai Sonata Limited 4cyl. A much heavier car with larger 2.5 L engine and I have a real spare tire to boot! I get the same mileage as my Elantra in town, but overall I get 3 mpg less with the Sonata. I think the Elantra's smaller engine is just struggles on the MPG in the city. I think on the freeways it's true to new reported 38 mpg now. But realistically I don't drive the post freeway speeds. I just know that I got better mileage driving a Honda Civic and a VW Jetta and was averaging 32mpg with better performance. I just expected the Elantra's claims should be truthful.

     Update w/nearly 17,000 miles at 13 months since new. Using 100% (ethanol-free) gasoline, tires at 38psi & my alignment is very very good, careful driving, ~ 15% city driving, I've averaged 38.5 mpg(hand calculated, not trip computer). Tho the engine has 148 HP, its torque is a miserably low 131 lbs-ft. Not only will you NOT get hot performance, but the low torque will kill your mpg if you try to get it to perform. If you accelerate as fast as everyone else on the road, say bye bye to mpg. From careful mpg records from 3 previous cars, 100% gasoline raises mpg from 8% to 5%. Higher air pressures help a lot, too. But lower your air pressures in rainy or snowy weather. 

    For those with poor mpg, make sure your spark plugs are gapped properly. One Chevy forum had lots of complaints of poor mpg. Many members discovered their spark plug gaps were way too small. Re-gapping properly & most all members got considerably better mpg!!!!! So check them plugs!
