Hyundai Elantra Real World MPG 2011 MY and earlier



  • My problem is the car is not getting the gas mileage or anywhere near what I bought it to do. The problem is NOT my driving with the heat/air conditioner on/poor inflated tires, wrong oil, wrong gas, wrong gas station/driving too fast/driving too slow/driving in rain/driving in snow/having the radio on, cd playing, windows rolled down or talking to my kids in the car. The car has a defect. The 08 Elantra is a completely different vehicle aerodynamically. Hyundai owes it to its customers to find out WHY some of these cars are not functioning and some are. I am getting 40 percent less gas mileage than expected. I could drive 15 mph on cruise control and maybe hit 27 mpg. Thanks
  • Thanks. will do. I think some people are getting the mileage but clearly a good percentage of people aren't. Hyundai should look at the reason why instead of trying to blame the drivers. There may be a part that is manufactured differently in some of these cars. 40% less is a lot of gas mileage not be getting. shame on Hyundai. If i went to a grocery store and bought a gallon of milk and when I got home it was only a half gallon, the store would take it back. that is good customer service. there is an implied warranty when you buy a product (gallon of milk/or a 23,000 car) that it will do/be what you bought it to do/be. I am spreading the word that Hyundai does not stand by their product. My daughters each of a hyundai (which are fine cars) but they will never buy another one again.Saab had awful customer service and look what happened to them.

    You know, one quick way to tell if your car has a defect and get supporting evidence is to rent an Elantra for a day or two (Enterprise has them, and maybe other rental companies). Be sure the tank is topped off and drive it the way you normally do and see what the FE is (both computer and at-the-pump measurements). Then drive your car for the same length of time and on the same routes, and compare. And be sure to document everything. If you see a big difference in FE, take that info to Hyundai. If you do NOT see a big difference... that greatly reduces (but doesn't eliminate) the odds of a defect with your car.

    There's some other things you can do, also, e.g. take a run of at least 10 miles (longer is better) on a level highway at a steady 65 mph, resetting the FE meter when you hit 65 mph. Best to do the run in both directions to negate wind and hills effects. Be sure the tire pressure is at spec. Based on published tests, you should be able to get 40 mpg or very close to it under those conditions. If you get considerably below 40 mpg on that test, take those results to Hyundai.
  • Thank you for the suggestions. My dealership test drove it and got poor mileage too, but Hyundai refuses to do anything about it. The district manager came up and just shrugged, saying the engine checks out fine. Its false advertising. :(
  • Any new news with the dealer? --I am headed toward arbitration over the frustarting; I had an independent garage drive it for three days--they got 18.3 mpg, I guess I am driving it conseratively getting 22 mpg.. sigh.
  • My frustration is a mirror image of yours. When I saw the new 2011 Elantra advertised online I thought it was beautiful! Then, I saw the 29/40 MPG and had to see this car. I drove the car and loved it! Perfect fit. Turned on a dime. Beautiful styling, roomy interior and I loved it! The first few tanks were a dissappointment. After speaking with a few dealerships, they ALL assured me that the mileage would improve after 7,500 miles which is the “break in” period. REALLY? Then, I called Hyundai Corporate offices and talked with a customer service rep. He had no idea of the “problem.” REALLY? I have averaged 24 MPG since I bought the car...a little less for the first few tanks. AND, I can only drive 250 miles on a tank!!! Yuck! Seems like I’m always stopping to buy gas. So, how does a major car manufacturer get away with advertising ”70%” lower MPG. The average should be about 34 MPG if you drive 50% city and 50% freeway. I don’t care what the EPA comes up with in their tests. The car manufacturer needs to do their own tests and not rely on the government test results. How can we be compensated for this great deception?
  • I just brought this case to lemon Law but Hyundai says mileage is not covered under their warranty. Some states (CA for one) is going the class action lawsuit route. Check out Consumer Watchdog's site. I live in Maine but bought my car in MA so I am going to be asking around for a MA attorney who might take it on. We got totally ripped off with no recourse. No other major manufacturer could get away with such deception. If you have facebook, post your comments on Hyundai's facebook page. Tell everyone you know. They are so condescending and their customer service lies to everyone.
  • I just returned from a 5000 mile trip (mostly highway) that went from Austin, Tx to Maine and returned. 2 people plus luggage and camping gear. From Austin to Niagara Falls I was getting 42-44 mpg driving 60-70 with AC on, with tires at 30-32 using regular gas in my 2011 Elantra GLS with 16" tires ( the tires still look new). I never use cruise control. I now have 20,000 miles on the car. When I pull 2 kayaks and a small trailer I get around 34 mpg. If you are not getting at least 35, there is either something wrong with the engine or you have a heavy foot.
  • I agree I own a 2011 Elantra and in city limits with a speed limit of 30-35 I usually range about 25-28 mpg.... now on the highway at a speed limit of 65-70 I've gotten up to 47.6 mpg. So i take the good with the bad and it is what it is. BUT I also have the rattle that most talk about on this forum, I just havent made it into the shop yet.
  • I have driven my 2011 Hyundai Elantra GLS for 11,100 miles over 18 months and the car has consistently averaged 21 to 22 mpg on each full tank of gas. I drive 10 miles a day round trip to and from work in stop and go traffic and a few times a month, I travel about an hour each way on a parkway to and from a major city. I had the car serviced at my Hyundai dealership yesterday and complained that I have been averaging only about 22 mpg but the car is rated at 29 to 40 mpg. I was told that they checked the car and it is functioning normally. I asked does that mean that 22 mpg is normal and I was told yes. I then asked does that mean the car should be rated at 22 mpg and not 29 to 40 mpg and I was told yes.

    Your problem is your short commute and stop & go traffic. The car is just getting warmed up when you are at your destination. If your stop & go traffic is extreme recognise that you are constantly accelerating with little cruising. Your occassional hour drive on a parkway will not make a big difference in a tank of gas which otherwise consists of your daily short haul stop & go.

    Is not the definition of the "city" rating "stop & go traffic" (i.e., traffic lights and stop signs)? The City rating is 29 mpg and I get only 22 mpg.

    My previous car was a 2007 Nissan Sentra 2.0S. It was rated at 25 to 33 mpg. With the same driving patterns as with 2011 Hyundai Elantra GLS, at 11,000 miles, I was averaging 25 mpg. I guess that means that Nissan's mpg ratings are accurate and Hyundai's are inflated. I wish I would have known that before I bought the car.

    Yes, but when an engine is cold - really until it reaches full normal operating temperature - the ECU runs a richer fuel-air mixture. More fuel is burned to keep the engine running smoothly, avoid knocks/pings, and bring the engine up to temp quickly. With your short commute the engine is not reaching full operating temp so the ECU never switches over to the leaner fuel-air mix.

    It's entirely possibly that Hyundai's and Nissan's engineers have different programming standards and different ways of handling their particular engine's characteristics.

    I'm not making excuses for Hyundai, nor do I think Nissan's tech is necessarily better. Just trying to explain the problem with a short commute and that different manufacturers will have different approaches to engine management.

    When you have some extra time, try running the car until the temp is full normal, and then some for a few minutes to make sure. Then reset the trip computer and see what mileage you attain.
  • 2013 Elantra GLS, auto. After 5K miles and reading allot of posts about this car's MPG I think something is clear: your city mpg will vary between 22 to 24, while your highway will be around 34 to 35 (mile marker to mile marker, once at speed on a flat road) Combined = 27. Hyundai's claimed MPG estimate 15% overstated in city driving and 10% overstated on the highway measured by the ACTUAL FUEL USED / MILES DRIVEN. My 2007 Sonata gave me 17 city and 32 highway and a combined 23. My dealer confirmed this.

    Hyundai gears its trannys to give high mpg's on the highway, but at the sacrifice of really bad mpg's in acceleration and in stop and go city driving. And those really bad city mpg's rapidly decrease a much larger number of highway mile mpgs. THE REDUCTION IN COMBINED MILEAGE HAPPENS FAST!

    It's a game.

    Just so it's clear. Every car for sale in the U.S. goes through the same exact EPA tests for both city and hwy. They are accelerated the same, braked the same, driven the same speeds, go through the same amount of simulated stop lights, etc etc etc. It's not the manufacturer's's the EPA's test. The manufactures have to test them in strict accordance to the EPA criteria and the EPA randomly does there own tests to verify the manufactures. So the claims are the manufacturers but they are derived from the EPA test and not some arbitrary manufactures test. The EPA test is not just heavy, stop and go urban traffic simulation. It's a combination of urban, suburban, light blvd etc to simulate "city" driving in Des Moines as well as New York. They are both city driving but can substantially different mpg results. So they try to reach a compromise to give you an idea of what kind of a range you might expect. You have to apply your conditions and decide if you are probably at the bottom or top of the range for your expectations.

    That said, it would be almost impossible for the average consumer to exactly match all the driving conditions that the test is made up of. If you actually read the EPA sticker it will give a range for city and a range for hwy with a number somewhere in between each boldly printed. I don't know what the exact numbers are on the Elantra but it is probably something like 22-32 for city and 34-42 for hwy. What that means is that if you drive only a few miles each way to work through a lot of urban stop and go traffic, your mpg will probably be at the very lowest end of the city range which would be around 22 or 23. That kind of driving is about the worse you can get.

    It's been stated often that the Elantra doesn't have a lot of torque or grunt off the line. If someone was used to a certain amount of speed when taking off with their old car they may just push the gas pedal a little harder in the Elantra to get that same feeling of grunt or speed off the line. That will affect MPG greatly and possibly explain why another car may have performed as well as the Elantra even though it's mpg ratings were lower as estimated by the EPA.
  • The car is a rip off. Hyundai has totally mis lead its customers. They need to stop blaming the drivers.
  • I just purchased my Elantra last week, and averaged 31.9 mpg. Please note that the majority of my driving is hwy - 60-65mph and I do use the cruise control, as well as have it in ECO-mode. I've read alot of the posts and reflect back when I purchased my '06 Civic, which at the time EPA MPG 30-City and 40-Hwy, and I too was disappointed in the beginning when I wasn't achieving that mileage that had been posted on the window sticker. Several factors played into: 1. City driving - living in San Francisco, with it's many hills and numerous signal lights, I was achieving 23 mpg. 2. The break-in period for the car's engine. One has to take that factor into consideration. Once my car had acquired close to/over 10k miles, I noticed the mpg improved. I sold it to a friend of mine earlier this year and he liked the fact that I was getting mid-30's city/hwy combined driving, and achieved as high as 47.8 mpg straight hwy - driving from Sacramento to San Francisco, Bay Area - not bad for it not being a hybrid or diesel. Lastly, if you keep your car cleaned (washed regularly and waxed a couple of times a year), as a smooth finish allows the air to flow smoothly over the vehicle, thus reducing drag, keep your oil changed on a regular basis, clean air filters and proper tire inflation, will all contribute to improvement to your mpg. Heck, I got 31.9 my first week, and its only got a little over 200 miles on the OD, I'm anticipating continued improvements in my mpg as my car ages. I'm quite please with Elantra; quite the car for the small price - nice standard features that aren't usually found in this class of car. :shades: Best of luck to everyone!
