MPG Question by he07drivr
Sep 28, 2007 (7:21 pm)
Reply
I bought my car back in November 2007 based highly on the EPA gas mileage rating compared to others in this price group. My question is this: Was the EPA gas mileage testing performed on a car that was reporting better mileage than true performance? Because if the EPA gas reading is now lower than reported when I purchased my vehicle, that would have effected my purchasing decision significantly and I may have gone with a different vehicle. In which case, I would demand the option from Hyundai to give me a trade-in for a similar vehicle with similar or better EPA MPG estimates at little or no cost to me. Its bad enough that we'll be hurt when we go for a trade in thanks to the increased depreciation caused by this critical flaw.
 
Does anyone have any comments on this?

Went into my local dealership and after waiting for about 30 minutes I was informed that they misplaced the disc that had the update on it. When I suggested they download it they said they tried, "it didn't work", It ended with them promising to call me when the new disc came in. Sounded suspect until I called a couple of other dealerships in my neighborhood to find none had the update, but should be in by next week (or so they said). Anyone else getting the same? or am I getting the run-around? I'm in the NY area.
 
Thanks.

you might have problems "demanding" anything from a company the size of hyundai.
 
every car's 08 EPA mpg is going down, but the 07 and 08 elantras will get the same mileage, it all depends on your driving habits.

Speedo Error 2007 Elantra - Now MPG Query by ebbuts

My MPG since being reprogramed is about 2-3 MPG less than when I got it in Feb. 2007. In town with air is running 24-25 MPG. I fill my tank to the very top each time I fill. Granted it takes longer but if you stop when it shuts off itself, my car takes about 3-04 more gallons. That is where people are getting their huge in town and road MPG.
 
I was at the dealer this AM for an oil change. I asked him about the letter and re-programming. This dealer had done a re-program on mine in June 2007, long before Hyundai finally came out with one officially. He told me they wanted to check mine to make sure it had the #91 re-program per the TSB which it does have. So my car has been OK since June 07. Get your cars in and get them fixed up guys. The wait for some of you is still better than buyng new tires. The dealer also said the 3% additional miles should be automatically extended once your car is fixed.
 
Back to MPG. No matter what, this 2007 gets better mileage than my 2001 ever got. Have no idea why but it does even with the re-programming done.

Yeah, Sorry the EPA gas mileage is not really the manufactor's mileage, it's determinted by tests which you can read about here. http://www.epa.gov/fueleconomy/, A goverment Agency.

I usually fill up when the gauge gets around 1/4 tank and I fill it up using the slowest pump setting. Usually I get 26/27 MPG from the computer and less than 1 MPG better than that based on my math (from the refuel amount vs. miles).
 
The reprogram was done only 5 days ago and that includes a long highway trip, so my numbers for this tank aren't representative of my usual driving. However, I am seeing MPG numbers about 1 MPG less than I would expect.
 
If I took it easy (~60mph on the freeways), I'd prolly be getting at least 29/30 MPG. However, frequent driving near/over the speed limit really makes the MPG nose-dive.

What part of the country are you in, i.e. how cold was it from Feb to June, when you started using the A/C?
 
We all know A/C cuts MPG. My experience says that temps below 50 also cost MPG. So, if you're not in a cold climate, say above 50* from when you got you car until you started using the A/C you were probably driving under better MPG conditions (although you had the break-in period).
 
Reprogramming the speedo will not affect the MPG.

Thanks! Carmax has a loaded one for a great price, I may go drive it to see what it's like.
