    Speedometer - Odometer Recalibration.

    I won't retype the whole letter but it says automatic equipped Elantras made thru 5/28/07 MAY indicate fasters speeds and more miles than actual.

    They are asking us to take our car to the dealer (call for appt)and they will reprogram the Electronic Control Unit at no charge.

    They will also extend the mileage period of all warranties provided with your vehicle by 3%(in red)

    If you have any difficulty getting this recal performed call 1-800-633-5151

    Personally I tested my speedometer with another car when I test drove my car, and it was spot on with the other car, but I may check it anyway, since maybe it changed when car was breaking in.

    Chronicles of a Hyundai Owner

  • I received the letter yesterday and went to the dealer today. They reprogrammed it with no hassle. :shades: This is an 07 Elantra SE built in November 2006.

    I asked about their criteria and was told by the service writer that they check the car's computer for the existence of a particular code (I'm not sure which) and if it's set to one of the values they're aware of as problematic, then they perform the work specified in the TSB. So, if your car has the problem and the dealer is refusing, then maybe some sort of 2-car road test would help.

    Also, the dealer does not handle the warranty extension. You still have to call HMA and get that updated through them. I'll be starting that process this week.

    If it's of any value, I can post the service order line item for the TSB work.

  • I received the letter from Hyundai yesterday saying they are recalling all 2007 Elantras since they all have the problem. If you have not received the letter, contact your dealer and schedule an appointment to recalibrate your speedometer and odometer. You'll put a ton of unneccesary extra miles in the car which will shorten your warranty.
  • 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.
  • Great point. Members with fixed speedos... what's your mpg?

    " 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"

    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.

    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.
  • ebbutsebbuts Posts: 20
    Yes programming will effect the MPG. Why do you think Hyundai gave you some extra mileage on the warranty? Simply because before programming you were getting more miles on your car than after re-programming. So with more miles wouldn't your MPG be greater? Just common sense.
  • bhmr59bhmr59 Posts: 1,598
    Sorry, I should have said the actual MPG. I can see how it appeared I was talking about calculated MPG.

    However, you're talking about an MPG reduction of probably 5 to 10%. Yet the warranty increase is only 3%.

    Something doesn't add up. If your odometer was registering 3% higher and you drove 100 miles, the odo would read 103. Project that to 300 or 309 miles. Assuming a 10 gallon fill-up, you'd be looking at a .9, not 2 or 3 MPG difference. A/C usage will account for some of the difference, temperature range will also.
  • I apologize in my original post about the "demanding" part. I was getting a bit angry. When I was shopping for cars, I was basing my purchasing decision heavily on price, MPG (according to the posted info online and on those info sheets they place in the window), warranty, and size/comfort inside [in that order]. So that being considered, are the MPG estimates that were posted online and on those car information sheets still accurate in estimated MPG? If they were to run those exact tests on the exact car again, only after the re-calibration, would the results still be 28 MPG city, 35 MPG highway? Because if that is NOT true, that is false advertising and depending on how much lower those estimate were, that may have effected my purchasing decision.

    My current calculated mpg is roughly 28 mpg (during non-ethanol gas months). I drive about 40% city, 60% highway with the A/C on in moderate/mild temperatures. After I get my car re-calibrated, I'll post my new calculated mpg.

    Oh, and here is another thing; When they re-calibrate the car, do they modify the odometer to reflect what the mileage should have truly been? Because I am close to qualifying for an insurance discount for driving under 10,000 miles/year, and missing out on that because the car was over-reporting mileage is going to irritate me.
  • nthenthe Posts: 414
    the testing standards the EPA uses is based on human calculations, not on the trip computer.

    Also, the MPG on the window stickers is based on EPA numbers, so no, its not false advertising, cause they aren't hyundai numbers.

    No, they don't modify the odometer. Hyundai has extended the warranty 3%, and 3% of 10000 miles is only 300 miles, so you should not worry. Besides, what does your insurance company do, come out and check you mileage every year?
  • nthenthe Posts: 414
    One other not, the EPA has changed their testing standards to get a more accurate MPG for cars (such as testing at 75 mph, testing with the ac running, higher accel rates, and so on), the the new 08 tests show 25 MPG city and 33 MPG highway for the elantra automatic.

    Again, you have to understand that these numbers are just averages, and unless you drive exactly as the test drive did, then you may not get these results. The EPA does these test to give you a range of what you SHOULD expect, not what you will ACTUALLY get.
  • ebbutsebbuts Posts: 20
    About the insurance mileage discount. I agree with the other replier when he asked if the insurance company comes out to check the odometer. In my many many years they have not and I doubt they ever will. You can give them an annual mileage total of whatever you want. If they know you are a salesman and drive lots of miles and you put down 10000, the agent might question you. Myself, I get old people discount, list low miles, but if I take an extended trip or two a year I am way past what I list. I am not worried about such a trivial thing and doubt the rate difference is that much. About EPA mileage on the window sticker, my car still falls in the average and that is good. Guess I am still more interested in the long term warranty for now.
  • Sorry, I'm confused. If "actual" MPG is based on odometer(unreprogramed) reading, aren't we creating the same error?

    We had ours reprogrammed last week; haven't confirmed speedo or odometer yet but apparent(oh gosh am I really going 80 MPH?) speed is more real.
  • harlqnharlqn Posts: 18
    Do they note the mileage when you make a claim? If that's the case, they may check the mileage at the time the ins. policy started and do the math. Not sure if they'd bother even then, though.

  • Does anyone know if the letter that Hyundai sent out regarding this is posted anywhere online? The only thing I can find is regarding the speedometer not the odometer. Please help as I am fighting with my dealership about this.
  • Anyway you can send me a copy of the letter? I can't find mine and I want the actual letter. Thanks!
  • FYI... I don't know if you are aware, but I just got off the phone with my service department who informed me that when they fix the problem, the attach a sticker to your vehicle stating that the mileage is incorrect. This information will go on the title of the vehicle.
    I don't know about anyone else, but I wouldn't buy a car if the mileage isn't correct. They need to recall the car and replace them with one that doesn't have incorrect mileage. I see a lawsuit in the future about this!

    The reprogramming of the ECM corrects the problem (both speedometer and odometer) from today forward. That is why Hyundai extended the mileage part of the warranty. The only time they put a mileage sticker on your car is when they replace the instrument cluster.
  • Did you get any info on the original letter? I was cited for speeding and need to bring that letter to traffic court and I lost it somehow.
  • nthenthe Posts: 414
    the problem with the speedo was that it was showing a faster speed than you were actually traveling. so if your speedo said you were going 50, your actual speed was about 45. i haven't heard of anyone have a problem of the speedo showing too slow of a speed.
  • ebbutsebbuts Posts: 20
    It would appear to me you don't have much of a leg to stand on because like nthe stated the speedometer is slow not fast so if you are on the interstate doing 85 mph and the speed limit is 75 like ours and you meet up with a ticket happy cop you probably got a ticket for 5 over. If you are going more than that, it's your tough luck. That letter isn't going to do a bit of good in your case I don't think. Pay the ticket and slow down.
  • mike91326mike91326 SoCalPosts: 245
    Or to add insult to injury, the judge will say “So you state you were doing 85 and the cop only wrote you for 75? Well then, let’s tack another $200 on that fine.”
  • harlqnharlqn Posts: 18
    Sorry, I haven't been on this forum in a long time. If you still need the letter, I can probably dig it up.
