Sedans Hyundai Elantra 2007 Elantra Speedometer / Odometer

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.

Replying to: ebbuts (Oct 05, 2007 8:56 am) 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.

Replying to: he07drivr (Oct 06, 2007 3:17 pm) 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? |

Replying to: he07drivr (Oct 06, 2007 3:17 pm) 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. |

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.

| 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. | |
