2012 SE speedometer off

[Blue Minnow]

Has any-one else checked their speedometer? When I am going 65mph on the speedometer my GPS say 61, and i have checked it on 2 GPS's and have run those 2 GPS's on 2 other cars. So its definatly off. I am thinking my odometer is off too possibly. I am going to have it looked at soon under warranty. I am wondering if they can re-adjust the odemeter if it is off. i think they should set it back. i think i am showing about 600 miles to much right now. losing warranty fast here. I think the tires on the SE must be a little smaller than the other models, and they didn't adjust the speedometer for it.

We have a few radar signs which say "Your speed is." I've noticed they report 5% less than my speedometer. I.e., speedometer says 42 and the sign says 40.

Good point about this working in Hyundai's favor. Maybe it's why the dashboard MPG is off by 5% too.

But, I wonder how perfect any speedo can be. I wonder if 5% is within the margin of error.

There are advantages to erring on the side of overstatement. If I push the posted speed limit to 50, I should have a greater chance of a police officer recording me doing 47.5. Not enough over the 45 limit to be cited. But, if the speedo understated 5%, I would be doing 55 instead of 50, which would definitely result in a citation.

Might be worthwhile to leave well enough alone?

So I figured out that I am getting 2 miles a gallon less than I thought I was too. I think the Koreans are a bunch of Crooks. My 60K warranty will be up 5500 miles sooner too. I probably would not have bought this car if I had known all this sooner. Still like the car, but I bought this car based on the 40 mpg hwy sticker. Now i have to go check the KIA we just bought.

I just found this online. gonna try it tomorrow using a GPS for the 2 mile distance.

Electronic Speedometer calibration made easy!

To calibrate your electronic speedometer:
1) With the power off, push and hold the calibration button (trip/reset button when equipped). While holding the button, start the vehicle and continue to hold the button until the pointer sweeps to full scale and stays at full scale. You may now release the button.
2) Drive to the beginning of a pre-marked 2 mile distance and come to a stop. It does not matter how far away it is to get to this pre-marked 2 mile distance. Do NOT shut the engine off. Push and release the button. The pointer will drop to half scale.
3) Drive the 2 mile distance. The pointer will remain at the half scale mark no matter what speed you drive. If the speedometer has a LCD display odometer, it will be normal to see it counting rapidly as it is receiving a speed signal. If you have to stop during the calibration, that is o.k.. The speedometer is simply counting pulses during this time.
4) At the end of the 2 mile distance, come to a complete stop and push and release the button. The pointer will drop to 0 and the calibration is stored. You are now finished.
Remember the accuracy of your 2 mile distance will directly affect the accuracy of your speedometer.

Do you have Autometer gauges installed in your car? I dont foresee this working with Hyundai factory guages...

Read it! The manual gives you the speedometer specs and let's you know that the speedometer can not be adjusted.

Most cars are set a few mph higher. If they were set lower than actual and I got a ticket...........I would be pissed off!

My speedo reads a couple of MPH low as well.. When the speedo is showing 63, the GPS shows 60. (I've checked the speedo with three different GPS units and the results have all been the same).

FWIW, I've checked my odometer using accurately spaced highway markers and found that it 2% low... So, if my odometer says 100 miles, I've really gone 102. I apply that 2% correction when I hand calculate my mileage. It doesn't make that much of a difference. (Less than 1 MPG).
