Can the speedo/odo be calibrated on a 2011 Sonata? Mine are 4% UNDER-reporting, so my already crappy mileage is even worse than I though. Tires are correct size, so that's not the cause. Just so you know, when I drive 100 miles, actual GPS miles is only 96. The dash liar already over-reports my mileage by 1.5 to 3 mpg; the 4% error makes this about 2-4 mpg over-reported.

When I'm on the fwy, I have to set the cruise at about 83 to run 80. I did a check at 100 on the GPS and was running right at 104, indicated.

TIA,
Lyle

the majority of them are off including mine.

You would need Hyundai GDS scan tool or equivalent to access the PCM / cluster. It might or might not support adjustments. some do and some do not.
