You may be driving with different size tires from the original size. If you are, then it may change what your speedometer is reading compared to road speed you are actually going. If you have a GPS or use the GPS on your phone, you could also try and do a speed comparison. If you have the correct tire size then you may have a problem with the speedometer or the tachometer. I recommend having a mechanic one come and check the systems for you to verify the problem. If needed, they can replace your speed sensor that your car will have accurate readings.
