Speedo

Did anyone check their speedometer on a 2017 300 against a GPS..? Mine indicated 9 km/h (6,6mph) higher then the GPS...

Yes, pretty much all Lexus speedometers show a little faster than actual speed.

Yup, all speedometers should indicate around 3-4 km/t over to be on the "safe side" but not 9.....

The dealer has the ability to calibrate your speedometer +/- 4 to 6 mph depending on year/model with their scan tool to accomodate tire size variations.
