Stephen Foenander Posted September 16, 2009 Share Posted September 16, 2009 I just returned from interstate after driving my is250 over 1200 kms and worked out from using my navman that my speedometer is out by 10km per hour. At 60km/h the car is doing 50 at 110 km/h it is doing 100 km/h etc. Took it in to the Lexus dealer and they said there is nothing they can do. I am of the opinion that for such a great car with excellent build quality this is just not good enough. Does anybody know if there is a fix for this problem that has been documented by others before me. I shouldn't have to drive at 70 to be doing a real 60. This is also adding extra mileage to my vehicle over long periods. The dealer said they could check the car to determine how innacurate the speedo is but not fix it. UNACCEPTABLE.....
