THE FACTORY PROGRAMMING OF THE COMPUTER AND SPEED CONTROL IS INCORRECT. PORSCHE STATES THAT THE VEHICLE IS OPERATING WITHIN CHARACTERISTICS AND SPECIFICATIONS [AND ACCORDING TO US LAW A VARIANCE OF UP TO 18% IS ALLOWED IN THE SPEEDOMETER.] HOWEVER, PORSCHE HAS TAKEN THE US LAW TO MEAN THAT IT IS ALLOWED TO INTENTIONALLY PROGRAM ITS COMPUTERS TO THE SAME SPECIFICATIONS AS ANALOG GAUGES. PORSCHE CANNOT DEMONSTRATE THAT THE INACCURACY IN THE SPEEDOMETER IS NOT EFFECTING THE HYBRID OPERATIONS OF THE VEHICLE. THE INACCURATE SPEED READING MAY ALSO CREATE INACCURATE ODOMETER READINGS. IN ADDITION THE VEHICLE HAS PROBLEMS WITH HARD BRAKING WHICH IS ESPECIALLY PRONOUNCED WHEN THE VEHICLE IS UNDER CRUISE CONTROL. AND IN CERTAIN INSTANCES THERE IS LAG ON ACCELERATION. PORSCHE HAS REFUSED TO REPROGRAM THE SPEEDOMETER CONTROLS TO ACTUAL SPEED. GIVEN THAT THE ONLY PROBLEMS ON THE VEHICLE ARE RELATED TO THE SPEED OF THE VEHICLE, IT SEEMS THAT PORSCHE SHOULD BE CAPABLE OF PROVIDING A SOLUTION BY REPROGRAMMING THE ONBOARD COMPUTERS. *TT
