The Instrument Cluster Freezes and has to be reset. When it freezes you have not knowledge of speed you are going. After bringing it into Tesla Service I was told that is a known defect. The only way to fix is to replace Infotainment system at a cost of $2,100. Infotainment system currently works fine. The rep informed me that the system does not have enough memory to run the computer correctly after all the updates that Tesla Makes you install.
