2005 Chevy Impala crazy guages

Thanks for your last reply. My gas, mph and temperature guages are screwy. Mph sometimes does not reset to 0 when I turn the car off. The needle may stick on 40 so when I go 30 it reads 70. When it does reset it appears to give the correct reading. Gas tank guage reads empty when it is full, temp guage may read way beyond the hottest point and the car is running normal. Also the "message box" gives me faulty indicators like low windshield washer fluid, or low brake fluid. These things are not low and the message box does not read these all the time. Thanks for your help.
