earlier yesterday I noticed that my gas "distance until empty" was showing '0' and the was over 1/4 tank during the same time the power fold in mirrors didnt fold in anymore (factory settings will not allow to fold in at a certain MPH) along with the suspension setting of 'Lift' being grayed out as if I were going over 55 but I was stationary. ???

later this evening, I disconncted the battery for about 4 minutes and the problem remained but noticed the "Servtronic Power Steering no longer working, the Air suspension reverted back to the lowest setting even though the car displayed 'Automatic', also noticed the suspension kept adjusting on its own and was not dampering as normal, the transmission was shifting but seem like it wasnt acting normal as far a the electronics go and the speedometer, gas gauge and tachometer is not working properly.

The car starts with no problem, the lights do not seem dim etc. Thanks for any help one may provide.
