I recently had to replace the front brake pads and a wheel bearing on the driver's side. Ever since I can be driving along and all the warning lights on the dash come on and all the gauges quit working except for the speedometer and the RPM gauge.
I have cleaned all the ground wires and she worked fine for a few days but is doing it again. It doesn't affect the fuel pump as you can keep on driving. One other thing is you have to lock or unlock the doors manually.
