My battery kept dying due to corrosion. We replaced the positive cable, and that is when random stuff started happening. The 4 dash button to the right of steering wheel stopped working correctly. They would toggle random stuff on dash for a split second but nothing could be changed. (No average speed, instant speed, tire pressure, fuel range, etc.) Then the car started saying we had low tire pressure (tire pressure was fine) so we had all four sensors replaced.

The low tire pressure light still comes on (again - tire pressure is fine). Now the dash is telling us our air bags need servicing. I believe these issues are all stemming from the same electrical issues caused by the original corrosion. Still looking for a fix.
