Replaced the 12V battery 2 weeks ago and now I have a whining noise in the cabin when moving on the road that was not there previously. t was very quiet and never knew when it switched between the electric to gas motor.  The noise, as an example only, when an ordinary car transmission is accelerating but does not drop to the next gear, noise just keep on going higher. Anyone else have this problem?
