Hyundai Sonata Problem Report
Hyundai Sonata false temp gauge reading or electrical problem - check engine grounds
I had my car to many mechanics and replaced many parts when my temp gauge kept reading hot, but it actually wasn't. A master tech finally listened to me and went directly to the problem. The manufacturer had not installed one of my ground wires to the engine. That explains why I kept going through batteries and headlight bulbs. Finally the issue got to my temp gauge and my window motor. Not having that ground, my car was handling it in other ways all these years. Of course Hyandai wouldn't reimburse my expenses. - Cricket777
