Has anyone else had issues with the external temp gauge on the instrument cluster? Mine works mostly, but will often fail to show the correct temp. For instance, it will be 35 degrees outside and my car will show an accurate 61 degrees when started in the garage. While driving, it will drop to about 58 degrees after a couple of minutes. When I get to work, which is about a 20 minute drive, it will have dropped to maybe 45 degrees and hold that for the last 10 minutes. I'm wondering if I may have a bad sensor in the system.
