The fuel gauge on my car has begun to only work intermittently. Often, after filling my tank, the fuel gauge reads empty. After a while it starts to work again although there doesn’t seem to be a rhyme or reason as to when it will work. Google searches have found this is not an uncommon problem on Santa Fe’s although, curiously, there have been no recalls. Any ideas about how I can get my gauge to work consistently short of replacing the level sender in the fuel tank?
Not curious at all . You are out of warranty and recalls are mostly for safety reasons . Just check with a local shop for a estimate and you don’t need a dealer although they might do it quicker and might not be that much more expensive.

You most likely have deposits on the fuel sending unit
Obviously the most permanent solution is to replace the fuel sending unit
However, there is another path you can take . . . start filling up with top tier gasoline. It might just clean up enough of the deposits to resolve the problem
Costco comes to mind
It fixed the exact same problem on one of my cars . . . completely different brand, for what it’s worth
Thanks so much db4690! I’ll give this a try. Did you also try fuel injector cleaner or any other additives to clean up the deposits?
No, I didn’t
