Gas gage indication shows empty when the tank is full or empty. This happened with our 2008 Santa Fe too.
About 6 to 9 months after purchasing Santa Fe car stalled while driving down road with 1/4 tank of gas indicated. Gas was put in car and driven to dealership with car stalling a second time in route. Dealer said it was a faulty fuel sensor and it was replaced under warranty. Car stalled on interstate while going 70mph 3/2013 with 1/3 tank of gas showing. Upon adding gas car ran again. Waited a few months until car stalled again while driving around town with "plenty of gas. " took it to dealership 7/2013 and they said it was a fluke and the fuel sensor was replaced again. Once again, 12/2013 car stalled on highway while traveling at 65 while gauge indicated 1/3 tank of gas. Filled with gas and car ran. Took it to dealer 12/2013 and they said it was just a fluke (seems to be party line) but this time they said the float in the fuel tank was getting hung up on something so was giving a false reading. Dealer said hose that got caught on float had been reconnected and should not cause any further problems. Driving around town two days ago with 1/4 tank of gas car stalled again. Have added gas but it is sputtering. Assume it will be another fluke!.
