I have a 2007 Hyundai Santa Fe with just over 90,000 KMs and recently the fuel gauge started to fluctuate wildly. I had the sensor's replaced and filled the tank and it only showed half full. So one of the new sensors was faulty, so that was replaced and all seemed good. The vehicle worked fine during this time, but I didn't know how much fuel there was. About a month later I was driving up a slight hill and the vehicle stalled. The electric still worked, but the power brakes and steering didn't. I pulled over and the tried to start it and it turned over but didn't start. After 5 minutes I tried again and it was fine. I didn't notice if the fuel gauge was off, but I had filled up a few days before so there was three quarters of a tank of gas. I drove for another 30 minutes without incident. I parked in my driveway and left the car running. When I returned 2 minutes later the car had shut down. My wife said it went to empty and then shut off. I tried the car a few minutes later and it showed empty but started. Then shut off. I tried again and it went back to normal. Then a minute later it went to empty again and died. Electrical was still working. I left the car and tried again a day later and it started and seemed fine. The check engine light was on. I took it to the dealer and they checked the code and it said the fuel sensors were bad again so they replaced them. They didn't thinkn the sensors would lead to the car stalling the way it did.
My wife is now afraid to drive without difinitive proof that the sensors caused the stall. Any ideas?
