Other Fuel System Tank Filling/charging problems of the 2007 Hyundai Santa Fe

Fuel gage always changes levels. Constantly making the low gas light to turn on even after filling the gas tank up at the gas station. Its very dangerous to not know where you gas level is when many use the Santa Fe as their family car to transport their children. Its been happening the past week.

The gas sensor is malfunctioning. Cause the tank to show out of gas when there is at least a half a tank in it. This has also caused the check engine light to come on and off whenever it wants to. I would travel to get it check only for the light to be off. I am unable to safely drive with out filling up my tank every couple of day to ensure that I actually have gas. It is causing the car to be slow in starting after a light or when trying to merge with traffic, hitting the gas does not really do much. It's a danger on the road. In doing a quick google search while trying to determine what the issue might be - it seems this is a wide spread and known Hyundai problem that hasn't been addressed becuase there has not been a loss of life. It shouldn't have ot get that far to prevent what is an obvious and widespread issue.

Faulty gas gauge. After filling up to a full gas tank, gas gauge will go up and down and eventually stop at an incorrect reading. This happens whether the vehicle is stationary or in motion. I never know how much gas I have which is incredibly unsafe and dangerous!!! when the gauge gets below half a tank, the check engine light will come on. This has been happening for months and now the check engine light will not turn off at all no matter how much gas the car has. Then, car started to smell like gas inside when driving on the highway. Took to Hyundai dealership to fix and was quoted over $1,000. This vehicle should be recalled, the gas gauge issue is a safety issue because someone could run out of gas and be stranded.

Leaving my home to travel out of town, the engine light came on. After having a diagnostic test completed I was told the sensors in the gas tank are malfunctioning (p0464) and this is a known issue with 2007 Hyundai sante fe models. The gauge telling me how much gas I have is not reading correctly due to the sensor malfunction and can cause me to run out of gas at any time. The dealer refuses to do anything about it without charging me a $98 "diagnostic fee" even though the diagnostic was done elsewhere. I have an extended warranty on this vehicle but they refuse to honor that as well.

The fuel level gauge changes randomly. Check engines codes p0463, p0464, p2068 indicates a fuel level sensor failure. This is issue has occurred on other car manufacturers potentially using the same sensor system. There have been no recalls issued for this problem. The owner will not be able to know the accurate fuel level of the vehicle. This may cause tank overfilling and potentially safety and environmental issues. This is very expensive to repair ($1000) and is not covered by Hyundai after the 5 year warranty.

Faulty fuel gage. The fuel gage will register empty and the fuel light will come on after filling up the tank. The gage will waver and give faulty registers while driving, even climbing back to full after registering "empty" seconds before.

A day after filling my tank the gauge read empty. I tried filling it up again and it need only about two gallons before overflowing. A few months later, when I took the car for an oil change, they said there was no problem. I did explain that the tank release and the gas gauge was not working (I believe that when I visited the dealer and told them about the check-engine light they knew what the problem was. They reset the light but the problem persisted. This happened prior to the 5 years warrant expiration). It got progressively worse and when I went in April of this year, I was told that I needed to fuel senders @ a cost of $about $450. 00 inclusive. The gauge was not working prior to the 5 year expiration and the dealer said that and the tank release were fine. The automobile has a problem just about everyone who owns a 2007 Santa Fee has a fuel system problem. Please look into this problem and protect consumers from this type of problem.
