The fuel tank level sensor failed and yes can be inspected. Check engine light goes on and fuel says empty with little yellow light .My mechanic checked my car and told me it was the fuel tank level sensor. Check engine light goes on and the fuel needle goes up and down to empty. When I fill the tank, the check engine light goes off and the needle rises to full. When the gas reaches a certain level the check engine light goes on and fuel needle drops to empty . It will go up and down. This first occurred October 2022.

While I was driving along at approximately 25 MPH in my Hyundai santafe the steering became very difficult and there was no throttle response. I stopped the vehicle completely in the middle of the boulevard street and put the vehicle in park and restarted the engine. I was very frightened during the incident that someone was going to run into the back of my car and that the vehicle would stop again before I got home. I refused to drive the vehicle again and followed my husband in another vehicle as he drove the faulty vehicle to the dealer the following day. The tech rep we spoke with at the dealer casually said the throttle positioning sensor was bad and if we wanted it repaired it would cost about $400. I couldn't believe they would let me leave the dealership with this malfunctioning part. The symptoms are the same as the general motors ignition switch problem. …
Late last year (2014) my gas gauge suddenly showed empty (with empty light coming on) on my 2008 Hyundai Santa Fe gls 2..3 l engine. In addition, the 'check engine' came on and stayed on. I took vehicle to my mechanic, who told me the fail codes related to the a and b sensors in the fuel tank not functioning properly. The cost of the repair was estimated at around $700.00. My vehicle is no longer under any warranty. I asked if this defect is causing environmental problems or other problems that could cause engine damage, etc. And he said no. I said well, I could live with this by zeroing out my trip indicator and keeping track that way, knowing my approximate mpg. …
My gas gauge stopped working correctly, going up and down but never passing one half a tank and the check engine light remains on all the time. The mechanic said the seats would need to be taken out to get to the sensor, that it was probably bad and would need a new one. I tried to estimate how much gas I had in the tank by using the odometer and resetting at 0 for a gas fillup till I got the car in for service. The tank would kick the gas back at half a tank so I was getting only 8 gallons in. On Tuesday I ran out of gas on a highway going 55, which was dangerous, as there was a truck behind me and he had to swerve into the median to avoid hitting me when my car died. I was towed to the mechanic. The mechanic checked bytaking the seats out and putting in a new sensor. …
Our gas gauge shows empty, and the fuel light stays on, all the time. This occurs even after we fill the car up. This occurs whether the car is stationary or running. We have to track our fuel level by keeping track of the mileage. Also, if we turn the car off when fueling, it will not turn back on. We have to try over and over again until it turns on. We have found that if we leave the car running while fueling, it usually stays running; however, a lot of times, the car stops running and then, we struggle to get it started again. This is our 2nd Santa Fe (our first was a 2004, with which we never had a problem). If Hyundai doesn't do something to fix this problem, this will be our last Hyundai. …
Over the last year, our Hyundai Santa Fe has developed a very troubling stalling problem that has only increased in frequency. The vehicle loses power while driving regardless of speed, often several times in the same trip regardless of distance traveled. It stalls on local, low-speed roads as well as freeway driving. When it stalls, all steering is lost. This is potentially dangerous. A simple google search indicates that this is a known issue among Hyundai customers and dealerships and yet I am not able to locate any information about a recall to correct this issue. This is a potentially fatal problem that should be addressed by Hyundai. I did contact them. Today, I received a response indicating that Hyundai has no explanation for the issue and will offer no assistance to repair it. Their only suggestion was that I contact a local dealership for repair. …
On a trip this past weekend, I experienced an alarming situation. I was driving 65 MPH on a highway, when the fuel gauge suddenly registered empty after my having filled the tank only 40 miles previously, and the check engine light came on. I immediately exited the highway, stopped, and called the dealership and talked to a mechanic, who said the likely explanation was a faulty fuel sensor. While we were talking, the needle began to rise and fall. When I determined it was not immediately dangerous, I continued my trip. The gauge eventually returned to normal, but the problem reappeared the next time I filled up; again, the gauge eventually began behaving normally, and the check engine light went out. This morning I took the car to the dealership, and they confirmed the faulty fuel sensor. Cost to repair was $612 ' an outrageous amount. …
Fuel gauge not working properly. Goes to empty when I put gas in to fill tank and fuel light comes on. After driving a few miles, needle on gauge fluctuates. Then check engine light comes on. I ran out of gas while trying to enter into traffic on highway and almost got ran over , almost causing a serious accident. Extremely dangerous situation! My mechanic just replaced both fuel sensors on 4/29/2019 as check engine readout indicated. This costly repair did not fix the problem. The fuel gauge still fluctuates, reads empty when filling, fuel light comes on and now check engine light is on again. This is a serious safty proplem and should be recalled by Hyundai. I am afraid now when driving my car because of this. Is Hyundai not recalling because they know even when replaced, the new parts are faulty too? NHTSA, you need to please step in before someone gets seriously hurt or killed. …
