2009 Hyundai Santa Fe Stalls out/DEATH TRAP, occasionally with no warning, seem to be when going up or down hills usually with quarter tank of gas approx. Possibly when decelerating. We have replaced both fuel pumps and it was ok for a while. The other day I was going down steep hill and it quit, i coasted to bottom and tried at least 10 times to restart. A DEATH TRAP for people, i had cars flying up on me almost rear ending me even thou I had my emergency flashers were on and my arm out the window flagging then around. I let car sit still a few minutes and it finally cracked. I started looking online for solutions but found many 2009 Santa Fe's have this problem. I called Hyundai and no Recall. I have already spend over $500 trying to repair this. I do see settlement against Hyundai for this problem on other years. They seem to know it is a problem but are not fixing unless forced. …
My kids and I were going to town one afternoon and I started to smell gas coming from the air vents the gas smell was very strong I opened the hood and could see that it was wet I touched the spot and smelled it and it was fuel.i was worried about driving home with my children in the car so I called my brother he came looked and tracked down the issue and the fuel leak was coming from the front fuel rail.i had never heard of a fuel rail going out on a vehicle before so calling around to parts stores and auto parts recycling places to get it fixed and no one will sale me one they have all told me to take it to dealership.please help it's the only vehicle my children and i have.
I was decelarating after going highway speed on the highway and the car stalled electrical still worked but braking power steering acceleation all stopped working and engine lights turned on and esc and other lights i retarted the car and no engine lights turned on i went to my mechanic he said it dosnt show on diagnostics so he cant fix it this is just one incident its happend numerous times and it almost caused accident its dangerous and must be dealt with right away
The vehicle's check engine light came on and the fuel gauge shows "E". I did an OBD scan and it shows the fuel sending unit has issues. The gauge will work intermittently and the check engine light will go away. Further reviews from others show the same issues with their vehicle with each needing a bad sending unit replaced.
Airbag light continuously on. Never had a problem before. Have been in an accident but cleared. Car was put back together and not on a salvage title. Fuel pump sensors are at fault. Need to replace fuel pump sensors. All fault codes appear when vehicle is not in motion.
Pulling into driveway. Car engine accelerated suddenly. Was just coasting in. The car wouldn't stop. Hit front of a home. The engine sounded like a race car.
I've taken my 2009 Santa Fe to the rick case roswell, ga on Friday, 7/1/2016 and again today, 7/15/2016, both for the same issue, my car is stalling while I drive it. On 7/1 they told me it was the battery, so had a new one installed while there. Both times, I'm been turning into a curve (it was a right hand turn on 7/1 and a left hand turn on 7/15). The first time I was lucky as it was just coming off a stop light. Last night, however, it was a curve to get on the highway with an 18 wheeler thundering behind me when my car stalled, and I lost the power steering and braking and almost became an 18 wheeler hood ornament. As I mentioned, the dealer is perplexed by the issue, nothing is showing up on the diagnostics and they can't replicate the problem. I had to leave the dealership with the sense that I'm driving around in a ticking time bomb. …
Starting on July 15, 2016, the check engine light (MIL) came on, as well the fuel gauge incorrectly indicating the amount of fuel, in the fuel tank, at 107130 miles. I had the MIL diagnosed as p0464, fuel sensor defect. Many other Hyundai Santa Fe owners, have reported this problem, requesting financial assistance to repair this significant safety problem, to Hyundai customer service, to no avail. Their response has been it is not their concern and have not offered to provide financial assistance. If I were to be driving at highway speed, e.g., 55-75 MPH, and have the engine shut down, due to lack of fuel, the power steering would be significantly impaired, with loss of control. …
My gas gage started to work improperly. I took it to a mechanic I trust. He told me the fuel pump senders were bad. After he removed them he called me to tell me I was lucky my vehicle didn't catch fire or blow up! One sender has insulation broken and the wire is exposed. He also found that an internal wire was even worst. The protective connector was gone! That left those wires with no protection. They show signs of bad corrosion on both the wires and the terminals. They appear to maybe even have shorted out. They are black and a rust orange color. They are also pitted. I contacted Hyundai. They didn't seem to care. They were more concerned that I hadn't brought my car to a dealer for over five years. I explained that two different dealerships here in miami had cheated me and treated me badly. …
"Takata recall" my 2009 Hyundai Santa Fe, at approximately 110 miles, developed a problem, which actually results in a serious/safety problem. The problem is with the fuel system fuel gauge displaying the correct amount of fuel available in the tank. I don't know if the problem is with the fuel pumps, or the fuel sensing units in the gas tanks, or with the wiring between the gas tank and the gas gauge, or with the gas gauge itself. It doesn't matter if the vehicle is stationary or moving nor if the vehicle is slanted at an angle. Quite often the problem results in the "check engine" light coming on. So far I've only run out of gas once, and since I was on the freeway this was a very serious safety issue as I lost both my steering and braking systems. Any more I stop for fuel after about 120 miles or so. …
