Sonata NF (2006-10) :: 2008 Won't Start After Refilling Tank
Sep 14, 2011
My 2008 Hyundai Sonata wouldn't start on two separate occasions after I had refilled my tank. The first incident happened a little over a month ago (early August 2011), the starter would crank, and crank, but no signs of life in the engine. Tested the spark plugs, I was getting spark, but the sucker wouldn't start. The car was only at about 55k miles when this problem began.
I had the car towed to the dealership, and they said after 4 long attempts, they got it to start. I took it home, and the next morning I couldn't start it again. Towed it back a second time, and it started right up for them. Drove it back home again, and for a little more than a month, the car ran fine, but things started acting up again.
A few days ago the wife pulled the car out of the garage (fyi: my garage is level) stopped the car on our slanted driveway and when she came back to start it just minutes later, it hesitated, but did turn over. I filled up the tank, parked it in my garage and the very next morning, I could not start my car again.
Called for a tow from AAA, and the driver said "let me try something". Pulled out a hammer, and wacked the bottom of my gas tank 4 or 5 times. The tow guy gets in, tuns the ignition to engage the fuel pump (didn't turn the key all the way), he does this about 4 times, then the very next turn of the key it starts right up. The driver said it sounded like a bad fuel pump.
I drive the car back to the dealership (this is the third time) and talk to the same guy I had dealt with all along. He calls me later in the day to tell me they finally got it to not start and were able to isolate the problem to the fuel pump sensor. They replaced the fuel pump assembly and I was off and running.
To summarize:
*Refilling the tank on two separate occasions seemed to be related to the car not starting the following day.
*Towing the car allowed the car to jostle back & forth, which for some reason would allow the dealer to start it when it arrived.
*Was able to start the car by hitting the fuel tank (just underneath it) with a hammer, turning the key 3/4 of the way on a few times, then turning the key all the way.
*Dealer diagnosed bad fuel pump sensor, and replaced fuel pump assembly.

I have an 08 2.4L Sonata with 95000mi. When turning the ignition it will crank and sound like its about to start but won't. I was able to get it to start by pushing the gas pedal a bit when it sounds like it wanted to start. Once started, it ran rough and would stall unless I revved it above 1500 RPM. Still sounded like it occasionally miss fired.
I kept it revved until it reached normal operating temp. When I took my foot slowly off the gas, rpm dropped to about 500-600 and it seemed to pulse . I think engine was raising throttle to keep from stalling. It stalls if I try to put in gear without pressing on gas to raise throttle.
The spark plugs were changed at about 70K mikes. I have not read any codes as the car is stuck in the driveway. Could it be a vacuum leak? I know the Entourages have air intake hose leaks that cause rough idle but with a 6 cyl it still runs. Fuel pump problem?

I have a 2008 2.4L Sonata GLS with 96K mi. It is hard to start and idles rough. I cleaned some components and changed spark plugs. I disconnected the negative battery cable to see if it would reset and relearn settings. Took a 15 mi drive and read codes and P0016 was pending, it was still idling rough and acceleration was still under par. I then cleared the code. I purchased a new cam sensor and compared the Ohm readings between the old and new Cam position sensor. The Ohm readings were different by 50% so I assumed the old was indeed bad.
I installed the new sensor, repeated battery disconnect for 10 min, then restarted engine. It was still idling rough (maybe a little better) so I rechecked for codes. P0016 was still a pending code. I cleared the code and P0016 cam right back. The battery is good (no charging issues), timing chain is original (no noise). Is there a way to test the crank position sensor before buying a new one? I've also seen in posts the Oil Control Valve (OCV) affects timing and seems to be a problem for these vehicles, however I have not received that code (P0011). I can limp it to work but will have to take it in if I cannot solve this soon. If it ends up being a timing chain problem what ballpark price should I expect to pay to have it done.

I drove from office to home today. After 30 min, the remote unlock worked fine, got into the car, turned the ignition to "A" and "ON". All the dashboard lights, headlights and radio turned on. When I turned the key to "START" , car won't start and all the lights and radio turned off. There was no cranking and any other noise from engine. Removed the key and tried again. Now there is no power at all. Not sure what happened.

I'm in a bit of a bind. I was very low on gas drove my car on fumes (mistake, yes) back to my place. Today, it will not start. I dumped 3/4 of a gallon into the tank, and still no start.
The ignition will try, fail to engage the engine, and then emit rapid clicks as the interior light flashes. The battery works, as all the cabin lights turn on.
I really don't want to the fuel pump to be broken, so I'm trying to eliminate possibilities before that. Is there something wrong with the ignition, perhaps? What is the clicking after the attempted "heaves" of the ignition switch?

I have a 2008 Hyundai Sonata that overflows at most gas stations when filling. To fill the tank, I set the pump on autofill and walk away. The pump clicks off and then the car "burps" and gas comes out the filler neck and runs down the outside of the car and out the bottom. It does not do this at one gas station by my house but seems to at all others almost every time. The car is still under warranty (42,000 miles but the issue started at 29,000) and I have brought it to the dealer 3 times. Each time they claim to have found something new wrong and fix. The first time they replaced the fuel filler neck, 2nd time fuel filler neck assembly (and tested at a gas station and it worked), 3rd time the vent valve. Each time I try it and it overflows for me (except at that one gas station). I have never had this issue before with any other car including my wife's current car. I'm truly stumped, but feel that a car should be able to fill up at a gas pump without overflowing.

My 08 2.4l sonata gls won't start. I started it this morning to warm it up while I cleared off all the snow, it was running for about ten minutes. I turned it off and about twenty minute later went to start it and it will not catch. All the electronics are running and the engine turns over but it won't start. I replaced the battery in December, the oil was changed last week as well as the air filter. It has 93k miles on it. What could be the problem? I did go borrow a diagnostic scanner and it is throwing a P2110 P2118 and P2119 code.

Having a problem with the 2008 Sonata GLS. When filling gas tank, pump nozzle clicks off, but gas flow continues, creating a significant spillage.

I've noticed a couple times since I've filled my tank up that it over flows before the gas pump clicks off, this has been at two separate gas stations. I've always put the nozzle back as soon as it clicks off, not one of those retarded people that fill go CLICK CLICK CLICK CLICK CLICK CLICK until it over flow or because they want to round it off. I've never changed that fuel breather filter, or what ever it's called. I didn't think it's needed. 107k here.

Where is the fuel tank air filter located? If you will look in your maint. log or owners manual for the four cyl. under emmissions control you will find the fuel tank air filter to be inspected at 15000 miles and changed at 30000 miles.

So I fill up my 2007 Sonata for the very first time. I'm squeezing the trigger on the pump, it clicks off automatically when it senses it's full, then about a pint of gas backs up out of the tank and onto the floor. Is there some sort of design flaw on the Sonata that causes this to happen? It could have been a problem with the pump, but I don't usually have that happen with my other cars.

I am looking for an answer to changing my 2007 Sonata fuel tank air filter that is mentioned in my 30,000 mile maintenance schedule. Is this an easy change or does my car have to be taken to the dealer for this?

I have a 2009 Sonata SE 3.3 with about 35,000miles. I am the second owner.
I believe that my gas gauge or the sending unit in the tank is bad. The gauge will show empty when the tank has fuel and then it will sometimes read normal.

I have a 09 sonata NF. The gas pump continually clicks off while filling the tank. I saw this issue discussed here before but I cannot find it. Has to do with a vapor canister and valve?

So I have a little weird issue. My car has been sputtering a little when sitting idle at lights and such. But once I fill it up with gas the sputtering is even more noticeable. What this is?

My wife's 2007 Accent started having starting problems right after filling the tank. Is this an EVAP canister problem?

It seems that I'm having issues with playing my IPod through my stereo on my '09 Sonata. I'm using the factory radio with the IPod connection in the console. I bought the cable from EBay. Sometimes the IPod will just pause and stop playing. Sometimes I have to unplug it and plug it back in to get it to work, other times I can just switch sources and switch back and it will work again. Also, isn't it supposed to charge the IPod also? I have left it for overnight a few times without unplugging it and when I came back in the morning, it would not play because it was dead. It did not even start to charge once I started the car up.

All of the sudden it's not going into D, instead wants to manually be driven and having to downshift instead of upshift... so weird. It' erratic. Would it be a sensor, or internal issue with the transmission? Or shifter just sticking?

I have an '08 GLS and I've been hearing a "pop" noise coming from the rear passenger wheel well when I am braking. It only happens once per braking episode and usually if I am applying medium brake pressure, i.e. slowing from >25 mph. What this might be and is it normal?

I have a Sonata 2008 model which has done only 40K miles so far. All of a sudden i got the engine management light on and i scanned it in the garage. They are saying the fault is with EGR Valve and it needs to be replaced. They reset it and now the light is not ON.
Could it just be a glitch or is it really a problem with EGR valve. I am really confused on what to do, because when i got a second opinion from a local garage they said there is no need to replace - simply a clean would do....
2 days after the engine light reset, when i took the car off the park i suddenly got a grinding noise from the front of the car and i switched if off and re-started and the noise went away..not sure whether this could be linked with EGR valve or was it a simple gear slip.
