Hyundai Santa Fe Fuel and Fuel System Questions

brownrtbrownrt Posts: 3
I have a 2002, 6 cylinder Santa Fe with 120,000 miles. It generally runs great. Thee only problem I have is after I fill the car with gas, it is difficult to get the car started, and it runs rough for the next minute or so. Has anyone heard of or had this problem? What is the fix?


  • We experienced the same problem with our 2003 Santa Fe this morning. Until now we have not had any problems. When we gassed up the car it would not start and even after it did the transmission would not shift out of park for a few minutes. This happened to us twice today. Our car has 112,000 miles. Sounds like a very similar problem. What did you find out and has it been fixed? If you have and don't mind what did the dealer charge if you took it back to him?

    This happened to us twice today.

    I am assuming you didn't fill up twice today. If that is the case, on the second try (without the fillup) were you restarting after recently having turned the engine off? I'm wondering if it could be a problem with your injectors.

    I have not had the problem fixed yet. A mechanic suspects a clogged gas tank filter. Problem is, it looks like the entire gas tank has to be removed to get to it, and it is not a sure bet that that fixes it.
  • I have a 2002 Santa Fe (6 cyl) with only about 35,000 miles on it and this identical problem just started for me about six months ago. Maybe it is a fuel filter. I have to admit I do run the fuel level down too far (same money used to keep it a lot fuller!) Anyway, does anybody else notice a correlation between the problem and letting the tank get low? I'm not sure if the two are connected, and I'm still not sure why if it is the fuel filter, why does it clear up? I know that many cars these days have pressurized fuel tanks. I wonder if the problem may have something to do with taking the cap off and depressurizing the tank... I say this because I can shut the car off a few miles later, wait a few minutes and it starts right back up. The only difference I can see is that I didn't remove the fuel cap. Any ideas on this?
  • brownrtbrownrt Posts: 3
    I do not think it is a pressure problem. If I only put $5 of gas in to a fairly empty tank, the car starts as normal. If I fill up past 1/2 tank, the problem happens. It seems like air or vapor must somehow be trapped in to the fuel line.
  • Sounds like the emissions evaporation system could be clogged? Charchol cannister might be soaked or otherwise bad? I am reaching here, but it might be worth a shot.

    Also it's possible you have a bad gas cap that is not properly venting. Are you putting it on tightly enough to click it at least three times after fill up.
  • Not a bad idea. Let's see... if it were the emissions evaporation system, why do we only get the problem at gas stations when restarting? ALL my other restarts are perfectly normal, including first thing in the morning, when the engine is cold (like after work) and after the engine has warmed fully (like stopping at a convenience store after driving for awhile, etc.)

    The ONLY time it happens (at least for me) is gas station restarts and the only thing that's different about them is that I've removed the gas cap. I'm in New Jersey and when we go through inspection, they specifically vacuum test your gas cap (I didn't even know they did this until I failed last year for a bad gas cap on another car). I'm guessing that certain cars are designed to have "sealed" (non-venting caps) and vice versa. I'm not sure which we have, though I would think that the point of an emissions evaporative system would be to NOT let the gas vapors escape out the cap, but rather to force them to vent into a charcoal canister and then get sucked back into the intake air stream somehow later (like my old GMs did). I can't quite figure out why a vented cap would be a good thing, but there are a lot of them out there, so there must be a good reason for them. In any event, I still say it's coincidental that the problem only happens when the gas cap is disturbed- everything else (including the charcoal canister, injectors, fuel filter, etc.) doesn't change during my "non-gas-station" start-ups.

    Since it's cheap enough to test (I would hope), I'll try another gas cap and let you know if it does anything.

    Keep me posted on your progress and thanks for your input!

  • I have a 2003 Santa Fe and have the exact same problem as everyone else seems to have.

    I too have not brought it in for service yet. I realize this thread hasn't been updated in several months, but I was hoping somebody has something new to add.

    All I can add is two things to do in the meantime:

    1. When you start the car after gassing up, give it a lot of gas. The car will rev up and after a few seconds, throw it into drive. If you have enough room to go for a while without stopping, it should be ok. I've been filling up late at night when the stations aren't crowded to do this.

    2. Leave the car running while you gas up. Obviously this is something you're not supposd to do, but it can work. The first time I did it, the car did sputter out and die while gassing up. But I tried it again recently and the car stayed running and I was able to drive off without a problem.
  • Well I finally broke down and brought the car to the dealer over this problem. I'm picking it up tonight, but he told me he replaced the Purge Control Valve. He seemed to jump on this as soon as he heard the problem. Good News: it was covered under the warranty (bumper-to-bumper, I believe, so you better check it out before 60,000 miles... actually I think it might be 50,000 miles depending on your year- the 2002s got a class action settlement for the brochure misstating the horsepower & we got the option of an extra 10,000 on the bumper-to-bumper... bottom line is try to beat the clock and it should be covered. After I pick the car up, I'll let you know if it actually worked...
  • P.S.- I laughed when I read mrubin's post because those were the 2 fixes I have to use also (either leaving the engine on or doing an NHRA smoky burnout out of the gas stations! ...ha!
  • I just want to say thank you to all of you wonderful, helpful people! I just purchased a 2001 Hyundai Sonata with the EXACT same problem at gas stations. Just reading that I am not the only one with the problem makes me feel better but all of the suggestions about ways to fix it is putting me on the right track to solving my problem. THANKS AGAIN!!! =)
  • PROBLEM SOLVED!!! Well, I hope everyone has the same luck, but after the dealer replaced the purge control valve, the car was as good as new... the trouble starting after filling up was completely eliminated immediately afterward. If you do decide to try the same fix, my receipt head the following entry as to what was done: "replaced purge control valve with ECU reset as not allowing purge." Good luck to all!
  • I have an 06 Sonata, and my problem isn't at gas stations, but hitting accelerator after cold start. I get a bucking/ almost misfiring picture. The dealer can't find anything wrong of course. Any ideas? Purge control valve here too? Fuel filter? Injectors?
  • I have a 2002 V6 GLS Sonata. Just recently the car requires numerous attempts to start after I fill up. Once the car has been started the problem disappears until the next refill. I usually fill up at 3/4 empty. Is this fault a poor fitting gas cap or as I have read a Purge Control Valve. The garage "fixed" my car by replacing plug leads and spark plugs as part of an engine tune up. Needless to say the fault reappeared as soon as the next fill up. The garage is now saying it could be a "weak: fuel pump and maybe it needs replacing. In order not to rack up costs on unrequired replacement parts I would appreciate some advice. Thank you.

    it probably is the purge control valve - have you ever overfilled with gas? topping off? that could damage the evap controls... there is a component that catches gas vapors - if you overfill by topping off - you could get raw fuel into that section that should only be getting vapors - this will set off all kinds of related svc eng light codes...
  • I had this same problem on my 2004 Santa Fe. The valve is covered by the 6 year/60,000 warranty, but not the longer powertrain warranty.

    Unfortunately, my Santa Fe has over 60,000 so the repair was 250 dollars. The part is only 36 dollars - the rest labor.

    I urge everyone to go get their valve replaced now while their car is under warranty.
  • somedai1somedai1 Posts: 416
    everyone should try to get a decarb or fuel system cleaning at intervals to keep from getting problems with clogged valvs and injectors.... every 15k miles is good...

    I have a 2006 santa fe and I sem to be using a 1/4 tank on a five mile drive. I have noticed that my rpms shoot up as if extra fuel is being used and then it levels off. I do have an odor of gas at times when parking after driving or starting. When the rpms shoot up and then down the car bucks. Also My check engine light comes on sometimes but not every time. Any suggestions
