I doubt if it has anything to do with the fuel injection. My car did this with less than 5,000 miles. The surest fix I've read about on this forum is to park it and rev the accelerator pedal pretty fast a few times. That's what I did when it happened to me and it fixed it. Mine has only done it one time, but many people on this forum have written about it happening many times. Be sure to call the Hyundai Customer Service line, as we have agreed to do that so at least Hyundai recognizes that a problem exists for which there does not seem to be a cure.
 
I'm a believer in Hyundai, but I don't like it very much when they say they "can't duplicate the problem."

I truly wish I hadn't traded in my 1999 Sonata for this car (Purchased in 9/1999 and traded in 11/2000). I did it on an impulse when taking the Sonata in for it's 9k oil change.
 
I tend to 'baby' any car I own on the required maintenance (and tend to keep a car I like for a long time), so I didn't own the '99' Sonata long enough to know what I kind of record it would have.
 
Nonetheless, I've now owned the '01' XG for long enough to know that Hyundai's promise of quality and extended warranties are all bogus. I have had most of the problems described on this forum, some of which were easy fixes, others not.
 
At the end of the day (because I don't have long commutes), my car has 56k on it, has stranded me twice, alternator replaced, belts replaced (which the dealer said were not covered under the engine and bumper-to-bumper warranties -- and I have the Hyundai Protection Plan also), and I still get random problems. The car runs, but service engine light turns on/stays on most of the time (but the dealership can't replicate it), air bag light is on constantly. In any case, the dealership I bought the car from with always tries to rip you off on maintenance and repairs whenever you go in there.
 
Before I ever had a Hyundai, I had an '81' VW Rabbit Diesel which was fantastic enginewise and probably drove until all the parts had fallen off the frame, and then an '87' Nissan Stanza, which was dying at 130k when I bought the '99' Sonata.
 
I loved this car when I bought it, but I don't delay maintenance, baby the car most of the time, and I have a piece of Cr** at 56k!
 
Sorry to let the air out of some people's sails, but that's the way it is!

Hahaha. No, not really heavy labor, but it is annoying.
Here's what I recently discovered: We have two different seat/mirror settings programed as #1 and #2. We leave the auto button on with green light glowing. We nearly always apply the parking brake, sometimes after turning the key off, other times before. The seat either moves back a little or stays in my far back position #1 when I exit the car. When I want to re-enter, unlocking the car with the remote, sometimes the seat moves to my short-legged wife's setting, #2, but other times goes to my #1 position. If it scoots forward to her position, I just re-lock the car with the remote and then unlock it again, at which time the seat goes to my #1 postion. It can happen either way regardless of who last drove the car or which remote is used to unlock the door.
I don't understand why it behaves this way, but I'm happy enough.
MPG on the freeway cruising at varying speeds between 70-85 using whole tanks of gas gives 23 to 27 MPG for me, fully loaded, A/C on. Normal around town mileage, which does not include much stop and go traffic, usually averages 17 to 20 MPG.
2005 XG350 L, purchased new, now with 29,000 miles.

Latest news on my 2005 XG. The car has hestitated three times in 8000 miles of use. But last month the Traction control / antilock brake computer failed. The car worked fine, but there were three lights illuminated on the dash: TSC, Brakes and one more (?) Hyundai replaced the computer under warranty. The dealer contacted Hyundai about the hesitation, and Hyundai said if the new computer did not fix the acceleration problem, that the dealer should replace the accelerator position sensor. Our dealer in Iowa City seems very willing to do what it takes to resolve the problem. We have put another 1000 miles on the car with no hesitation.... and we are keeping our fingers crossed that the TSC computer was somehow the culprit all along. On a problem that occurs once per 2 or 3 months, it is hard to know if the problem has finally been fixed.
I wish other XG owners success in this adventure. Other than the hesitation, we love the car, 20/21 MPG around town, 26/27 on the road with A/C.

Capttv01,
  
I checked this out on my XG300 and the airflow out the rear duct is a lot lower than air flow out the front. This is not to say there is nothing wrong with your vehicle, but one thing to try is to close all of the front vents and see what that does for rear airflow. I tried it and got a bunch 'o air out the rear. Not the normal way you would use it, but at least you would know it is working. Also be sure the vent is open at the rear duct.
 
  I had my center console torn apart last week-end try to find some things I'd dropped down thru the gap in the cup holder door. (Yes I'm very dumb) Anywho, I was able to get a good look at the duct work that directs air to the rear vent. It is only about an inch in diameter from the front of the console to within a foot of the rear vent where it expands to about the size of the vent opening. You're not going to get gobs of air thru that small duct, but I've found that it is sufficient to cool the back seat area fairly quickly.
 
Hope this is helpful,
 
Rog Dog

I received a survey Hyundai regarding my trip to the dealer that offered nothing but a lame "dirty fuel injector" excuse with a $70.00 cleaning fix. I didn't sugar coat it. I also wrote in detail why I was unsatisfied. Since then I went to another Hyundai dealer to have the car looked at. I explained the same issue I was having every couple other day or so with acceleration problems on start up not allowing me to go more than 20 mph until I restarted the car 2 or 3 more times. This dealer came back and told me that I needed a new relay. They would have to order it and it wouldn't be until 2 days later that they'd have it so would I be able to come in then to have it put in. When I told them I wouldn't be able to and it looked like it would be after the weekend before my schedule would allow it, they said they'd see what they could do to get it in quicker. They called me the next morning and said they had the part and asked if I could come in that afternoon. Needless to say, that went along way with me at this point. The relay has been replaced and it's been one week without incident. I'm hoping this was the answer I was looking for. I will keep this site informed as to whether the first dealer contacts me because of my poor survey response.

#1964 of 2117 Fuel Door Problem by rastaspoon

Jul 26, 2006 (12:50 pm)

The fuerl door on my XG300 has this annoying issue with popping open. The switch flips open every few seconds, and doesn't stop, sometimes pounding on the inside of the driver side door works, but that doesn't seem to work either. I think it may have something to do with humidity or moisture....anyone?
Is this easily repaired by myself? I can't afford a visit to Mr. Hyundai right now.

Do you have the exact name/type of the "relay" that was replaced? The XG probably has a hundred relays. So far, not a problem in my XG since the traction control unit was replaced. But then it has only been a month. I will not be able to declare clear victory for another 3 months. I think the dealer has a lot of influence on how we view our XG's. If the dealer is willing to work through the problems, perhaps trying one or two changes based upon educated guesses, I think we will all be happy. Other dealers who wait for a specific computer code to appear, are very frustrating. One down side of driving the exclusive XG is that dealers do not get a lot of experience working on these vehicles as compared to the more popular Sonatas. My wife and I purposely did not want a first year Azera, thinking that the 2005 XG would be more mature..... Time will tell.

Well, It has been a couple of months since the traction control computer / unit was replaced in my 2005 XG... So far it has run like a charm. . . . Not a single hesitation event. I do not know if the problem was the computer, or some wire connecting to the computer. I know that some intermittent problems can be caused by poor contacts on electrical connections. I will not consider the problem as "fixed" until we go a couple more months. . . .

You know what, I don't know for sure. I will be visiting the dealer again soon for a pre 60,000 mile once over and I will ask then!
