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.

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,

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.

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!

I'm surprised to see the mpg is that good on a 3.3L engine. I'm debating between the XG350 and the Sonata GLS V6. The XG has more features that I like than the Sonata but the Sonata has better mileage. I have a 2002 Honda Accord now and I've never really been impressed with it. I've had it for just under a year. Is the XG really comfortable? I'm almost 70 and figure this will be the last car I buy. I buy all my cars from Car Max and intend to get the next one there also. They don't have a lot of these in stock and in fact here in Nevada they don't have any at this time. Is the leather soft or stiff like some? I hate leather in Nevada but thats all that comes in it I guess. At least buying it used it should have all the bugs out of it. Their cars are like brand new with very low miles but very good prices. I've done the new car scene to many times to do it again. I'm curious about the mileage on that motor. I was afraid the 3.3 would be hard on gas. What grade of gas does it use? Thanks

Our XG350L has a 3.5L engine, which is very spunky. In Iowa, we always use the mid-grade ethanol (89 octane) blend, since it is cheaper than the low-grade gas. Most of our driving is open road between towns at 60 - 70 MPH as we always get mid-twenties. On pure highway, we get 26-28 with AC running. Around town, the MPG depends on your gas pedal practice. If you drive it like a Corvette, the MPG would likely be low teens.
The leather is firm. I expected it to soften over time, but it has mostly stayed firm. My wife has a touchy back, and the comfort of the seats was a prime selection criteria for us. I do not know if leather was standard in the non "L" version of the XG350. The XG350L was the luxury version of the XG350.
Good Luck !
#1970 of 2117 Speedometer/cruise control failure on 2002 XG350
Sep 03, 2006 (4:56 am)
I have been having a problem with the speedometer of my 2002 XG350 (90K mi) that I haven't seen on this forum. It started about a month ago with a bouncing needle that would occasionally drop to 0. When this would happen, it would confuse the cruise control generally shutting it off. It occasionally confuses the transmission, causing the car to buck a little. Recently the problem has become more consistent. The needle drops to 0 for a few minutes at a time at which point the odometer stops working. Also the cruise control no longer will turn on. I was wondering if anyone has any insight or experience on this issue. I have little failth in the local dealers and would like to go in with as much information as I can. Thanks, Vic
