Replying to: sa258 (Jun 14, 2009 5:53 pm) ynk4r AND sa258 -- I wish I had an answer for you both. But it sounds like your problem is much different than anything I encountered. I was having acceleration problems at high speeds after 100 miles on the Interstate. My Tucson has never stalled out on me.   pcherry328 -- I ended up having 3 different places try to diagnose my problem (2 were Hyundai dealerships and 1 was a little shop in the middle of nowhere). All 3 had different ideas. The little shop suggested that I had some water in my fuel. Not sure if that's the case.   Either way, I've only had the problem when my tank was below 1/2 a tank. So now, when I go for long trips, I stop every 100 miles and fill up the tank. So far, so good.   Sure, that's not an ideal solution, but it beats the alternative.   Have you been having better luck, yourself?
#10 of 18 06 Hyundai Tucson 4x4 -- SAME PROBLEM--Chrabnk Shaft Sensor? by kytcoug Jun 17, 2009 (6:13 am)
I am having the same problem described by everyone above -- engine was fine until 60K (when the warranty ran out) Tucson engine gives out on interstate, sometimes on my local country road at 50 mph. The engine looses power for a while, check engine light comes on, then problem corrects itself and check engine light goes off. Shops never see anything because the engine sensor reset and don't store in memory why the check engine light comes on.   My mechanic suggested it might be the crank shaft sensor (tells the fuel pump how much fuel to give engine). He showed me 9 webpages of complaints from owners describing the same problem and the crank shaft sensor was the source. Since then, I have had one delay and the check engine light came on--so not convinced that was the issue. I have wondered if using the cruise control might cause some of these problems, maybe it gets"stuck" Perhaps fuel filter and pump, but that's a huge cost.   Anyone have any suggestions on this one?

Replying to: ynk4r (Jun 11, 2009 1:58 pm) I just am wondering if all of you have 6 cylinder automatics. I bought a new 2006 Tucson with the 4 cylinder 2.0 liter 140 horsepower engine. It has the locking 4WD which was the last year they offered it with the standard transmission. So far at 48,000 no problems whatsoever except for a leak in the power steering unit which they replaced without a problem. I find the 2 liter plenty powerful with the standard tranny although very steep hills are a problem. I routinely use it to haul.   I'm just wondering if this is just a problem with the 6 cylinder models and the auto. If so; the problem may be transmission related. I have never liked automatics and will always go for the standard if offered. I would suggest that you may want to go to non dealer mechanic that you trust. I never go to the dealer for maintenance. My mechanic of 20 years seems to have kept my Tucson going with no problems and no unwarranted maintenance. Your dealers may be hiding something and from the maintenance section of this forum; they are quite a few dishonest dealers out there who depend on your maintenance and repair dollars for their survival in this economy!

Replying to: butch30 (Jul 14, 2009 6:18 am) I do have the 6 cyl. auto...had the fuel pump and filter replaced and no more stalling problems..i can feel it getting more power. Lets hope that did the trick. Replies to this message: sa258 (Jul 26, 2009 5:44 pm) kytcoug (Jul 27, 2009 6:23 am) dalev2 (Jul 27, 2009 6:56 pm)

Replying to: kytcoug (Jul 14, 2009 6:32 am) Why did you have the fuel pump and filter replaced?? Did any lights came on to let you know where the problem was?? Replies to this message: kytcoug (Jul 27, 2009 6:23 am) dalev2 (Jul 27, 2009 6:56 pm)

Replying to: sa258 (Jul 26, 2009 5:44 pm) The check engine light did come on and the code was a misfired 5th cylinder. My impression was that the engine was not getting the gas it needed as it would cough and stutter when I tried to climb hills or increase power, the pump and filter seemed to be the cause.   While the new the pump and filter did improve road performance, now I have a long crank before it starts up. Upon further inspection, we noticed an air filter control valve for the gas system that was completely clogged with dirt; the mechanic banged about two cups on the telltale red dirt from the road I live on. With this clogged the engine does not get the correct gas/air ratio, the engine floods and will not start until it can get enough air the third of fourth try. It also starts easier when colder outside (air is more condensed) then when it is hot (air expanded). This could also cause the engine to struggle when more power is needed...basically the engine can not breath.   I bought a the 4x4 Tucson small because I live in the mountains on on a dirt road. I also drive many back roads looking for hiking and camping spots. What seems really stupid to me is that a 4x4 SUV has a system that gets clogged with dirt after only 1.5 years of ownership.

Replying to: kytcoug (Jul 27, 2009 6:23 am) for what its worth, my Tucson has never been off road, I don't live on a dirt road, and the air filters have been changed (by me) at twice the rate that is suggested and yet I encountered the problem going 60 mph.............so I don't believe it is due to a clogged air filter, etc. As for changing the fuel filter and pump, Hyundai in their inscrutable way saw fit to put both of these items in the fuel tank. Good Luck trying to replace these at home, since it requires draining and dropping the fuel tank. The stalling is an obvious problem that seems to be occurring to a number of people and its only a matter of time before someone is involved in a serious accident. I guess both Hyundai and the government will look into the problem then. Until that time, cross your figures and hope nothing happens. Since the problem occurred in my wife's Tucson more than a year ago, it has not reappeared. C'est la vie.

Replying to: sa258 (Jun 01, 2009 6:29 pm) Brand new 2009 Tucson, driving it home from the dealership and it did exactly as described, stalled at a stop sign. Car is still at the dealership 24 hours now with them completely unable to figure out what is wrong. The diagnostic computer is getting nothing from the control unit, even after they swapped out units from other Tucsons on the lot.

Replying to: ynk4r (Jun 11, 2009 1:58 pm) Bringing our 2009 Tucson home from the purchase, it did exactly as you described. I had drove a deliberate 55 mph home from dealer, a distance of under 10 miles. First stop sign after exit from the hwy, it did the sputter/stall/not start thing. Had to shut it down and restart before it recovered. Took it back to dealer and they are (still at the time of this writing) unable to get any information out of the control unit (diagnostic computer is completely blank when hooked up to unit). They swapped out control units but problem remains of no info coming out.

Replying to: butch30 (Jul 14, 2009 6:18 am) 4 banger with auto. A/C was running at the time. Like I said, was coming home from dealership 1st time so don't think dirt etc. a problem (3 miles on vehicle, 13 when got home).
