Why did you have the fuel pump and filter replaced?? Did any lights came on to let you know where the problem was??

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.

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.

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.

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.

I am having similar problems with my 2005 tuscon 6cylinder automatic. The problem started after I changed the battery and the sparkplugs and wires. Incidently one of the mechanics that looked at it told me it did'nt have a gas filter. The dealers told us it needed a new computer chip. For about 3500 dollars. I have to believe it has something to do with the tuneup and new battery. Did anyone on this thread every get this issue resolved?
