Ok guys, here is the problem I'm having. I have a 2009 Santa Fe, SE, 2WD, 3.3L V6 with 30,000 miles on it. I change the oil every 3k miles even though the manual says 7.5k and have replaced the cabin air filter as the manual calls every 10k miles. I do all the maintenance that is required by my manual to the T.

The other we were driving home and it was very hot, about 100 F. We had the a/c cranked all the way and we got off the interstate the motor just died. I plopped the car in neutral and turned the key and it fired right up. I thought maybe it was just a one off fluke and would monitor it for a while to see if it does it again. Yesterday I was backing out of a driving after driving for about 30 miles or so and the engine died again, i plopped it in neutral and it started right up. Both times there were no check engine lights or nothing on the dash. I brought it to the dealer that I bought the car from and they said there were no codes when they did a scan so they went ahead and looked for other things that could be wrong. They noticed that the throttle body had alot of carbon build up in it and said that this could cause the flap in the throttle body from opening or the sensor in the throttle body could be going defective but they couldn't replace the sensor without a code under warranty. The guy also said that excess carbon build up was normal on Hyundai's and this was routine maintenance and they wouldn't fix it for free as I should have it cleaned every 15k miles. After arguing back and forth they decided to fix it for free. Here are a few questions I have and was hoping to get answered:

1). What would cause the motor to just shut off without any check engine lights or codes?
2). Could excess carbon build up cause the motor to just turn off?
3). Do all hyundai's with the 3.3 get carbon build up like this after 30k miles? Does everyone else clean their throttle body every 15k miles like the dealer said we should do?
4). Would any of you call this regular maintenance when it's not in the manual?

I wrote Hyundai Motors an email asking them if this correct but I figured I would ask the community as well. Any feedback would be greatly appreciated.

My '08 has never had a throttle body cleaning, and it runs fine with 65,000 km on the clock. There was a thread on this subject (http://www.hyundai-forums.com/index....4&hl=butterfly), but nobody in that thread reported a stalling condition. And as you correctly point out, Hyundai does not recommend cleaning or even inspecting this part in the owner's manual.

Methinks your dealer is exploiting this situation to promote its maintenance services, when it should be more concerned about solving your problem. Hopefully I'm wrong and the cleaning is all you needed, but if the vehicle stalls again I would try another dealer. Good luck.

Thanks for the reply don. Would you consider this routine maintenance or was I right to argue that this should be covered under the bumper to bumper warranty? The service manager gave me a bulletin that went out to all hyundia dealers in November 2010 that says they recommend to use a can of fuel injection system cleaner once every 3k miles on ALL hyundai's. I'm starting to wonder if this is actually a problem across the board on all of their vehicles. But i still have never heard anyone say they to clean the throttle body/fuel injection system every 15k miles.

Every 3,000 miles? Really??? Each time the dealer has tried to get me to do the throttle body/injector service I was told it was "recommended" but it's not a must do to maintain warranty according to my manual. The TSB is attached though. Notice it points to GDI engines.

And this is the only TSB I found concerning cleaning the throttle body

Pinto, the first bulletin you posted is the one the service manager gave me. According to him I should use a can of this stuff every 3k miles and get the throttle body cleaned at 15k miles by them.

If the owner's manual had said "inspect throttle body every 12 months", then I would agree that it falls under routine maintenance to clean it when dirty. But the manual makes no mention of this part whatsoever. The only reference is found in TSBs, which are written after the fact to assist technicians in resolving problems. That makes it a warranty issue IMO, not an owner obligation.

I'm sure that with enough digging around we could find a statement by Hyundai recommending against using these products. But that was before they had their own in-house brand to sell.

Bottom line is that it's not a required service item and therefore not a condition of your warranty.

thanks for your opinion Don, I feel the exact same way. To me the biggest disappointment is that Hyundai is treating their customers like this. If i didn't know a thing or two about cars I would have no clue what they meant by throttle body cleaning and would have believed them when they say it's routine maintenance and not covered under warranty. It's sad that these dealers can make 200 bucks off of people that don't know anything about cars. Like I told the service manager, if this is really the case that the throttle body needs to be cleaned professionally every 15k miles, Hyundia has built a pile of junk and they will be the next Chrysler/Government motors.
