I have the same issue. Light rattle when I hit the gas. That's even when the car is all warmed up. I have a appt with them Friday so I'll tell them to take a look.

 

Good to know...

 

good catch guys. from what i have read about other excessive turbo wastegate noise, it could be as simple as retensioning a retaining spring or maybe just replace it with a stronger one. i guess we will just wait and see what the fix is.

 

It's been about three months since the original post.

 

mine flutters for a few seconds when I start the car.. I give it a quick rev and it's gone. At this point, it doesn't hurt the car and it doesn't affect performance so I am not worried at this point. Apparently it is a common thing amongst turbocharged engines.. If a fix comes out, then I will handle it, but at this point it's not really a concern.

 

I am not worried at this point.

the same

 

And mine still makes the noise. It's at the dealer now for steering again. I will have to ask when I go in next if there is any update. They seemed to think there was a TSB/Recall last time I was in but if they performed it, it didn't make any differrance.

 

just saw this, on a Optima Turbo, and I guess it explained what's happening and there is a TSB on Sonata Turbo which simply said "No repair should be attempted for this rattling or buzzing condition. This normal operating characteristic will not affect the performance or durability of the vehicle."

2011 Kia Optima SX Turbo: Cold Start Jingle

 

I had my car in on Friday and they applied this fix. It's much quieter on start-up now. I hope it helps with otherissues I'm having, but we'll see.

 

I'm missing something...what fix? Was this from a TSB?

 

i thought thats just how it was on start up, because after like a minute of driving i didnt hear anything anymore.

also noticed that some days on start up i get a high rev for about 5-10 seconds in the 2200rpm range....is that just to get the turbo warmed up?

 

I believe the high idle and waste gate being open (rattle) is to warm up the catalytic converter as quickly as possible to reduce emissions as soon as possible after startup.

 

yes a TSB [ENG104] for the wastegate rattle issue just got posted. They had to reprogram the ECU.

 

Thx, I checked KGIS and found the TSB. I'll take it in to get it done soon. Just this week it finally got cold enough in AZ in the morning to hear the rattle.

 

thanks for the heads up. i was planning to take my sportage to the dealer to get the first oil change this weekend. i printed out the TSB and will ask them about it. no other issues at all.

 

can anybody else confirm that the TSB actually eliminates that rattling noise on startup? I would love to bring this to the attention of my dealer..

 

Good luck. I had a discussion with my dealer this after noon on this technical bulletin. He might look, but he found nothing in his system in Canada ...
Just send him a copy by email. At the moment the technical bulletin seems to be valid for the United States and in Canada, unfortunately, the problem seems to be the fruit of our imagination ... to follow ....

 

well that's encouraging.. Kia Corporate knows about it, and we know about it, but the dealer's know nothing..

Gotta love it..

 

hehe.. The KIA service department doesnt know of a TSB about the wastegate either.. All he said that he will have one of his technician look into it before my appointment on Monday... I told him Ill bring him a copy in case they cant find it.

 

interesting...im at a dealership in canada and the only problem that kgsis lists is a service action for inspection of the wastegate rod, there is no mention of a noise but to check for a DTC trouble code, we shall see when it starts to get cold here in canada. i started up a turbo optima this morning and i did not hear any noise and it was 0*c this morning

 

I just have the pleasure and great honor to receive a phone call from my dealer favorite, followed by a technical bulletin for the wastegate in Canada. The good news is that they are able to open a pdf document

As mentioned above, the technical bulletin applies for the moment that the U.S. side, it may take up to two months so that it crosses the border to the Canadian side. The bulletin is dated September 2011, he predicts that in November 2011 it will be with us .... for now it has the update 168, need to go up to 170 for the waste gate mod ..

stay tuned

mod: Two thread for the same subject is it possible to merge them?

 

if someone could please upload or pm me the PDF from kia that would be awesome i work at the dealer in canada and i can foward it to tim oconner at kia canada. im sure it will be good to have around as the weather will get to -45*c here lol

 

as requested

here is the pdf

 

you must be out west rx7..

 

haha well Saskatchewan but yes classified as west . i would really like a copy of the TSB

 

awesome thank you very much

 

so i brought my 2012 sx into the dealership for it's first service this morning (3000 miles, yes it's a month old ). they are done after about 30 mins, but did not flash my ECM. i even brought the TSB printed out and talked to the service manager about it. He scanned my vin and the GDS system reported that it did not have any needed updates. So either this is not an 2012 sportage SX issue, or they haven't pressed it to all vehicles. it's kind of weird because on kgis, if you look up TSB's for the 2011-2012 (SL) sportage, then select the 2012 year, it still shows up as a TSB. i for one am glad that he doesn't just shoe horn it in, because the computer system is designed around the vin. so when he scans the vin all updates come on the screen. Also, the service manager has flashed this TSB update to a lot of 2011 sportage sx's. so i guess i have nothing to report other than that it (apparently) didn't apply to me.

as a side note, they had a bunch of 2012 optima sx's in stock. very nice looking car. might take it out for a test drive when i go get my sportage later today.

 

I took my 2012 SX in for the 6,000 mile service yesterday and the service dept told me it didn't apply to me as well. I don't have a rattle (they didn't ask) but I do have high revs at cold start.

 

Higher revs (than normal) at a a cold start is normal with any car.

 

This TSB better apply to me cause mine rattles at a cold start. Its gonna be hard to show them since By the time I get to the dealer the car is going to be all warmed up. Might as well take some video so I can show them it rattles even if the car is warmed up.
