Cold start screeching noise

[blitt]

Have been following this discussion for a long time....decided to throw in my "two cents"...... I don't think this is a "pulley/belt" issue. I believe it is most likely some sort of "intake" or "gas compression" issue......over the years, I have had a Mercedes GL450, Caddy Escalade that had a similar issue as well as a Ford Explorer that also made the sound. Always on very cold days ( temps below 20) My 20 Telly makes the same very quick noise under the same conditions.....and having taken all of the above vehicles to a place in New England in the winter where I park them overnight in -10 + conditions and heard the sound to a louder extent AND that I have not noticed on the Telly nor noticed on the previous other vehicles any other related issues, I have decided to simply assume that the electronics and all other systems related to the combustion and climate control aspects incorporated in most of our modern vehicles simply do NOT like very, to extreme, cold weather.

If it is a leak on the intake, I would hook up a smoke machine and see where it is leaking from.

I'm not sure if there's a leak, I suspect that it would shoot a code if a leak is there. If you read the first pages of this thread you will find some discussion about the moisture built up in the throttle getting frozen in the night and making the whistling sound.

If there was moisture build up on the throttle body causing a leak the smoke would find it’s way out the throttle body.

Just back from the dealer about this issue and they say it's known and it's on all their V6s. Apparently related with some hydraulic fluid becoming too viscous. According to the guy Kia should come up with a recall abou tthis. As customers we just need to report this will increase the priority on the issue. Apparently not a problem just a bit annoying...

What hydraulic fluid would that be? I'd like to mention it to my dealer if possible. Only problem is that Kia Canada and Kia USA don't always co-ordinate this type of thing.

Just got our 2020 palisade back from the dealer with this same noise.
They replaced the idler pulley under warranty. No idea if it actually fixed the problem since it's been above 32° here. If it doesn't solve the noise, I'll report back.

Quick summary. The whirling noise started this winter on the first sub 10° morning, first start when cold. After that initial incident it would make that sound at warmer temps but still under 32° on a cold start.

Now we just have to get the windshield fixed that mysteriously cracked while sitting in the driveway.

Sorry I did not register the info in details. I think I should ask for a statement and report to Transport Canada. Probably the only real way to eventually trig a recall! They say it won't cause problems but I kind of doubt that...

Just spoke to the dealer and they don't know what to do next. They determined in another vehicle with the same engine that the same noise was coming from the alternator, but when they replaced the alternator the noise was still there.

So the dealer suggested I contact Kia Canada, which I have done. I have a case with them, and they will be in touch with my dealer. I spoke to a level 2 tech and she said there was no documentation of this noise.

Did you open a case with Kia Canada?

I also noticed this noise almost a year after when I left the car out for 2 days in cold.

It sounds very similar to my What snow thrower makes when I engage the author.

Author is belt driven and pushing the lever just pushed the pully against the belt to increase tension.

Just saying.

No I didn't I assumed this would be dealer responsibility... I'm going to ask on my next visit to the dealer and I consider filing to Transport Canada to eventually force a recall. From experience so far I feel like Toyota is a bit more after you with recalls where Kia seems to be trying to avoid them. I'd have to check stats if any to make sure but this is just a feeling from my own experience and a few others...

Thanks for the suggestions! I will record the sound before the service, actually 'We cannot duplicate the problem' is something that worries me more. Tried to find some videos about slipping belt, but it sounds intermittent or rhythmic, yet the noise from my car is high pitch and continuous, that makes me suspect about the belt. It seems to be a quite common thing on Kia models but I haven't seen it from Telluride, I live in Central New York where temperature varies a lot in a year and winter could be very cold, typically the colder the weather, the louder/longer the noise, but only happens in cold morning.

My telluride is in the dealership right now for the same exact problem. Exactly what they said we cannot duplicate the problem. instead of having them keep it another night, I think I will get it and record the sounds also. Good idea

Mine only did this noise once for about 2 minutes. Since then it has been parked outside but hasn’t.

This car can heal itself!!

2014 Hyundai Santa FE
Similar noise on cold starts.
Does not last as long when block heater is plugged in.
Starts 10 to 15 seconds after start. Can last up to 45 seconds to one minute depending on how cold it is and if plugged in or not.
If plugged in only makes sound for 5-10 seconds.

I have a Kia Sedona 2020 and whines like this too below -15c. Synthetic oil didn't change anything.
If I use the block heater, no more whines. One hour plugged isn't enough.
At -25c, it still does it, but very faint and for a few seconds.

I am a Kia technician and I have heard this on a couple tellurides and can say that Kia has no idea how to fix this. I have a vehicle in today with this issue, but it is 45F degrees here so I have not been able to duplicate it. I was able to duplicate the noise on the last visit when temps were in the sub-zero range. Kia techline had me remove the throttle and remove a couple plastic "flaps" that were inside the intake manifold. the manifold is made by sandwiching two pieces of plastic together and them melting/vulcanizing the two pieces together. This techline agent thought it may be the plastic that squishes out where the pieces meet. Removing the "flaps" made no difference. I am pushing to have them authorize me to replace the intake manifold. I will update this thread if we find anything.

OK so my Telluride has been in dealership the 2nd time, they just told me the noise is not long enough to diagnose, technician suspects it's from engine intake manifold or around it but cannot find the point, so in this way Kia won't reimburse any parts/labor. I also called the Kia customer support and it has no help, simply said if dealership cannot find the source of the problem, they have nothing to do. Both side are telling me to live with a problem that is related with engine, until it get worse or break down. Totally disappointed.

Did you ever get this figured out?

 

[keithfoco]

FYI: this seems to be happening on a percentage of all of the V-6's and not just Tellurides.

It's really good to see someone who works on this problem! Unfortunately, the dealership in my place didn't want to work on a problem that is not easy to duplicate, you can't debate about it when you are not able to find a 2nd Kia dealership in a 50 miles circle. I'm really interested to see if Kia allows you to replace the intake manifold and if that works, but I guess you won't have a chance to verify it as the weather is warmer now. Thanks for updating this with us!

I escalated the call through Kia and they were going to dispatch a field service tech, but since it's been too warm and not making the sound he decided not to come out. My problem is that every customer that has this issue won't leave it with us long enough to actually fix it. Everyone thinks it's easy. It isn't. It is going to take many days in sub zero weather to get this figured out. I have concluded that it is related to something in the intake manifold but need to nail it down to a specific part. The fact that every V-6 seems to do this and none of them pop a code or seems to be doing any damage to the vehicle, it isn't a problem that Kia engineers even know about.
Also, even replacing the intake manifold won't fix it if they haven't modified the intake based on the noise.
As far as I can tell it isn't causing any problem other than an annoying, embarrassing noise.
