Cold start screeching noise

[G-676450]

Had a chance today to record the noise, it's 23F outside, the noise seems to come from the engine (IMG_4895.mp4), have you guys heard this from your Telluride?
Another service is scheduled on next Wed, but it won't be cold enough then, I will show them the video.

YEP! That's DEFINITELY the sound! I have the same thing on my 2021 SXP. The dealership replaced a crank pulley put it clearly wasn't the answer. I hope we find an answer soon!!

I’m having the same issue. Dealer said they couldn’t reproduce it (of course not, it’s only on cold starts and I had to drive it to get there) and have no idea.

Frustrating and concerned it will become a bigger problem later

I'm having the same problem on cold starts. Dealer thinks it is the high pressure fuel pump. Has anyone heard of this theory? Does it make any sense?

 

[dtburgh]

yup, mine did the same when it got extremely cold last month. now it will make a noise when its warmer now, but not as long or as bad, so i wonder if it did indeed damage something? i like my kia, but i think they are cheaply made sadly..

Listened to the sound clip. It's the squealing exhibited by a stiff belt due to cold temps. After a few seconds, the belt begins to warm up from friction and as the belt loses it's "frozen" bumps caused where it sits around pulleys and such when the engine is shut down.... the belt becomes more pliable and because it's then flat and pliable, making full contact consistently, there's no slippage and thus no squealing. Assuming the belt is showing no actual signs of wear, and everything is in proper alignment, then it comes down to a matter of how to stop the belt from squealing. Sadly, no amount of parts replacements is going to address this, aside from a potential consumable item.... the belt itself. I've experienced this on other vehicles and it has nothing to do with build quality. Replacing the belt with one of identical spec from the OEM manufacturer will result in the same problem All I can suggest is to change the belt to one that's of spec but made by a different manufacturer might work better, but that's speculation on my part. Something you can discuss with your dealer's service manager. It could be another item failing, but I'm highly suspect of that. I think when dealerships begin replacing pumps and pulleys, it's an act of desperation... literally grasping at straws. The service manual for the vehicle doesn't mention pumps as a source of squealing. It does mention the possibility of a pulley bearing failure or lack of pulley/belt alignment. Alignment issues would show some physical degradation of the belt itself. A failing pulley bearing would not, unless the pulley was completely seized... in which case it would cause belt damage. In the latter scenario you'd be able to smell it.

Im fairly positive it is not a belt. Sounds more like a bearing , something metal etc. I’ve heard belts squeal before and I think that’s nothing like the sound mine makes. It’s almost ear piercing it’s such a high pitch.

im 99% sure thats not belt noise. ive heard that over the years, and my noise is almost ear shattering. it has to be metal on metal or something similar in my opinion..

Belt squealing can easily sound like metal on metal. It can be loud. Insanely loud. That's what I hear when I listen to the sound clip. But if you want to test your theory, it's easy enough to do. Use a temperature probe (the kind like you use to check body temps, and has two settings.... one for bodies and one for "other" heat sources... like ovens, etc.). Just aim it around different parts of your engine while it's running. Aside from the exhaust manifold, if you've got a metal on metal situation going on, that will show up as significantly hotter than everything else around it. We use them to test thermal blanket effectiveness when applied over turbos. Additionally, if it's a metal on metal situation, that's not going to quiet down or stop as the engine heats up... unless the components actually completely seize up against each other, and in that scenario you're going to spawn at least one CEL condition and the ECU might even prevent any subsequent engine starts to reduce further damage.

like i said above, just my opinion. ive never heard belt noise like this in over 45 years.. and now mine will make some noise when its warmer out when it never did that before, hence my damage theory... i appreciate the reply, but dont appreciate the laughing emoji. no reason to be a dick about someones opinions or thoughts..

Would an idler pully replacement help with belts? I had the idler pulley replaced in my Sorento and it didn't help. Earlier in this thread I did post a video with the sound and hood up. Here is a link to my post and videos: Cold start screeching noise

I only barely heard the noise this winter, BTW. It was just too mild...it was only a faint noise for a moment.

 

[RickM]

YEP! That's DEFINITELY the sound! I have the same thing on my 2021 SXP. The dealership replaced a crank pulley put it clearly wasn't the answer. I hope we find an answer soon!!

UPDATE: Not only did they replace the crank Pulley, they replaced the belt, the A/C compressor, and most recently, the alternator due to excessive corrosion...still didn't fix the issue!! I've had the noise happen as high as 38 degrees F when I made it the last stra before taking it in. I have that on video as well. I have several videos of this crap happening. They've had my 2021 SXP for over a month. I have 2023 Forte GT-Line as a loaner until i get it back. I sure do miss my Telly!! Today is 19MAR24

I have this issue on a Hyundai pallisade anyone find the culprit. ?

I haven’t but my dad thought it might be the cold constricting the belt. So it would put too much tension on things to create that noise. Im not looking forward to this winter. Mine squealed a little when it was around 30 the other morning. :/

Sorry I bruised your delicate ego. Is calling someone a dick for trying to take the edge of a challenging issue better behavior? Or is that sort of thing only acceptable when you're the one doing it? Chill before you work yourself into a frenzy and give yourself a heart attack.

Relax keyboard warrior. I just didn’t think the laughing emoji was appropriate, like your opinion and thoughts are the only ones that matter.

Hello, ive had this problem for many years also, but when you put it in reverse it stops?
My Kia dealership was never able to fix this issue...just told me that they would keep an eye out for a recall..(telluride nightsky 2021 edition)

wonder if you put it in N if noise would go away , if that’s the case I’d leave in N overnight with park brake on

 

[BraydonF31]

Wondering if we could put a little heat to the throttle body with a hair dryer and see if it will make the sound go away … could eliminate our moisture build up theory and if techs saw that they may now have proof it’s the throttle body

If you remove the belt still makes the sound, therefore it eliminates pulleys and bearings and belt

Mine is making the noise again now. The first winter there was no noise for me, but only the 2nd winter.

I did have the throttle body service done just prior to the 2nd winter when i started having this issue. I have had this on the back of my mind, but I don't know enough about cars to make an informed suggestion to the dealer. They did replace the idler pulley and tensioner but that did nothing. My dealer replaced the alternator in another Sorento with this issue and that didnt fix it for that car.

I'm getting to the end of my factory warranty soon...I'd like to get to the bottom of this. I have an extended warranty but I'd rather not have to use it for an existing issue like this.
