2022 Tahoe Gurgling Noise Up Front (Engine?) Somewhere

[tahoe81]

My 2022 seems to make a gurgling noise fairly consistently. To me it sounds like it's coming from the front-right engine area but hard to tell. Just sounds like an empty stomach making a noise or something to me. Anyone else's do this? I really only hear it if I've got the radio turned down.

I'm not sure if this is the same, but I've heard that inside the passenger compartment coming from the front right area but figured it just coolant flowing through the heater core.

Normally the gurgling noise doesn't last more than a 5-10 seconds then it disappears.

If its the heater core, you are low on coolant or have air in the system.

If you have a sunroof, water can get trapped in the a-pillar area. There is a tsb to retrofit the water drains with hoses lower in the front fender to get them out of the high-pressure area.

Sorry, no idea how I missed this months ago, but my vehicle has done this since the day. I drove it off the lot brand new. I guess I’m wondering if I should still take it to the dealer to have them listen it doesn’t appear to be causing any issues that I could tell since I’ve driven it for nearly 30,000 miles at this point.

I did just drive a brand new Tahoe as a loaner vehicle when mine was being worked on, and I noticed that it did not make any gurgling noises

I have a 2021 Premier Tahoe. I too started noticing a gurgling noise coming from the center engine area when I hit around 35K/40K miles. It got progressively worse in frequency and loudness. Took it to the dealer and they said transmission fluid was low by 1 qt. They didn't find any leaks and didn't seem concerned by it..hmmm. Anyway it worked as the gurgling went away, for a while. About 10K later it's back again. I have yet to return it to dealer.

Next time you hear this try turning on the heater to full hot temperature. Maybe purge the core and stop the noise. Shouldn't take a minute to see if it works.

I’ve noticed hearing a gurgling in my 21 occasionally when driving it but I think for me it’s happening when the thermostat opens and it starts circulating coolant through the heater coil. The sound line makes is consistent with coming from the general area off center of the center console or near the passenger dash area (not sure where the heater core is located on this model but old models had it in that location).

Do you have a sunroof?

Thanks for the info. Had no idea about this and very helpful. Although I don't believe my issue is from the sunroof (my vehicle has one) as I hear the noise even when it hasn't rained in a while. Plus the fact that the dealer found the trans fluid to be low and then after filling it the noise went away, for a while anyway. Sounds like trans related but then there's got to be a leak somewhere.
