2015 Midnight edition... At 33K experienced squealing coming from the front of the engine, from something turning the belt. They say it was the water pump and replaced it. 35K the same noise came back and this time they replaced the vacuum pump along with the compression belt and another belt. 35,750 miles and the noise is back AGAIN and LOUDER. The truck is currently in the shop, and we'll see what they say this time. Seems to me the culprit is larger than the aforementioned pumps! Annoyed.

Thanks for the post! I have or should say had the squeal........My belief was water pump seals? It's currently not making the noise? Life can't be this easy for me........It will come back no doubt....

Just found this old post..... I will resurrect it here in 2022. My 2020 suburban premier rst started this same squeal/whine noise about a week ago. Checked it out and it was coming from the water pump. It just hit 60k miles and I have the extended bumper 2 bumper through gm. My family and I were driving into town today and all the sudden I get a bad squealing/grinding noise. I opened the window ( to make sure it was me.... we live in GA). It was and all I could smell was coolant. Drove it straight to the dealer and made them give me a loaner because the rental car place was closed at 4pm on a Saturday. We left in a Tahoe trade in and I'll be talking to the service manager Monday I guess.

    • Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken. 
    • Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
    • I have 2 choices. 
    • Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop. 
    • Consider me amused. We are who we are, right?
