I purchased a 2015 Silverado with the 5.3 this weekend with 11,000 miles on it. Since i have been driving it and getting used to it I have noticed a faint whine from the motor at low speed accelerations (mostly from a stop). The sound increases as rpms increase up to about 2500 rpm. Other than that the truck performs flawlessly. Is this normal for this generation of 5.3s? Thanks in advance for any responses. This is my first Chevy and I am looking forward to being a part of this forum!

Mind kinda does this intermittently as well. I've always assumed the water pump is about to go ;)

Same here, sounds like a ford power steering whine issue but not as loud. My dealer continues to tell me it's the fuel pump, not sure i am buying that excuse though.

The mechanic at my dealership said that he had heard it in some other Silverado's. If it is normal,shouldn't it be heard in all of them instead of some?

My whine comes from the passenger seat. Stops when I accelerate slower or she gets out of the truck.

:lol: too funny. Update on what is going on: I ran the truck by the dealer and got a service manager to listen to it. He said its normal but i don't buy it. It seems to do get worse as the truck warms up. It is really noticeable when you rev the truck in neutral. Any ideas on what it could be?

I was talking to my dad about this just the other day. My 14 does the exact same thing you're describing, but his 15 has never made a peep. Its most noticeable if I've got the window down easing through a parking lot but yeah, there's a high-pitched whine when accelerating from a stop, and it gets louder as the RPMs climb. I'd love to hear some suggestions/solutions..keep us updated.

 

All I know is it's still under warranty :thumbs:

Did anyone ever get any feedback on this im about to scheduel an appointment with my dealer too look at it. It almost sounds like an alternator thats whining or a PS pump but these trucks dont have a PS pump as far as i know.

      Software Update

      By kickass audio · Posted

      when it's greyed out that is it's way of telling you that it's downloading the patch in the background. Eventually it will be fully downloaded and then it will prompt you at ignition shut down to run the update. I highly recommend doing the update once you get home and can run it a few times. I've had several issues with updates not going the first time around and I had to retry the update multiple times in my driveway before it was successful.   Some updates are huge and take awhile to download. You can help it by connecting to your home WiFi and keep the truck on service mode for the ignition and keep it alive for awhile on a battery charger too. There are specs it needs to be in for updating such as a full enough battery charge, no running ignition, etc.

      Software Update

      By Chuck FB · Posted

      I am not techy at all but wondered if you have the truck running but sitting still in park as some functions gray out as soon as the truck is moving. I believe in the settings for updates you can choose for it NOT to update and I wonder by chance if maybe that was chosen before and now it won't allow you to chose to press update, I think that is back in the settings menu where it has all the items one wants on or off etc. Also I assume you have a wifi connection and checked that it has some signal strength, not that it would have anything to do with the grayed out updates choice in that case. What I am thinking out loud of here may be be of no value but thought I would suggest it, sometimes it can be the simplest thing that resolves an issue.

      Dave's Auto (custom engine builder) tear down of L8T

      By Chuck FB · Posted

      The so called rare failure that some certainly liked to tout ( die hard Ford fan boys ) as per the lifter failing and wiping out the cam. Back when it started happening the blame was being pointed to the lifters and honestly I never did hear anything myself conclusively one way or the other on that. Ford themselves in I believe 2024 had a technical bulletin I will call it that came out and for some engine platforms they were reprograming the engines idle speed but also they had a software update for the oil pump which then some time later was said what that software update did as to be increasing the oil pressure at idle. It is a good question if that issue was completely solved as one Ford specialist mechanic youtuber said he saw failures after that time period. Like anything there would be the variables, what oil is being used and the OCI and how much idle time gets put on an engine. I've seen some comments to claim that the L8T isn't so happy with high idle time either but I also know that companies that require their vehicle to idle a lot on the job don't tend to get the oil changed often enough for all those hours of idle time and go off of the odometer.

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By bwiese · Posted

      My 2026 Silv. 1500 WT (reg cab/short bed/4wd) has the 40/20/40 with storage in lower middle seat as well as the fold-down center bolster/armrest.   With the dual glove boxes this is about as much storage as possible in a std cab IMHO. Bill

      2026 Silv. 1500 WT reg cab: how many speakers do I have? Is amp module separate?

      By bwiese · Posted

      I have a 2026 base 1500 "WT" regular cab with basic Chevy "Infotainment 3" 7-inch screen/radio. How many speakers do I have If I want to upgrade? Is the audio amp separate from the radio/display unit]? [I listen to classical and it gets a bit raspy at slightly higher volumes. Don't need a sub etc.] Do I have two or 1 speakers in the doors? etc. Thanks Bill  San Jose
