bdm62987 Posted November 28, 2016 Posted November 28, 2016 2016 Silverado, when driving the truck and pressing the gas pedal I hear a faint high pitch noise that comes near the drivers side door either underneath or in the dash, hard to pinpoint. The sound goes away when I release the pedal as well. Anyone else experience it? Its annoying as sometimes the radio cant drown it out
kdhs10 Posted November 28, 2016 Posted November 28, 2016 Mine does the same thing, sounds like alternator whine to me.
2016 Sierra Owner Posted November 29, 2016 Posted November 29, 2016 Do you guys have 4x4 trucks? It sounds like the selector swith module is what you are hearing.
bdm62987 Posted November 29, 2016 Author Posted November 29, 2016 Yes mind is 4x4, I will have to listen and see if that's it
2016 Sierra Owner Posted November 29, 2016 Posted November 29, 2016 Yes mind is 4x4, I will have to listen and see if that's it More info and module location http://www.gm-trucks.com/forums/topic/188605-high-pitch-electric-noise-while-switching-to-auto-and-4-wheel/
BigBadSierra Posted November 29, 2016 Posted November 29, 2016 Switch if from auto to 2WD and see if the noise goes away. My 2014 developed the noise about after a year. It can be a bit annoying. Regardless they know about it and will not fix it.
DaveHC Posted December 6, 2016 Posted December 6, 2016 my 2017 has the same high pitch whine from 25-45 mph then its gone even with radio turned off, annoying
bdm62987 Posted December 9, 2016 Author Posted December 9, 2016 It almost sounds like the truck is pinging or speedometer gear in a old car
LF2436Trucker Posted May 2, 2017 Posted May 2, 2017 Yes, I have the same problem on my new 2017 Siverado 1500. High pitched whine comes on at around 60 mph and gets worse the faster I go. At 75 mph its so loud it drowns out the radio. I have been to the Dealer about it. and getting the run around from the mechanics. And guess what the Service Advisor told me. He said, "Well, thats over the speed limit so you probably shouldn't be driving that fast anyway"! Wow....really? So, the new 2017 Chevy Silverado with a 5.3L V8 engine shouldn't be driven over 60 mph! Ok...got that in quote! Wow, what a disappointment. On another note, there is a posting in another forum, (2016 whining noise) from a guy that says the issue is in the transfer case. He got his replaced and it fixed the problem. I am pursuing that now, but its going to be a battle. If I can't get relief, I will just trade this thing off for another brand.
Rich Kesteloot Posted November 29, 2018 Posted November 29, 2018 I have a 2WD 2018 GMC Yukon and have the same annoying noise between 60-80 MPH. When I let off the gas pedal it goes away. only 6,000 miles on it.
Moore84 Posted November 29, 2018 Posted November 29, 2018 Anyone found a solution for this??? I have a 2016 and it only does it when in 4WD but it drives me absolutely insane! I may have dealer check as I can absolutely replicate it so it cant be denied, and the old "that's normal" aint going to cut it!
Rich Kesteloot Posted January 27, 2019 Posted January 27, 2019 (edited) Ok My dealer has been trying to help me with this which I do appreciate. They did take it in and replaced the differential(ring and Pinion) and they said they verified that it had excessive run-out. I was driving a 2019 Yukon as a loaner until mine was fixed and I noticed the same noise between 60-80 mph although it was not as pronounced. I received my 2018 Yukon back from the dealer and the same noise is still there and as loud as it ever was. The replacement of the differential(ring and pinion) did not fix the problem. I did tell them the loaner has the same issue so I wonder if they have to disclose this prior to selling that vehicle? I am now working with the owner of the dealership on trading my 3-month-old Yukon for another viable option. I just can't get over the annoying whining noise for a 50K plus vehicle. Cadillac/GMC/Chevy Truck and SUV bulletin regarding the same issue they had recalled for 2014-2016 products with a "high speed whining noise" It was a multiple step guide to fix this is which started with the Ring and Pinion then the drive shaft then the rear axle. See the link below on the bulletin. https://gm.oemdtc.com/7200/pip5196-rear-axle-gear-or-bearing-whine-noise-at-highway-speeds-2015-cadillac-chevrolet-gmc Video of whining/ringing noise, listen for it behind the road noise. At 13 seconds in the accelerator hits 77 mph to cruise. Edited January 28, 2019 by Rich Kesteloot
Brenthaylett Posted February 3, 2020 Posted February 3, 2020 Anyone ever figure this out. Mine is like the guy from the original post. Mine is while sitting and can hear it at low speeds. Goes up and down with the RPMs. Always in 2wd though. Mine is a 2015 gmc sierra lt
2015Hd2500 Posted August 11, 2023 Posted August 11, 2023 Mine has almost 200k miles and wines. Has to be the pinion bearing. Base this on the experience and the pinion is the only thing spinning fast enough to wine and this is under a load. Axle bearing rpm is a lot slower and hardly ever fails. It is easy enough to check the pinion bearing for play. Block the wheels, put in neutral and with you hand grab the pinion flange and check for any slop up and down and in and out. Should be zero play. Then pull the plug and check the magnet. Should be clean. Even if you don't find anything will be the bearing. Find a good mechanic with references with warranty backed. You can verify the location or source using a magnetic pickup and stick it to the transfer case and measure the Hz and amplitude at speed on hwy. Then do the same on the rear end. The one with highest amplitude is your source. I use a guitar pick up and a 12vdc amplifier. Works the best.
