2016 GMC 2500HD Chime Uncontrollable

cmaddox03 · March 15, 2022

I'm having issues with the chime in my truck. When I turn the key on, the chime will sometimes be extra loud (over 100db on a iphone app). Sometimes it will be all 5 dings will be loud & other times it will be the first ding loud then the rest normal. I've verified that the chime volume on the settings page is turned all the way down. I took the truck to the dealer for another item so I had them check it out. They said it is normal for these trucks to have loud chimes (blowing me off). I've had the truck since new & now has 204k miles on it. The chime used to be normal.

Only major changes to the truck was deleting it July 2021.

Appreciate any ideas.

Following. Mine does the same thing.

I've experienced the same thing in an 18' Sierra 1500 Denali...has done it maybe 3 times over the past year with no direct cause. I thought I was always crazy for thinking it was abnormally loud until I saw your post.

I'm guessing it's just something wonky in the programming logic...for example I've had the radio switch favorites while turning the truck off and then the radio stayed on even though the key was out, driver door had opened & closed, and the truck was locked.

I'd check your grounds to make sure they're tight and clean. The one behind the passenger front splash shield is a popular one to check. I'm not sure if GM fixed the insulation problem by the 2016 MY, but there is one in the dash that can cause issues if the ground is touching the insulation. There are videos on YouTube on how to fix this.

My 17’s chime is a douche. The settings adjustment doesn’t do a freaking thing.

The dealership has an amplifier on order for the truck. They said that is what GM suggested. Fingers crossed that it fixes the chime.

I got the amp replaced last week at the dealership and it fixed the chime issue. I assume it was a short or something in the amp. It didn't take them long to replace the amp (it's behind the rear seats). I thought about doing it myself but the work order says there is programming involved.
