2021 GMC Sierra 2500 Denali HD Tow Mirror - Issues

2021GMCLP5 · September 22, 2022

Im having issues with the fold function on my power tow mirrors. The drivers side folds in and out just fine. The passenger starts to fold and then stops. If i slightly push while folding it goes, and it goes manually. it also opens up just fine. It just wont fold in on its own.

Anyone have any ideas? I tried to reset the mirrors and it didn't work. looking to not spend 1k on a mirror as this one has the camera. Any help would be appreciated.

Aren’t you still in warranty?

I am not, it has 37k miles on it. But i tried resetting it one more time last night and it worked, folded them 5 or 6 times to make it work, hopefully its fixed for good.

I just bought a 2021 3500 HD and I am having the same problem, but only on the driver’s side. I wonder if it is a plastic gear that has some teeth worn off?

I was thinking the same, but it works for me sometimes, and in the rain it works... i also wonder if dirt and debri may be in there?

I had similar issue. Passenger side mirror got noticeably slower to retract/extend relative to driver side. Eventually it didn't retract on its own. I extended and retracted again and it would work. That happened two or three times before it finally refused to move at all.

I have to retract to get in my garage. The second time I manually extended, after manually retracting to get in garage, I had done the manual extension before I used the button to extend the driver mirror. When I extended the driver mirror the passenger mirror made a huge pop, really huge pop.

It has been working perfectly ever since. The speed matches the driver side and everything. It has been months since that has happened.

No idea what was happening or how it fixed itself, but it did.

I bought a 2021 GMC Sierra with power tow mirrors in December of 2020. These mirrors must be folded in daily to park in our garage and at other times to park in public spaces or to go through a car wash. The driver side mirror was replaced for not functioning in 2021 while under warranty. Now, the passenger side mirror is not folding out. The problem is intermittant (sometimes it folds in half-way), but right now it is not folding in at all. I had purchased extended warranty. My service advisor at Amery Chevrolet in Wisconsin reported that the warranty company is holding things up. I haven't heard of any recall on these mirrors, but perhaps there should be one.

I have the same issue on my 2020. Only the driver's side, I noticed when the truck is parked on the street and slightly on an angle leaning towards the curb. Mirror doesn't want to open. I've taken it to the dealer obviously they can't duplicate the problem. I've showed video to the service advisor and nothing. It's hard to leave the truck for several days, it's my only vehicle.

My neighbor down the street has the same truck with same issue.

My problem returned. I manually reset again after getting the car washed, and I have been folding them in and out every time i park, since than its been working fine.

An aftermarket company making a mod that improves the visibility and actually works would have a brisk business I suspect. These mirrors are my biggest complaint about my 3500hd. Luckily I don’t have to fold them very often, but i hate the way they block my view at intersections and entering roads from a driveway. I sure wish I could have bought the non-towing 2500 mirrors on my 3500. I may look at a conversion if it’s close to plug and play.
