Odometer rolled back 25k

[TMFB8425]

Has anyone experienced the odometer rolling back 25k miles from unhooking the battery?!?!

 

I installed an amp and subwoofer on my 2021 5.3 Trailboss LT (no Bose). When everything was hooked up and battery connected my display odometer read exactly 25k less. It has been a week and has not reset itself. 
 

What do I do???

has your truck been serviced at the dealership, go to service and explain what happened and maybe they have a solution. have them hook up the truck, this will show you have not tampered with it

Woah. That's weird. Mines going in this week for the subwoofer/amp install from GM Accessories, but I prepaid them to install it for me using the 20% coupon to basically pay for it. I would think it's weird that those 2 things are associated. Is it possible?

You smile and move on.
