UPDATE: Couple Mechanical Questions - Active Tuned Mass Module & Rear Window

[Ram20Limited]

Hi

I have a 2020 1500 Limited.

Two things going on - first is the rear window leaks slightly in the car wash. I have an extended warranty hoping to get it covered under. What piece typically fails that causes the leak? There is an exclusion in my warranty for interior and exterior trim and molding that I'm worried they will try to refute under.

Second is a message periodically popping up "Service Active Tuned Mass Module". It leaves no code or stored message and nothing is noticeably going on with the truck. Any ideas here what this is and how to guide the shop to fix it with warranty?

Thanks!

The rear window frame cracks, (emphasis in frame) should be covered under warranty.
Tuned mass module, not sure about that, could be related to possible water intrusion to the RF hub from the leaking rear window frame?

Thanks for the reply. Yea I know nothing about the Module or how to approach that but it is annoying that it keeps popping up about every 50 miles or so.

If the rear window is the frame then yes by the letter of my warranty that should be covered.

Update:

Service center couldn't get more information on the message. They said to go to the Ram Dealer itself (I bought it at a Mazda dealer used)

Update for anyone interested/experiencing this:

Ram dealer read 20+ modules with low voltage errors.

This was all related to the truck battery dying recently.

Also it was the third brake light leaking which was obviously covered under warranty.
