NHTSA Complaint #11609553 — 2020 CHEVROLET SILVERADO 3500

We tow a 2024 Grand Design Solitude 310GK with our 2020 Chevy Silverado 3500 diesel truck. We are getting frequent but intermittent loss of our trailer brakes during towing. As you can imagine this is a serious safety issue. We will be towing and receive a message on the display "Trailer Brakes Disconnected" then typically followed by "Service Trailer Brakes". This has been happening more frequently over the past 3 months. Imagine driving down a hill with a 15K pound rv pushing you and there are NO brakes on the 5th wheel. It is extremely scary and dangerous. I've researched on the internet and Facebook and there seems to be a "Technical Bulletin" from GM Bulletin No.: 23-NA-149 Date: September, 2023 recommending the replacement of the Trailer Brake Control Module. I've called to have the dealer replace our brake control module but it is not covered because it is a "Bulletin" and not a "recall". This is absurd and the manufacturer should take care of this known issue.
