NHTSA Complaint #11653987 — 2024 CHEVROLET SILVERADO 2500

While towing our 25ft travel trailer, I began getting warning from the trailer brake controller which repeatedly disconnected and, thankfully reconnected them after a brief interval. Luckily, the times when I had no trailer brakes did not require rapid stops. That said, towing a 7000 # trailer thru the mountains in a driving rain storm with no brakes randomly caused a bit of concern. After researching this I find this is a known defect and has TSB’s and voluntary recalls in place. (TSB 23-NA-149 and N232414840 respectively) However I was never notified by GM as my VIN was not included in the above. We could have been seriously injured or worse. This tsb is almost 2 years old. Why were we not informed/included? Our issue is identical to the tsb.
