NHTSA Complaint #11690268 — 2024 GMC SIERRA 3500

My truck is experiencing the Brake Controller failures as documented in GM Bulletin N232414840 - Customer Satisfaction Program Intermittent Loss of Trailer Brakes. This problem has occurred several times over the past year. I thought it was the wiring on my trailer - so I checked and found no problems (plus it works properly on other tow vehicles). Additionally, the problem resets and works properly after turning the truck off and back on (resets the system). It then works properly until it unexpectedly disconnects again. I thought the problem was unique to my vehicle until I got online and discovered that this is a known issue for others as well (2024 GM HD trucks). I contacted my GM dealer (and GM's customer satisfaction center as noted in the bulletin) and they informed me that my truck is not covered under this recall (not one of the covered VINs). I told them that I'm having this issue and they told me to report the problem to the NHTSA. Needless to say, GM has not included all the applicable vehicles in their recall (like mine) and I need the issue corrected before it causes a serious accident.
