I have a 2025 GX 550 with factory installed rear cargo compressor. The air compressor itself works without problems. The 12 volt and USc ports did not work from the factory, no power despite the engine running and power turned on to the panel. I took it to the dealership and they replaced the complete unit saying there was a fault in the unit.. I confirmed the USc ports worked before I left the dealership. About a week later, I connected to the 12 volt power outlet on the panel with the engine running and the power on to the panel. It worked for about 10 seconds, then went dead again. The air compressor itself still works. It is just the 12 volt power supply and the USc ports that are dead. Has anyone else out there had this problem.
