Recreational Vehicle Lpg Tank Valve/gauge problems of the 2008 Infiniti G35

Two complaints. 1. The dashboard in my 2008 G35 is melting. It has a tacky feel and is easily damaged when touched. Many cracks in the dashboard. At times the shiny appearance of the dashboard reflects light on the windshield and makes it difficult to drive. 2. The sunroof has drain channels for draining off water that accumulates around the sunroof. The drain channels are plastic pipes that run through the a-pillar and spill onto the roadway underneath the vehicle. The drain channels are breaking apart at approximately dashboard height and water is injected behind the dashboard and is shorting out the vehicle controllers. While driving in a storm on a city street my instrument control panel starting blinking and eventually failed (e. G. My whole instrument panel went blank). Water destroyed my bcu and the car electrical system has never been the same. Replaced the bcu and drain channels. However, the electrical system has never been the same. Still lose certain instruments, e. G. Water temperature gauge, and intermittent sounds of relays trying to recover lost systems. Constantly getting false indicators of failures on the dash. It would have been frightening to have lost my instrument cluster while driving at night.
