I have the exact same issue. I have a 2008 lr3 SE. More information on the problem is that on my main dashboard it has --- for temperature and time and some information wont display. Also, the center console which controls the radio, air conditioner, locks ect doesn't have any power. Also, when this first started to happen, my emergency lights came on and due to no power on the center console, i could not turn them off. The first time i turned the car off after this happened, it will not start. It wont even turn over. I checked the voltage on the batter and found that it was 12.3 volts.
Also, my lights/turn signal works, but doesn't show on the dashboard if they are on or not.
I just tried to do a hard reset, didn't work but noticed a new error. HDC system fault, not available.
I also changed the battery thinking this might be the issue, but it didn't work.
