Out of the last 8 or so times I've started my car, about 5 of them have resulted in a malfunction of the LCD screen. The LCD shows the graphic of the four wheels, and the wheels seem to turn when the car moves, but the battery indicator remains white and no moving arrows come up to show the engine or electric motor are engaging. The car drives fine with no dash warning lights or anything. If I press the consumption button, it does not beep (very odd), but switches to a blank consumption screen with no instantaneous MPG readout or any other info. Pressing climate button does not beep, and says "Check the connection of the air conditioner." with nothing else displayed. Yet I can use steering wheel controls to turn AC auto on (dash light turns on), turn on defrosters, etc. Pressing the audio button says the audio is off, even if I turn on the stereo using its power button.
So far, this only happens when I first turn the car on. It has happened on a cold/damp night (11:30pm) and on a hot dry day (very hot inside the car, in the sun, 5pm). After about 2 to 6 minutes, so far, it has always fixed itself and everything goes back to normal. This fixing itself has happened both when the car is moving, and when I have been staring at it in the parking lot. When it does fix itself, if the stereo or AC were on, they both turn off. Once the LCD starts working, it has not yet stopped working until the car is turned off and on again (including on a couple 2 hour drives). However, once, while I had been driving for 10 mins or so with no LCD problem, the AC and stereo both turned off as if the LCD had done its reset thing, though nothing on the LCD changed that I noticed.
Anyway, I haven't been able to find anyone else with this problem, so it's probably unique, but I thought I'd ask if anyone else has seen this or has an idea what might cause it. If it's just a loose connector, maybe someone knows which one so I can check it. Otherwise, I guess I'll have to take it to a dealer. The car worked fine for about 8 mos before this started, and I didn't do anything to precipitate it like washing it or going out in the rain.
