Anyway, the HID kits are bright, but it does take a while to warm up, much slower compared to my stock even with the upgraded ballast. The other thing is, every once in a while, I get a left fog light dash error in my car. It comes and goes. I wonder if my unit is defective or something... Anyway, I've only had it for the day, so we'll see how it goes...

I just noticed that my left and right fog light reflectors reflect different patterns...I wonder why.
You need to ensure you have a solid ground.... Metal on metal, no paint. Also ensure everything is seated fully. Anytime errors are shown they either show cause the units dont work (at all), or there is not a good connection. In this case I think you answered your own question with the ground problem perhaps.

IF its only one side, that is the side you need to ensure is getting good connection.

You could also swap ballast, if the problem stays on the left, then you know its a connection issue. If the problem goes to the right, then it may infact be a defective unit (highly doubtful but still possible, not a perfect world).

The left side and right side (housings) have different reflections for a reason; This is because you dont want blind oncoming traffic so there is a bias down and in on the driver side lights.
