You ballasts are just crap from China, that's why the igniter portion of them won't fire up the bulb properly each time like it should. Get yourself some Morimoto's from TRS and call it a day, along with their XB bulbs too if you want decent cutoff and hotspot positioning. The car uses 55watt halogen bulbs as stock, so no, 55watt HID ballasts won't "draw too much" power from the system. Though 55 watt HID tend to burn out quicker by about 20 percent when referring to the bulb's lifespan.
