I have a 2008 Acadia SLT without hid headlights, so I ordered some matrix diamond style headlight bulbs H11's back in June 2008. March 1st 2009 the driver headlight assembly was foggy on the inside and over time it got worse but the light bulb still worked. I took it to the dealership and they ordered a new assembly thinking it was water. March 28th 2009 the driver bulb went out. March 30th I took it in and they took the assembly off the vehicle and said it was fogged up due to the connector on the back of the bulb burnt up. Now i have to buy a new assembly because they said it was due to the bulb i put in and it voided the warranty. I can’t believe this due to the assembly was fogged up and the bulb still working for one month before the bulb went out. Is this normal, no where on any website does it recommend to upgrade the wiring harness for aftermarket lights? I have the same bulbs on my camaro since 2002 and have had no problems. Why did this happen on a new car and why did it take 8 months for it to happen?
