I have had to replace the headlight bulb and the day light bulbs 4 times since January. Each time I replace one the other goes out and it does't last longer than a few weeks. This is very dangerous and stressful as the headlights went out on me as I was driving home two nights ago and the road that I take to get home is very dark. Also, I had to replace the multi function switch (windshield wiper switch due to it only working on high speed) in January. I've noticed multiple people with the same complaints. Please fix this problem as buying bulbs are becoming expensive as well as the time it takes to get them replaced can be lengthy.
