2012 GMC Acadia: headlights failing or too dim

Filed Aug 5, 2026 · Airbags, Electrical · PA

Hello so I notice 3 weeks ago my headlights keep cutting off and on then a week later my radio stopped working, The floor of the driver side is always wet after it rains. I noticed one day the rain started dripping on my feet when I drive after a big rain fall, I believe the car is not sealed properly and now water is coming out from the airbag signs in my vehicle and the car starting to smell like mildew. I think water is sitting in certain parts of my vehicle. I'm not sure what to do.

The headlight assembly's are melted and headlights don't work. Seems this is an ongoing problem with gmc headlights in years past that they continue to not address. I am furious that despite reports and recalls on this issue from many years and many makes and models they have not addressed and continue to avoid recalling all vehicles with this garbage headlight assembly, that causes headlights to fail and increases risk of car fire. I want this repaired by this garbage company and something done to make them stop utilizing these unsafe and faulty assemblies.

My low beam head lights keep blowing over the past two years, I have had to replace them 5 times on the driver side and 2 times on the passenger size. Also had my head light harness replaced oct due the blub breaking in multiple pieces. Jan of 2019, it rained and my turning signal blub broke again and the lighting component filled up with water and looked like a floating fish bowl.

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.

I have had to replace my low beam headlights either the driver or passenger side every week for the last month. There was a special coverage adjustment #14823 released by gm on may 12, 2015 and I was told by gmc I needed to make a complaint to try to be eligible for special coverage. There is clearly an issue here and definitely a safety problem. I can't see having to spend over $1000 to replace the headlamp assemblies for a known problem
