GMC Sierra 3500 headlights problems

Filed Oct 18, 2026 · Lights · UT

Headlights are prone to get water in which shorts out a module and loss of headlight. Happened tonight while driving in the dark. Flickering occured in the driver side as the passenger side failed a few nights ago. Seeing a trend online of others having the same problem. Loss of lighting at night is a severe risk of driving at high speeds

Hello, I purchased my 2024 GMC 3500 AT4 Seirra late October 2023. Since the purchase date, I have been informed by motorist while at intersections my tailgate was down. I thought I was doing something wrong. On 3/3/2024 I was preparing to wash my truck and noticed my front amber lights were on surrounding my headlights. the vehicle was off, and my keys were in the house. Then my tailgate opener activated on at least 10 - 12 times. The tonneau cover is tight so the tailgate can need assistance opening. Nevertheless, the tailgate has opened on a number of occasions and my two front amber lights came on at least once. I reported this to my dealership on [XXX]. they said my truck has not been recalled yet but to watch this and if it progresses to call them. I noticed a small dent in the top rail of the tailgate on [XXX]. I have yet to put anything in the bed of the truck or even install a hitch in the receiver. I believe the tailgate had to be bumped when it was down by another vehicle, and this is absolutely related to the tailgate malfunction. since I haven't used the bed of the truck. Moreover, I feel GMC should be held responsible for the repair or replacement of my tailgate.

While driving on the highway at night during mixed precipitation/icy conditions I noticed I was loosing visibility. I had to pull over on the highway to see if my headlights were on. I discovered they were completely covered in 1.5-2in of ice. The entire front grill of the truck was covered in ice. I had to chip off the ice on the headlights so I could see. I had to pull over three times during my 2hr drive to scrape the lights just so I could see! The headlights on the 22 model have shape, not straight or a smooth curve like prior models, which is part of the problem. Although, it was strange how the entire grill was covered in ice. I have always owned GMC or Chevy trucks and have never had anything like this happen. I wish I took a picture to send in but I didn't think of that in the moment. This is absolutely a safety hazard. I hope in the near future there will be a recall to have this issue addressed.

Hid headlights on my truck flicker significantly, and dim and brighten, while driving vehicle on bumpy surfaces. This is brand new truck with 2500 miles on it. I paid extra for the all terrain version. Gmc's official response to me is that it is normal for hid headlights to flicker on/off, and they are refusing to do anything about the issue.

Headlights shake or flicker at the slightest bump or crack in road. Gm is aware of the problem but has no fix nor do they plan to.

Headlights not bright enough to see in the night

Filed Nov 20, 2017 · Lights · 36,000 miles · RI

Headlights on this truck have always been weak, distance is not lit up and in rainy weather on the highway is very poor even with fog lights on. The help from the fog lights is minimal. This is a known problem by the manufacturer and is repeated many many times on various gm related owner forums. This is a safety issue and needs to be addressed and corrected by the manufacturer.

Lighting is very poor, hard to see at night. It's not safe to drive it at night. When it's raining if headlights on its fogging up from inside.

I am afraid to drive at night because the head lights are terrible. I couldn't see the tire carcass left on the highway early enough to swerve around it. I hit it with the rear wheel and did approx. 6000.00 dollars damage to the vehicle.
