2015 GMC Sierra 1500: headlights failing or too dim

Filed Aug 13, 2025 · Lights · PA

Headlights on this vehicle, since purchased, have not cast enough light in order to see in unlit backroads, or extrememly dim areas. I have to drive with my brights on constantly, in order to get enough light thrown onto the road, for the left and right sides, as well as the front. These were not working well since purchase. I took my child to a friends house in rural PA, and I literally could NOT SEE THE street signs, let alone far enough down the road. I nearly hit a stone wall.. My eyes keep asking to see more, but truck does not produce enough headlight. I even went to the eye doctor, after that situation, thinking it was my vision dimming, but was told I have 20/20. There needs to be a formal recall. I am not the only one complaining about these HORRIBLE projection headlights. To replace these headlights would cost over 1000K, out of pocket, which is not something I should have to fix. I am complaining now, because with the light getting darker earlier, am noticing how lousy driving at night really is.. and honestly, being BLINDED by oncoming LED's , without having proper headlights on my truck in order to see when blinded, really [XXX]. Please address these [XXX]. Make headlights great again! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Lack of illumination of headlights straight ahead. No light shines to the sides of the vehicle making it difficult to see left or right when negotiating a turn at night. I have put new bulbs in both sides the best money can buy at CarQuest with no improvement. The headlight lenses are not dirty or fogged over. It appears to be a design problem, and I have seen other people with this model truck complain about the same thing on some blogs. I contacted GM directly looking for information I can get on a possible upgrade, and they have offered not solution. I have had this issue with this vehicle since buying it used 4.28.2018

Headlights are so dim because of the plastic cover that is made into the OEM headlight assembly. The plastic apparently had no UV protectant and the plastic has turned dingey yellow and clouded where it's affected the light output from the vehicle

The stock headlights both low and high beams provide poor lighting at night. The headlights provide a poor beam pattern making it incredibly difficult to see more than 100 ft in front of you while driving down dark roads. And even more difficult in light storm conditions both rain and snow. The high beams aim too high when used and don't show enough of the road in front of you but rather the tops of tree's or other objects instead of the road. The low beams don't provide much light on the sides of the road as well and at times feel more like they're just fog lights with the amount of light that is put out. These incidents happen anywhere from low speeds up to highway speeds. I have noticed this issue since purchasing it used and have seen multiple similar complaints online.

This vehicle has poor headlight performance. I changed the bulbs to no avail. There is no way this 2015 GMC passes vehicle state inspections if they really look. There is very little power to the lights, even on the high-beams. After some quick research - GM has a service bulletin PIT5374 that addresses this very issue. But the dealerships are using this safety defect as a way to generate service volume. Requiring a $170.00 diagnosis to identify a problem they already know exists.

The headlamps on my vehicle have been very poor, both in low and high beam positions ever since I purchased the vehicle. Thinking that their must be something wrong with the existing headlamps, I purchased the replacement bulbs and there were no improvements. When driving at night I have to stay on low beam with the fog lights on just to help to see. I can't use my high beams at all because the lighting is so poor. Gmc is aware of their headlamp issues on the 2014 and 15 models but nothing is being done about it to my knowledge. Without spending $500-$1000 to change them over to LED, is there anything that I can do to improve this situation?

While driving home the other night both headlights failed at the same time. Lost both high beam and low beam. Tried everything to get them on with no luck. Interment panel showed that they were still on. This was very scary and dangerous as I has traveling on a major highway. Luckily I had fog light to give me some light to gt off the highway safely.

While the head lights and fog lights are on, the right head and fog lights are dim but the left head and fog lights are bright. Also the right turn signal shows error message on the cluster that the bulb needs to be replaced and you can hear it blinking fast, but when I exit the vehicle to inspect the signal I notice that it is not blown and it works fine but I still get the error message and the fast blinking. Both stated problems occur while the vehicle is stationary and when the vehicle is in motion.
