Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The projector headlights are inadequate on a level road, and are dangerous on rolling terrain roads and curves. They could be possibly designed for stationary use in a perfect enviorment but not for moving vehicles, I cannot safely drive this vehicle at night, I fear not only for myself but for other people on and near the path of this vehicle. My mind is clear, there are many blowing the whistle.”

NHTSA complaint #10860170, filed 2016-04, 200 miles

“Headlight performance is very poor with weak yellow beam both on low and high beams. Difficulty seeing during night driving, especially at highway speeds in dark areas, is very hazardous, even worse during rain. I am concerned about my safety and that of my family while driving this truck at night. The projector-style headlamps on the vehicle were dim with a yellow color and provided inadequate front and side illumination. The headlight aim was raised, which resulted in little improvement.”

NHTSA complaint #10850161, filed 2016-03, 37 miles

“I purchased this vehicle new august 2015. The headlight projection and illumination on this vehicle is extremely poor especially during wet roads or raining conditions. I have to use the fog lights at all times and still do not have adequate lighting. I feel this situation can and will result in serious injury or death due to lack of proper lighting. I was appalled to find out general motors only use a single halogen bulb instead of a dual filament lamp or a combination low and high beam lamps. …”

“Projector headlights on 2015 Sierra is very dim compared to other vehicles. Tried adjusting but did not help. Very poor visibility in unlit dark roads and streets and poses risk. I tried bringing it to the dealer but they could not do anything about it. I mentioned several complaints from other owners including a class action law suite that was filed in california in october 2015. Unfortunately, there are no other alternatives with the exception of purchasing aftermarket headlights. I would like Gmc to fix this known problem. …”

NHTSA complaint #10850003, filed 2016-03, 25 miles

“The head lights on this truck are of poor design and are very weak. The lights do not adequately light the road ahead or the shoulders. They will become a contributing factor in crashes and deaths unless they are improved! I can't believe these headlights would pass the minimum standards for illumination if follow up testing is done in poor weather conditions.”
