1 Fog Light Switch problem of the 2015 GMC Sierra

Failure Date: 01/16/2016

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. I personally nearly hit a pedestrian during a rainy situation, and also feel unsafe operating this vehicle at dark.

2 Fog Light Switch problem of the 2014 GMC Sierra

Failure Date: 11/23/2014

Poor lighting with headlights. Can barely see what is ahead at night. Seems like this could be very dangerous, and I feel unsafe driving at night, especially in the rain. Turning on fog lights helps a little, but you shouldn't have to constantly run them. Bright lights don't help much either.

3 Fog Light Switch problem of the 2014 GMC Sierra

Failure Date: 11/09/2014

I purchased a 2014 GMC Sierra in November of 2014 and the headlights on our truck give you very limited visibility, it is unsafe to drive at night with high beams or low beams, I use my fog lights to help me see better but they do not help much on distance. I traded in a 2013 silverado that had awesome headlights for this truck and raised my payment 300$ only to have a truck that I cant drive at night. Something needs to be done about this. I have read many complaints on this issue and feel that gm needs to correct it as soon as possible before a serious accident happens.

4 Fog Light Switch problem of the 2014 GMC Sierra

Failure Date: 08/23/2014

Headlights in normal operation situation are woefully short of illumination distance and easy to overdrive at highway speeds. High beams and fog lights are more adequate, however high beams cannot be used in traffic and fog lights tend to irritate oncoming drivers on highways in smaller vehicles.

5 Fog Light Switch problem of the 2014 GMC Sierra

Failure Date: 08/03/2014

The headlights in the vehicle are very dim. They have a projector light in them and only have one bulb, they projector moves when switching back and forth between bright and dims. The problem is there's one little yellow circle out in front of the truck about 30 feet, the brights do absolutely nothing, and there is no lighting to the sides of the truck. There is no light on the curb and making a turn is not only difficult but also unsafe. The vehicle has been in 3 times to fix this issue and they have done nothing to help. I read online that there is an update that sends more voltage to the headlights but they also know nothing about that. The last time they said they wouldn't even align the lights because I had put aftermarket bulbs in just to be able to see. The fog lights are twice as bright as the headlight, I've told them that, called their customer service number, told them that, and they don't seem to care. I see online that it is a common complaint and something needs to be done about it. Also the ones like mine with the vibrating safety seat get loose, also a common complaint, and they won't cover it under warranty or recall.

6 Fog Light Switch problem of the 2014 GMC Sierra

Failure Date: 06/30/2014

The headlight performance on this truck is the worst I've seen in any vehicle, but for a truck, I cannot believe they are allowed on the road at night. The owner's manual states they are factory set and do not need adjustment. That information was obviously not checked during the quality check or checked but felt it was as good as it gets. On high beam, the driver's side light is pointing so far up, it's in the trees and above the road. The right side high and low beams are inadequate for all purposes, especially seeing around curves and turns. You are literally blind on a dark street, even with the fog lights. Very poor illumination of the road. I've taken it in to the dealer for adjustment and they did not change anything. This will be the last gm product I buy since it seems the last three vehicles I've owned had issues that could not be resolved. And I am a member of the gm family. For the price of these vehicles, they should be top quality. Gm should be ashamed of the quality they deliver to customers for vehicles priced over $45k.

7 Fog Light Switch problem of the 2014 GMC Sierra

Failure Date: 12/10/2013

Headlights are a safety issue with this truck. Can not see the sides of the road and the roadway is very dim. I have contacted gm many times with no answer to the problem. One time they said, turn on the fog lights when you are about to turn a corner.

8 Fog Light Switch problem of the 2014 GMC Sierra

Failure Date: 10/01/2013

No accident. (yet) head lights are pathetic. Range of vision at night is totally unacceptable. There is no diffusion of light. Only light is on a straight horizontal line. Causes a very tense driving situation on any dark road. The lighting on the periphery is virtually non-existent but marginally improved if fog lights are left on all the time. Many complaints have already been filed. Cannot understand why GMC has not been compelled to have a recall to come up with a real solution. It does not appear to be a question of adjusting the current lighting arrangement. This should be a priority recall. Dangerous to drive vehicle at night.
