2015 GMC Sierra 3500 Owner Comments

problem #4

Sierra 3500 LSE 6.6L

  • Automatic transmission
  • 93,206 miles

A D V E R T I S E M E N T S

All my life I have owned GM and Chevy products but wish I would have done more research on my 2015 3500. I do a lot of night driving in some extreme roads and weather. The head lights are absolute JUNK and all the dealer could say was; oh well, we upgraded them on the 2016. Now we can't keep bulbs in them. If my 2013 would have still been on the lot I would have taken it back.

I have looked over some other complaints on here and fully agree that someone will have a serious incident if not so already. I have had some very close calls and don't even ask about high beams. I agree that GM needs to do something about this problem.

IF SOMEBODY STARTS A LAWSUIT ON THIS, COUNT ME IN.

Sierra 3500 Denali Diesel

  • Automatic transmission
  • 1,000 miles

ALMOST THE PERFECT TRUCK, 3500 DENALI WITH EVERYTHING/LOADED. FROM THE NIGHT OF PURCHASE, MY WIFE AND I NOTICED POOR VISABILITY ON BOTH LOW AND HIGH BEAMS. OUR TRUCK IS EQUIPPED WITH "PROJECTION LED BULBS". THEY ARE HORRIBLE AND TO THE POINT OF BEING DANGEROUS. HAD I KNOWN OF THIS DEFECT PRIOR TO PURCHASING THE VEHICLE I WOULD HAVE NEGOTIATED AN UPGRADE. I REALLY LOVE OUR TRUCK BUT CANNOT FATHOM A VEHICLE ENGINEER DESIGNING SUCH A POORLY DESIGNED LIGHT. MY WIFE JUST RESEARCHED THE ISSUE ON ANOTHER SITE AND FOUND THIS IS A VERY COMMON COMPLAINT.

Sierra 3500 Denali Duramax

  • Automatic transmission
  • 17,000 miles

I bought the top of the line GMC truck and I can't drive it in the dark. The low beam is dim and then when you go to high beams you have no more candle power just a shutter lifts and the lights go dimmer. I have stated this to the dealer every time I go in, but they act like they have never heard of it before. I come home and type in poor headlights and the whole world is cursing about them. SOMETHING NEEDS TO BE DONE I could shine my mag flashlight out the windshield and see better. I don't want to put in an after market headlight system because it is a different voltage. Step up GM and fix the problem. Does any one know if you can put a 2016 system in a 2015?

problem #1

Sierra 3500

  • Automatic transmission
  • 50 miles

When driving road with lots of ups and downs, cannot see ahead in 'Low Beam' when I'm in the dip at the bottom. I live in area where there is lots of critters on the roads at night.

Dealer suggested I try an after market fog lamp upgrade. When I did, fog lamps stopped working at all. High Beam not that great either. I haven't yet had anyone flash me to turn of High beams. Frustrating problem. Wondering if anyone has heard of a fix/upgrade ?
