GMC Yukon Denali headlights problems

Filed Sep 30, 2018 · Electrical, Lights · 41,000 miles · FL

Drivers and passenger brake light go out intermittently. Passenger stays off for long periods of time. Looked into replacing no idea if it will fix the problem. Cost at least $500. Each parts only. I have seen so many other vehicles like mine same problem. Headlights also going out, water inside of cover. Led and turn signal went out on drivers side replaced for a cost of $900.00, (just for the headlight) again no guarantee it will keep working. Also battery went dead replaced battery. New battery also went dead. Car alarm went off the night before battery dead in the morning. Has been in the shop 3 weeks now. Same thing happens alarm goes off kills battery. Shows massive drain and set about 32 codes. The drain doesn't register after that. Recharge battery car is not running when this happens. Problem repeats every time after charging the battery. Something in the wiring is shorting out. Tested both batteries they both test good. Afraid of what will happen next with the electrical on the vehicle. Not sure if the lights have anything to do with this or not. When ordering headlight and asking about brakes told by dealer parts they sure are selling a bunch of these. I have had people driving down the road stop me to tell me my brake light is out. I did not know that the turn signal on the front was not working until a car pulled out in front of me while waiting to make a left turn. I got out and looked at the light and it was not working. I cannot drive the vehicle at all because it keeps draining the battery. I have a ase certified master technician working on the vehicle in a reputable shop.

Daytime running lights and low-beam running lights suddenly became inoperable on 1/15/17 (est. ~150k miles). This was noticed during the day, so safety risk was minimized, but the vehicle is now inoperable during the evening (although high beams are still functional, as well as park/blinkers). Http://m.gm.oemdtc.com/recall/rcsb-15v519-4439.pdf there is a may 2016 gm issued recall affecting similar vehicles with years 2005-2009, but gm said my vehicle is not currently on the list. I requested information to evaluate my vehicle time for addition to the recall and they initiated a vehicle complaint # 8-2672247033 on their end. They also pointed me to this website to file with nhsp, so that I could file this notice to better determine if this recall should be expanded to other gmc models within 2005-2009. I need to verify if the pn# for my headlamp driver module (hdm) is also [13506836]. P.s. The title of the gm recall for similar vehicles is "14291 low beam headlamps and daytime running lamps (drl) could fail to illuminate". The other associated references are: * reference number: n140291 release date: may 2016 * gwm number: 140291 revision: 00

Headlights do not illuminate the road far enough to allow safe driving. Took vehicle to local dealer and they checked the lights and said they meet manufactures specification. When driving on country road with no other illumination the headlights do not project far enough to see what is ahead. Driving at posted speeds 55 to 60 MPH cannot see what is coming up. Have to use high beam in order to see far enough to be safe. Did an online search and found that this is a common complaint for this model year.

Truck started to have major eletrical issues. Blubs burning out often sockets burning out had to replace too often. Light covers melting. Headlights out and will not come back on for days, have to tap them to get them to come back on. Horn blows from alarm all times of the day and night. Inside lights on dash, steering wheel and doors will not work at times all lights are not functioning correctly. Lights at times too often will not work at all. Stability warning light comes often. Afraid truck will catch fire from the electrical issues.. Please help!!!!

Passenger headlight (low beam) has been replaced twice. Intermittently goes on and off. Same with 2 out of 3 brake lights. Doesn't matter how many times we replace the bulbs, we keep having the same problem. Is gmc going to pay my ticket when I get pulled over?

I have had multiple ongoing electrical issues with this vehicle. Starting in 2005, the exterior electronics (I.e. Signal lights, stop lights, head lights, etc) began to malfunction. For example, I would trigger the signal for one direction and all of the signals for all directions would trigger... Even pressing the brakes triggered all of the exterior signals. The dealer had a hard time isolating my problem, but after several visits, the dealer was finally able to diagnose and rectify it... They isolated it to a junction box where all of the electronics terminate. However, by this time, my vehicle was out of warranty, so I had to cover the costs for repairing the problem myself. My most recent issues, which, by the way, seem to be common issues, are triggered by a message stating, "reduced engine power". This particular issue does not always render the same results... Sometimes the vehicle's speed will significantly decrease to nearly a halt, but other times I may just experience increased idling of the engine, even if I am at a complete stop. My understanding, according to hundreds of reports that I have read on the message boards, is that this issue is caused by either a wiring harness that leads from the accelerator to the throttle body or it's a defective throttle body altogether. I have experienced intermittent electrical problems with my windows as well, but this appears to be a minor issue when compared to the other two that I addressed above. I will file a formal complaint with gmc corporate office today and see where that goes.

Headlight flicker had dealer work on it and replace one headlight but this did not correct the problem. Dealer said this was normal. Notice the flicker when I go over bumps or when cornering to the left.

After noticing that my 2003 yukon denali had intermittent headlights/dash lights dimming, I took the vehicle to my local dealer to have it checked out. They presented me with a document that stated the gm stated this was not a malfunction and was a normal condition. There is nothing about this that is "normal". Any time, at night, a curve is taken at above 35 MPH the lights flicker. I had already pinpointed that it had to do with the vses system because when the vses is turned off, this does not happen. When a curve is taken and the flickering occurs, the voltage meter for the battery drops substantially and then goes right back to normal. This is a distraction for the driver (myself), any oncoming traffic, and anyone that I am behind. This absolutely needs to be looked into before it causes injury.

When adjusting the steering wheel during night hours the headlights would flicker. The dealership was notified, but did not resolve the problem. Please provide more information.

Head light flicker while driving and turning or going over bumps. Appears to make drivers think I am flashing my high beams. Dealer could not duplicate problem. Very distracting while driving, not only to me but people who are ahead of me. Dealer was not very concerned about problem and sent me on my way. I feel like this is a safety issue and should be taken care of. This is not an intermittent problem, it happens every time I drive at night.
