Condensation in headlight assembly

I have a 2015 GMC Yukon with condensation in the right and left front headlight assemblies. My turn indicator stopped working which usually indicates a burned out bulb. I did not notice the condensation and I took my Yukon to the dealership for what I thought was going to be a simple bulb replacement. The headlight assemblies are completely sealed which requires the replacement of the complete lamp assembly if a bulb filament burns out. The dealership told me the bulb malfunction is likely caused by the condensation. Since my visit to the dealership yesterday, the turn indicator has worked intermittently. A call back to the dealership with the update and the response was that the condensation likely caused corrosion and still needed to be replaced. They advised me the other headlight was likely to malfunction as well. It is obviously an ongoing issue since the technical service bulletin was modified to include 2016-17 models. GMs technical service bulletin notes that if certain conditions are noted (such as in my case), the replacement of the lamp assembly may not correct this condition. The condensation covers the entire lens. I live in Florida and there is little temperature differential and we have mid to high humidity most of the time. The dealership quoted me $1256 for parts and labor to replace the headlight assembly PER SIDE.

There does seem to be an issue with headlight assemblies.

 

The housings are not "completely" sealed. Yes, you can replace the high and low beam bulbs (unless you have the HID's, looks like you don't). They would need to replace the entire assembly if a part or all of the LED running lights burn out.

 

 

That said-

Remove the bulbs from the housings and park it in the hot sun somewhere (or use a blow dryer) to let the moisture escape and dry the housing out. When you go to remove the bulbs, you will first have to remove a cap, with a 1/4 twist. The cap has an o-ring on it, make sure it's intact, no nicks or tears. This is what SHOULD be keeping moisture out, ha!

 

This happened on my wife's Camry. Actually, no visible moisture but over time the projector lense developed a haze. The only cure was to replace the complete housing assemblies (on my dime, warranty was up). Ours will probably develop a haze as well. Let's hope to nail this down soon...

 

 

(On some forums, some were actually separating the Camry headlight assemblies by cooking them in the oven, at low temps, for a few minutes, to clean the lense. I tried it on the old headlights after I swapped them for new, it was a huge mess with the sealant and stuff.)

After thinking about this more, I began wondering...

 

 

In the TSB, it specifically mentions people trying to get warranty on aftermarket headlight assemblies THAT HAD MOISTURE IN THEM.

 

Either GM buys their assemblies from the same place as the aftermarket companies do (quite possibly) or EVERYONE, with these style of assemblies is having the exact same problem.

 

 

Hhhmmmm...

Same thing happening with our 2015 Tahoe.  Apparently the extended warranty states that it is not a defect even though neither headlight or turning signal works.  About to go ballistic with Chevy and warranty company as I'm being told it will be $2,000.00 to replace!

So our 2015 Tahoe has the same issue.  Dealer quoted $1200 to replace ONE STUPID headlight.  Turn signal won't work - giving inop error.  Dealer sold me extended warranty last time I visited and this time said it's not covered.  Go figure!  Dealer says the part is $800!  I found it on gmparts site for $450.  WTH.  NEVER buying another Chevy vehicle! POS!

We fought with the dealership we purchased it from used and they basically did the work at cost because nobody would cover it.  GM still says it is not a defect!  My last GM vehicle, I can assure you.

Freakin' unreal!  Thanks for the reply.  I think i'm going to get an F-150 crew cab instead as we pull a travel trailer once in awhile and F-150 seems to be a work horse when it comes to pulling.

Hmmmm. All these "New Member" posts criticizing GMs. I wonder how much they are being paid. Probably as much as the MSM sites pay their posters.....

lol I feel i'm paid pretty competitively but certainly not to come on here and post (would be nice though.)

BTW the latest is i've sent a complaint to GM customer "care" and they called and told me someone would be in contact with me, and then they somehow magically started calling the wrong number and even after I gave the correct number, called and re-iterated the same wrong number in another e-mail yet again.  Feels like i'm talking to a robot.  Now they aren't trying to call anymore so I'm guessing they probably closed my case due to their multiple mistakes and lack of care.

I happened up on this thread because we began experiencing the exact same issue of condensation in the headlight of our 2015 Suburban.  I haven't taken it in for repair yet but it would be unbelievable that GM would not own up to this.  With so many experiencing this, it has to be a defect...

I have a 2015 Yukon.  Same issue with DRL on the passenger side.  Dealer told me condensation and $1200 to fix.  I ordered the part from carparts.com and paid $650 plus shipping and tax....took it to a mechanic to install, he charged me $200.  SAME THING IS HAPPENING with the NEW HEADLIGHT assembly SO CLEARLY that isn't the issue and now I'm out $937 and still doesn't work.  WHAT A POS...I will never by GMC or American again which is a darn shame.

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.

      Oil Consumption

      By PunchT37 · Posted

      1/2 qt over full ain`t gonna hurt $h!t. Most times, a whole qt won`t either. Most have windage trays now. As long as the crank isn`t slapping itself in the oil, it`s not the end of the world.   We used to overfill 1 qt at the track, at race time. Better to have it over full than having the pan sucked dry at 6500 rpm`s.
