Driver side rear brake light working intermittently, approx. 10% of the time. Called dealership and said it is known issue with most denali brake lights. Was quoted to replace entire assembly $900. Each side for this known safety issue. This is a serious safety issue and known by GMC with no recalls available.
Passenger side tail light stops working occasionally. This affect's the brake light and night driving. It has stopped working up to a week at a time, but then starts working again. It might be weather related.
Brake light goes in and out and doesn't work all the time. According to what I'm reading is a very common issue and needs to be fixed. There is no fix except buying a brand new one and that doesn't seem right. Seems like a poor design and not to mention I can get a ticket for this. And most important...I have a family with two small kids and this is a safety hazard if my brake lights do not work!
Rear passenger tail light needs to be replaced at a ridiculous cost. Extremely poor engineering design. That is if it wasn't intentionally designed to fail. On the low end $5-600 to replace a tail light"?" what a joke. Sad thing is I'm lucky, many many people have had more than one light assembly go out. I've bought GM for my last 3 vehicles (Envoy, Tahoe, Yukon) this will likely be the last time I ever buy GM.
Brake lights work sporadically, until the passenger rear finally stopped working all together. Contacted the dealership and was told this was a very common problem, that they replace several a week, and my warranty would not cover it. Got a estimate of over $1600 to repair it. Was pulled over on several occasions each time was told it was either the left or right not working. Then miraculously both would be working. If this is such a common problem like the dealership stated, then why hasn't GM recalled or discontinued using them? this is a serious safety issue and not as simple as replacing a bulb. Way to costly to just bring in for repairs!
My tail lights go out every now and then. More in the summer than the winter. The break lights and turn signal still work great. I have looked online and it looks like a lot of people are having the same issue. Its a safety issue having tail lights one minute and then not having tail lights. I asked GM months ago to do a recall and still haven't heard anything. This happens while it is in motion and stationary. We seen online that all the issue is, is a place that comes loose in the tail light and it only needs soldered together. We took the tail lights out and had a professional to solder it and they started working perfectly. They now are working part time again. For this to happen to multiple people I feel like it is an issue GM should fix. If it was rare I would understand if I had to buy new tail lights. But with multiple people having this issue will new lights not do the same?
The A/C has quick working. We took it in to get fixed, they could find nothing wrong except low on freon. Replaced and it is gone (has dye in it & no detection where it has gone). I didn't drive this car for 6 mos. Because of this (too hot). I can't afford to fix everything that is going wrong on this car. Same day A/C went out, the heat system went out on the driver's side seat. Just blows cold air! this is ridiculous! the suspension is now slamming hard and super loud (especially when it is cool/cold out). I am glad they are finally fixing the brake issue but really" all this other bs on this expensive car? the day we got back from shop for the A/C, the driver side brake light was out. Omg!! talk about expensive to repair!! 650-800 for just the light assembly through GMC and that is reconditioned parts! why would we put more crap parts in? waited another 2 mos to save money to go to an aftermarket person to fix this. Just waiting on the other side to go out! lights go out all the time, why would you make them where they are not affordable" we baby our car, park away from everyone and yet it is falling apart due to the crappy products that GM used to manufacture it. All these problems happened (except the braking issue and the suspension) when I went to start the car and I noticed it. The suspension is when I am driving and the road can just have a 'wave" in it. If there is any sort of bounce, this car will bottom out and is super loud.the air started 3/28/19 and all has followed. We bought it used with 74K-ish on it. Have only had it since last July, 2018
Tail lamps, tail lamps tail lamps! non serviceable led illumination bulb circuit is faulty leading to intermittent operation. Having part time brake light is against the law and more important to me, leaves my family in an unsafe situation. Web search leads to many motorist having the same problem as I. as a paying taxpayer we should not be sold faulty goods that may have dire consequences.
The rear left tail light has gone out, which is a common failure mode of this design. The entire tail light module must be replaced, pushing $1000 for a bad design. This needs to be recalled and replaced, as it is extremely affordable and a safety issue that GMC will not address.
Rear faulty brake lights both sides. Quoted 1800 to replace. With a quick search for replacement/fix options I found a single individual that has repaired over 2000 of them. There are many more out there. This seems to be an issue with a high percentage of this make and model and GM acknowledged it by replacing the cope the 2 years later but has refused to recall this. It's an absolute safety hazard that seems to be ignored by
I have a 2015 Yukon denali with about 63K miles. My tail lights do not work properly. The driver sign works randomly. At time it works in the day and night others it appears to only work in night time or when the vehicle is not directly in the sun during the day. Yesterday evening I notice the passenger side was out instead of the driver side. I have went to GMC dealership and they all say that the part needs to be place and will cost around $800 for one light. This is a common problem in all GM made vehicles and seems to be more noticeable in GMC Yukon. I have been told by several people my light was out then it pops back on and even the police has stop me for my tail light before. This is a safety issue that could cause warm to me and my family (two small toddler) which I Transport to and from school or someone else family due to alot of your customers mainly purchasing this vehicle to Transport their families from one place to another. It troubles me that we pay $60K - $70K for these vehicles and the only solution is to replace the light with the same faulty part. This issues happens when park and driving. I live in baton rouge, la and I use the interstate to get to and from work each and every day. I would like to see GMC provide a solution that fixes this issue and not profit off of a bad part but forcing it's customers to constantly have to replace bad tail lights. I love my GMC Yukon and will continue to purchase one as long as I feel I'm getting a quality vehicle for the amount of money I'm paying.
One of my led tail lights went out but it randomly comes back on, then off again. When I notified the dealership they mentioned this is occurring a lot on this model and age.
My air conditioner is out! in the middle of summer in Georgia! I had it diagnosed from someone I trust and from the dealer, both said its a crack which causes the refrigerant to leak and lose pressure. There has been exactly zero damage or any foreign object that caused this. We know it is a defective part that GM uses. Also, my rear passenger tail light is out and has to be replaced to the tune of about $600. This too is a common problem with these vehicles that is due to a defective part that GM uses. I have 2 friends with the same year model vehicle and they both have had this problem. Again, no outside influence such as damage or foreign object has caused this. I bought an extended warranty when I purchased the car. I called to have the repair for A/C covered but my warranty was out (had run out 600 miles before I called!) and 2 seperate representatives told me they have about 2-3 claims per week on this specific A/C problem with GM vehicles.
The brake lights work and then stop working. It is not the bulb nor the fuse. I was told it could be the light assemblies which is very costly. This has been going on for a few weeks. I have done research and it seems there are a lot of issues with the brake lights for this make and model of vehicle. Many people state they have the same issue.
Both drive side and passenger tail brake lights not working. Issue caused by the leds being a 1 large cheap circuit inside the unit. The circuit cracks causing the lights not to work.
