Problems with 2015 GMC Yukon EXTERIOR LIGHTING

For the past 3 years i have taken my truck into the dealership with complaints about intermittent brake light function. specifically the lr light was not working. once i was told i had to replace the entire assembly $800 - i came in to have the repair done, then i was told there was no issue. i returned again when the police gave me a warning about the same light. was told no issue. several times i have been alerted by other drivers that the light was out - sometimes it works if i smacked the exterior of the assembly but not consistently. now - all of the brake lights are out lr/rr and the bar. i cannot drive it safely and i cannot believe that the only option is to pay several thousand dollars to replace it. many have the same complaints. this should be a recall! we already paid several thousand dollars to buy this truck - it should not have these issues so early on. i have seen many other yukon's on the road with the same issue. my car is 2015 - the problem started almost immediately for us after purchasing. this is not acceptable.

At 32,000 miles we had our back tail light go out. gmc replaced it at cost to them which was around $280 . less than 6 months later the other tail light went out and dealer told us 'lights go out'. we paid full price $680 to have it replaced. now our left tail light is out again and it'll be another $680 or more to be replaced. this is ridiculous. they are led tail lights. these she last a very long time. thousands of others are having this problem. car gurus has a blog solely about this. the odd thing is they are mostly 2015 yukon's. a recall needs to be done on this problem and the thousands of people dealing with this should be reimbursed for replacing these tail lights over and over! if you pay 60,000 for a car you should not go through this.

Tail lights work inconsistently, dealership tells me it's common problem with my year and model.

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.

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!

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.

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 yukons. 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 ...

2015 denali with 30k miles (still under manufact warranty) brake lights quit working. dealership stated tail light assemblies needed to be replaced.

Stop light dont work

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.

Driver side break light works intermittently. after researching multiple owners in similar model years have noted the issue being inside of the light itself having an electrical issue. but the dealership wants $750 for a new one when the problem is wide spread, needs to be recalled and made right.

My brake lights on my 2015 yukon dinali went out on the right side. i was informed by the dealership that they are not responsible for this and none of my warranties will cover it.

Rear passenger tail light out and passenger window only goes half way down.

Rear brake light assembly failing to light when brakes applied and there is not a notification to the driver. this is a manufacture flaw with the led light circuit inside the assembly. there is not a light out notification so the driver is not aware the brake light has failed. this is a safety issue and is an well known issue on the 2015-2019 yukon. this is occurring often and gmc is having problems with supplying replacements because the demand is so high from the failure. gmc has also raised the price of the brake light by 30% from $425 to $675 not including labor. i called the dealer and they informed it was a high failing item and was on backorder and not sure when they would get one. driving the vehicle without proper brake lights is a safety concern and not legal so left with little option but to stop driving the yukon.
