1 Exterior Lighting problem

Failure Date: 11/12/2025

At stop light vehicle began to sputter and make noise, I was very close to my home, no engine light on. Upon turning vehicle off and using a code reader codes p0106 and p0506 was on scanner. I had vehicle towed to complete car care. Mis fire on multiple cylinders. Vehicle has 69,801 miles. 3 push rods bent and I valve spring broken. The right cylinder head assembly had to be removed and replaced with 8 new push rods, 8 new lifters, gaskets, seals, and valve spring. Cost was $3304. 79. In addition the rear tail light has been sporadic on and off, gm was to replace up to 70,000 miles. When I took it to them they stated the time limit had expired, yet I had not been informed until I did a google search. Gm requesting $475 plus tax. I am concerned my vehicle has the same manufacturing defects as the gm motors being recalled with total engine failures.

Failure Date: 11/12/2025

At stop light vehicle began to sputter, run rough, and make noise. I was less than a mile from my home, no check engine light on. I turned the vehicle off, used a scanner to have codes p0106 and p0506 show. I had vehicle towed to complete car care. Misfire on multiple cylinders, 3 push rods bent, one valve spring broken. The right cylinder head assembly had to be removed and replaced with 8 new push rods, 8 new lifters, gaskets, seals, and valve spring. Total cost $3304. 79, the vehicle only has 69,801 miles on it. In addition one of the rear tail lights has a known issue (found out on google), intermittently goes out, was never notified. I took the car to jim hudson GMC to be told it would cost $475 plus tax because I did not come in early enough even though it is to be warranted up to 70,000 miles. I am greatly concerned that this engine has the same manufacturing defects of the current recall and extended recall for the GMC Yukon denali engines.

3 Exterior Lighting problem

Failure Date: 07/16/2025

We noticed the passenger side taillight was out. It’s not a simple bulb replacement but an entire assembly. It was put back in place and it lit up again. A few weeks later it wasn’t working. Pounded and tapped on it and it works again. We're guessing there is some sort of short so we asked for an estimate on getting an assembly replacement when it was in for a regular oil change. Shocked that a necessary part would cost $1,112. 77!!! whatever happened to changing a bulb for a few dollars?.

4 Exterior Lighting problem

Failure Date: 05/29/2025

I was stopped at a traffic light and was informed by another driver that my right tail lamp was not working. There were no warning lights indicating that there was a problem. When I arrived home, it began working after I tapped on it. A few days later, the left tail lamp stopped working. I began to realize that both tail lamps were only working intermittently. Upon inspection by the mechanic, I was informed that this is a common problem with my vehicle and that each replacement part is approximately $900, totaling nearly $2,000 to replace both lamps. This is an obvious safety hazard for myself and for others who may not be able to judge when I am stopping, especially if I have to stop suddenly.

5 Exterior Lighting problem

Failure Date: 06/05/2024

Drivers side tail light flickering and sometimes not working a $900+ cost! I issue with right hand side when SUV has 32k miles, seems like this is an ongoing issue, luckily it was still under warranty the 1st time. The ac condenser when out in April, also an know issue with the Yukon, they wanted to charge me $1500 to repair, I was able to find someone to do it for around $600, now the outlet and usb ports seem to not work. I also had an issue with the braking system , dealer couldn't figure it out, I finally found someone to repair it, $500 fix. For what I paid for the Yukon, you would think they would use top of the line parts!.

6 Exterior Lighting problem

Failure Date: 03/12/2024

Rear led taillights circuit boards broken. Disabling both stop tail lights causing serious safety hazard. We had no clue driving around and we didn't have any brake lights another driver had to tell us. So we googled this problem and it turns out that all of 2017 GMC Yukon have the same issue. There's even multiple websites to repair them as well as auto supply stores selling replacements for $1,000 and the dealership wants $1,500. This is a real problem and gm needs to make this right and recall all of these and replace them before somebody gets hurt if they haven't already.

7 Exterior Lighting problem

Failure Date: 02/22/2024

In July 2021 the passenger side tail light stopped working. A certified GMC dealer replaced both tail lights. In Feb 2024 the driver side tail light failed.

8 Exterior Lighting problem

Failure Date: 01/25/2024

Rear (tail/stop) lights on both sides, would work intermittently. Turns out it’s a known issue with the led circuit boards. They consistently break in 2 places, leaving the vehicle with no tail lights/stip lights. Gm knows of the issue , but since it’s not considered a safety issue, they do nothing. It’s clearly a safety issue, as following drivers may not see lights, on the rear. Clearly, it is definitely a safety issue, as it can easily cause an accident, not knowing a car is there in the dark , or not knowing that the vehicle in front of them is on the brakes, and slowing.

The contact owns a 2017 GMC Yukon. The contact stated that on several occasions while the vehicle was parked, the passenger’s side rear taillight failed to illuminate. The vehicle was taken to an independent mechanic where it was determined that the full assembly light kit needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the issue. The failure mileage was approximately 80,000.

10 Exterior Lighting problem

Failure Date: 07/19/2023

Rear brake lights fail due to an issue known by GMC - multiple GMC Yukon and Yukon xl have this issue. All within the same year. The metal connector in the brake housing fails and requires it to be soldered or a complete replacement costing consumers $800+ for replacement. A severe safety issue as the brake lights quit working!!.

16 Exterior Lighting problem

Failure Date: 05/11/2023

One rear brake light was intermittently malfunctioning even though the vehicle only has 80,000 miles and is a 2017 model. Upon researching online, I saw that 2015 and 2016 models were recalled for this. 2017 was given a limited term to have the vehicle fixed if they were experiencing the issue. I was not experiencing the issue at the time, so I was responsible for a large chunk of the cost of repairing the light through the dealer at GMC. GMC did inspect the vehicle. The company was made aware of the problem. The dealer discussed it with them and they agreed to pay half as a "favor" basically to have the rear light replaced.

23 Exterior Lighting problem

Failure Date: 06/27/2022

Driver’s side rear tail light stopped working. It’s not even 5 years old. Bought August 2017 brand new. I know there is a recall on 2015-2016 models for the same problem.

24 Exterior Lighting problem

Failure Date: 05/14/2022

Passenger brake light stop working. Had the dealer ship inspect the light and was informed that the whole unit had to be replaced at a cost of $1000. So I purchased the part for $800. And replaced it myself tech. Informed me that gm had a recall on the 2015 and 2016 model's but has not included the 2017 model year.

29 Exterior Lighting problem

Failure Date: 03/13/2022

Just driving along yesterday in my Yukon, and when I stopped another driver pulled up to me and informed me my right rear brake light is not working. Upon further investigation, it comes in and out (sometimes it works sometimes it does not). I had this same issue with my 2015 Yukon, I would have thought gm would have this fixed by now, very expensive fix on my 2015, assuming it’s the same cost or close. Very dangerous to have a brake light out and reduce another drivers reaction time to stop and prevent a rear end collision. Furthermore the vehicle has no indication that a light or bulb is out, a lot of vehicles have that programming, surprisingly this does not.

30 Exterior Lighting problem

Failure Date: 03/02/2022

Taillights and brake light leds go out unexpectedly or work intermittently creating a safety hazard that drivers behind the Yukon are unable to see your taillights at night or when your braking causing potential rear end collisions. For this common problem gm recalled the taillights of 2015-16 models, but the 2017+ models that still have the same exact taillights with the same issue but has not been recalled yet. Costing owners out of warranty $800 per taillight assembly. Please look into this safety issue.

31 Exterior Lighting problem

Failure Date: 03/01/2022

The left rear tail light has gone out. There is no user replaceable bulb and this is a sealed unit. The deal has quoted almost $800 to replace. I feel a sealed unit should not fail prematurely and should last the entirety of the life of the vehicle. Had it been user serviceable, this would be a simple repair/fix.

32 Exterior Lighting problem

Failure Date: 02/21/2022

Brake light on the passenger side has failed and non operational. I have researched this and found it is way to common to not be a manufacturer design issue.

33 Exterior Lighting problem

The contact owns a 2017 GMC Yukon. The contact stated that while using the remote start-up feature, he noticed that the rear passenger's side brake light and taillight were inoperable. The vehicle was taken to the dealer and diagnosed that the taillight assemblies needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 41,169.

34 Exterior Lighting problem

Failure Date: 12/24/2021

Rear led brake light stopped working. Supposed to have a vehicle lifetime lifespan. I. E. Never require replacing. This light assembly was found to be defective in the previous year model and not fixed.

35 Exterior Lighting problem

Failure Date: 11/25/2021

Taillights and brake lights inoperative. GMC knows of problem and refuses to repair vehicle outside of manufacturer warranty (lights failed after warranty period). I have seen several other Yukons on the road with no brake lights or tail lights. Extremely dangerous situation.
