My vehicle is currently in the shop getting the motor worked on for a bad lifter. From the information the mechanic provided me this is a common issue with the vehicles that have the Active Fuel Management system. They are seeing many of these vehicles have to come in and have very expensive repairs. My first quote I received was $16, 000, they told me I needed a whole new motor and this assessment cost me $365 and a rental car while they looked at the truck. Now it is in the shop again and the estimate is $6000 to machine the cams as there are metal shavings in my oil. I had to again rent a rental vehicle and have not had my truck for a week. This is the third mechanic that has seen multiple of these motors have to be replaced or repaired due to this issue. I kept up on my oil changes and other recommended car maintenance and so did the owner before me. I had my last oil change approx. a week before the loud ticking noise began, then my vehicle began to have a noticeable loss of power when driving and eventually began shuttering and my check engine light began to blink and I took it to the shop. A year ago I had to replace my tail lights. I was able to find where others were recalled by my VIN for some reason was not included in the recall. They started shorting out and working only part of the time which is very dangerous when stopping, especially at night. I had them replaced and paid almost $700 for the two back lights.

Both tail lights fail. I just bought this vehicle at Ewald Automotive in Oconmowoc Wi a month ago with 100k and I know they were aware of the problem and so is GMC. I am not paying 900 bucks for each tail light. They are absolute junk. The left side someone already messed with it because there is electrical tape on it. Ewald laughed in my face.

The brake lights intermittently come on and off. Not reliable and the entire assembly has to be replaced per light in order to work. Sometimes if you hit a bump it will work for a bit then go back out. They have been removed, cleaned, but there is no way to fix them without replacing them. This is a known problem with GMC and they will not warranty or recall this issue.

The taillights started to randomly go in and out. The driver side taillight stopped working but the passenger side taillight still worked. Then a day later the driver side taillight worked, but the passenger side taillight didn’t work. The next day we were going to look into this issue, and the driver and passenger side taillights were working, so we halted. We kept an eye on it and they seemed to continue to work for a few days with no issues, so drove it 20 miles to work. When I left work it was dark and I had a coworker check my brake lights before leaving and the running lights and brake lights were indeed working. By the time I arrived at home, I had no running or brake lights. This is and was a danger to others and myself as this could’ve caused an accident driving and the taillights going out. The truck did not give a warning message that I had no taillights.

This is a common issue that is not being resolved by GM. First one, now BOTH of my rear tail lights are malfunctioning due to manufacturing defects. This is a well publicized problem and I feel that GM should be responsible for continuing to ignore the issue. Replacement tail lights are approximately $750 each. There are many businesses that have sprung up solely to repair these tail lights.

Tail lights are very inconsistent of working or not working. Sometimes they work but most times they don't.

NHTSA ODI 11527296

Both tail lights have stopped working. I purchased in 2019 with 60k miles and by the time the first tail light failed, I was over the 72k limit. If these lights failing was an issue before, it still is an issue and the special warranty should be extended to ensure replacement of faulty items.

Numerous reports of taillights and headlights not working properly and no recall like it should be

NHTSA ODI 11494821

There was recall for N182180270 Tail Lamps Inoperative, for some reason my vehicle being a 2015 was not included. This issue is ongoing with my 2015 Yukon Denali and is dangerous while operating, it recently started and is intermittent. Also my vehicle has issues with hard shifting and jerking intermittently when taking off.... also a known issue for this year and make/ model of vehicle

NHTSA ODI 11492590

Rear passenger running lights just stopped working. I have seen several people with the same issue. I think there should be a recall for GM to fix the issue they are clearly aware of.

NHTSA ODI 11492496

I received a letter from GMC dated December 2019 warning of brake lights intermittenly not illuminating. I have periodically checked the lights for failure over the last 3 years. On September 8, 2022, a motorist pulled beside me and informed me that my brake lights were not working. I confirmed that the lights were not working and called GMC regarding the letter I had received in 2019 and was told that a recall had not been issued and that my vehicle was outside the 6 year eligibility period. This defect is Extremely Dangerous to myself and others due to the inherent unpredicability and unreliabilty of an important safety necessity, i.e., knowing that others will see that I am stopping/slowing down. I believe that due to the intermittent nature of the failure of a highly necessary safety feature, GMC should issue a recall to repair at no cost ALL vehicles.

Tail light failure with no ability to change out bulb. Entire assembly must be changed which costs nearly $1000.

NHTSA ODI 11478524

My taillight has blown and I read online that several other vehicles like mines had this problem. The bulb itself can not be replaced. The whole LED box need to be replaced and one side onlybis roughly $800. Being a single mom of 3 boys, how can I afford that? I need my car inspected but with this issue I dnt know what to do. Please help.

NHTSA ODI 11478537

I have had to replace both front and rear exterior lighting in past (3). Now my rear brake light is now out. This makes 3 exterior that I’ve had to complete replace. Went out suddenly. No way to replace bulbs, dealer reports Entire assembly needs replacing at cost of almost $1000. There has to be a design flaw that every exterior lighting has gone out for so many owners and has to be REPLACED. There should be a recall on this. This model has had so many costly issues.

Brake lights - left brake light works intermittently, and often does not work. 3rd brake light (top center) has quit working. Both are issues with cracks in the circuit board, which googling has shown to be a known issue. Faulty, poorly designed or constructed parts!

NHTSA ODI 11448167

Both my tail lights have failed. Dealer wants insane amount of money for new ones, so I opened up the lights and there is an obvious design flaw in the lights, to me it seems intentional at worst, incompetent at best. I am an electrical engineer, and there is no reason they should put a friction connection in the LED power bar, it is a glaring design flaw. Also having steering assist issue at low speed which was an issue that was supposed to be fixed in a previous recall service, but it is still malfunctioning.

NHTSA ODI 11445923

Break like when out and only solution iam being given is to replace the whole housing at 800$ and it seems this a faulty component.
