Owner reports

Selected complaints filed with NHTSA by 2016 GMC Yukon XL owners, lightly cleaned up (personal details are redacted by NHTSA).

Driving a company vehicle [redacted], heavy smoke started coming from under the drivers side dash. Unhooked battery, the smoke stopped. I had vehicle towed to a local garage. They advised the engine wiring harness and other wiring had caught on fire. They couldn't repair it. On [redacted]. I had the vehicle towed to the local GMC dealer in Bedford, VA. At first they said they could fix it, then around 7/3/24 they said the couldn't fix it, charging several hundreds of dollars. On July 5/2024 I had the vehicle towed to a GMC dealership in Lynchburg, VA who I had check with and said they could fix it. The first part of September 2024, this dealership advised me the couldn't fix the vehicle. I had the vehicle tow to our companies office in Lynchburg. The dealerships are saying they can't get the needed wiring harnesses. Our insurance company had sent an adjuster to the GMC in Bedford, VA. …

While driving down the freeway, I received a warning that the charging system was not working and had a red battery light come on on the dash. I exited the freeway trying to get to a safe place, the dash and infotainment system begun to flash on and off. We heard a loud pop, smelt something burning, saw smoke coming into the cabin and then flames from under the hood near where the battery is located.

Loses power randomly. More prominent at low speeds and turns. Has lost power going down the road, will turn back on. Stabilitrak lights and jerking steering wheel are more common. Will not always start right back up when it shuts all the way off/loses power. Loses clock but keeps radio stations. Had it scanned. Asked dealer about issues/recalls and information with nothing more than "this is not common" and "we need to schedule a time for you to bring it in". Times were not soon and they made it seem like it is not an urgent/emergent situation. Would not agree to me being able to talk with a tech. Looked into this as it seems common but nothing definite. Bad battery cables seem prominent, grounding issues, electronic steering module, and a few others. Seems like a GM problem that is known but not being handled. Greatly disappointed after reading up on it. …

There is a special policy to replace faulty tail lamps. However, the policy is only extended through 72,000 miles or 5 years which is ridiculous, and should be a recall. I had my drivers side tail lamp replaced in February 2022 because it was not working. I wasn't aware of the mileage and year restrictions at that time. Fast forward to today, I have my passenger side tail lamp intermittently working. Now out of the specific time frame, I'm left to encounter this expense out of my own pocket. Clearly GM is aware of the problem, but has not issued a recall on the tail lamp issue. It's not just a burned out brake light, but apparently an electrical issue with the way they were initially wired. This is a very dangerous situation, as I have no idea if and when my brake light is out. God forbid if they were to go out and I were to be rear ended due to GMs lack of taking responsibility.

While driving vehicle the vehicle appears to shut off as if someone is turning off the ignition. The steering control becomes stiff, power is lost and electronics flash and turn off and on. This has happened on multiple occasions and is intermittent during acceleration. The accessible grounds have been checked, battery checked and replaced, and alternator checked and verified to be charging appropriately. Several codes are present and have been cleared to return indicating low voltage issues with multiple systems.

I purchased a used 2016 Yukon xl may 20 2024. Over the last month only put 2k miles on it. I continue to receive a message to service trailer brake system. I dismiss this and it continues to chime and be a nuisance popping up blocking my dash from seeing important things like speed etc and the noise is extremely distracting as a driver. I'm unable to use the hands free talking through Bluetooth as it interrupts quite frequently. This makes driving an extremely dangerous and unpleasant ride

LED tail light unit continues to crack (metal inside) and not work. Each replacement is over $500. You have to replace or you'll be ticketed because it is a safety hazard. It is not a bulb replacement it is a faulty design that is costing people thousands to fix and it's not right. GMC is aware of this defect and they aren't doing anything about it. Please help and recall these taillights to be replaced by the updated lights!! Thank you for your time and consideration.

Like many other complaints..when your driving and accelerating it jerks and try's to change gears ect. Most recent issue is the temperature sensor went out and my fan was running on full speed. Well I got it fixed and within 2 months it has gone out again! Lastly, the paint on the hood and roof. When I bought the dealership fixed the hood and yet again it's failing again..

Both brake lamp assemblies are non-op, no warning in dash and no fuses. GMC #SCA N182180270 stating that 2015 and 2016 Yukon. Extended warranty to 6 years or 72,000 miles. We are out of warranty as of last month. $2,500 to replace the tail lamp assemblies. No letter was sent to owners regarding this safety hazard. This should be a RECALL

The driver's side brake light assembly failure of no brake light when brake is applied. It can be inspected upon request. This may cause another driver to not notice intentions to stop or slowdown and cause an accident. This problem is constant. It has not been inspected. No warnings of the failure has been displayed.
