2017 GMC YUKON XL Complaints

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!

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.

There was a pump in the heart of the transmission. The dealer said told me that was leaking fluid. Apparently this was a faulty hose within the transmission which leaked fluid in the transmission. Therefore, my transmission died. This was a severe I could have been a very dangerous situation if my kids had been in the car. I’ve had to pay almost $8000 for the transmission to be fixed and yeah I see that on the line there was some sort of recall but my dealership is saying there was not. I bought this car brand new and I’ve had it for seven years. I’ve never had an issue with the transmission on any of my vehicles ever.

Truck RPMs were running really high between shifting with normal acceleration. I took the truck to a transmission shop as I purchased an extended warranty. The transmission needed to be rebuilt as many parts were worn. The extended warranty repair was made. After repairs, the truck has started doing the same thing 4 weeks later. It appears the transmission is not properly shifting again, I am not sure if it's a transmission issue as all parts have been replaced, or a computer issue that's causing the malfunction. The vehicle is available for inspection. My safety is put as risk because if the transmission does not shift properly, it is at risk at breaking while in motion which could potentially cause an accident and if the transmission breaks will on the highway, i dont know what type of risk that can entail. The transmission shop has indicated that they are noticing the same issue as before and do not see any reason for the issue to be continuing. There were no warning lamps or indicators that have shown up to indicate an issue. This is noticed by daily driving of the vehicle and noticing normal and not normal RPMs, shifting points and feeling.

Car has 100k miles on it. At 59k the fuel injectors went out and needed to be replaced. Then the transmission went out and needed to be replaced, then the front differential needed to be rebuilt, also had to replace the struts. Now the lifters are going out and that, plus likely the camshaft, need to be fixed. Total costs for all the above is close to $20,000. If not fixed these problems could easily result in catastrophic engine failure while driving leading to personal injury and death. I see that there is a class action lawsuit for the latter.

The rear lift gate on the Yukon xl has the automatic sensor underneath the trailer hitch that you can swing your foot under to open or close. Twice, while loading groceries, I have had it close on my head, and this time with concussion symptoms. This also happened to my elderly mother.

The 'active fuel management/displacement on demand' lifters failed and caused the engine to run very poorly with a significant lack of power. This occurred while driving and could have caused a crash before I was able to get off the road and out of the way of traffic. The problem was diagnosed and confirmed by an independent repair shop. The vehicle had to have the camshaft and all valve lifters replaced, as well as several valves that were damaged in the failure. The total cost to repair was just over $9000. The failure also caused the catalytic converters to become clogged, resulting in even further loss of power from the engine. There were no warning lamps or symptoms prior to the failure. It occurred suddenly as I was driving down the road. Searching online reveals this seems to be a common problem with GM 5.3 and 6.2l engines from 2010 onward. GM is aware of the issues and refuses to assist in any way. Their only response is that the vehicle is "Out of warranty". The failure is caused by a design defect in the AFM/DOD system that starves the lifters of oil, resulting in lifter failure and damage to the camshaft and valves.

Consistent with NHTSA Special Coverage Adjustment 17336, the A/C condenser began leaking in my 2017 GMC Yukon XL. I am filing this complaint for NHTSA to consider extending the mileage limit for the special adjustment. Unfortunately, this occurred at approximately 80,000 miles, or 8,000 miles after the special coverage adjustment. It may have, in fact, occurred sooner than 80,000 miles. I noticed the problem at the end of May 2023, having not engaged the air conditioning unit since on or about October 15, 2022. During that time, I probably put 8,000 miles on the vehicle. The problem was confirmed by Wilkins Automotive in Glen Burnie, MD. They provided an estimate of $2,600 for parts and labor to fix the problem. When I contacted GM and mentioned the special coverage adjustment, they offered me "400 or 500" GM points, or the equivalent of a few oil changes. I ultimately had it repaired at a reputable independent repair shop for $1,050. FYI, the GM dealer quoted more than $600 for the freon. While freon is expensive item, the independent repair shop charged me just over $300.

I have a 2017 Yukon XL with 80,000 miles on it. Last year I was driving on the highway with my kids when it began to lose power and failed to accelerate. The issue was in the engine and I had to replace the entire engine for $8000 because it was barely past the warranty. Now one year later the car began to jerk and not shift while on highway and it is the transmission that is going to be replaced for $6000. The 2017 Yukon XL is a lemon and very dangerous for drivers. I spent $45k and should not be replacing the engine and transmission withing 6 years of it's age. Reading online these are common issues putting lives at risk.

Driving towards the bank and suddenly the truck turned off … no warning nothing it turned off while operating .
