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.
2017 GMC Yukon XL engine complaints
Page 2 of 2: complaints 11 to 26 of 26, newest first, as owners wrote them.
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 '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.
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 .
When accelerating the car starts bucking, after driving some more shakes like going over speed bumps.

Car struggled to start when I started it. Idle was/has been really shaky. Engine light came on. I got a diagnosis from 2 companies for my engine. Both said I needed to replace all 8 fuel injectors. Gmc has an extended warranty to cover these issues, but it is not available for my state of utah. Here is the code for reference for yukon #n182198000. My car is a yukon xl 2017 that needed fuel injectors at 85,000 miles! How is this okay? The repair cost $1,990.28. The power train warranty has been changed for 2016 and 2017 gmc vehicles so that it is now 60,000 miles or 5 years. Mechanics have reported that gm has changed the way they are building engines in order to reduce costs, but it appears that consumers such as myself are bearing the brunt of the costs. I would appreciate if the extended service warranty could be extended to all states in the u.s. Vs. Those who have mandated it because of legislation or legal enforcement.
My vehicle transmission went out motor mounds went out and seat stopped working at condensor went out. And a few other things. Suv is a 2017 we have already spent over 11,000 in 2 years fixing it now the AC is 2400 to get fixed.
At 91k miles my transmission went out completely. The vehicle was less than 3 years old at time of incident
Brake failure after recall was done brakes still fail was driving and was braking the pedal went in all the way and the yukon xl denali did not stop also have bad fuel injectors took it to the dealership and they dont know what fuel injectors go on the SUV also gm doesnt know they have to take apart the engine to find out what fuel injectors they put on the engine they wont give me a car rental and does not all the fuel injectors are on back order there is 3. Types high pressure low pressure and they dont know the fuel injector that was used I paid over 90,000 with taxes and interest on this 2017 yukon xl denali and they have replaced 3 shocks, brake vacuum pump, brake and rotors they had to repaint the feont bumper rear bumper hood and back door and now the fuel injectors with only 37,500 miles this SUV is a junk and now I believe all gm cars are now junk
Air conditioning quit working - clearly an issue as described in lawsuits and on-line search reports, not covered by manufacturer
This vehicle breaks failed on me while driving a very known issue on previous year
While parked and running with no driver in the vehicle, the vehicles key fob was locked in the car by a passenger exiting the vehicle. The passenger, a child, exited the vehicle and pushed the "door lock" button and then closed the door, locking it while running with the key fob in the vehicle. No warning alert noise was emitted and the vehicle did not automatically unlock the doors as designed. The weather was approx. 80 degrees. This hazard is not suppose to occur and poses a high risk of causing harm or death to an unsuspecting passenger. The hazard mitigation for this event failed.
While driving, the check engine light intermittently flashes. Vehicle runs extremely rough, sluggish at times. Dealer checked vehicle over a period of time and eventually confirmed random misfires. Unable to fix issue. Unable to determine cause. Vehicle was later confirmed to have a faulty transmission transmission replaced by dealer.
