Equipment Problems of GMC Yukon - part 1

Driving out a town 400 miles away, with a young passenger in my car on hwy 459 in rush hour traffic, I started hearing a slight ticking sound then moved into a full blown knock on my drivers side ( I recorded it). Within minutes, my oil light came on and my dash notification reading "engine overheating idle" with the knocking really load. I had to cross 3 lanes to traffic quickly to get to the shoulder of the road, which was not a safe place. I smelled smoke and cut the the engine off. I popped the hood to see that there was now no coolant (that is all I knew to look for). I immediately called onstar roadside assistance. 2 hours later, I was towed to a local hotel room. Car completely dead. Not lights, couldn't lock it, nothing. I had to pay a large fee (almost $2k) to have my car towed back to nc from al not to mention having rent a rental car to get us home. The car is now at a GMC dealership in monroe nc. Of course the powertrain extended warranty doesn't cover the battery replacement, belt replacement and water pump replacement so now I'm out of pocket $1300 just to get those install to be able to try and start the engine to further diagnose if my I have complete engine failure and without transportation.

The rear view camera is not sufficient for full time use. The camera is positioned too low and during times of dawn/night/dusk if a truck of similar size pulls up behind you, your camera is completely blinded by headlights. Leaving you unable to see anything in the rear view camera. This is a serious safety concern as you are unable to see if anyone is approaching your vehicle to cause you harm. The low camera placement also does not allow for an acceptable/comparable view as using the rear view mirror. The zoom does not pull out far enough to see multiple lanes of traffic and even during the daylight, if someone is approaching the vehicle to cause you harm, it would not be visible. The camera placement only allows you to view the front grill or hood of the vehicle behind you.

While engaged, super cruise failed to detect lines on road on a bend and launched the vehicle in the opposite lane without warning. This has occurred two separate times. First time was in late June 2025 on the PA turnpike. Traveling at 70 mph. It was a left hand bend in the road where it failed to detect lines on road and thrust vehicle into the right hand lane. Happened so fast there was no time to react. In addition lane keep assist was active as well. Also note lines were present on the left and right side of vehicle. Luckily no one was beside me. Second time was one a two lane road going 45 mph. Same scenario as first. Vehicle dic stated it had lost road lines and threw me into the left lane without warning. Luckily no car was coming or it would have been a head on collision. Same message o display vehicle lost lines on road.

My vehicle went from driving perfectly to startling and not going pass 45 in a matter of two days. I was getting all maintenance done at dealer always on time had just service it. When all of a sudden it started making a jerking/ skipping feel as if I was accelerating too hard. Took it to get checked and the code that came up was (tcc)torque converter clutch. I spent 6000 to rebuild the transmission and kno the engine has a tap tap noise. Once again I took it in and now it’s the lifters in the engine. No warning light have ever popped up.

A recall notice was issued in April 2025. I have tried to get the recall issue fixed but my dealership has stated they cannot touch it yet as parts are not available. I have been told to continue driving my car and use only the oil as stated on the oil cap. My tab renewal notice has the recall listed, my GMC app shows the recall and NHTSA shows the recall. I have not been told when I can get my potentially faulty engine fixed or even looked at.

The dashboard cracked.

While super cruise was engaged the car changed lanes automatically without any action on my part. The problem is I had set the automatic lane change feature to only activate when the turn signal was switched. While examining the vehicle settings I discovered that the feature was set to automatic not turn signal activated. What cause the software to change this setting? the service tech could not find any problem but guessed that when the software is updated it goes to a default setting. This is wrong. Setting should not change. The setting also changed on opening the tail gate with my foot. This setting was turned off.

10 speed transmission it’s been at the dealer for a month and they checked it today. Same issues as the mass recall dash alert for reduced speed drive with caution. It was extremely dangerous because it malfunctioned on curvy winding roads.

The GMC is starting to loss power in the engine. GMC has not send me an appointment to inspect the engine. This vehicle is my only transportation to work and doctors appointment. This is not fair for a powerful company like GMC is not taking the ownership of the engine in this vehicle. I need action ASAP. Please assist. Thank you.

I had a sudden catastrophic engine failure 3/13/25. I previously filled out an NHTSA report, but I would like to add to my case. My engine was towed to the dealership and replaced. 4/25/25 the check engine light started coming on intermittently again. The service suspension notification, replace the battery in your key fob notification (which was replaced in February), and the check engine light have been coming on intermittently since then. All of these things occurred prior to engine failure the first time. The dealership would not look at our vehicle again until our VIN was called for the recall. 6/22/25 the suspension sensor was replaced and the recall “test” was done. 6/27/25 the service suspension light was back flashing and gm was unable to find any codes. 6/29/25 the check engine light was flashing again. I believe my vehicle is going to have another engine failure. Gm did a multi-point “inspection” and says it is safe to drive.

The air conditioning system in my vehicle failed in April 2025. My dealership service department diagnosed the problem as a refrigerant leak requiring the compressor to be replaced. I had the $2400 repair made replacing both the compressor, condenser and the a/c system was charged. 2 months later, I am having the same issue again - failure of the a/c system due to a refrigerant leak requiring the condenser to be replaced. A quick google search identifies a recall on the 2019 Yukon xl noting a "refrigerant leak due to thermal cycling". Though this is the precise year, make, model and distinct problem that I am experiencing, my specific VIN has not been included on the recall. We are in the height of summer, currently experiencing temperature that feel like 104-107 degrees in east tennessee thus is has become a safety issue for myself, 4 children and husband to travel in our primary/only family vehicle. I find it unbelievable that a vehicle of this caliber has a basic (air conditioning) system failure after 6 years; however, it is incomprehensible to spend $2400, have it repaired, know there is a recall for the precise vehicle and concern, have it fail again and be expected to spend another $2400 because my specific VIN is not included. It is simply preposterous. I am requesting that my specific VIN be included on this recall, please.

GMC unable to remedy a recall that appears to be dangerous to operate without being addressed. Recall number n25249000.

The sunroof exploded while driving down the highway.

I am filing a complaint regarding a potential safety defect in my 2024 GMC Yukon denali (approx. 25,000 miles), which has been in the dealership’s service department for about 30 days due to a faulty valve body in the transmission system. There is currently no estimated date for repair completion due to a lack of available parts. This is the second time the vehicle has been in the shop for the same unresolved issue. Earlier in 2025, I brought the car in due to driveability concerns and error messages appearing on the dash, but the dealership dismissed it and claimed I had “turned the vehicle on wrong,” despite it having a push-button start. The problem persisted until June 2025, when they finally diagnosed the valve body failure. This issue directly affects drivability and vehicle safety, particularly during acceleration and gear shifting. I am concerned that general motors is aware of widespread valve body and transmission failures in these vehicles, yet continues to produce and sell new units while failing to ensure parts are available to support timely repairs. It is unacceptable that a major safety-related transmission issue can sideline a relatively new vehicle for over a month with no resolution in sight. Gm’s lack of urgency in addressing this defect suggests a disregard for consumer safety and reliability. I respectfully request that the NHTSA investigate this issue as a potential pattern of safety defects in gm’s full-size SUV transmission systems.

Problems with the engine shifting gears stalling delayed or won’t engage hard shifting while it’s in motion something’s going on with the engine we’ve called several and had it serviced times of times to ask them what was going on with it in newport oregon you can fill it still when you drive. The problem still is not fixed. It’s been happening since we purchased it took it in right away. We’ve asked if our VIN number has come up for a recall repairs we are worried for safety and are currently parking in the car because the dealership is unable to fix what is wrong with the car. They’re telling us there is something wrong and are aware of the recall and won’t fix the problem dealership refuses to take the car they don’t want it without the recall fixed due to safety concerns. You can definitely fill it when you drive I’m not exactly sure what the other issue if with the sounds it’s making when the issue keeps happening but it’s scary there is the recall on it. They are not taking into consideration or the seriousness of the situation and the safety of lives.

Sunroof exploded.

I was driving on the highway going about 50 mph and the engine just stopped. It was very dangerous, and I couldn't get to a completely safe spot. I was stuck for 45 minutes there until police could get to my Yukon and help provide safety. I had 2 other passengers in the car. All of us were put at great risk and the surrounding traffic was also at risk. The triple a towing took over an hour to get the vehicle on a flatbed because they couldn't get the Yukon in neutral. There were absolutely no warning lights or any weird noises, the car shifted out of drive and would not go back into any gear. I am waiting for the dealership to decide what to do. My main reason for writing this complaint is this is a big hazard, not only for people who drive/ride in these vehicles but for every vehicle on the roads around them. When they stop with no warning, accidents and I'm sure some with fatalities will happen. This is a critical situation, and these vehicles should all be off the road. My Yukon was in my dealership service for an oil change about 1 week prior to this incident and I had a long conversation about the recall. They said my Yukon looked great and nothing was needed unless I had any problems. Since there have been so many others with the failed engine, all vehicles with this recall should be off the road to prevent totally innocent people from being in these dangerous situations. This is preventable if these cars are forbidden on the roads!!! gm must take responsibility before lives are lost due to this negligent reaction of issuing a recall but saying it is safe to keep driving unless there is a problem. If the first sign of a problem is failure with resulting catastrophic outcomes, then just issuing a recall is not enough. This must be addressed, please. This was a terrifying experience for me and my riders. I have no idea if the police filed the report but they spent alot of time trying to keep everything safe due to this issue.

There is a safety recall but it has not yet been resolved, risking lives.

I own a 2023 GMC Yukon denali xl (VIN: [xxx] ) currently under active recall for the l87 6. 2l engine. Gm has no remedy available and has acknowledged a risk of complete engine failure and loss of propulsion, which could occur without warning. This is the primary vehicle I have for transporting my family of seven, including a toddler. I am significantly upside down on the loan, and the dealership cannot guarantee it is safe to drive. I am requesting that NHTSA escalate the urgency and hold the manufacturer accountable for timely resolution or replacement. ” information redacted pursuant to the freedom of information act (foia), 5 u.

On 05. 29. 25 my 2021 GMC Yukon denali with 24,000 experienced engine issues and ultimately a total failure. While driving at 65 miles an hour the engine light began blinking and a thumping/knocking noise began on the front passenger side of the vehicle. I was 1 mile away from the gm dealership and went there immediately. They called me two hours later confirming the engine failure and that it would have to be replaced. They stated, however, the engine is experiencing a national backorder. No timeline has been provided for the engine to be received or replaced. I am curious to know if the new engine will come from the same engine group that is currently having issues, and if this can happen again.

I purchased a 2015 GMC Yukon in March 2024 I drive the vehicle 9 mons, 7500 miles the vehicle has been in service at my local dealership since Dec 13, 2024, for engine and transmission replacement, I have had the vehicle back 3 weeks not the warning light and service warning chime for the "service trailer brake system is on, I have not ever use a trailer with the vehicle, I was told the vehicle needs a wire harness, I have read this a problem in these vehicles that has not been addressed GMC with a recall, I have put a lot of money in the vehicle. This is an well documented failure in the trailer brake system that gm should repair at no cost to the consumer.

I own a 2023 GMC Yukon denali with the 6. 2l v8 engine. A safety recall was recently issued for this vehicle due to a potential engine defect that could result in sudden and severe failure. However, gm has not provided a remedy, and dealerships are unable to offer any repair or trade-in options while the recall remains open and unresolved. I live in a rural area with limited cell service and long distances between towns. This makes the potential for sudden engine failure even more dangerous. Out of serious concern for my family’s safety, I no longer feel comfortable allowing my wife or our [xxx] child to ride in or use the vehicle. The risk of being stranded—or worse, getting into an accident due to engine failure—is too great given our location and the nature of this defect. I attempted to trade in the vehicle at a GMC dealership to get into a safer and unaffected vehicle, but the dealer refused to accept it because of the recall. This leaves me stuck with a vehicle that has a known safety issue and no solution in sight, limiting both my transportation options and peace of mind. There were no warning lights or prior symptoms before the recall. The issue was disclosed by the manufacturer. A dealer has confirmed the recall is active, but no fix exists. This situation is unacceptable and has real-world safety and financial consequences for families like mine. I urge the NHTSA to hold gm accountable and ensure a remedy is made available immediately to protect consumers who are left in limbo by this unresolved and serious safety defect.
