Electrical System Problems of GMC Yukon - part 1

I’m not happy with just a change in oil viscosity because the car has already been on the road for 70000 miles before we were aware of the recall on the engine. Changing the oil viscosity doesn’t help when there is a underlying engine problem it should be replaced not just change your oil and send you on your way because now I’m always wondering and worried if the engine will still fail when my kids and wife are in the car. Furthermore I just had it inspected and the oil changed to new viscosity a week ago and the oil level is already half way on the dipstick so I’m taking back to the dealership to express my concern. If I would have known this was going to be an issue with this SUV I would have purchased something else. I’d just like the engine replaced so that I don’t have to worry every time I pull out of the driveway with my family. My power steering assist still whines and there is no open recall on it. I think GMC should be responsible for replacing engines and power steering assembly and power steering motors on 2021 GMC Yukon denalis because of the wear and tear they have endured before the recall was taken care of by adding a different viscosity oil because the damage has already been done.

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.

Electronics- module went out @40,000 brand new car drive train teal differential went out.

Driving through the intersection of n. Scottsdale road and e. Bell road in scottsdale az my collision warning red light flashed on the screen and the engine turned off. This caused me to lose forward propulsion and forced me to navigate to the side of the road to avoid being hit by another car. At van’s GMC, the service manager told me that we experienced a catastrophic engine failure and that the engine seized. Vehicle has been inspected, but I have not received an official diagnostic even though I have requested. There were no warnings or indications that the vehicle was compromised prior to the engine turning off.

The brake light is out and a single tail light is over 500$ very dangerous to have tail light out and can cause an accident. There should be a recall on these defective led lights.

My vehicle, with only 2,400 miles on the odometer, has been diagnosed as requiring a full engine replacement. While driving on the interstate, a warning message appeared indicating reduced acceleration. I was able to exit the freeway safely, but the vehicle could no longer maintain adequate speed to match traffic flow. Prior to this, the check engine light came on, but no issues were reported in the vehicle’s status system. I contacted onstar, and they advised me to take the vehicle to a dealership within seven business days. It has since been at the dealership awaiting parts. Upon further research, I discovered that this issue appears to be widespread. General motors has issued a technical bulletin addressing the problem, which involves complete engine replacement. Additionally, the audio system intermittently emits a loud crashing noise that is startling and potentially dangerous—it has caused me to veer off the road due to its intensity. This issue also seems to affect other 2025–2026 Yukon and tahoe models.

Purchased 2023 GMC Yukon on August 21, 2025 and after starting the vehicle on October 2, 2025 the whole instrument panel cluster malfunctioned, failed to turn on, currently does not work and is available for inspection upon request. The instrument panel cluster is all black, it shows glitching flashing white lines on the right side of it therefore being unable to read the speedometer, fuel gauges, tire pressure, oil life, engine temperature, etc. . Prior to the instrument panel cluster malfunction, there were no warning indicators. Being unable to view the instrument cluster, makes the vehicle hazardous & risky to utilize for me and my family. This vehicle has not been confirmed or inspected at this time.

Onstar module bad.

Keep quit working when I was driving , I just pick up from delearship for I another issue with on-star and is not part available is been there for over month not fix and now the brakes issue.

I attempted to start my vehicle and it turned over and at the end of trying it sounded like it wanted to start. This repeated itself with no change. I contacted the dealer which I purchased it from and the service mgr said it was the fuel pump control module. Numerous 2021 Yukon had this problem and there is both a service bulletin and a recall for this part. N212332040. My vehicle is not on recall. I attempted to have it towed to the local chevy dealer and was unable to as no local tow company had the tool to put the transmission in neutral. They all wanted to drag it onto the trailer. Bad design that it can not be put in park if it’s not running. I purchased a replacement fuel pump control module part 13554821 from the dealership. I installed it and the problem was fixed. I have the defective part if needed. This would have been much more of an issue if it happened anywhere other than my house, especially with the inability to put he transmission in neutral !!.

I'm reaching out because I've encountered a really concerning issue with my 2025 GMC Yukon at4 ultimate. There's a really loud popping noise randomly coming from the speakers that's honestly quite startling and dangerous while driving. Most recently, it scared me so much that I swerved off the road and nearly crashed. If you review online forums, you will find that this has been experienced by other owners as well. I've tried to resolve this through your usual service channels, but my concerns have been dismissed without any recommended action to ensure my family's safety. After scheduling with my local GMC dealership they couldn't replicate the noise and sent me on my way. I also brought it up with GMC customer care, and they suggested I try to record the sound, or keep bringing it in for service if it happens again. The problem is if I tell them it keeps happening again, what good will it do? it's a loud pop coming from the back speaker area. Even if they had 7 technicians hearing it at the same time, how will that make a difference. I need them to start testing components and replacing them one by one until its resolved.

I am the owner of a 2024 GMC Yukon (VIN: [xxx] ), purchased from hatchett Buick GMC on [xxx]. This vehicle was purchased at a high price with the expectation that it would provide reliability and keep my family safe. Unfortunately, that is clearly not happening. The Yukon continues to suffer from severe power loss that neither the dealership nor gm technicians have been able to diagnose or repair. In addition, this vehicle is subject to an unresolved engine recall, further undermining safety and confidence in the vehicle. Multiple times while driving I have had total power loss with no warning or indicators of this happening through lights or warnings on the vehicle. This is separate from the engine recall issues I am currently experiencing as well. While driving the Yukon will lose all electrical power. The vehicle is still currently at the dealership trying to be diagnosed. It has been 2 weeks. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

We brought my 2023 GMC Yukon into parks GMC in greenville SC on July 26, 2025 for the engine recall that we received a letter from. We left it as we were going on vacation for the week and picked it up the following Saturday August 2nd. The next week my engine light started lighting up and my husband contacted the dealership and we were asked to bring it back in. We did and were told that we now had a bad telematics communication interface control module that was causing my engine light to come on and that we were going to have to pay $600. 00 out of our pocket to have this repaired. After researching we found that this is a very common and widespread problem with a lot of owners right after they bring their vehicles in to be serviced. We declined the repair, one because they did not have the part in stock as that apparently is also a big problem of not being able to get the part in stock and two because we feel like we should not have to pay to have this part replaced as it appears to be a widespread issue that is happening. The dealership also charged me $182 for diagnostic charges that I once again feel like we should not have had ton pay. Please advise us ASAP. Our contact info is [xxx] [xxx] & [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have had problems with the navigation system where the screen goes blank. The radio is not responding and screen is black. When turning on the signal light you can't hear it. The speed limit in my town is 25 and after an update from the dealership it now says 55. I get an alert saying frontal crash not available atleast once a month. There are times when we are driving and we get the red alert as to detecting an object and there is nothing there. Parking assits does not work all the time.

My telecommunications module is no longer working for onstar, which means I can no longer call if something happened. The WI-fi is not working. The vehicle thing is on recall and now my check engine light is on.

The onboard accident emergency notification system has failed after 2 years. The sos and onstar are not functional. Car has no data communication with the network. Was confirmed by crenwelge motors in kerrville texas. It is a GMC dealer. This is an ongoing problem with many Yukons made from 2022 to 2024. Gm has not addressed the issue with a recall and does not have the parts to repair this safety system.

I was driving from new orleans with my family when traveling at 75 mph when it’s like the transmission started straining and the engine was losing power/pressure it’s like the engine or transmission was struggling I’m not sure what was causing it but it was a scary experience knowing I’d my kids and my wife with me and we were out in the middle of nowhere.

My vehicle’s engine failed for the second time while driving on the road. The first time a few months ago while my wife was driving. The engine failed and brakes failed. Fortunately she was on a back road a coasted to a stop. Car was towed to dealership. They said there was no problem. Received recall letter about a month ago outlining this issue. Yesterday, [xxx], I was driving with my daughter and the car stopped again while driving. I was in traffic and narrowly missed an accident. Gwinnett county police came to the scene and towed the vehicle to the dealership. I am not sure if the female officer made a report. But she requested the tow truck because I was blocking traffic. We often drive on the highway for work commutes. This could have happened and anyone in my family could have been fatally injured. I would like GMC purchase this vehicle back or replace with a safer model comparable or better. The service department called me this morning from jim ellis GMC in buford, georgia 678-902-8677, 3600 buford drive 30519. I was told that there is no recall for my truck. He told me that there is a safety investigation for a recall. I told him I can bring the letter. He decline. I asked for a courtesy vehicle. He said no, he would have to make a report and it would be up to 48 hours. Once it’s reviewed , then I could go to enterprise car rental to pick up a car. Maybe. The first time rick hendrick GMC duluth , GA 470-822-3779, 3344 commerce Ave, duluth, GA had my truck for about 2 weeks. No fix. No courtesy vehicle or rental. Now I’m without my vehicle for unlimited time. The jim elis tech, did acknowledge that there is no fix for what is going on. The local GMC dealers are not making this easy or putting the safety of its customers as a priority. These trucks are not safe on the road. This truck cost nearly $100,000 and it is not safe to drive. GMC has a record of the 1st service incident and this latest just happened yesterday.

Vehicle: 2021 GMC Yukon denali component: fuel system, gasoline – fuel pump control module incident date: 7-10-2025 mileage 61,263 location: sr 2006 coats, nc summary of complaint: while my wife was pulling out of our neighborhood in our 2021 Yukon denali, the vehicle suddenly shut off while navigating a slight curve. It came to a complete stop in the roadway and could not be restarted. The engine would not crank, and the vehicle could not be shifted into neutral, making it impossible to move out of traffic. The Yukon remained disabled in the roadway for over an hour and ultimately had to be towed. Upon inspection, the dealership mechanic immediately identified the issue without even running diagnostics. He confirmed it was a failed fuel pump control module, which he stated is a common issue with this model. This failure represents a serious safety risk, particularly had it occurred on a high-speed interstate or in dense traffic. A sudden loss of power and inability to move the vehicle can result in dangerous roadside situations or collisions. GMC needs to address this recurring defect before it leads to more severe incidents or injuries. No warning lights or indicators appeared prior to the failure.

Speed control became stuck and I had to hit my breaks to stop acceleration. Vehicle stopped shifting while driving down the road periodically. Warning collision lights and traction control lights randomly come on with nothing in front of vehicle. Yesterday vehicle would not start or even unlock. When I did get the vehicle to start by manually unlocking it and trying over and over it would not go forward or backward although the engine did rev up. All warning lights were on including traction control and check engine. It did randomly start moving but the “service steering column” light and check engine light are still on . The car periodically revs up while going down a hill when it needs to downshift instead. It has completely shut off driving down the road through town and stopped. I had to hurry and turn it back on as there were cars behind me. It’s a 2023 and I don’t feel safe driving it with my kids.

The on star module no longer working. This is a safety feature included in the manufacturing of the vehicle.

For whatever reason our 2021 GMC Yukon denali is not listed in the current 2025 GMC motor recall including cams and lifters and accompanying parts. While driving our truck about a mile from the house the vehicle began seizing and shaking (almost as if we had blown several tires); we immediately pulled over and accessed. Called dealership and had truck towed there immediately. We are told that it needs cams and lifters and that b/c our VIN does not pull up a recall that the repairs will cost ~$9800.

The driver-side headlight and turn signal on my 2022 GMC Yukon stopped functioning completely. This issue began before gm recall 22v?903 and worsened immediately after the recall repair was performed. The recall repair required three separate dealership visits because it was initially performed improperly, yet the problem was never fully resolved. During interactions with gm and the dealership, I was told the repair might involve a $600 part, but they could not guarantee that replacing it would fix the issue. It is unreasonable and unsafe for me to be expected to cover the cost of repairs for a problem that was caused or worsened by a recall repair performed incorrectly. The malfunction creates a serious safety hazard, as oncoming drivers cannot see my turn signals, and I nearly had an accident because of it. The problem has been confirmed by the dealership and documented in gm case #74327012. Prior to complete failure, the driver-side turn signal and daytime running lights occasionally stayed on after shutting off the vehicle which I was told that was caused by the recall. The vehicle has been inspected by authorized gm dealerships multiple times, but the defect persists. The component is available for inspection upon request.

I was driving on a highway with my [xxx] son and 2 dogs when without any warning the vehicle just stopped and completely went dead. I was unable to turn on the hazards so I called 911, the police came within minutes and surrounded the vehicle to keep us from being crashed into. The brakes failed to work, the hazard lights would not work, the doors would not open other than the driver door. The police had to help remove my child and 2 dogs from the vehicle through the driver door. The vehicle could not be put into neutral so the police had to tow the vehicle from the middle of the highway. The result could have been deadly. The vehicle was completely dead with absolutely no function. After the police towed it to the police tow facility it was then towed to the GMC dealership I purchased the vehicle from. The dealership is jim curly GMC in keyport NJ. The dealership has had the vehicle since Saturday and is claiming to not know what is wrong with the vehicle.

I am experiencing ongoing issues with the infotainment system in my vehicle, which has remained unresolved despite multiple service visits. The system frequently blacks out, reboots while driving, and fails to function entirely at times, for days at a time. This is more than an inconvenience — it presents several serious safety concerns, including: •loss of the rearview camera and parking assist features, making reversing hazardous. •inability to access hands-free calling and navigation, increasing the risk of driver distraction and noncompliance with hands-free driving laws. •disruption of access to climate controls and safety alerts that are routed through the infotainment system. •frequent system crashes while driving, which divert my attention from the road. These issues compromise both the safety and usability of the vehicle, and I am requesting immediate action to resolve the problem under warranty.

I’m filing this complaint regarding my 2022 GMC Yukon denali (VIN: [xxx] , msrp ~$76,805) with an unresolved l87 engine recall. I made an appointment at my local GMC dealership on 5/8/25 specifically for the l87 recall. Upon arrival, staff only documented the serial data gateway module recall, which I hadn’t even known about. When I mentioned the 6. 2l engine, I was asked if I was “sure. ” I believe I was treated dismissively because I’m a woman. After pushing back, staff pulled up the bulletin, confirmed my engine needed replacement, and told me to “drive it until it blows up or there’s a fix, whichever comes first. ” the l87 was only added to my receipt after I insisted—it was falsely listed as an “added operation,” though it was the reason I came in. I sent a certified letter to gm on 5/12/25 (signed for on 5/15/25) confirming the date I tendered the vehicle. Both gm and the dealer were fully aware the 60-day federal repair window had begun. It is now well past that deadline, and the l87 recall remains unresolved. Compounding the issue, the ac failed on [xxx], and the vehicle has been parked since early June due to extreme ky heat, making it unsafe to drive my children. I rely on this vehicle for daily commuting—driving ~100 miles/day for work—and it is also the only vehicle we own capable of towing our family boat, which has now sat unused all summer. I am currently paying $1,000/mo for the Yukon, $600/mo for the boat, and $200/mo for insurance—$1,800/month in preventable financial losses caused by gm’s failure to act. No repair has been offered. No loaner vehicle has been provided. No response has been received. I believe I was misled and discriminated against at the dealership, and I am now financially burdened and without a safe, reliable vehicle. This situation qualifies under the national traffic and motor vehicle safety act for repurchase, compensation, or forced resolution. I am requesting a formal investigation and full remedy.

The vehicle main information cluster randomly goes in and out and now has completely stopped working. This is the information display that shows park, nuetral, drive, reverse, fuel gauge, digital mph and other information such as oil tire pressure, turn signals, forward collision. Just knowing if the vehicle is in park reverse or drive is a huge saftey issue. This seems to be a common problem on gm vehicles and I wcan't seem to find a recall issued for the saftey factor that the vehicle can be assumed to be in park and it's actually in reverse. The first time I noticed this problem was sept. 05, 2020 but it had reset when I restarted the vehicle. The problem would resurface occasionally but always came back on when restarting the vehicle. But know it seems that restarting the vehicle is not fixing the problem and the screen has been blank for the last 3 days.

While driving at approximately 30 mph in moderate traffic on the interstate during a return leg of a 370-mile trip, my vehicle unexpectedly shifted into neutral and became unresponsive. The dashboard displayed the warning message: "condition not correct for shift," and despite repeated attempts to restart the engine, the vehicle would not engage. Although the electrical system remained active, I had no propulsion. Critically, the vehicle became immobilized in a **very dangerous curve on the interstate**, presenting an extreme safety risk to myself and others. The car could not be manually shifted into neutral for towing, prompting illinois department of transportation (idot) to declare the location unsafe. I was stranded there for over three hours, after dark, in a vulnerable and exposed position. During the forced tow process, two rear tires were destroyed and the two front tires sustained major damage. In the days leading up to this incident, the vehicle had also shown signs of malfunction, such as delayed acceleration from a stop and occasional lurching forward — symptoms consistent with the defect described in the recall.

Rear view camera fails to display on screen when vehicle is shifted to reverse. Failure remains during the remainder of ignition on cycle. The failures does not generate system error codes. Dealer service unable to diagnose failure.

Engine was replaced 11/24 found toe bar loose and rear passenger tire had excessive slack in it, well liners were broken off and missing 2/25 oil loss and had to have oil changed early 4/21 start button will not engage, truck is completely blacked out, no power to it for several minutes then it will crank. Been in the shop as of now 3 times in the month of may 2025.

Engine light keeps appearing and when checked it shows catalytic converter needs replaces and its sensors need replaced. Brake light has short in it and I repaireable.

I jumped in and turned the car on and started driving. Right away I noticed most of the warning lights were on. The first speed bump in the complex made me realize I had lost 80-90% of my brakes as if I had a broken brake line for example and steering was a little hard and pulling a bit to one side. I check underneath I did not have any leaks. I decided to take it to the dealer to have it checked. Dealer said they were not able to find anything and cleared the codes.
