Electrical System Problems of GMC Yukon - part 2

The digital gauge cluster suddenly black out and do not show any information such as speed, rpm, signal, etc at all. This is very serious issue for driver and passenger safety.

The car started to have issues shifting when driving- automatic transmission. It would jolt or shudder to try to shift. I was at a light intersection attempting to turn left to go on the on ramp of a highway, it attempted to shift as I sped up from a stop and it got stuck and started making a sound as if you were to press the brake and gas at the same time, similar to that, a car was coming in my direction at the same time and it finally clicked into gear. Absolutely terrified me, my father in law came and switched me vehicles and took mine to the dealership where it stayed for 3 days and they diagnosed it saying it needed a new transmission, quoting us at $11,000. Obviously we can’t afford that. We had all the filters and lines of the transmission cleaned. And now it’s just gotten worse and worse. That was the first time it happened. Now it’ll shudder like that any time it’s switching gears at any speed. Another time since then, it got stuck in the same situation after pulling out of my kids school driveway, it got stuck and wouldn’t click, when it finally did it started shaking uncontrollably in the street and thankfully I live two streets over and made it to my street before it just shut off on its own. I coasted it right into the front of our house and then it would not come back on, at this time we searched the internet over and over to find try to find an easy fix. We let it sit before it came back on. This is our family vehicle. I’ve seen that many many people have this exact issue with this exact same year and model. Its not coincidental and it’s extremely unsafe. Especially with kids in these vehicles. I’m terrified one day when it gets stuck or shuts off we will get hit.

While driving 75 on the highway the vehicle shut off completely, shifted to neutral and a message flashed on the dashboard to "press start again". This has happened previously when my 16 y/o was driving but we chalked it up to user error. Scheduled appointment with dealership. There were no warning lamps, no lights illuminated on the dashboard. The vehicle just cut off and I have not been able to reproduce the issue.

A side detection module pin was corroded and was disrupting the electrical signals to major vehicle components, such as the dash (dic). The dic would lose communication with the rest of the vehicle while driving so no vehicle operation data was visible such as speed, alerts messages, etc. This likely also caused engine failure due to the incorrect operation of the afm which is on the same electrical circuit. No warning messages were given. The bad side detection module was diagnosed and fixed at a dealer and shortly after engine issues were noticed.

The engine system (6. 2l v8 l87) in my 2022 GMC Yukon xl failed due to a known manufacturer defect tied to NHTSA campaign 25v-274. The vehicle is available for inspection upon request. The issue involves the risk of sudden loss of propulsion, which could result in a crash or injury to myself or others. This is a serious safety concern, and I do not feel safe operating the vehicle in its current condition. The defect has been acknowledged by GMC, but there is no remedy or repair currently available. I have contacted the selling dealership (rick hendrick Buick GMC, duluth, GA) repeatedly for the past three weeks with no returned calls. I also contacted GMC corporate, who confirmed the recall but refused a buyback or replacement because no repair has occurred — even though a fix does not exist. They offered a loyalty voucher that does not come close to addressing the safety risk or impact. The problem has not yet been inspected by a dealer or manufacturer because there is no repair action to take at this time. No police, insurance, or third-party has reviewed the vehicle. There were no warning lights or messages prior to the issue — the problem was revealed when I looked up the VIN and learned of the active recall on the engine. I am requesting NHTSA’s support to ensure general motors provides a replacement vehicle and compensation for this ongoing and unresolved safety hazard. I should not be placed in a position where I am expected to continue operating a vehicle with a known and dangerous defect that has no resolution in place.

Today while exiting an off ramp. I stopped for traffic signal. Truck immediately lost power and shifted to neutral. I placed my 4 ways 1. Put the people back in park restarted the ignition truck fired up. This is concerning as I've never had a vehicle with five thousand miles brand new shut off on me.

The wireless charging pad in the vehicle below the climate control system. Yes, it is. The charging component malfunctioned and overheated the back of my phone when it was set in the console while driving. I had no intention of charging my phone, but instead place my phone down while driving. When I picked up my phone at a stop light, I laid it in my inner thigh when the light changed. The burning was so intense and unexpected I swerved into oncoming traffic and lost control, momentarily of the vehicle. I have recreated the incident in a controlled environment myself and the issue is still active. I am happy to have the issue confirmed independently. I gave notice to the dealership after it happened with no concern or further investigation. No, the vehicle has not. No, no warning at all. In fact this is my 3rd GMC Yukon since 2016 and all 3 have had the wireless charging pad, I have had the same phone as my last one. I never had an issue or experienced anything like this.

Vehicle went to gm for recall repairs on 02/24/25 the morning after when I cranked my car it was dead. Jumped the car off then began hearing a "clicking noise" gm advised I replace my serpentine belt as they noticed it needed replacement when doing the recall repairs. 02/26/25 serpentine belt was replaced but car still seemed to have power issues when cranking. 02/27/25 car barely cranked then while driving down the highway I lost all power and power steering to the vehicle. There was no warning, no check engine lights etc. The screen went black then car shut off then the screen said "press start to restart. " I was barely able to get the vehicle safely off the road with vehicles in front, behind, and in the other lanes. It could have caused a fatal accident. GMC still has my vehicle with no update on replacement engine timeline.

We were driving down the interstate at around 70mph and without warning - the vehicle shut off. The engine stopped running and the vehicle put itself in neutral. The headlights and electrical all shut off and the only message on the display was to push start to restart the vehicle. Luckily, we were able to safely maneuverer out of traffic without being hit by other vehicles. Our vehicle was able to be restarted once we came to a complete stop and put the car in park. We are having he vehicle towed to our local GMC dealer to have it evaluated. The issue only happened one time.

The engine of my 2024 GMC Yukon denali failed unexpectedly at 45 mph, shutting off without warning and shifting into neutral. My wife, three passengers, and two dogs were in the vehicle, which coasted to a stop. After several attempts, it restarted, and the check engine light illuminated. Alpine Buick GMC confirmed catastrophic engine failure, requiring replacement of the engine, radiator, hoses, and other parts. The vehicle remains at the dealership, and the failed components are available for inspection. This sudden shutdown posed serious safety concerns. My wife lost control over acceleration and power steering, increasing the risk of an accident. Had this occurred on a highway or in traffic, the consequences could have been severe. This raises concerns about the engine’s reliability and potential risks to other drivers. Alpine Buick GMC confirmed the engine failure and the need for full replacement. I am the sixth customer awaiting this repair, indicating a broader issue. The estimated wait time for an engine is two weeks to three months, creating a significant disruption. Inspection by manufacturer, police, or insurance the vehicle has been inspected by dealership technicians but not by GMC representatives, police, or insurance adjusters. I am open to further inspections to determine the cause and assess whether a recall or corrective action is necessary. No warning lights or symptoms appeared before the engine shut down. The check engine light illuminated only after restarting on the third attempt. The absence of prior alerts suggests a flaw in the vehicle’s diagnostic system. Expedited engine replacement – given the safety risks, I request priority replacement. Investigation into failure cause – GMC should assess whether this is a manufacturing defect. Review of similar cases – if widespread, a recall or service bulletin may be necessary. Better communication – regular updates on repairs and GMC’s actions are needed. I expect prompt action to resolve.

Engine failure (engine seizure) (connecting rod bearing failure). Enige failed on an interstate highway causing us to nearly be struck by traffic moving at a high rate of speed. Also, engine failed on an extremely cold (-17) degree minnesota night. This cause extreme concern/anxiety with children in the car as we waited for recovery. Yes, the problem has been confirmed by a GMC dealership in hudson WI. Yes, the vehicle component has been inspected by both GMC certified technicians as well as 3rd party warranty technicians. Zero warning lamps or messages prior to the failure.

The digital instrument cluster blacks out randomly at times going down the highway. This is a safety concern because you can't see how fast you are going. The problem has been inspected by and confirmed by a dealer service center. The failure began without warning and seemed to occur after the car went through a gm software update. The service manager for the GMC dealership said this is likely a bug that gm will have to solve through future updates. The car's electronic system was reset but the problem persists.

I purchased my new GMC Yukon xl in October 2024. In February, with about 9,000 miles on it, I was approaching a highway intersection and beginning to brake. My vehicle put itself into neutral, and then shut off -- while I was still moving. No dash lights came on, except for a message stating that I needed to press the brake and restart my vehicle. I took my vehicle into the dealership where I purchased it and they kept it for 8 days. They were unable to reproduce the issue and didn't do anything to mitigate the problem except for doing a "radio update" and adding lubricant to a window track. I was told I have to wait until it happens again and try to record it.

While driving the 370 miles from fairbanks to anchorage with our family and dogs, our vehicle shut down completely with no warning. The drive is through a very remote section of alaska. While passing a slower vehicle, our Yukon completely shut down, to include the all controls including the dash and lights. We were unable to complete the pass, leaving us in direct line with on coming traffic with no ability to speed up to get around the other vehicle. The other vehicle, not knowing we had lost all power, continued driving the same speed and eventually we were able to get back into the proper lane and coast to a stop on the side of the 2 lane highway. The vehicle would not start and with the temperatures outside at 12 degrees it got chilly fast. Luckily we travel with all of our winter gear. Had this incident happened on one of the many steep descents or curves with snow and ice, the outcome could have been disastrous. My wife has decided that if the vehicle does get fixed, she does not feel safe driving home in it. Reading online forums show that this is a very common occurrence and individuals are looking into a class action lawsuit against gm due to the safety issues associated with this. An individual passing by had a code reader and tried to reset the ecm but could not. I will include the report.

What component or system failed or malfunctioned, and is it available for inspection upon request? the engine suffered a catastrophic failure, including a bottom-end bearing failure, causing the camshaft to seize, the flywheel to shear off, and metal to spread throughout the engine, cooling system, and radiator. This also tripped the main fuse, resulting in an electrical short. The failed engine is currently at the dealership and is available for inspection upon request. How was your safety or the safety of others put at risk? I was driving on a 55 mph highway when the engine completely shut off without warning. Losing all power while traveling at highway speeds was extremely dangerous, and I was barely able to glide the vehicle to the side of the road before it lost momentum. It is terrifying to think of what could have happened had I not been able to get out of the travel lane in time, especially with other vehicles moving at high speeds around me. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, the dealership diagnosed the issue and confirmed the engine failure. They have determined that a full engine replacement is necessary. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? the vehicle has been inspected by an authorized GMC dealership service center. I have not yet had it inspected by any other parties. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? no warning lights or messages appeared before the engine shut off. The failure was completely sudden and unexpected, with no prior symptoms or indications of an issue.

I constantly get the frontal crash not available warning the navigation picks up on conversations stereo freezes navigation screen has been blank no map data visible screen will not change from daylight to nightime anymore (I have taken the vehicle twice to the dealership and have it repaired then it happens again) when driving the vehicle will randomly brake and says something is near when there is nothing close.

While driving on the highway the engine just shut off with no warning or other indication of problem. The dashboard computer instructed to restart the vehicle, which it would not restart. Managed to get to the side of the road. But the vehicle was unresponsive. After about an hour the lights in the rear of the vehicle flickered, so I attempted to re-start -which it did, and was able to drive the vehicle to the dealer (about 20 miles away). Where the car remains today. The incident occurred Feb 2. Took the dealer until 2/6 to advise me that the engine would need to be replaced. At that time they indicated they would need to car for about 2 weeks. I contacted them on 3/3 and they informed me they had no idea when they might be able to get the parts to replace the engine - there was a 3,000 engine backlog? clearly there is a major issues with these engines; how are they allowed to continue to sell these vehicles, and allow current owners to operate them without a notice? while I was fortunately able to get to the side of the road - have in the car lose power suddenly lose power is clearly a safety issue!.

We were driving uphill on the highway, about 60 mph when the engine appeared to loose some power for about 10 seconds even though the engine was reving higher, and the ln the engine cut out. We coasted to a stop and then the electrical system was cutting out. I tried to restart the engine but it would not turn over at all, and the car’s electrical was intermittent. There was no warning or error lights before or during the engine failure. Photos provided are the messages on the instrument cluster when attempting to restart the engine. Vehicle was towed to the local GMC dealership, and they are replacing the engine under warranty. No eta on the engine replacement at this time.

Engine failure at 19k 14months old 6. 2l 2023 GMC Yukon denali ultimate "everyone is having an issue these engines coming apart" low milage.

The 2023 GMC Yukon had a complete loss of power and engine while driving 65 mph on a highway. The vehicle was unable to restart or be placed into neutral. No previous issues and no indications of failures. No fault codes or lights indicating any issues. Dealership informed me that the engine stopped working and gave an estimate of greater than 4 months for any replacement or repair.

Good afternoon. Our rental car we picked up from the denver International airport on [xxx] had numerous incidents of emergent braking at highway and non highway speeds which were reported to sixt ( car rental) and documented on the dates in which they occurred, [xxx] (7-8 occurrences ) and [xxx] (3 occurrences-2 after a car wash). On the day in which the first occurrences happened, the car rental company representative from sixt, 3way connected me with a mechanic from annex who advised washing the vehicle to ensure the sensors were clean. I did proceed to wash the vehicle on 1. 25. 25. This same company, annex automotive, then evaluated the vehicle on 1. 29. 25 after emergency breaking occurrences continued of which [xxx] was the worst. On [xxx] there were no vehicles in front of or behind us nor to the sides of us and the roads were completely clear. It was also dark out. Attached you will find evaluation with validation there is a mechanical concern with the vehicle. On [xxx] the extremely unsafe occurrence of emergent braking occurred with skidding tires and the doors locking and unlocking at the same time occurred. This vehicle was completely unsafe to drive. I, as well as my passengers/family, are very lucky the road conditions were moderate on [xxx] and clear on [xxx], or these emergency breaking issues could have caused a serious accident. There were a total of five of us in the vehicle when all of these occurred. I am from minnesota and have a Yukon xl so I am comfortable with this vehicle this was the scariest vehicle experience I have ever encountered. The company did tow the vehicle on 1. 29. 25.

2024 GMC Yukon with less than 2,000 miles decided not to start one day. Had a tow truck come to the house and pick it up to take to a local shop to get a new battery. Replaced the battery and the battery shop delivered to car back to our house and was totally fine…the next day we went to start it and again the battery was toast. So, got another tow truck to deliver to the dealership and had it checked out, the dealership says there are 12 codes popping up and they can’t figure out why the batteries are not holding at this point. This is a diesel Yukon. We had a 2022 escalade that the motor went belly up on us 3 times before we bought this diesel Yukon thinking this problem would go away but I guess I was wrong. I will be returning this Yukon to the dealership and doing a buyback. We have been stranded way too many times with these gm vehicles and I’m starting to loose trust with general motors.

I have had this vehicle serviced twice for the electrical issue on the running boards. While driving and while parked the running boards constantly deploy and store on their own or get stuck at a half way position. This will happen even if I have them turned off or on.

Traveling north bound on highway 14 in southern California on January 24, 2025. In the fast lane traveling approximately 70mph when with no warning what so ever the vehicle shifted into neutral and lost power. Nearly rear ended trying to get out of traffic and to the right shoulder. Once stopped the vehicle would not start, stuck in park, and could not turn the electronics off. Stuck in vehicle for 3 hours because it was too dangerous to exit vehicle. Tow truck arrived. Tried to jump the battery which by this time was dead. Had to drag the vehicle up the flatbed with wench do to vehicle unable to shift out of park.

While accelerating up to 55mph, the vehicle automatically shifted into neutral without warning. We tried to shift it back into drive, nothing happened. We pulled off the road to try and shift in a reduced speed and still nothing. We finally came to a stop and tried to shift it into drive, still nothing. There was an error message: “conditions not correct for shift”. We place vehicle into park, turned off the engine and tried to restart. The engine wouldn’t turn over. A police officer stopped and tried to jump the battery, nothing. The dashboard and lights turn on, but there was zero turn over with the ignition. We continued to try it to no avail. We had a tow company come and unplug the battery to try a system reset, and still nothing. Car was towed with no ability to get it into neutral.

At 9,900 miles my safety camera system failed which disabled the cruise control and all safety features that used the camera. Car was out of service for nearly two weeks and subsequently fixed by the dealer under warranty at no charge. At 11,300 miles I was driving on an interstate highway in the left lane at rush hour, without warning the car stopped accelerating the car shifted into neutral and totally lost power. It was a very dangerous situation with me in the left lane in heavy traffic. I am a skillful driver and thankfully I was able to make it off the travel lanes on the highway. The temperature was 18 degrees at the time and I had to wait outside for a tow truck. The engine seized without warning or noise and this presents a severe danger to the driver of the vehicle and other vehicles on the highway. There was a substantial possibility that other vehicles could not avoid me as I was exiting the travel lanes. There was also a substantial possibility that the vehicle would simply be in the travel lane stopped on a divided highway.

Roughly one to two times per day, a notification pops up on the infotainment screen stating that the brakes need to be serviced due to the brake assist system failing. The vehicle has been brought to 3 different dealerships and none of them know what the problem is, how to fix it, or whether it is safe to drive the vehicle still. The brakes seem to be working fine, however, it is concerning that even if the notification is safe to ignore, the brakes could indeed end up failing and the driver may not be aware due to receiving frequent brake failure notifications per day.

In July of 2023, my wife and kids were driving to san diego from phoenix. About 40 miles west of el centro, CA, all the lights on the dash came on instructing her to pull over. When she pulled over and shut the car off, it would not come back on. Got towed back to a gm dealership in el centro. The diagnosed it with a bad radiator and failed engine. The replaced both(at roughly 30,000 miles). The car was fine for about six months and then it started getting battery drains again, which continually happened starting a few months after purchasing the vehicle. They never could figure this part out. Anyway, early January of 2025, while driving back to phoenix from san diego, the car did the same thing. This time, it restarted and she could continue on her way home. On [xxx], while driving in town, the same thing happened, all lights came on, pulled over and car would not restart. It is diagnosed with the same issue. It has been in the shop at van GMC since January 12th, 2025 waiting on a new engine, at 63,000 miles. This will be the 3rd engine in the vehicle. By looking online, this appears to be a common issue and happens more than it should. This needs to be addressed. My wife has our kids in this vehicle a majority of the time and this is a major safety issue. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Complete failure of infotainment system in cold weather. This is a safety concern because most controls are operated through the infotainment system and can DE distracting to a driver who is trying to operate all features of a vehicle while driving. For instance having cold children in the rear seats and not knowing if the heat is activated in the rear of the vehicle and at what temperature or if it is blowing at all. There is no manual indication of rear climate. This is already a safety bulletin for 2021 Yukon that for some reason my vehicle is not included in. Gm recall number: n212327470 I want my vehicle included since this is a safety concern ( see above ) and this should be a real recall rather than a notification or safety bulletin.

Onstar module doesn’t work it went out in January 2025 there’s a 1000’s of other users in the in the onstar module community complaining of the same issues . When you take it to the dealership they will not assist and will not warranty it out.

Since purchasing the vehicle in September with 8 miles there have been several electrical malfunctions. Some “fix” themselves when I restart the vehicle and several have needed to go into service. The first issue was when my mirrors wouldn’t come back up when switching to drive. I disabled the reverse tilt option and had it serviced to be fixed. Apparently it needed an update. More recently I had several malfunctions. My vehicle would lower its self while still in gear, and it wasn’t the normal self leveling. I didn’t not have any warning lights or messages pop up. The next time I started my vehicle and had “service rear axle” warning. I called the local dealership and after restarting the vehicle several times and more error messages, I decided to attempt to drive the vehicle in, all the while recovering several message warnings. On the way I was increasingly loosing brakes and I rolled into their parking lot with no breaks. Since this episode I have had repeated lost connection codes without dash warnings. They first attempted to reprogram the brake control monitor. Then when it continued to lower itself and have other malfunctions it went back into service. They replaced the serial data gateway and reprogrammed it. Since then the vehicle is having lost communication codes every day. It is currently in service to try and figure out what’s causing it and hopefully fix it.
