Vehicle Speed Control Problems of GMC Yukon - part 1

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.

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.

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.

Driving down the interstate and engine gave out, started shaking, and started losing speed. No warning, in the middle of the night with two young kids in the car. Sat on the side of the highway in the pitch dark. 2 days later truck was towed but the GMC had no one to look at it. Had it towed again and that GMC dealership said it was the engine and they see it all the time with that year/make/model. $16,000 for new engine. Contacted GMC and they stated that year is not included in the recall. Research this issue on google and most owners of the same year/make/model have the same issue with no help to solve the problem.

Driving at 55mph and suddenly the car starts to shack and warning/notification lights copme up on the dash. Check engine traction control service light suspension service was able to drive it to GMC dealership nearby 2. 6mile.

There currently is a serious recall on this vehicle and there is no remedy available. I’ve called the dealership and they confirmed this information. The service department claimed the sales department may be able to help me and then sales said it was a service dept issue. I have children who have been placed at risk as they have been traveling in this vehicle since April 2024.

I am writing to express my concern regarding a serious issue with my 2021 GMC Yukon. Recently, while driving, I experienced a sudden surge in power. About five minutes later, when attempting to shift into reverse, the vehicle would not respond. I tried multiple times with no success. Afterward, while driving it briefly around the block, it made a clunking sound, which raised further concern. Ultimately, I had to call a tow truck, and the vehicle was taken to george gee GMC in liberty lake, washington. Unfortunately, the next day the dealership was unable to duplicate the issue. There were no warning messages on the screen at the time of the incident, and no diagnostic codes were found, so they could not move forward with any repair. I later discovered that this exact issue is addressed in technical service bulletin n242454441-02. However, I was informed that my VIN is not included in the special coverage, despite my vehicle being the same year and equipped with the same transmission mentioned in the bulletin. I am deeply concerned that this problem could happen again—possibly while I am driving in canada, transporting my children, or in a location where calling a tow truck would be very difficult. My safety and my family’s safety are at risk, and frankly, I am now anxious about driving a vehicle I used to trust. I also have an extended warranty, but when I contacted gm service, I was told that unless the problem can be duplicated, it would not be covered. This is extremely frustrating given the severity of the issue and the fact that it is already documented in an official bulletin. I am requesting that this situation be escalated. I would appreciate any additional support, coverage, or guidance gm can offer to help ensure this issue is resolved and does not put me or my family at risk again.

The car has made a high pitched metallic rattle on cold start ever since I received it. I have taken it into the dealership multiple times for this and have had the lifters in the engine replaced but they never addressed the other noise, which I have video evidence of. The car died at 24,740 miles on the odometer in the middle of a highway in the middle of nowhere. The vehicle started to feel like it was braking on acceleration, there were no warning lights. The vehicle just lost acceleration power and I had to coast to the shoulder. Luckily I had time to pull over without interference from other traffic. Once on the side of the road I tried to crank the car again and a very loud metallic sound happened that sounded like I threw a wrench in a fan. The car lost electrical power very shortly after. I called onstar for help and she asked if I could shift the car into neutral which I could not. They had problems finding anyone that wasn’t hours out that could come tow my car and suggested that I try to find an alternate method of transportation since a wrecker service probably wouldn’t transport my entire family. Uber was not around to get me, lyft was not around to get me and there was no taxi service. I had to rely on the local fire department to rescue us as it was hours with myself, my two children and my dog on the side of the road in 90f heat. Once at the dealership they confirmed it was indeed a catastrophic engine failure and I am currently waiting months for a back ordered engine with a rental I’m paying partially out of pocket for, in a car that’s entirely way too small for my family with no eta on the engine in sight. I know multiple people personally who this has also happened to, same exact scenario and same exact engine just different model years.

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.

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.

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.

Recurring system problems: my vehicle continues to exhibit intermittent system failures, causing unpredictable and potentially dangerous driving conditions. These issues have included: engine stalling, braking issues, electronic system malfunctions].

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.

The contact owns a 2024 GMC Yukon. The contact stated that while a friend was driving at highway speeds, the vehicle suddenly experienced a loss of automotive power and stalled. The vehicle was towed to the local dealer who diagnosed that the engine had failed and needed to be replaced. No further information was available. Additionally, the vehicle had previously experienced a loss of braking while driving with the cruise control activated. The contact stated that while driving at a slower speed the vehicle lurched forward, striking a gate, and causing damage to the front pumper of the vehicle. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure. The contact was informed of the NHTSA action number: pe25001 (engine, engine and engine cooling). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 16,000.

[xxx] while driving on [xxx] myself and my family in our 2022 Yukon 6 lane highway 65 mph the engine lost power with no warning at all and left us with no power steering ,or brakes. This was in heavy traffic with other vehicles on our right and left side. I was able to put 4 way on and carefully move to the right lane and then barely to the burm. Vehicle would not restart and the sound of it was of rattle and groan. Yukon was towed to the nearest dealer and we were told it was a bad engine of either bearings or rods. We were very lucky to not having an accident and harm my family or other persons on the highway. When a new engine was installed it ran for ony 15 minutes and also was defective for the same issue. Vehicle was returned to us on 12/14/24 and we were denied any additional warranty. At this point I have no confidence in the vehicle or general motors. We took a financial loss when we traded the vehicle because of the major problems thru no fault of ours. The dealer would offer nothing as far as extending the warranty nor would GMC customer service that we filed a formal complaint # [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

There are several incidents reported regarding ongoing assessment with GMC interplay activity I have noticed this have become a dangerous drive ability inside acceleration controls governor sets whiling driving engine play transmission shifts this have gone beyond everyday practices during drive times this have been very noticeable during anyone time rpm gauges constantly disrupted radio functions remote controls are at play many problems are being serious illegal assessed during drive compulsive fuel guagement. I have been placed at dangerous risk by interplay noticability. Now slight tick sounds after full services sparkplug and wire as tuneup oil changes fuel services and coolant same recurring problems continued after serviced alignment services. Controls are very strong.

Driving in my newer gm Yukon ultimate at 13k miles on the freeway. Vehicle with no warning shuts down while going 60mph in the middle lane. Was able to safely steer the car to the side of the road to avoid a collision. Vehicle lost all electrical contact. Could not shift into neutral to tow. Turns out vehicle engine had to be replaced. Gm approved a new engine replacement and are planning to return the vehicle back to put on the road. The vehicle is unsafe, at 5k miles, 6 months prior, the vehicle had to have the steering system replaced due to failure as well. Online research shows that others are having the same issue with failed engines on these gm vehicles and models.

Numerous difficulties have arisen during the process of driving on multiple occasions. The tablet/radio continues to reset, and the traction control sensor light continues to illuminate. I have communicated with the GMC service center on several occasions, and each time, no issues were found. During an oil change at another dealership, no service recommendations were mentioned, yet a list of offset services was listed on mopar. As I continued to drive, I noticed that the speed controls were limiting speeds, necessitating self-serviced accelerated drives. This has been ongoing for some time while driving and has required ongoing fuel adjustments. I have received tune-up services, coolant services, fuel services, wheel balancing, and several alignments, which have recently caused significant inconvenience. Routine maintenance has been performed, and the rpm gauge remains constant during operation. Make a unsafe drive.

Driving at 70 mph, the vehicle shifted into neutral without warning. When attempting to place the vehicle back into drive, the vehicle dashboard siad "vehicle condition not met" . I slowed the car and pulled over. It shifted into park but now will not start and will not go into neutral for towing.

Stabilitrak warning light comes on intermittently. Cruise or anti-lock brakes do not work when this condition is present.

My vehicle stalled while driving on a busy highway & I had no option but to pull over, which left me & my family in a very dangerous position. Had to remove my daughter's wheelchair onto a tow truck as the vehicle had no power to use the hoist for her powerchair. Again, on the side of a busy road! towed the vehicle to a gm dealership, who stated there was catastrophic engine failure & the engine had to be replaced. Had no way to transport my daughter until I got a new engine since her hoist was stuck at the dealership.

The vehicle was crawling to a stop in preparation to park in front of my garage door. When I move my hand across the steering wheel, my hand must have come in contact with the toggle/scroll for the “resume speed” function of the cruise control. The vehicle abruptly began accelerating towards my house. I was able to press the brake pedal to deactivate and stop the vehicle safely. I note that in the past week, perhaps even two, the cruise control has not been used. The vehicle is driven 2-4 trips a day.

No warning light presented to warn of transmission issues. While driving is hesitating sluggish when accelerating and stalling around 60mph then shifts . Putt putt then pick up a bit then back down.

My vehicle stalled while driving on a busy highway & I had no option but to pull over, which left me & my family in a very dangerous position. Had to remove my daughter's wheelchair onto a tow truck as the vehicle had no power to use the hoist for her powerchair. Again, on the side of a busy road! towed the vehicle to a gm dealership, who stated there was catastrophic engine failure & the engine had to be replaced. Had no way to transport my daughter until I got a new engine since her hoist was stuck at the dealership. This was our original vehicle, until the sold me another one with the same defect (2024 Yukon for more money!). That vehicle was reported in complaint 11657786.

While driving the vehicle it randomly looses engine function decreasing speed rapidly. The check engine light comes on and it says engine power reduced along with traction-off and stabilitrak- off. There was a safety recall 14v-614 that pertains to the chassis electronic module. I have had multiple shops look at the problem the last being a GMC dealer who replaced the accelerator pedal for the 2nd time but did not fix the issue. This issue began in early 2024 and vehicle has sat in driveway not being driven every since.

When driving in a parking lot, due to the design of the cruise control set switch, it is very easy to unintentionally set the adaptive cruise control. Specifically, when maneuvering in a parking lot at low speeds (below 5mph) and allowing the wheel to return to center by spinning in your hands, the cruise control switch which is a dial/lever that sticks out beyond the surface of the wheel, catches on your hand and engages the cruise. This sets the cruise control target speed to a 15 mph even if you are currently going slower than that. The vehicle then accelerates on its own at a fairly aggressive pace to get up to 15mph. You can of course hit the brakes and cancel the cruise control, but in a tight parking lot scenario this unintended acceleration could easily cause you to strike another vehicle, obstacle, or pedestrian. The cruise control on this vehicle is enabled by default on start up and the single action of hitting the set switch/dial engages the cruise and accelerates sharply even if you had not previously used cruise in that ignition cycle. This seems like a stupid design and dangerous, and would be very easy to fix with a software update to not let the cruise become enabled below 15mph. We did not have the dealer investigate because this appears to be the normal operation of the cruise control system. There were no unusual warning lamps. This has happened several times and also has happened to my wife while driving.

While driving, the vehicle display screen and lights start turning off and on. The warning lamp says " service trailer brake system" and the vehicle is unable to accelerate at all. Leaving me at a stand still in the middle of the road. It's a safely hazard because it happens suddenly and without warning and I am unable to move my vehicle so I'm just in the middle of the road. I haven't taken it in to the dealership yet. I looked online and there is a recall called " chassis electronic control module internal contamination" that meets the description of what's going on here, but when I called GMC they said there is no recall for my specific VIN, even though the recall is for my make model and year.

While driving my check engine light came on indicating that service was needed on the electronic stability control (esc), traction control, anti-lock brake system (abs), brake assist the vehicle top speed reduced to 43mph. My braking system was compromised and I have to travel at reduced speeds on busy roadways to arrive at my destinations. I have taken the vehicle to a certified GMC technician for diagnostics and repair.

It is just like the the service bulletin out for the 2006 and later GMC sierra except it’s for a 2004 GMC Yukon slt 4x4 4. 8l. It is going into reduced engine power mode and it has to do with the throttle actuator control module. Throws code p2108.

On March 10, 2023 I exit hwy 35 at the city of cottula texas, as I took the exit lane and arrived at the stop sign, the vehicle came to a complete stop the engine stop idling and the transmission switch to neutral, this created a safety issue for me and my family because I was unable to restart vehicle and I created traffic congestion at the intersection, I am worried that this can happen again and I might be exposed to other vehicles crashing against my vehicle or even worse if this is to happen in the highway I will not be able to control the proper handling of my vehicle.

Dash is cracked scared that sharp objects may fly into my family face if air bags are deployed the truck lost all power and left me and my daughter stranded right in the middle of traffic about got hit thank god we didn't gm needs to take care of these matters and take it seriously people could be seriously hurt or killed and if I hit a bump my cruise control will shut off automatically as if I pushed the button but I never touched anything.

Thr lifters shut down the engine and caused it to completely turn off the vehicle while in motion. It is available for inspection. Has not been confirmed by dealer. The code read cylinder 1 misfire but the lifters were not functional. The seizure of the engine and full stop of the vehicle while in motion nearly caused a 3 car pile up and a close collision into a fire hydrant as the steering locked and emergency brakes were not functional. There was no other warning lamps or messages offered prior to the shut down.
