The vehicle developed a recurring cylinder #4 misfire with a flashing check-engine light, rough running, and reduced performance. Diagnostic code P0304 repeatedly returned. Replacing the #4 spark plug temporarily restored normal operation, but the misfire returned after a few hundred miles. The #4 plug was wet/oily, and fresh oil was found pooled in the #4 intake port while the other ports were dry. All eight spark plugs, ignition coils, and plug wires were replaced, along with the #4 fuel injector and both #4 valve-stem seals, but the misfire persisted. A valvetrain/lifter tick later became audible near 3,000 RPM. The failure has now been confirmed as a valvetrain failure that severely damaged/destroyed cylinder #4 and requires complete engine replacement. The vehicle is available for inspection upon request. This defect creates a serious risk of severe misfire, loss of engine performance, or complete engine failure while driving.

While traveling at highway speeds on Interstate 5 in Oregon, my 2015 GMC Yukon Denali experienced a sudden, catastrophic engine failure with zero advance warning. The vehicle instantly lost almost all propulsion and power while surrounded by high-speed traffic, creating an immediate and severe safety hazard on a major interstate. The engine began making a loud, severe knocking noise, and I was forced to navigate across lanes without adequate power to reach the shoulder. The vehicle was towed and inspected by Point S in Creswell, OR, where diagnostics confirmed a P0300 random/multiple cylinder misfire, with cylinder 4 specifically misfiring. Using a stethoscope and scanner to isolate the failure, technicians confirmed a catastrophic rod knock failure at the bottom end of the engine. The vehicle was then taken to Sam’s Automotive Service, where a complete engine replacement was executed at a total out-of-pocket cost of $16,000. General Motors has a well-documented history of internal engine failures on these 6.2L V8 platforms, yet they have failed to issue a safety recall for vehicles experiencing this sudden, dangerous highway power loss.

My 6 year old son and I were coming down the road and came up on 2 deer and I was coming up on a sharp curve and when I hit my brakes my steering wheel LOCKED up completely and the steering wheel is so bent where I tried my best to control it but I failed and we hit a tree head on. Broke my nose and my sons leg broke in between the back seat air bag and door air bag

The contact owns a 2015 GMC Yukon. The contact stated that while driving at 40 MPH, the rear brakes became inoperable, causing the steering wheel to seize, with no warning lights illuminated. Due to the failure, the vehicle crashed into a tree. The contact and the contact’s child sustained injuries and were transported to a local emergency room for medical treatment. The contact suffered a broken nose and a chest fracture. The contact’s child sustained a broken leg due to deployment of the passenger-side air bag. The contact stated that the air bags deployed during the crash; however, the driver’s air bag failed to deploy. A police report was filed. The vehicle was towed to the contact’s residence. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was not available.

There is a recall on my 2015 GMC Yukon, that I am not the original owner of. The recall is for the brake booster and says that it expired. I have had the car checked by two different shops (both confirmed it was this), and one of them was the local GMC dealership by my house. I called to make an appointment for the recall to be fixed, to which they said they needed to order parts and it would take a few weeks. I dropped the car off three weeks later per their request for then another person to call me and say they won't fix it because it is expired. It is a safety matter that the breaks don't work occasionally.

The contact owns a 2015 GMC Yukon. The contact stated that while in reverse(R), the vehicle jerked while depressing the accelerator pedal. There was no warning light illuminated. The contact became aware of fluid spots on the driveway while the vehicle was parked. The vehicle was taken to an independent mechanic who discovered a leak in the transmission oil cooler line. The dealer then informed the contact about NHTSA Campaign Number: 14V152000 (Power Train); however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was notified of the failure and transferred the contact to the NHTSA Hotline to report the failure. The failure mileage was unknown.

Noticed a tick sound. Sent to dealer. Lifter failed. Bent push rod. Took it in Nov 24th. Charged $7,100. Fixed all lifters and bent push rod. Was turning around in my driveway and vehicle just shut off. Took it back to same dealer in Jan 27th. Bad lifter. Same push rod. Still in shop. That’s two months and 2,000 miles and had same failure. That is absolutely ridiculous GM and I should be compensated for this. It has costed me $7100 dollars. They are fixing with a two year warranty but if the failures are so close together, who’s to say it won’t just keep happening. Not only is it a safety issue, it is hurting my finances. I drive this vehicle 2 miles to work at 25 mph, and religiously change the oil at 3,000 miles. It didn’t even get an oil change before it failed again. I am not happy and GM needs to be sued for this. I owe 20,000 on this truck and have spent 7,000 already, and it keeps failing. There needs to be a recall for this model year, and it needs to be a permanent fix. GM knows the quality of this motor is horrible and they won’t do anything about it. It’s not safe. They can my truck for $20,000

Electric Power Steering (EPS) assist was lost while I was driving the vehicle. As a result, I had difficulty steering the vehicle without power steering and almost caused a crash.

While driving my 2015 GMC Yukon Denali on the highway, the vehicle suddenly began shaking and lost power. I immediately exited the highway for safety and had to “nurse” the vehicle about two miles at 10–15 mph to reach home. The vehicle would no longer run afterward. A mechanic later diagnosed a lifter and camshaft failure. This is a known and common issue with GM 5.3L and 6.2L engines that poses a serious safety risk when it occurs at highway speeds. No warning lights or prior symptoms were present before the failure. I did not report it to the dealer, but the vehicle had to be towed to a mechanic for diagnosis. The vehicle is available for inspection.

6.2L engine, collapsed hydraulic lifter AFM failure, required $7400 in total repairs. All lifters, camshaft, high pressure fuel lines, high pressure fuel pump, intake manifold & miscellaneous parts and gaskets replaced by selling Dealer at 94000 miles. No help of any kind from GM or Dealer. This is a WELL KNOWN FAILURE FOR THESE ENGINES!

I bought a car in early 2024 ive had it for 1.5y I recently went to trade it in for something more suitable for me and they ran a carfax and mileage rollback popped up and I had no clue to begin with. They rolled back 100,000 miles on the vehicle. They’re blaming the finance company but they can’t because the finance company never had the vehicle in there possession

Started my 2015 Yukon XL, drove approximately 6 miles to get gas and was to head out onto the highway. After gassing up and starting engine it began to idle very rough with a shake going on and ticking noise. No previous signs of any issues. Slowly drove back to my house at 20 miles an hour and called Mandal GMC dealership. They suggested having it towed to them for inspection. Upon inspection they said the AFM/DOD #1 exhaust lifter was bad and needed replaced. They replaced all of Bank one lifters and said their was no damage to camshaft. Drove it that night after repairing it and everything seemed fine. They called the next morning and said when they started it up the ticking was back again. They then supposedly took off head cover and inspected the camshaft again and said it was damaged and I would need a new engine to the tune of $18,000.00. I purchase it in 2021 from them use and paid $33,000.00 and now still owe even more than the engine repair. I said it would cost more than the vehicle was worth and they had done $4,000.00 of repair that didn’t even get the issue fixed. I am a senior on Social Security and can not afford to continue to pay 20,000.00 for the loan and then another $18,000.00 for a faulty engine design that caused the problem in the first place. May have to join the thousands of others in the class action to get GM to not put out such untrustworthy engineering. Now $37,000.00 piece of Yard Sculpture !! The morning that it occurred was the first sign of f

The Yukon was driving normally and just lost power while driving 55mph on the highway. Then I got off the highway to pull over and check it out and the Yukon started shaking while running and in Park. The truck would not drive over 30mph without shaking and what sounds like misfiring.

With my child in the car, on a highway with no shoulder, I experienced lifter failure. It caused the vehicle shake and lose power with cars driving behind me at 55-60 MPH with nowhere to pull over. The engine just stopped as I was finally able to make it to a driveway safely. Problem was identified by dealership and my engine had to be rebuilt. I purchased the car second hand 3 months prior with no warning or symptoms. The car was inspected at the dealership by the extended warranty company rep. The extended warranty only cover a portion of the cost. The collapsed lifter cause damage to the camshaft and bent rods. The car only had 107,000 miles. If I were not able to pull off before the engine stopped, my daughter and I could’ve easily got rear ended on a Major state highway. The car was difficult to control due to the engine shaking the entire SUV.

Fuel line rubs between cab and tank making a hole. Fuel pours out on when driving or running. Huge fire risk. Glad I caught it before the car burned up with us in it.

My vehicle is currently in the shop getting the motor worked on for a bad lifter. From the information the mechanic provided me this is a common issue with the vehicles that have the Active Fuel Management system. They are seeing many of these vehicles have to come in and have very expensive repairs. My first quote I received was $16, 000, they told me I needed a whole new motor and this assessment cost me $365 and a rental car while they looked at the truck. Now it is in the shop again and the estimate is $6000 to machine the cams as there are metal shavings in my oil. I had to again rent a rental vehicle and have not had my truck for a week. This is the third mechanic that has seen multiple of these motors have to be replaced or repaired due to this issue. I kept up on my oil changes and other recommended car maintenance and so did the owner before me. I had my last oil change approx. a week before the loud ticking noise began, then my vehicle began to have a noticeable loss of power when driving and eventually began shuttering and my check engine light began to blink and I took it to the shop. A year ago I had to replace my tail lights. I was able to find where others were recalled by my VIN for some reason was not included in the recall. They started shorting out and working only part of the time which is very dangerous when stopping, especially at night. I had them replaced and paid almost $700 for the two back lights.

Gas line leak

The brakes are hard to push to come to a stop. I brought it to a mechanic and he said it was my vacuum pump. The air bag light comes on when you hit a hard bump in the road.

1) Wiring harness to the wireless charging pad on the center console that is wired through the door hinge. Shorts out when opening or closing center console. 2) Caused a fire that led to smoke and melted components inside center console hinge. Caused smoke and awful plastic burning smell while my kids and I were parked. I had just started the vehicle. My two kids and I had to jump and run from the vehicle. 3) No, but by many forums that dealers and mechanics are aware of this issue and charges you hundreds to fix it when it is MANUFACTURE ERROR. 4) This vehicle has been inspected many times. By all the other inspection laws Missouri has in place. How has it gotten passed many times with this known issue? 5)NO! This put mine and my kids life at risk. It is a known and wide issue yet no one takes this seriously. As it just affected me and my two children, I hope this is taken seriously. Hold manufactures responsible and dealers for selling vehicles with these known issues. Protect people.

While I’m parked or even driving I keep getting a alert on my speedometer ( Trailer Break System ) and it’s not a 1 time alert the whole time I’m driving it’s constantly alerting me yet I don’t even use my Trailer system at all, it’s concerning due to the distraction of trying to clear the screen constantly while I’m on the high way.

My 5 children and I experience a traumatic experience in afternoon traffic as my 2015 GMC Yukon failed to pick up speed while waiting to make a left turn at a traffic light. The vehicle - no matter how hard I pressed on the gas didn't accelerate immediately which almost cost an accident. The vehicle rode smoothly for a few minutes then out of nowhere - it started jerking and stuttering bad for 15 seconds or so then would go back to riding smooth. When pressing the brakes - it seems to "lock" to a certain extent, so I have to press really hard on the brake to slow down/stop the vehicle sometimes makes a strange noise when doing so. I took the vehicle to be accessed by a service center in my area - it was at that time that I was told that my vehicle issues are known common GMC issues in these vehicles & more unfortunately. It's unfair to be penalized with an expensive transmission repair when these issues are known to the manufacture but not the consumer - despite being "VIN specific" as told by GMC customer service. This vehicle is needed as it is utilized to transport my children however, it's unsafe at & parked in my driveway. I was directed to reach out to GMC for remedy of the identified issues.

Air intake stayed on after shutting vehicle off and locked. It seemed it was in auto start mode from the key fob. Now it is hesitating to go and struggling to switch gears. Local mechanic is unable to pinpoint issue. Will bring to GMC dealership next. The rear camera intermittently works. If you open and close it sometimes it will fix it. USB ports intermittently work. Both taillights had to be replaced due to intermittently going out. Both front heated seats only work on top.

My breaks stop working in drive through, pulling in parking spots, backing out, slow speed of traffic. I found out it's the power break vacuum pump. It then says Service brakes on my dash when it occurs. This started about 2 weeks ago.

UPPER ARM CONTROL SCREW LOOSENED UP. Drilled hole on axle.

Both tail lights fail. I just bought this vehicle at Ewald Automotive in Oconmowoc Wi a month ago with 100k and I know they were aware of the problem and so is GMC. I am not paying 900 bucks for each tail light. They are absolute junk. The left side someone already messed with it because there is electrical tape on it. Ewald laughed in my face.

On, 9/27/23, I took my son to daycare around 9 am and went to Norfolk, NE for the day. I ran errands and had an appointment which my car sat in the sun for 1.5 hours at one time. Between stores we turned the air on as I had my oldest child with me. We came home to West Point, NE and picked up my other children about 4 pm. All car seat buckles were in normal working condition. I parked my car back in our attached garage on the East side of our house. Around 7:30 am on 9/28/23, I attempted to buckle my son again and noticed the male end of the chest clip was severely bent as if it had melted. My car has tinted windows in the second row where the car seat is located. The car sat in the sun, but not directly on the carseat, for the 1.5 hours while we were at the appointment. The car seat may have had direct sunlight while we were eating lunch which was no longer than 30 minutes. The car was again in the sun for another 2 hours but the carseat was not in direct sunlight during that time. Luckily, I had a spare carseat and was able to discontinue use of the car seat with the melted chest clip. I would not have been able to buckle the chest clip in the condition it was in on 9/28/23 ensuring the shoulder straps would be in the correct position on my child. The car seat has not been inspected by anyone other than myself.

I have owned this vehicle almost 6 years, 40,000 when purchased used. Since purchase, we have had multiple issues with the trailer brake system randomly going off, dinging non stop, we had the problem serviced under our warranty and is now going off again. We do not tow but a few times every summer which is our jet skis however. This has happened multiple times prior to us using our warranty, the garage says they fix it but it keeps happening. I am very frustrated that I can't drive my vehicle down the road without a continues dinging. I looked up what "trailer brake system" means and found that it can be very dangerous and GMC's are known to have this problem, it is suggested that I lodge a complaint in hopes of getting this problem resolved from the manufacturer before a driver becomes seriously injured when the braking system decides to fail. I have read complaint after complaint. My warranty is now expired as I recently rolled over 100,000 miles, the GMC garage told me the part was around $78 but over $400 with install, ridiculous! I have already replaced this part a little over a year ago, I went to the garage where the warranty work was performed and got all the paperwork. Why has this problem not been categorized as a recall at this point? Something isn't right!

Consuming a lot of oil, makes a funny clicking noise sometimes when accelerations, had lil pieces of metal in my oil, Transmisson problems, 1 front headlight and all rear tail lights went out, trailer brake system would come on and go off now it won’t stop dinging and makes a whole bunch of other lights come on (trailer brake system, park assist, low brake fluid, traction control, collision) dings some much I can’t drive it. Called a gm shop near me and they told me it would cost a whole bunch for each diagnosis for every warning that came on.

The contact owns a 2015 GMC Yukon. The contact stated that on several occasions while driving at an undisclosed speed, the steering wheel became stiff and difficult to maneuver. The contact stated that while making a turn, the steering functionality momentarily returned however, the failure recurred. The contact stated that while driving at an undisclosed speed, the steering wheel stiffened and became difficult to maneuver then remained stiff. The power steering assist warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the electrical power steering failed and needed to be replaced. The vehicle was not repaired. The contact was then advised to take the vehicle to the dealer and informed that the vehicle was included in a recall and provided the NHTSA Campaign Number: 14V719000 (Steering) however, the dealer and manufacturer were notified of the failure and the contact was informed that the VIN was not included in the recall. The failure mileage was approximately 150,000.

Fuel pump leak. our cabin fills up with exhaust causing myself and my 3 young kids (1,3,5) to start coughing, eyes and throat burning, headaches & a hard time breathing. confirmed by GMC dealer in concord & separate auto shop. They told us it had a recall and that they couldn't fix it after paying them to diagnose it since it was recall. Now GMC dealer is telling us that the problem and recall exists for other 2015 Yukon models but our VIN # Is not included and that's why they never fixed the problem that I've been complaining about since I bought the truck (dont remember exact purchase date but the vehicle was new and under warranty for years). I've taken it to the dealership 3 times for the same problem (exhaust smell in cabin) and they kept saying it's fine. Now it's so bad that we can't drive it because it makes us feel sick.

The taillights started to randomly go in and out. The driver side taillight stopped working but the passenger side taillight still worked. Then a day later the driver side taillight worked, but the passenger side taillight didn’t work. The next day we were going to look into this issue, and the driver and passenger side taillights were working, so we halted. We kept an eye on it and they seemed to continue to work for a few days with no issues, so drove it 20 miles to work. When I left work it was dark and I had a coworker check my brake lights before leaving and the running lights and brake lights were indeed working. By the time I arrived at home, I had no running or brake lights. This is and was a danger to others and myself as this could’ve caused an accident driving and the taillights going out. The truck did not give a warning message that I had no taillights.

“Service Trailer Brake System” indicator light and alert continue happening. As of this weekend, my rear driver side taillight has begun going in and out/off and on.

I write to express my concern over an issue with my 2015 GMC Yukon that has also impacted other community members. In April, my Yukon, with just over 70k miles, broke down as I was turning from Rte 14 in Pembroke, MA onto Rte 53. At the time, I had my 3 & 5 year old children in the car with me. I could not get my vehicle to restart & had it towed to a local mechanic. After our local mechanic could not diagnose the problem, on 4/25/23, I had the vehicle towed to Marty’s GMC in Kingston, MA, where it was purchased. I had to call Marty’s regularly to check in on my vehicle before it was finally inspected. After 2 weeks, I was told that the valve spring needed to be replaced & the fluids flushed. I approved those repairs totaling $1600. After a couple of days, I received a phone call that there are issues with the lifters & brakes which would add another week of repairs & bring the costs up to $5,500. After another week, I received a call that there was more work to be done increasing the total cost of repairs by an additional $1,000. When I finally picked the car up, I was notified that the estimates I received were miscalculations & my repair costs totaled $7,512.23. Since this ordeal, I have talked to several GMC owners with cars of a similar age & low mileage. These owners have experienced the exact same issues. Throughout my conversations, I learned there is a service bulletin out on the issue with the lifters, but no recall. The lifter issue is a serious safety hazard. I ha

Both tail lights have stopped working. I purchased in 2019 with 60k miles and by the time the first tail light failed, I was over the 72k limit. If these lights failing was an issue before, it still is an issue and the special warranty should be extended to ensure replacement of faulty items.

When turning left the vehicle locks up and turns off, after that messages about the parking assist and versatrack starts popping up.
