POST-RECALL 25V274 ( & EA25007, EA25001) EXHAUST INTRUSION WITH CARBON MONOXIDE POISONING HAZARD Following the complete engine replacement under GM recall N252494000, my vehicle has developed a severe and persistent exhaust intrusion that allows toxic exhaust fumes, including carbon monoxide (CO), to enter the passenger cabin. CO levels have measured a peak of 83 PPM and consistent reading between 20-37 over multiple tests. PATTERN OF POST-RECALL EXHAUST SYSTEM FAILURES Vehicle has been in for service 6 times, over 100 days, as part of the engine replacement plus (metal found in the oil pan). Since recall, the vehicle has had an exhaust smell and noise rattle issue with the following exhaust system components deemed failed and been replaced: 1. Radiator cap (leaking onto exhaust) 2. Exhaust muffler (replaced TWICE - June 2025 and August 2025) 3. Exhaust clamps (leaking) 4. Left exhaust manifold (warped) Critical Finding: Despite replacement of virtually the entire exhaust system, the defect persists. This suggests a fundamental design or installation defect related to the engine replacement procedure, NOT isolated component failures. Documented Carbon Monoxide Levels: Between January 30 and February 3, 2026, I conducted 15+ tests using a professional-grade Klein Tools ET180 Carbon Monoxide Meter. Results: • Peak reading: 83 PPM • Multiple readings: 40-72 PPM sustained for 6+ minutes directly at my [XXX] daughter's car seat position • Testing method: Vehicle started via remote start, CO meter placed in cabin, readings recorded over 10-15 minute periods Health Impacts to Family: • Wife and [XXX] daughter consistently experience dizziness, headaches, and nausea when riding in vehicle • Daughter now refuses to ride in vehicle because it makes her feel sick • Symptoms consistent with carbon monoxide poisoning Independent service station verification on January 30th confirmed "vehicle is dangerous to operate with children inside and needs immediate service."

During the operation of my 2023 GMC Yukon XL AT4 on [XXX], carbon monoxide (CO) entered the cabin, exposing my children and me to dangerously high levels of CO and causing confirmed carbon monoxide poisoning. We were driving with the engine running and the heater on for approximately 21 minutes when the exposure occurred. Symptoms began to escalate that day and into the proceeding days, including severe headache, stomachache, pallor, chest pressure, shortness of breath, fatigue, and neurological issues. My children, particularly my [XXX] and [XXX] , experienced the most severe effects— both were very ill especially my [XXX] . Unfortunately, we initially did not believe it was possible for CO to enter the vehicle cabin, which delayed early intervention and appropriate medical care. Blood testing 4 days later confirmed elevated carboxyhemoglobin levels in my [XXX] , the only one tested. During the incident, the battery warning light was the first indication of trouble, but soon after, many additional error messages began flashing on the dashboard. The vehicle then overheated, decelerated, and eventually shut down while driving. We were in the vehicle under 21 minutes. Upon inspection after the incident, my husband noted a severed belt and potential pulley issues. The exact cause of the CO intrusion has not yet been identified. The vehicle is available for inspection and unaltered to preserve evidence. I am writing GMC and requesting further investigation by GMC. This incident reflects a severe safety issue with potentially life-threatening implications for GMC owners. CO exposure can cause significant harm, and delayed identification in this case placed my family at substantial risk. Immediate investigation and corrective action are essential to prevent similar incidents from occurring in the future. Time is critical, as this defect could have catastrophic consequences for other unsuspecting drivers and their families.

Rear wheel lock up It took two Dealership is going through it's diagnosis but says it needs new valve body upgrade. Been sitting in the shop for 2 months
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.
While driving in a gravel driveway, the window curtain airbags and the middle console airbags deployed, with no collision what so ever causing injury to the driver and should you have a child this could have been very damaging as the airbags came out in all the way back through the vehicle. This incident was inspected by police and fire as OnStar called them as it detected a collision, and without the vehicle being moved from the location the officer said there is nothing that should have caused the airbags to deploy, there is absolutely nothing here in this driveway that could have possible caused airbag deployment, The running boards go in and out, even when on the interstate constantly, and when backing up or going forward at times, and especially in a gravel driveway your automatic breaks will stop you abruptly, so fast that your seat belt will lock up on your and thrust you forward and backwards. The rear entertainment system will screen at times when turning it on will stay black and you have to keep turning it on and off to get a screen to show. No warning lamps or messaging with any of these cases.
On August 17th, 2026 while approaching a nature preserve entrance at approximately 1 mph, my 2023 GMC Yukon Denali Ultimate suddenly accelerated on its own, without the driver pressing the accelerator pedal, striking a split-rail fence and a tree. Airbags did not deploy. The front collision system didn't issue any alerts about the fence and tree. A GM software update had been installed a couple of days before this incident . In the weeks prior, the vehicle had also intermittently failed to hold side mirror position and periodically failed to deploy the power running boards. I request that GM and NHTSA investigate a possible link between the recent software update and an unintended acceleration event, potentially related to the adaptive cruise control or another driver-assist/body control module.
The contact owns a 2023 GMC Yukon. The contact received notice of NHTSA ID Number: 25V274000 (Engine and Engine Cooling). The contact stated that while driving on several occasions at various speeds, he and his wife observed noises emanating from the engine compartment. On another occasion while driving and coming to a stop, the vehicle stalled, and a "transmission unable to shift" message appeared. The gear selector was placed in park (P), and the vehicle was restarted, after which it drove normally. The vehicle was taken to a dealer, but it was not diagnosed due the manufacturer only allowing certain vehicle to be repaired at this time, even with the failures that had transpired, and no repairs were made at that time. The contact stated that while driving home in pitch darkness at approximately 30 MPH on a windy road, the vehicle stalled. While attempting to steer the vehicle off the road, it remained halfway in the street and nearly caused over 15 accidents. One near-accident involved a motorcyclist who came around a turn, narrowly missed the vehicle, fell into the street, and was almost hit by oncoming traffic. No police reports were filed as the police could not assist at that time. The contact and her daughter did not sustain injuries but were severely traumatized. It was uncertain if the motorcyclist sustained injuries. The contact stated that when the vehicle was being towed, it would not go into neutral, and the contact observed the frame cracking while being hauled on the tow truck. The manufacturer was notified of the failure but did not provide assistance. The failure mileage was approximately 18,000.
The contact owns a 2023 GMC Yukon XL. The contact stated that while driving 70 MPH, the vehicle stalled, and the engine seized. There was no warning light illuminated. The vehicle was coasted to the side of the road. The vehicle failed to restart and was towed to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was repaired. The contact stated that the vehicle had previously been repaired under an oil consumption-related recall. The manufacturer was made aware of the failure by telephone, and a case was opened. The failure mileage was approximately 34,000.

Catastrophic engine failure and sudden loss of propulsion on a highway after completing GM's OW-40 oil recall remedy.
After engine passed check for possible replacement because of recall, engine failed 5000 miles after. Even though I have a new engine now, there is no warranty coverage other than the lower part of the engine. I am already having misfire issues.
I was Driving down the interstate when the RPMS on my car increased and my car started to shutter. I went to get off the roadway and it put itself into neutral and lowered my speed. when i got On the shoulder it stalled and would not turn back on. I had To be towed. To this point, my car has been in the shop for over a week with no solution.
PICO scope test #FDYZ295894391 on engine for recall #N252494003 engine , passed test. Drain oil filled with 0-40 replaced oil cap. Date 09/19/2025, mileage in 20142/mileage out 20142. Vehicle runs rough. Not stable at times. Vibration noise coming from the motor at times.
I am reporting a severe, recurring, and life-threatening manufacturing defect involving a sudden, catastrophic loss of motive power at highway speeds on the interstate. This vehicle has suffered two identical valvetrain failures that placed my passengers and nearby motorists in extreme danger. Incident 1 (Approx. 40,000 miles): While traveling at high speed on the interstate, the vehicle violently shook, all engine warning lights flashed, and the engine suffered an immediate, near-total loss of propulsion. The vehicle was towed to an authorized GMC dealership, where technicians diagnosed a collapsed Dynamic Fuel Management (DFM) hydraulic lifter in Cylinder 3. The lifter bank was replaced under the factory powertrain warranty. Incident 2 (Approx. 77,000 miles): While driving at high speed on the interstate, the exact same vehicle behavior occurred. The engine suffered a sudden, total loss of power, and all dashboard warning lights illuminated simultaneously. Out of absolute necessity and to avoid a catastrophic high-speed collision on a dangerous stretch of highway, the severely crippled vehicle had to be forced through active interstate traffic without proper engine power all the way to my home. The vehicle has since been inspected by a GMC dealership, which has confirmed that the exact same Cylinder 3 lifter has failed a second time. The dealership and the GMC Regional Service Manager are currently refusing to honor the 24-month dealer-installed service parts warranty, demanding an out-of-pocket deposit of $5,000, and denying alternative transportation. GM's failure to permanently remediate this known, systemic valvetrain defect has twice left me navigating a failing vehicle through high-speed highway traffic, heavily compounding the safety risk.
