NHTSA investigations into the 2023 GMC Yukon XL
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Recalls on the 2023 GMC Yukon XL
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 202522549,848 units in Canada
Engine
Issue: On certain vehicles, the connecting rods and/or crankshaft components may not have been manufactured properly. As a result, the engine could make abnormal noises and a warning light may turn on. If you continue to drive the vehicle with these symptoms, the engine could fail. Note: This recall only affects certain vehicles equipped with a 6.2 L V8 gas engine. Safety Risk: An engine failure could cause a sudden loss of power to the wheels and increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and advise you to take your vehicle to inspect and, if necessary, repair or replace the engine. For vehicles that pass the engine inspection, the dealer will replace the oil with a higher viscosity oil, install a new oil fill cap, replace the oil filter, and add an insert to the owner's manual.
Recall 202451938,382 units in Canada
Lights And Instruments
Issue: On certain vehicles, a software problem could cause the low brake fluid warning lamp not to turn on if the brake fluid level gets too low. A low brake fluid level can cause reduced braking. Safety Risk: A driver that isn't aware of a low brake fluid level could experience reduced braking and an increased risk of a crash. Corrective Actions: General Motors will notify owners by mail and send a wireless over-the-air software update to eligible vehicles to update the electronic brake control module software. Alternatively, you may schedule an appointment to have the update performed at a GM dealership.
Recall 2024060273,306 units in Canada
Lights And Instruments
Issue: On certain vehicles, a software problem could cause the lower beam headlamps not to turn on as it becomes dark outside if the multi-function switch is in the "OFF" or "PARKING LAMP" position. This could also cause the daytime running lamps (DRLs) to turn off when the vehicle is moving. As a result, the vehicles may not meet certain requirements of Canadian regulations. Safety Risk: Headlamps and/or DRLs that don't turn on could reduce visibility, make the vehicle less visible to others and increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and advise you to take your vehicle to a dealership to update the body control module (BCM)software.
Recall 2023472163,611 units in Canada
Lights And Instruments
Issue: On certain vehicles, the automatic headlamps may not turn on soon enough as it becomes dark outside. Canadian regulations require automatic headlamps to turn on when the ambient light level drops below a certain point (1000 lux). Safety Risk: Headlamps that don't turn on as it becomes dark outside could reduce visibility and increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and send a wireless over-the-air software update to eligible vehicles to update the body control module (BCM) software. Alternatively, you may schedule an appointment to have the update performed at a GM dealership.
Recall 202270085,685 units in Canada
Lights And Instruments
Issue: On certain vehicles, the daytime running lamps (DRLs) may stay on when the headlamps are on. Canadian regulations require the DRLs to turn off when the headlamps are on. Safety Risk: Daytime running lamps that stay on could cause glare for oncoming drivers and increase the risk of a crash. Corrective Action: General Motors will notify owners by mail and instruct you to take your vehicle to a dealership to update the body control module (BCM) software.

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."

ENGINE AND ENGINE COOLING
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.

VEHICLE SPEED CONTROL
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.

Vehicle shifted into neutral while driving down the highway, extremely dangerous. Would not shift into gear and could not accelerate. Was able to pull over and the vehicle would not restart. Had to have the vehicle towed to a dealership. Dealership found a blown fuse, problem happened again twice and the dealer could not find the problem. This was July 28th, 2026. On August 20th, while in cruise control, slight ringing noise began, then a loud thump, then a loss of oil pressure. Unable to do anything other than pull over on an interstate with my family. Again, very dangerous. The vehicle would not restart and could not be shifted out of park. Had to have the vehicle towed again. Have also had at least 8 recalls on the vehicle. Unbelievably dangerous situations with my family, aside from inconvenient and expensive.

POWER TRAIN
My 2023 GMC Yukon Denali XL, used as a commercial vehicle for my business, experienced sudden and complete engine failure at approximately 70,000 miles with no prior warning. No check engine light, no unusual noise, and no other symptoms. The vehicle had previously been inspected/serviced under GM Safety Recall 25V-274 (L87 Engine Loss of Propulsion) and had been deemed safe prior to this failure. The failure occurred while driving on a two-lane road in Durango, CO. The vehicle lost all propulsion and came to a stop in the roadway, blocking the lane of travel and forcing other vehicles to cross into the oncoming traffic lane to go around the disabled vehicle. This created a serious and immediate hazard to myself and to oncoming traffic. The vehicle was not driveable and had to be towed. The dealer confirmed catastrophic engine failure requiring a complete engine replacement. After the engine replacement, the Morehart Murphy GMC dealership in Durango also failed to properly recalibrate vehicle sensors. They did not reinstall certain suspension components that had been removed for the engine replacement, requiring multiple additional dealership visits to resolve along with recalibration of the air ride suspension. After the replacement I was getting messages that the vehicle was "too low to drive with caution" and "Reduced Acceleration Drive With Care." This vehicle failure occurred during our peak season (June 10-July 2). The vehicle being out of service, I was required to rent a replacement vehicle at my own expense because GM did not provide a loaner vehicle. I estimate loss revenue at $1k/day. When I attempted to raise this issue with GM directly, their response was to submit letter to a P.O. Box, with no other means of resolution or contact offered. Given that this vehicle had already undergone the recall remedy and was represented as safe, this incident is relevant to NHTSA's ongoing investigation into post-recall L87 engine failures (Recall Query RQ26001).

2023 GMC Yukon XL(6.2 liter engine).Engine has failed twice with the first incident being on the interstate and the engine seized without warning with only 38,000 miles. GMC replaced the engine and now the second engine has failed with only 80,000 miles on it. I am told there needs to be a third engine installed and the vehicle is only three years old. If an engine fails without warning this puts everyone in danger. My [XXX] son was in the car when the first engine failed. There is an obvious manufacturer's defect that needs to be addressed before innocent people are injured or killed. The vehicle is currently located at Darrell Waltrip GMC in Franklin, Tennessee.

SERVICE BRAKES
I got into my car to run some errands. As I drove away from my house, I made a left turn downhill. I noticed vehicles ahead, so I began to slow down. At that moment, I was driving between 20 and 25 mph. When I tried to brake, my brakes failed and started flashing a brake failure warning light. I kept pumping the brake pedal, and eventually, the car slowed down and came to a stop. I turned on my hazard lights, and immediately returned home. My nephew and I were both in the car. Our live flashed in front of us. Thankfully, there were no vehicles directly in front of me or pedestrians. This could have turned out to be the worst day of my life if anyone had been injured.

After driving the car for three years and taking the advice of the dealership and resetting the infotainment center every few weeks, the problem escalated and started freezing up at least once a week to eventually doing it every day and the heart reset wouldn’t always work the first time. Dealership eventually confirmed it was a defective radio module. This is a very large vehicle and the rearview camera is an essential necessity to avoid collision.

FUEL/PROPULSION SYSTEM
On July 14, 2026, I experienced a serious fuel system failure with my 2023 GMC Denali. That morning, I filled the vehicle with a little over 20 gallons of fuel at a gas station approximately two miles from my home. Later in the day, I made a short trip to my neighborhood swimming pool, roughly 1.5 miles round trip, with no unusual noises or warnings from the vehicle. Approximately two hours after returning home, I entered the vehicle to run an errand. When I shifted into reverse and began backing out of my carport, I immediately heard a scraping noise on the concrete. I stopped the vehicle and inspected underneath. At that point, I discovered that the entire fuel tank had fallen out of the vehicle and was resting on the ground. I contacted roadside assistance, and the vehicle was towed to the dealership. The dealership informed me that the fuel tank support straps were missing, which allowed the tank to detach and fall. I personally searched along all the routes I had driven earlier that day and did not locate any straps or debris. The tank itself showed no impact damage, suggesting it dropped cleanly rather than being torn loose by road contact. Although the vehicle is relatively new, my bumper to bumper warranty expired in September 2025, and I was charged for the repair. I have included photos taken before and during the tow, as well as the dealership’s invoice. I am extremely concerned about the safety implications of this failure. If the tank had fallen while I was driving at interstate speeds (approximately 70 mph), it could have caused a catastrophic fire hazard, loss of vehicle control, or danger to other motorists. I do not know how long the vehicle had been operating without fuel tank straps, nor why there were no warnings or indications of a structural issue. I also question why the dealership did not treat this as a manufacturing or assembly defect, given that fuel tank straps should not detach under normal use. ...RAN OUT OF CHARACTERS...

POWER TRAIN
While driving about 70 mph in the express lanes, the vehicle suddenly lost power and drifted like it went into neutral. There were no warning symbols. The vehicle could not restart even while coasting. After stopping, it locked itself in park and would not shift out of park. My family and I were trapped on the express lanes for over an hour in a dangerous location. The vehicle stayed stuck in park even on the tow truck. The dealer confirmed metal in the oil filter, a blown main fuse, and knocking when starting. The recall inspection and remedy were already done, but the failure still happened. The vehicle is undriveable and the required recall repair cannot be completed because the replacement engine is on backorder with no ETA.

My wife and I were traveling to Denver CO to pick up my son and grandson from the airport. The engine started to make a very exaggerated rattle. We found a dealership near our motel where we took the vehicle to and were told not to drive home that the engine needed to be replaced. We had to arrange our own transportation for both us and the vehicle 8 hrs back to our home in Rapid City, SD where our local dealership replaced the engine. The vehicle had approximately 65,000 miles when this occurred. Fortunately we were in a populated area when this occurred as there is a lot of very sparsely populated area between our home and Denver. This malfunction not only cost me a lot of money but also put my family at risk in unfamiliar areas.
