The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 43
Against the median year of the GMC Yukon XL. 50 means typical for this
model; 100 means roughly double.
Severity — 0
0% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
100% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.

NHTSA investigations into the 2024 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 2024 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.

General Motors, LLC (GM) is recalling certain 2023 Chevrolet Silverado 1500, GMC Sierra 1500, 2023-2024 Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL, Cadillac Escalade, and Escalade ESV vehicles. The electronic brake control module software may fail to display a warning light when a loss of brake fluid occurs. As such, these vehicles fail to comply with the requirements of Federal Vehicle Safety Standard number 135, "Light Vehicle Brake Systems."
Risk: Without a warning light, the vehicle may be driven with low brake fluid, which can reduce braking performance and increase the risk of a crash.

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.

The contact owns a 2024 GMC Yukon XL. The contact stated that upon taking the vehicle to the dealer to be repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling), the contact was informed that the vehicle passed the inspection and no repair was needed. However, the vehicle experienced engine failure approximately seven months later. While driving 50 MPH, the vehicle lost motive power. There was no warning light illuminated. The driver pulled over, restarted the vehicle, and resumed normal driving. The vehicle was taken to the dealer the following morning, where the Electronic Control Module was replaced under warranty; however, the failure recurred while driving 70 MPH three weeks later. No warning light was illuminated. The driver pulled over, restarted the vehicle, and resumed driving; however, the vehicle failed to exceed 40 MPH and shut off. The vehicle failed to restart and was towed to the dealer, where it was diagnosed and determined that the engine, radiator and seal kit needed to be replaced. The vehicle was not yet repaired. The contact was concerned that the recall remedy failed to prevent the failure. The manufacturer was notified of the failure and a buyback was requested, but the request was denied, and the contact was referred to the dealer for additional assistance. The failure mileage was approximately 27,800.

We're in the waiting period for our 3rd engine. 1st engine failure, while driving on interstate at 70+ MPH, engine stopped running, causing a very unsafe condition for family and surrounding vehicles. Engine failure 2 days later, towed to dealership for inspection, replacement engine was installed ~4 weeks later. 2nd engine failure, while driving on interstate at 75+ MPH, engine seemed underpowered and would rev upwards of 6000+RPMs, not exactly unsafe, but not usual operating conditions either. Returned to dealer, upon inspection, total engine replacement was recommended.

I perform all maintenance on my vehicles, I have previously been a ASE Certified Master Technician, so I know engines and vehicles very well. Vehicle is outside of current engine recall window due to the engine build date being July 15, 2024. Engine was over maintained, oil and oil filter changed 6 times in 17,732 miles, first oil and filter change performed at 544 miles, when 5W30 oil was put in engine, installed a magnetic drain plug and installed Filter Mags on oil filter. Ran 5W30 oil for 2 oil changes, then moved to 0W40 oil. Oil analysis performed for each oil change. Results were looking acceptable up until the next to last oil change at 13,801 miles. Changed engine oil and filter on 6/12/2026 @17,732 miles. Found a heavy build up of metal particles on the magnetic drain plug and when oil filter was cut open there was a heavy build up of metal particles where the Filter Mags were located and the filter element had fine metal particles in entire engine oil filter element. The engine has made no noise and is still running, but based on the evidence the engine is currently failing and if I would have continued to drive it, the engine would likely lock up on the highway. CLEARLY GM DID NOT solve the crankshaft problem July 1, 2024 and CLEARLY using a higher viscosity oil like 0W40 will not keep these engines from failing. If I would have continued to drive the vehicle and if I would have not changed oil and found metal in the oil, this engine would have absolutely failed on the highway. This vehicle has over 80% highway use.

2024 Engine failed while moving at 70mph out of state. De-accelerated rapid as I was changing lanes and was almost hit by two vehicles. Once of the interstate, I made it to the shoulder of an exit ramp that was a blind spot. Cars exiting to this ramp almost always had to veer to keep from hitting me. I purchased this vehicle in October 2024, never knew anything about a recall, was never disclosed to me about recalls. To this day, if I enter my VIN, there is no recall and I have never received any communication stating this vehicle was on recall. I complained to the dealer twice about unusual noise from vehicle, which they dismissed. I took it back to the dealer because my oil light indicated I was "low", this oil is too low, my concern was a leak. Took into GMC dealer, they stated we did not see any leak. Now this. Problem, GA law states in order to qualify for buyback, 24,000 miles or under 2 years. Well, I have 24,986...this automatically disqualifies me. SMH The options I was given are all a NO WIN for me! I was almost killed on the interstate, not to mention the level of stress and issues this car nightmare has caused me. $100k vehicle and I still owe 87K

Also everyday my vehicle keeps saying software update even I installed the update and it says complete. I know GM is not updating my vehicle software everyday.

Purchase this Vehicle November 1st 2025 as a GM certified used vehicle. Had several issues with the camera system including the backup camera. Would go offline and not be usable for days. Vehicle went back to shop several times for this with no resolution. Now February 18th 2026 at approximately 630PM EST (after sunset) on the way into work traveling on the highway the engine lost power and engine shutdown. Vehicle shifted into neutral with the indication to press the start button in order to shift into Drive. This cause all of the lights to shutdown when it tried to start the engine. I was barely able to pull this over to the shoulder before I lost forward motion. Narrow shoulder. Tried to restart again with the same results. Call towing company. They attempted to jump start vehicle. Same results. All power shutdown. Truck was loaded onto flatbed and towed to dealership. Dealership states bad battery. Got authorization to replace battery from the dealer in which I purchased the truck. hey attempted to start and then it burned out the main fuse. They determined that the engine had seized and they were going to replace the engine. I looked up to find that GM had performed the engine oil replacement procedure in June of 2025. This vehicle is listed in the "recall" for defective L87 engines. Clearly changing the oil had no effect to remedy the issue. I have no faith that the new engine will not fail the same way this one did.
