Owners have filed 37 complaints
about the 2026 GMC Yukon XL with NHTSA between 2025 and 2026.
The largest single group is the engine & cooling.
Across this model's run it ranks 26 of 27 worst.
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 — 16
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 — not reported
Too few complaints recorded a mileage to measure this.
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2026 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.

Loss of motive power due to engine failure post recall remedy
On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s reca...
Recalls on the 2026 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 202623257 units in Canada
Wheels
Issue: This recall is for certain vehicles equipped with 24-inch wheels that had a dealer-installed accessory brake package or had the front hubs replaced during service. On certain vehicles, the wrong bolts may have been used during installation of the accessory brake package or during service or replacement of the front wheel hub bearings. As a result, the bolts could loosen and cause poor handling and a loss of control. Additionally, this could cause the front wheel(s) to separate from the vehicle. Safety Risk: A loss of control could create the risk of a crash. A wheel that separates could create a road hazard for others. Corrective Actions: General Motors will notify owners by mail and advise you to take your vehicle to a dealership to replace the front left and right wheel hub bolts.
Recall 20260861,255 units in Canada
Other
Issue: On certain vehicles, the owner's manual may be missing. As a result, the vehicles may not meet certain requirements of Canadian regulations. Note: For the Escalade model, the recall also affects certain 2026 model year Escalade IQ and Escalade IQL models. Safety Risk: A missing owner's manual could cause confusion on how to safely operate the vehicle and increase the risk of injury or a crash. Corrective Actions: General Motors will notify owners by mail and advise you to take your vehicle to a dealership to install the owner's manual.

I purchased my vehicle from GMC on April 13th and had approximately 4,500 miles on it. It was sold as new and drove it for about a week at 4,994 miles on the highway. During this time, it shifted from drive to neutral , but the vehicle was towed back to the dealership. Upon inspection, it was diagnosed with a seized engine.

This is a follow-up to my previous complaint - 11716917. My second engine, which was installed after my first engine failed after approximately 5,000 miles, also failed. It failed after approximately 5,200 miles on it. I picked up the vehicle after the first engine replacement on 2/19/26 and the second engine failed on 5/18/26. It failed as I was driving to work - I was able to exit the highway and pull into a parking lot. From there I had the vehicle towed to a dealership and they confirmed that the engine had failed and needed a total replacement. This is a 2026 Yukon XL Denali Ultimate with the 6.2 L87 engine. I want to make sure the NHTSA is aware that I’ve now had two complete engine failures and am on my third. I have no confidence in the vehicle and have no reason to believe that my third engine will last. GM has refused to do anything about this vis-a-vis extending my warranty or replacing my vehicle or buying it back.

9 months into ownership, with 24,000 miles I had complete engine failure pulling into an intersection. Slamming into park while moving and shutting down. This is a known issue with the GM 6.2 liter engines but I specifically waited to order a 2026 as this was far outside the recall window GM had in place for this known issue and was led to believe the issue was fixed going forward. The car was towed to a GM dealer and sat for 39 days for a complete engine replacement. Now, a week after it has been returned it has sputtered and shut off as I am coming to a stop requiring a restart, not unlike stalling a manual transmission car. I think your agency needs to expand the investigation far further to include 2026 models. This is a 90,000 dollar brand new family hauler that I am supposed to trust my wife and kids are safe in. Now I cannot even trust it will safely take her through an intersection. Thank you for your time.

Unknown brought my car in on July 24, 2026. They reported they do not know what is wrong with the engine, but stated GM is not letting them take it apart and told them to replace the engine. While the car was parked and during acceleration, my car was making a weird noise that got louder during acceleration. A few days prior to this happening, while driving on the highway, my car's emergency lights came on. I had to pull over to turn it off.

ELECTRICAL SYSTEM
The large central infotainment touchscreen (which controls climate control/AC, navigation/maps, audio, backup camera, and all primary vehicle functions) has repeatedly failed by going completely dark/blank without warning on my 2026 GMC Yukon Denali XL purchased new on [XXX]. The screen has gone dark on three separate occasions. First failure occurred prior to [XXX]; vehicle was taken to Champion GMC (7885 W Grand River Rd, Brighton, MI 48114) for repair and returned to me. The screen failed again shortly after. Second repair attempt was made on 06/22/2026; vehicle was returned and the screen failed again immediately. The vehicle is currently at Champion GMC for a third repair attempt as of 06/29/2026. Safety risk: Loss of the screen eliminates access to the backup/rearview camera, speedometer display, climate controls (heat and AC), navigation, and warning indicators — all while operating the vehicle. There is no warning, message, or dashboard indicator prior to each failure. The screen goes dark suddenly and without notice. The problem has been confirmed and repair attempted three times by Champion GMC. The vehicle has not been inspected by police or insurance representatives. The component is available for inspection upon request, as the vehicle is currently at the dealership INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While operating the vehicle, I began to hear a metallic grinding noise originating from the center of the engine compartment. The sound was clearly audible within the cabin. Approximately one mile before the vehicle ultimately failed, the engine began to malfunction. As I slowed to a stoplight, the vehicle started to shake before shutting off abruptly and entering a coasting state. All electrical systems powered down and the vehicle would not restart. Shortly thereafter, heavy smoke began to emit both inside and outside the cabin, visibly coming from the hood and through the air vents. There was also a distinct burning odor. I attempted to restart the vehicle multiple times without success. The dashboard displayed the message: “conditions not suitable to shift.” Due to the vehicle becoming disabled on a curve and posing a safety hazard, I contacted the Sheriff’s Office for assistance to prevent a potential collision. Upon their arrival, it was noted that the engine compartment and hood area were exceptionally hot, particularly where the smoke was originating. The dealership has since confirmed they have also been unable to restart the vehicle. The vehicle has been inspected by the GMC dealer and is currently pending further evaluation by a GM-certified mechanic to determine the root cause. Prior to this incident, there were no warning lights, system messages, or other noticeable symptoms indicating an issue.

In the 2026 Yukons, almost all physical buttons have been replaced by the giant center touchscreen. When starting my vehicle, about a third of the time the screen will not come on, and can’t be turned back on by any means. It will randomly come back on after a few more trips/restarts. This renders several critical systems inoperable. All HVAC does not work, defrosters aren’t available, back up cameras and parking assist is not available, and control of any navigation functions or options (ie heated/cooled seats) are not possible. There are no physical buttons for these items, so there are no other options. Voice commands do not function properly when the screen is black, so no option there. After my third visit to the dealership and an open case with GM, they are finally authorizing a screen replacement. We will see if this fixes it. However, my previous explanations from GM pointed to a nebulous future software release, with no date or detail.

Dallas, TX
ENGINE
2026 GMC Yukon XL Denali, VIN [XXX] , 6.2L V8 L87 engine. At 3,168 miles, vehicle developed rough idle and knocking noise. Delivered to Sewell Buick GMC Dallas on 3/2/26. Dealer diagnosed crankshaft thrust bearing spun. Tech pinpointed bottom-end noise via stethoscope, found excessive metal debris in oil and oil filter. Engine teardown confirmed thrust bearing failure. Required complete engine replacement (GM #xxx), plus oil cooler/radiator, oil cooler lines, torque converter bolts, and all one-time-use parts due to metal contamination. Old engine serial [XXX] , new engine [XXX] . Repaired under warranty 3/9/26, RO #XXX. This is the identical failure mode that caused NHTSA Recall 25V-274 covering ~597,630 L87-equipped vehicles (MY 2021-2024). GM stated manufacturing improvements were completed by 6/1/24 and 2025+ models were not affected. My 2026 model year failure directly contradicts this claim and suggests the defect persists in current production. SAFETY CONCERN: Bearing failure causes sudden complete loss of propulsion at any speed. NHTSA investigation PE25001 notes most failures occur without warning. Loss of power at highway speed creates serious crash risk due to loss of ability to accelerate and reduced power braking/steering. Had this failure progressed further while driving with my family, consequences could have been severe. No crash or injury occurred in this instance. This 2026 model year failure indicates NHTSA's investigation scope should expand to include current production vehicles.
