When owners complained
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.

Recalls on the 2018 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.
United States — NHTSA
26V289000
POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE)
General Motors, LLC (GM) is recalling certain 2026 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL vehicles with four-wheel (4WD) or all-wheel drive (AWD), and certain 2015-2020 Suburban, Escalade, Escalade ESV, Yukon, Yukon XL, and Tahoe vehicles. A component missing from the drivetrain transfer case may cause the front and/or rear wheels to lock up without warning to the driver.
Risk: Front or rear wheel lockup increases the risk of a crash.
18V673000
SEAT BELTS:REAR/OTHER
General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Risk: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 20194205,327 units in Canada
Other
Issue: This recall is for aftermarket replacement rear window glass produced by Vitro Automotriz. Certain rear window glass may not have been properly tempered. If the window breaks, the glass may separate into large pieces instead of very small ones. Note: This is a voluntary recall that is not being conducted under the requirements of the Motor Vehicle Safety Act. Safety Risk: Glass that breaks in to large pieces could create a risk of injury. Corrective Actions: The company will notify consumers by mail and instruct them to inspect the designation code marked on the rear window glass. Products affected by this recall have the designation “DOT 287” along with the lettering “VMR” (Replacement Market) and a date code that is before July 2019. This information is printed on the bottom corner of the glass. Consumers should contact Vitro's customer service at 1-412-995-6457 or argbacklites@vitro.com to arrange for replacement of the glass.
Recall 2019324310,121 units in Canada
Brakes
Issue: On certain vehicles, there could be a reduction in power brake assist due to a decrease in output from the vacuum pump. This could cause a hard brake pedal and an increase in brake pedal effort to stop the vehicle. Safety Risk: A sudden increase in brake pedal force could lead to an increase in stopping distance. This could increase the risk of a crash. Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a dealer to reprogram the electronic brake control module.
Recall 2018535780 units in Canada
Seats And Restraints
Certain vehicles may be equipped with rear seat belt retractors that do not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 208 - Occupant Protection in Frontal Impacts. The automatic-locking retractors (ALR) of the rear seat belts may not switch to a locked position when the seat belt is fully pulled out of the retractor. If used to secure a child seat, a seat belt that is not properly locked could increase the risk of injury to the child in the event of a crash. Correction: Dealers will inspect the rear seat belt retractors and replace them if necessary. Note: If the ALR is not working properly, a child seat should not be installed using the vehicle seat belt until this recall is completed.

I was involved in a traffic collision. A large vehicle turned left in front of me and I t boned that vehicle. We were traveling about 30-35 MPH at the moment of impact. My vehicle sustained major damage ($20,000+) to repair according to the body shop. My wife, daughter and myself sustained injuries. My wife and I have significant injuries. I truly believe, based on vehicle damages, and injuries that our airbags should’ve deployed. I believe it has a fault sensor that should be inspected.

On May 27, 2026 at around 7:30pm my 2018 GMC Yukon XL Denali engined failed. I was exiting E-470 southwest bound at Gartrell Road in Aurora and the engine started knocking loudly and completely quit. As I rolled to a stop I correctly suspected that the engine seized. It would not turn over, a bad odor was present, and smoke was coming from the top of the motor. It was hard to tell exactly from where because of high wind. All belts looked fine and the Castle Rock GMC dealer I had it towed to later confirmed that the engine is seized. Fortunately I was approaching the stop light and not towing anything so the safety risk from loss of power steering and power brakes was lower than normal highway driving speeds a few seconds earlier.

In addition, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light illuminated and flashed on the instrument panel. While driving to the dealer, the vehicle hesitated, while driving and the vehicle drove roughly. The dealer diagnosed the vehicle and determined that the camshaft and lifters had failed and needed to be replaced. The vehicle was not repaired due to the cost. The vehicle remained with the dealer unrepaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 131,000.

We have a 2018 Yukon with a 6.2. It has 70,000 miles on it. We have taken very good care of it and changed the mobil oil less than 5,000 mile intervals. The engine is making a terrible knocking noise. We stopped driving it the minute it started. We put it on a trailer and pulled it home and it has not been started since then. We had no warning lamps or messages to alert us of an issue. We have not had it to a dealership yet to have it inspected as we are pretty sure it is the same issue that other 6.2 engine vehicles are having. This vehicle has been well maintained. We are hoping that this year/make/model will be included in the recall for a new engine as that is what ours will be needing. It is very disheartening that you spend that much money on a brand-new vehicle, and it does not have very many miles on it and the engine fails.

SERVICE BRAKES
The vehicle is experiencing symptoms consistent with the brake vacuum pump failure described in GM Special Coverage Adjustment N182202780, which applies to full-size GM SUVs in this model range. The symptoms include a hard brake pedal upon startup, reduced brake assist, increased stopping distance, and audible vacuum or mechanical cycling noise when the vehicle powers on. This malfunction affects the vehicle’s braking performance and requires significantly increased pedal force, especially during initial operation or low-speed braking. This results in delayed braking response and reduced stopping capability, creating a safety hazard to occupants and others on the roadway. Although the symptoms match the defect described in the bulletin and the vehicle is within the published 10-year/150,000-mile coverage parameters, multiple authorized dealerships and GM corporate have refused to perform a diagnostic or repair because the VIN does not appear in their internal eligibility system. GM Customer Care case number 82474826 documents these interactions. No diagnostic evaluation has occurred because the manufacturer and dealers declined to perform one unless the VIN is pre-flagged, regardless of symptoms. No warning lights or dashboard alerts accompanied the failure. The condition began gradually and has become more noticeable over time. I am concerned that other vehicles experiencing the same defect may also be excluded from inspection or repair due to VIN list limitations, despite meeting the published program criteria.

ENGINE
1. What component or system failed or malfunctioned, and is it available for inspection upon request? The engine (6.2L L87 V8) failed completely. The engine experienced knocking and rattling noises prior to the failure and then stopped functioning altogether while driving. The engine was replaced by Village Auto in Bellmore, and the failed engine is no longer available for inspection, as it was removed and replaced during the repair process. 2. How was your safety or the safety of others put at risk? The engine failure occurred while the vehicle was in motion, creating a dangerous situation where the vehicle suddenly started shaking and could not be driven. This posed a serious safety risk to me, my passengers, and other drivers on the road due to the loss of engine power, steering, and acceleration control in traffic conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue was confirmed by an independent service center, Village Auto in Bellmore, which diagnosed the engine as irreparably damaged and requiring a full replacement. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle was not inspected by General Motors, police, or insurance representatives. Insurance would not cover this issue and General Motors failed to take responsibility for a fault in the engine. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No - all happened at once - engine light and complete failure
