Recalls on the 2018 GMC Yukon

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

20V603000

SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUM

General Motors LLC (GM) is recalling certain 2018 Cadillac Escalade, Chevrolet Silverado 1500 and Tahoe, GMC Sierra 1500 and Yukon vehicles equipped with either a 5.3L or 6.2L V8 engine. The output of the mechanical vacuum pump can decrease over time, decreasing the amount of vacuum/power brake assist.

Risk: A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash.

19V761000

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:WHEEL SPEED SENSOR/TONE RING

General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.

Risk: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.

19V645000

SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUM

General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.

Risk: As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2020459 2,933 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 create an increase in brake pedal effort that is required to stop the vehicle. Note: This is an expansion of Transport Canada Recall 2019-324. 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 you to take your vehicle to a dealer to reprogram the electronic brake control module.

Recall 2019533 37,378 units in Canada

Brakes

Issue: On certain vehicles, there may be an error in the electronic-brake control module software. This could cause the driveline-protection system to activate when a wheel-speed sensor fails. If this happens, the brakes could apply and cause the vehicle to pull to one side. Note: This recall only affects vehicles equipped with four-wheel drive, a 5.3-L engine, and a 3.08 ratio rear axle. The problem can only occur when the vehicle is in four-wheel drive or automatic mode, and travelling at a speed between 66 and 97 km/h (41 and 60 mph). A wheel-speed sensor failure will cause the electronic stability control (ESC) and anti-lock braking system (ABS) warning lights to turn on, and a "Service StabiliTrak" message to display. Safety Risk: A vehicle that suddenly pulls to one side could increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to update the electronic-brake control module software. General Motors advises that using two-wheel-drive mode can eliminate the risk until the recall repair is completed.

Recall 2019420 5,327 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 2019324 310,121 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.

The 2018 Yukon has been at the dealership several timeswaiting for a valve body for the transmission. There are valve body recalls for other year GM vehicles with the same transmission, but not for the 2018 model even though it appears to be the same part number. I don’t understand how this 2018 model apart of the recalls when it’s got the same issues as the newer ones. This is the second Yukon I’ve bought in the last seven years and the other one had the exact same issue.

Dealership did a tune-up in June 2025 and had my truck for 2 weeks, no issues with transmission discovered or discussed. Now in September 2025, 2018 GMC Yukon has developed a torque converter shutter when driving between 40 and 50 mph. I took the vehicle to an independent shop who told me they had some computer tool to manually control the transmission, and there is an internal failure. There was a transmission flush completed hoping to gain results, however it was very short lived.

I was driving on I75 North, just North of Chattanooga. I was in the Center Lane. I lost all power to the vehicle. The engine stopped. I had no power steering, no power brakes, and was in heavy traffic. I managed to shift lanes and get it to the shoulder of the road. The vehicle was towed in. Diaganostics were completed by a certified mechanic. The engine had seized. GM has several recalls on this issue. 2018 is not included. However, this is the exact same issue that is happening with 2019 and up. That were recalled. I urge you to order an extended recall to include 2018 vehicles as well before someone gets killed.

Oklahoma City, OK

ENGINE

My 2018 GMC Yukon blew an engine with only 81,000 miles. Had four shops including (2 GM dealerships) look at the vehicle, pictures, and findings and concluded the engine had blown. The vehicle had began running very rough while driving down the road at 45mph. The CEL showed a misfire in cylinder one. The spark plug was pulled and soaked in oil. A borescope was put down the hole and found oil pooled on top of the piston. The engine has blow by the piston rings and the cylinder wall was scorn. Four shops. Four results. New engine needed. A quick google search of the engine (L83) showed multiple open class action lawsuits for this exact situation. The cause of the problem is the active fuel management system that GM created. When I contacted GM for assistance at the recommendation of the dealerships (which they have seen an increase in these engine blowing with low miles) I was informed by GM/GMC that they would look into it and could not guarantee assistance. Fast forward a couple of days I was contacted and made perfectly aware that I was 991 days outside and 21,000 miles out of warranty but they would offer “assistance” in the amount of 10% of the total cost. Four shops, four quotes for an engine replacement ranging from $14,750-$17,000 and GM was only offering $1,475-$1,700. Absolutely terrible. With multiple open class action lawsuits, stop sales, and well documented issues. I expressed disappointment and requested assistance to prevent having to seek litigation. I was told “if that’s what you want to do, you will need to talk to our legal department” and told there’s nothing they can do. Will not buy nor recommend anyone buy a GM product. They don’t respect or care for their customers.
