Has the 2018 GMC Yukon been recalled?
3 U.S. safety recalls. Repairs are free at a franchised dealer; some are done over the air.
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.
Fix: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began November 11, 2020. Owners may contact GM customer service at 1-866-522-9559, Cadillac customer service at 1-800-458-8006 or Chevrolet customer service at 1-800-630-2438. GM's number for this recall is N202300860.
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.
Fix: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

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.
Fix: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.

Odometer Fraud. The contact owns a 2018 GMC Yukon. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 72,499.

I started my vehicle and as I accelerated I started to hear a knocking noise. The vehicle and engine have been inspected by the dealership. The problem has also been confirmed by the dealership.There were no warning lights or messages before the knocking noise started.
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.
I purchased my used GMC YUKON from a used car dealership 3/28/26. I signed the papers for the agreement while I was driving the vechicle home I lost power and it wouldn't go forward with gas applied. The check engine light came on, I pulled the suv over and it was towed. The code that popped up 0700 and 02723 both codes having to do with the transmission.

I have noticed the amount of pressure needed to apply brakes at a slow speed is a lot to where it seems like I will crash into the car or object in the way of my vehicle. I took my vehicle to a GMC dealership and was told the brake vacuum pump needs to be replaced. These vacuum pumps were already recalled by NHTSA. NHTSA #19V645000, GM #N192268490. This recall was expanded to include additional vehicles. NHTSA #20V603, GM #N202300860. I strongly believe my vehicle needs to be included in this recall. GMC repair invoice is attached.
While driving I made a right hand turn. As soon as the turn was made, the powering steering completely went out. The power steering is found to fail upon cold starts, then return to normal after operating. The vehicle has been taken to gmc numerous times with no explanation as to why or how it has happened. When asked to replace the steering rack. They stated vehicle is working as expected. It is unsafe. GMC has had recalls on the steering for many years now.
INVOLVED IN A FRONT/SIDE PASSENGER SIDE COLLISION WITH SIGNIFICANT DAMAGE AND SPEED WITH NO AIRBAG DEPLOYMENT(S).
I WAS DRIVING MY VEHICLE AND EXITING THE HW. THE REAR WHEEL OF THE DRIVER SIDE BROKE OFF AND SEPARATED FROM THE CAR WHICH CAUSED MY CAR TO HIT THE CEMENT BEERIER ON FRONT AND THE SIDE OF THE DRIVER SIDE OF THE VEHICLE. THEN THE CAR TURNED 180 DEGREES AND HIT THE BEERIER ON THE PASSENGER SIDE AND THE REAR OF THE CAR. THE AIR BAGS NEVER DEPLOYED AND WE DISCOVERED THAT THE WHEEL BROOK OFF OF THE REAR AXE. NO DAMAGE TO THE WHEEL. SEVERAL INDUSTRY EXPORTS STATED THAT THIS SHOULD NEVER HAPPEN.
