Recall 20V60300014,620 vehicles

Problem: 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.

Recall 19V761000652,967 vehicles

Problem: 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.

Problem: 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.
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.

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 donât understand how this 2018 model apart of the recalls when itâs got the same issues as the newer ones. This is the second Yukon Iâve 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.

As of [XXX] , I witnessed a squealing sound coming from the rear end of my 2018 Denali Yukon XL truck. And it's affecting my braking. And it jerked when I changed my gears on my truck . And there are lights on in my dashboard on my truck. The engine light was blinking on and off and the traction control light was blinking on and off also. But the back driver side of the truck was squealing also. Please help me to resolve this situation. In the name of Jesus. Thanks again [XXX] and [XXX] .
