The GMC Yukon full-size SUV is once again available with the four-way power lumbar seat adjustment, GM Authority has learned.
According to GM Authority sources, the constraint on the four-way power lumbar seat adjustment feature for the GMC Yukon and GMC Yukon XL was lifted as of the start of January, 2023 production. The GMC Yukon is produced at the GM Arlington plant in Texas. Notably, the 2023 Chevy Tahoe and 2023 Chevy Suburban are once again available with four-way power lumbar seat adjustment as well.
The constraint previously affected 2022 GMC Yukon SLT, AT4, and Denali trim levels from November 1st, 2021 production onward, as well as the 2023 GMC Yukon SLT, AT4, and Denali trim levels from the start of production.
Notably, the GMC Yukon SLE does not offer the four-way power lumbar seat adjustment feature. Meanwhile, the new-for-2023 GMC Yukon Denali Ultimate was not affected by the constraint.
The GMC Yukon SLT, AT4, and Denali trim levels normally include four-way power lumbar seat adjustment as standard equipment. However, while the most-recent constraint was in place, the feature was replaced with two-way power lumbar adjustment.
Four-way power lumbar seat adjustment is one of several features no longer under constraint for the GMC Yukon. Per previous GM Authority coverage, the 2023 GMC Yukon is now once again available with the GM Super Cruise semi-autonomous drive system, the Brembo Performance Brake Kit, and wireless device charging.
As a reminder, the latest fifth-generation GMC Yukon offers three engine options, including the naturally aspirated 5.3L V8 L84 gasoline engine, the naturally aspirated 6.2L V8 L87 gasoline engine, and finally, the 3.0L I6 LM2 turbodiesel Duramax engine. Under the body panels, the GMC Yukon rides on the GM T1 platform.
Looking ahead, the upcoming 2024 model year will introduce a full model refresh for the GMC Yukon nameplate. GM Authority sources report that the start of regular production (SORP) for the 2024 GMC Yukon will begin in November of the 2023 calendar year.
