The 2023 Chevy Tahoe and 2023 Chevy Suburban drop in as the third model year for each nameplate’s respective generation, with the Tahoe currently in its fifth generation, and the Suburban currently in its twelfth generation. Now, GM Authority has learned that a constraint on the SUVs’ four-way power lumbar seat adjustment feature has been lifted.
According to GM Authority sources, the constraint on the four-way power lumbar seat adjustment feature for the 2023 Chevy Tahoe and 2023 Chevy Suburban was lifted starting with January production. The constraint was previously in effect for 2022-model-year vehicles from November 1st, 2021 production and onwards, as well as 2023-model-year vehicles from the start of production.
Normally, the feature is included as standard for Premier and High Country trim levels on both nameplates. However, while the recent constraint was in place, this feature was replaced with two-way power lumbar adjustment.
The latest 2023 model year introduces only a few updates and changes over the preceding 2022 model year for both full-size SUVs. Among the updates is the addition of the new Advanced Technology Package (RPO code PDN), which is available for Premier and High Country trim levels and includes features like the GM Super Cruise semi-autonomous driver assist system, Enhanced Automatic Parking Assist, and Reverse Automatic Braking, among others. The 2023 Chevy Tahoe and 2023 Chevy Suburban are also among the first vehicles to receive the updated Super Cruise coverage, which expands the system’s availability to more than 400,000 miles of North American roads.
As a reminder, the 2023 Chevy Tahoe and 2023 Chevy Suburban offer three powertrain options, including the naturally aspirated 5.3L V8 L84 gasoline engine, rated at 355 horsepower and 383 pound-feet of torque, the naturally aspirated 6.2L V8 L87 gasoline engine, rated at 420 horsepower and 460 pound-feet of torque, and the 3.0L I6 LM2 turbodiesel Duramax, rated at 277 horsepower and 460 pound-feet of torque.
