The 2023 GMC Yukon represents the third model year of the fifth generation of Big Red’s full-size SUV. Today, GM Authority has learned that the SUV’s illuminated door sills are currently unavailable to order.
Sources close to the matter tell GM Authority that the Illuminated front and rear door sill plates, LPO (RPO code S0M) are no longer available on either the 2023 Yukon or 2023 Yukon XL. As an LPO option, this feature was typically installed at the dealership. This option was usually offered on SLT, AT4, Denali and Denali Ultimate trim levels. Notably, it was never offered on the SLE trim.
As a reminder, the 2023 GMC Yukon is notable for receiving the range-topping Denali Ultimate trim level. This uber-luxurious variant features unique Vader Chrome exterior trim, polished chrome window and door panel trim, as well as exclusive 22-inch seven-spoke ultra-bright machined wheels with bright chrome accents and dark paint.
The interior also receives a special treatment, with an Alpine Umber full-grain leather upholstery in the first, second and third rows, 16-way power front seats with massaging functionality, Denali Ultimate-exclusive contrast stitching, aluminum trim decor, genuine Paldao woodgrain trim and an 18-speaker Bose Premium Series audio system with stainless steel door and headrest speaker grilles.
The 2023 model is also notable for receiving the Brembo performance brake kit, as GM Authority covered previously.
In regard to powertrain, the 2023 Yukon is offered with 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 finally, the 3.0L I6 LM2 turbodiesel Duramax engine, rated at 277 horsepower and 460 pound-feet of torque.
