Important 2023 GMC model year changes include a new Yukon Denali Ultimate in standard and XL lengths, redesigned steering wheels in some models, GM’s Super Cruise is offered, and supply-chain constraints on some features. Three years of OnStar are now included on many models, but it’s invoiced to the vehicle price. Here are all the 2023 GMC Model Year Changes.
2023 GMC Acadia Changes
SLT, AT4, and Denali models get a redesigned up-market steering wheel. It is still leather-wrapped, with cruise and audio controls. Three new color options are available: Volcanic Red Tintcoat, Ultra Blue Metallic, and Sterling Metallic.
Part supply constraints affect the standard front and rear park assist, available heated steering wheel, and available vented front seats, which may not be available on some early build models.
2023 GMC Hummer EV Pickup Changes
The Hummer’s Infinity Roof is the T-Tops of the 21st century. Four removable panels turn the pickup into a virtual convertible. A new Infiniti Roof with opaque panels becomes standard sometime after the start of production. The transparent paneled Infinity Roof becomes an option.
New 22-inch wheels become standard, with 305/55R22 tires. The 305/70R18 tires become optional, part of the Extreme Off Road Package.
New standard assist steps are a late availability feature. They replace the now optional rocker protectors with integrated steps.
2023 GMC Savana Changes
The optional 2.8 diesel 4-cylinder turbo is no longer offered, leaving only the standard 4.3 V8 and 6.6 V8 gasoline engines.
2023 GMC Sierra Changes
The 3.0 Diesel in the Sierra 1500 gets a boost in horsepower of 28 and in torque of 35 pound-feet, now 305-horsepower and 495 pound-feet.
A new AT4X AEV includes a steel front bumper with incorporated recovery hooks and 275/70R18 all-terrain engines.
Front seatbelts on Double Cabs and Crew Cab HD models are now height-adjustable.
Adaptive cruise control is now optional on every Sierra 1500.
Due to supply constraints, ventilated front seats, 120-volt power outlets, wireless phone charger, front and rear park assist, steering column lock, and hood insulator pads may be deleted from some models (not Denali). When supplies are corrected dealerships may retrofit the hood insulating pads and power outlets.
2023 GMC Terrain Changes
The Terrain gets 5 additional horsepower for its 1.5-liter turbocharged 4-cylinder engine. Power brakes are now boosted electronically.
Elevation package models get a new wheel design.
Terrain Denali Black Diamond Edition includes black 19-inch wheels, a power sunroof, Surround Vision camera, Automatic Parking Assist, Adaptive Cruise Control, ventilated front seats, and heated rear seats.
2023 GMC Yukon Changes
If the Denali wasn’t luxurious enough, now there’s the Yukon Denali Ultimate. The front seats on Denali Ultimate are adjustable 16 ways and include a massaging function. The Denali Ultimate utilizes exclusive dark chrome trim, a unique front fascia, bright chrome on window trim, and unique 22-inch wheels with bright and dark chrome finishes. Exclusive interior trim includes contrasting stitching on pleated leather seats, aluminum, and open-pore wood. Stereophiles will appreciate the 18-speaker Bose system.
Otherwise, the Denali Ultimate offers standard equipment that costs extra on the standard Denali: Reverse Automatic Braking, 4-Wheel Drive, theft-deterrent alarm system, interior movement sensor, glass breakage sensor, rear-view camera washer, power-retractable running boards, panoramic sunroof, Max Trailering Package, Hitch Guidance with Hitch View camera, Trailer Side Blind Zone Alert, Air Ride Suspension, and electronic limited-slip rear differential.
GM’s Super Cruise will be offered on the Yukon, optional on Denali, standard on Denali Ultimate. This system allows hands-are driving on many U.S. highways, while a camera makes sure the driver is still focused on the road. It includes Enhanced Automatic Parking Assist that guides the Yukon Denali into a perpendicular or parallel parking space, controlling steering, brakes, and shifting.
Adaptive Cruise Control is now available on SLT.
A new wrapped steering wheel is standard.
The standard battery’s cold-cranking amps have been downgraded to 730 CCA, from 800. The diesel engine’s battery is now 850 CCA, down from 900.
Supply-chain problems may delete Adaptive Cruise Control from Denali (not Denali Ultimate). Four-way power lumbar support in driver and front passenger seats may be downgraded to two-way in SLT, AT4, and Denali (not Ultimate). Ventilated front seats may be deleted from SLT and AT4 models, with the possibility of a retrofit by dealerships later. Super Cruise may be deleted from Denali Ultimate.
Automatic Start/Stop, limited to diesel engines last year, is now standard on all engines, again.
2023 GMC model year changes include: an offering of redesigned steering wheels in some models, a new Yukon Denali Ultimate in standard and XL lengths, GM’s Super Cruise, and supply-chain constraints on some features.
