On January 14, 2013, Jeep unveiled a revised WK2 Grand Cherokee at the North American International Auto Show at Cobo Center, along with a revised 2014 Jeep Compass and Jeep Patriot.
 The new Grand Cherokee offered a 3.0 L DOHC V6 diesel engine that gets up to 30 MPG, a 3.6 L Pentastar V6 engine that gets up to 24 MPG and has 290 hp (216 kW), a 5.7 L HEMI V8 engine that gets up to 21 MPG and has 360 hp (268 kW), and the 6.4 L HEMI engine that produces 470 hp (350 kW) (SRT only).
The models are the Laredo, the Limited, the Overland, and the Overland Summit Edition model has been renamed Summit.
A new front end with a revised body-colored grille, new, smaller headlamps, and new tail lamps round out the exterior changes.
 The silver bezel on the back was removed.
 The opening rear tailgate window of previous models has been replaced with fixed glass.
There are also new seventeen, eighteen, and twenty-inch wheel and tire choices.
The SRT8 model will continue to be offered but as an "SRT" and not an "SRT8" badged model, and for the first time will offer signature details like blacked-out head and tail lamps.
 Inside, the Summit model receives the SRT's nineteen-speaker Harman/Kardon surround sound system, all Grand Cherokees receive a new steering wheel with standard paddle shifters in every model, an eight-speed TorqueFlite 8 automatic transmission, and an 8.4-inch touch screen display with Garmin navigation software, an optional CD player, and the U Connect Access System first introduced in the all-new 2013 Ram 1500.
A U Connect 5.0 touch-screen radio will also be available with an optional CD player.
The Selec-Terrain System receives multiple upgrades on four-wheel-drive Grand Cherokees.
 New exterior colors, new interior fabrics and materials, and new interior colors become available.

For 2014, "SRT8" was no longer a model of Jeep, but a separate corporate entity.
 The "8" was also dropped in the "SRT" line for this year, the Grand Cherokee being referred to as a "SRT Jeep Grand Cherokee."
 The SRT model received many new and unique features.
 For example, in the interior, it received a unique steering wheel with the SRT insignia, twenty-inch alloy wheels, performance tires, and additional SRT-only details including:
SRT-only 6.4l V8, 470 hp (350 kW)/465 lb⋅ft (630 N⋅m), propelling it from 0-60 mph in 4.5 seconds
Six piston Brembo Brakes at the front and four piston Brembo brakes at the rear
3 season tires (optional)
SRT-only performance pages in the head unit, displaying engine statistics, quarter mile/0-60, and other metrics
Nappa leather seats with SRT-only Alcantara inserts and headliner
SRT-only fascia covering hitch (if so provisioned)
SRT-only suspension modes, including track mode
SRT-only "launch" mode, designed to model world class professional driver techniques
upgraded software for transmission, with over 90 gear shift programs
