Jeep had been continually attempting to redesign the Wagoneer since the mid 1990s with various proposals.^[5] In January 2011, Sergio Marchionne, CEO of Fiat S.p.A. and later Fiat Chrysler Automobiles (FCA), announced at his press conference at the North American International Auto Show in Detroit that the name "Grand Wagoneer" would be relaunched as a new SUV built on the same platform as the Jeep Cherokee and the Dodge Durango.^[6] On September 2, 2013, Chrysler announced that they would delay production until 2015 to allow the Dodge Durango to find an audience but at the same time would use the Grand Wagoneer concept as a basis for a full-size luxury SUV that would compete against the Cadillac Escalade and Lincoln Navigator, whose redesigns went on sale in 2014.^[7]

On June 9, 2015, FCA announced that it would unveil a new version of the full-sized Grand Wagoneer at its dealers' convention on August 25, 2015.^[8] In August 2015, however, FCA announced that the production of the upcoming Grand Cherokee replacement would be delayed into 2018^[9] and was scheduled to be built at Warren Truck Assembly.^[10] On October 18, 2016, Jeep released teaser photos of the Grand Wagoneer, which indicated that it would be based on the third generation Durango and introduced as a 2019 model.^[11] The plan was delayed again in March 2017.^[12]

On December 5, 2019, spy shots surfaced of FCA testing a Wagoneer using a Ram 1500 body on frame SUV.^[13] Due to the 2020 COVID-19 pandemic, FCA delayed the start of production by at least three months and was expected to debut this full-size version in early 2021 as a 2022 model.^[14][15]

On September 3, 2020, Jeep presented the Grand Wagoneer concept, which foreshadowed the next Grand Wagoneer marketed in 2021.^[16][17] The SUV is distinguished by a massive silhouette with oblong headlights and a multi-hole grille.^[18] A characteristic feature is the lack of Jeep branded markings on the body and in the passenger compartment in favor of badges with the model name.^[19] Production models of the Wagoneer were revealed on March 11, 2021.^[20] The first models were expected to ship later in the year, with general dealership availability starting October 2021.

On 3 July, 2023, the Grand Wagoneer was launched in the Middle East.^[21]

Rear-wheel drive is standard on the Wagoneer model with optional four-wheel drive available, while four-wheel drive is standard on the Grand Wagoneer. Furthermore, introduced to the selection is the Quadra-Trac full-time four-wheel-drive system.

The Wagoneer is offered in four trim levels: Series I, Series II, Carbide, and Series III. Meanwhile, the Grand Wagoneer is offered in five trim levels: Series I, Series II, Obsidian, Series III, and Series III Obsidian. All trim levels are offered with the Standard or Long Wheelbase "L."

There are two McIntosh premium audio systems available on the Wagoneer and Grand Wagoneer: a 19-speaker system with 950-watt amplifier and 10" subwoofer, and a larger 23-speaker McIntosh system with 1,375-watt amplifier and 12" subwoofer.^[22]

Both the Wagoneer and Grand Wagoneer feature several standard screens, with several more screens being available as options. These include a standard digital instrument cluster, a central touchscreen infotainment system, and an interactive front passenger touchscreen display integrated into the woodgrain on the passenger side of the dashboard and allowing the passenger to stream music wirelessly to the vehicle's audio system via Bluetooth, view the GPS navigation map, and send directions directly to the central touchscreen display. The display features a special coating that is only viewable to the passenger, as not to distract the driver while the vehicle is in motion. Several models also feature a touchscreen control panel for the rear seat climate controls, as well as a dual-screen rear seat entertainment system that allows rear seat passengers to connect their own external devices via HDMI or Bluetooth, connect to the Internet, view entertainment from Amazon, and play integrated games via the seatback-mounted displays.^[23]

At the 2022 New York International Auto Show (NYIAS), Jeep unveiled the extended-length 2023 Wagoneer L and Grand Wagoneer L, which are a foot longer than their Wagoneer and Grand Wagoneer counterparts. Trim level and feature content are expected to be the same as the Wagoneer and Grand Wagoneer, although both vehicles will feature the new 3.0-liter "Stellantis Hurricane engine" twin-turbo inline-6 (I6) gasoline engine. The standard output version of this engine, which will be used on Wagoneer L models, produces 420 horsepower (313 kW; 426 PS) and 468 lb⋅ft (635 N⋅m; 65 kg⋅m) of torque. The high-output version of the "Hurricane" engine, which will be used on Grand Wagoneer L models, will produce 510 horsepower (380 kW; 517 PS) and 500 lb⋅ft (678 N⋅m; 69 kg⋅m). of torque^{[citation needed]}.
