1991 Jeep Grand cherokee problems
The Jeep Grand Cherokee is a range of mid-size SUVs produced by the American manufacturer Jeep. At its introduction, while most SUVs were still manufactured with body-on-frame construction, the Grand Cherokee has used a unibody chassis from the start.
Development
The Grand Cherokee's origins date back to 1983 when American Motors Corporation (AMC) was designing a successor to the Jeep Cherokee. Three outside (non-AMC) designers—Larry Shinoda, Alain Clenet, and Giorgetto Giugiaro—were also under contract with AMC to create and build a clay model of the Cherokee XJ replacement, then known as the "XJC" project. However, the basic design for the Cherokee's replacement was well under way by AMC's in-house designers and the 1989 Jeep Concept 1 show car foretold the basic design.
As AMC began the development of the next Jeep in 1985, management created a business process that is now known as product lifecycle management (PLM). According to François Castaing, Vice President for Product Engineering and Development, the smallest U.S. automaker was looking for a way to speed up its product development process to compete better against its larger competitors. The XJC's development was aided by computer-aided design (CAD) software systems making the engineers more productive. Meanwhile, new communication systems allowed potential conflicts to be resolved faster, thus reducing costly engineering changes, because all drawings and documents were in a central database. The system was so effective that after Chrysler purchased AMC in 1987, it expanded the system throughout its enterprise, thus connecting everyone involved in designing and building products.
The Grand Cherokee thus became the first Chrysler-badged Jeep product. Development work for the new Jeep model continued and Chrysler's employees (after the 1987 buyout of AMC) were eager for a late-1980s release date; however, CEO Lee Iacocca was pushing for redesigned Chrysler minivans, thus delaying the Grand Cherokee's release until late 1992 as an Explorer competitor. Unlike the Explorer, the Grand Cherokee utilized monocoque (unibody) construction, whereas the Explorer was a derivative of the Ranger pickup with a separate body-on-frame. A Dodge-branded version was designed as a precaution should Jeep dealers struggle to handle so many Grand Cherokee units.
The Grand Cherokee debuted in grand fashion at the 1992 North American International Auto Show in Detroit, Michigan. The vehicle that was driven was a Poppy Red Clear Coat 1993 Grand Cherokee ZJ Laredo with a quartz cloth interior and high-back bucket seats. Then Chrysler president Robert Lutz drove Detroit mayor, Coleman Young, from the Jefferson North Assembly Plant on North Jefferson Avenue via a police escort to Cobo Hall, up the steps of Cobo Hall and through a plate glass window to show off the new vehicle. Sales of the 1993 model year Grand Cherokee began in April 1992.
Production of the Grand Cherokee started shortly afterward in the purpose-built Jefferson North Assembly in Detroit, Michigan. European Grand Cherokees are manufactured in Austria by Magna Steyr. The Grand Cherokee "played a significant part in reviving Chrysler's fortunes by moving it into the then-nascent market for high-margin sports utility vehicles."
Upon its introduction, it was the first full-scale manufacture of an automobile in the US using HFC-134a refrigerant in place of HCFC-12 for the HVAC system.

Common 1991 Jeep Grand cherokee problems
The Jeep Grand Cherokee 1991 is known to have several common problems based on complaints from owners. These issues include erratic electronic shifting, a stalling engine, alternator failure, and ignition switch malfunction.
- Stalling Engine: The 2019 Jeep Grand Cherokee's engine may suddenly shut down while the vehicle is in motion, putting drivers at risk of causing a serious collision. This issue is likely linked to the Cherokee's defective 9-speed transmission, which can cause hard shifting, lurching, and wiring harness defects, leading to engine stall or a sudden shift to neutral.
- Alternator Failure: The alternator is responsible for charging the battery and providing power to electrical systems when the engine is running. When the alternator fails, the battery can drain quickly, leaving the driver stranded. This issue has affected various model years of the Jeep Grand Cherokee.
