1986 Jeep Laredo 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 1986 Jeep Laredo problems
The 1986 Jeep Laredo, a part of the second generation of Jeep Cherokees, is known for several common problems that affect its reliability and performance. These issues are based on complaints from owners of this car and are detailed below.
- Oil Leaks: Oil leaks are another common problem with the 1986 Jeep Laredo. The valve cover gasket, located underneath the valve cover, tends to fail, causing oil to seep near the corners of the valve cover. Additionally, the oil pan gasket may also fail, leading to oil leakage underneath the vehicle.
- Transmission Range Selector Switch Failure: The transmission range selector switch, which is located on the passenger side of the transmission with a wiring harness that goes up and over the transmission, can also fail in the 1986 Jeep Laredo. This failure can lead to problems with reverse lights and the check engine light displaying the code P0705. If the switch is defective, it should be replaced.
- Exhaust Manifold Leaks: The exhaust manifold can crack, especially at its welding points, leading to a ticking noise while driving, especially when accelerating. Replacing the exhaust manifold can fix this issue.
- Ignition System Issues: The ignition system in the 1986 Jeep Laredo can also cause problems. The distributor wires may fail, and the wire boots on the ignition coils can deteriorate. If the vehicle has a distributor, replacing the wires and the plug, cap, and rotor is recommended. If the vehicle has ignition coils, replacing the spark plugs at the same time is suggested.
These common problems with the 1986 Jeep Laredo can significantly impact its reliability and performance. Addressing these issues promptly can help maintain the vehicle's longevity and ensure a safer driving experience.
