1985 Jeep Comanche problems
The Jeep Comanche (designated MJ) is a pickup truck variant of the Cherokee compact SUV (1984–1992) manufactured and marketed by Jeep for model years 1986-1992 in rear wheel (RWD) and four-wheel drive (4WD) models as well as two cargo bed lengths: six-foot (1.83 metres) and seven-foot (2.13 metres).
Introduction
During the mid-1980s, according to AMC chairman W. Paul Tippett Jr. "People are finding trucks a reasonable and sophisticated alternative to cars." To satisfy the demand and to compete with Japanese competitors, both AMC and Chrysler were preparing compact pickups for the 1986 and 1987 model years (respectively). Also at this time the financial health of AMC was poor and the automaker was in need of cash as it was preparing a new line of midsize sedans (the Eagle Premier) scheduled to be produced at a factory being built in Canada (Brampton Assembly), but the best thing the company had going for it was its popular line of Jeeps and introducing a compact Jeep pickup truck in the fall of 1985 was expected to help.
The Jeep Comanche was introduced in mid-August 1985, at a lavish event staged at the ballroom of the MGM Grand Hotel and Casino (currently Bally's Las Vegas) for AMC's over 1,500 North American dealers. American Motors included Chinese officials as part of the negotiations establishing Beijing Jeep (now Beijing Benz). The goal was to produce and sell Comanches in China through this joint venture.
The new trucks were unveiled by Jose Dedeurwaerder, an engineer and international business executive with 23 years of experience with Renault, who had just been appointed as AMC's new president. The base price of the two-wheel drive model was $7,049 (adjusted only for inflation equal to US$19,969 in 2023 dollars), making it the lowest priced Jeep model for the 1986 model year.

Common 1985 Jeep Comanche problems
The Jeep Comanche, produced from 1986 to 1992, was a compact pickup truck developed by American Motors Corporation (AMC) and later Chrysler Corporation. While the Comanche is known for its off-road ability, fuel-economy, and style, it also has some major flaws that contributed to its cancellation.
One of the most common complaints among Comanche owners is the 2.8-liter engine, which was sourced from General Motors (GM). The engine is often criticized for being underpowered and inefficient. Despite this, many vehicles with these older 2.8-liter engines have surpassed 200,000 miles, indicating that they can be reliable if properly maintained.
Another issue with the Comanche is its transmission engagement. Some units from the 1986-1992 model years may experience delayed transmission engagement, which can be caused by a faulty cooler filter. Replacing the filter with a revised version can help resolve this issue.
Electrical problems have also been reported in the Comanche, particularly in the 1986-1992 model years. These issues can range from minor inconveniences, such as a faulty radio or backup sensors, to more significant problems, such as malfunctioning dash gauges. It's important to have any electrical issues diagnosed and addressed by a mechanic to ensure the vehicle's safety and reliability.
The Comanche's sunroof has also been a source of frustration for some owners. A design flaw in the sunroof tubes of 2007 models can cause water leaks, which can damage the vehicle's electronics and seatbelts. While some owners have been able to get their dealerships to repair the leak, it may recur, requiring further attention from the manufacturer.
Finally, engine problems have been reported in the Comanche, particularly in the 2006 model year. Some units with 4.7L V8 engines have experienced engine stall, which can be caused by a faulty powertrain control module (PCM). Chrysler has recalled some of these units to reprogram the PCM and address the issue.
In summary, while the Jeep Comanche is known for its off-road ability and style, it has several common problems that can affect its reliability and safety. These issues include engine and transmission problems, electrical issues, and sunroof leaks. It's important for Comanche owners to stay on top of regular maintenance and address any issues as they arise to ensure the vehicle's longevity and reliability.
