1986 Toyota 4runner problems
The Toyota 4Runner is an SUV manufactured by the Japanese automaker Toyota and marketed globally since 1984, across five generations. In Japan, it was marketed as the Toyota Hilux Surf (Japanese: トヨタ・ハイラックスサーフ, Hepburn: Toyota Hairakkususāfu) and was withdrawn from the market in 2009. The original 4Runner was a compact SUV and little more than a Toyota Hilux pickup truck with a fiberglass shell over the bed, but the model has since undergone significant independent development into a cross between a compact and a mid-size SUV. All 4Runners have been built in Japan at Toyota's plant in Tahara, Aichi, or at the Hino Motors (a Toyota subsidiary) plant in Hamura.
The name "4Runner" was created by copywriter Robert Nathan with the Saatchi & Saatchi advertising company as a play on the term "forerunner". The agency held contests to invent new names for Toyota's forthcoming vehicles. According to Toyota, the "4" described the vehicle's 4-wheel drive system while "Runner" was a reference to its all-terrain capabilities and how it could "run" off-road.
For some markets, the Hilux Surf was replaced in 2005 by the similar Fortuner, which is based on the Hilux platform.
As of 2021, the 4Runner is marketed in the Bahamas, Bolivia, Canada, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Panama, Peru, the United States and Venezuela. Many markets that did not receive the 4Runner, such as Europe and the Middle East, instead received the similarly designed Land Cruiser Prado, another SUV that shared many of the same components.
The 4Runner came in at number five in a 2019 study by iSeeCars.com ranking the longest-lasting vehicles in the US. The 4Runner had 3.9 percent of vehicles over 200,000 miles (320,000 km), according to the study.

Common 1986 Toyota 4runner problems
The Toyota 4Runner, first introduced in 1984, has built a reputation for reliability and durability. However, like any vehicle, it has its fair share of issues. The 1986 Toyota 4Runner, being part of the first generation, shares common problems with other vehicles of the same era. These issues include leaks, rust, suspension sagging, and other age-related problems.
One of the most common problems reported by owners of the 1986 Toyota 4Runner is related to the power steering system.
Another issue that affects the 1986 4Runner is related to the ECU (Engine Control Unit). Members of the Toyota 4Runner forum have reported issues with the ECU, specifically in relation to cold start injectors.
The 1986 4Runner, like other first-generation models, may also suffer from sagging suspension due to Toyota's failure to upgrade the rear springs when converting the Pickup to a Highlander.
While the 2.4L I4 engine in the 1986 4Runner is considered reliable, the same cannot be said for the 3.0L V6 engine, which was notorious for head gasket leaks.

Is the 4Runner engine good?
The Toyota's 4.0-liter engine might be reliable, but it also reliably consumes fuel at an alarming rate.
