2018 Subaru Legacy Reliability Report

Owners of the 2018 Subaru Legacy frequently report issues with windshield fractures occurring without any apparent impact. Complaints describe cracks developing primarily on the lower corners of the windshield, often on the driver's side, with some instances of the windshield cracking while parked or stationary. These issues commonly arise around 30,000 to 65,000 miles. Additionally, there is a report of a sunroof shattering while driving, but no crashes, fires, or loss of control are mentioned in these complaints. Potential buyers should be aware of these visibility-related issues, particularly concerning the windshield, which may require attention or repair.

Owners of the 2018 Subaru Legacy frequently report issues with the steering system, particularly at speeds above 50 mph. Complaints often describe the vehicle pulling to one side, either left or right, as if influenced by a gust of wind, even in calm conditions. This erratic behavior is noted to occur sporadically and without warning, leading to concerns about potential loss of control. One owner reports multiple replacements of steering components, such as the steering rack and sway bar links, indicating persistent issues. The mileage at which these problems are observed varies, with one vehicle experiencing issues as early as 3,000 miles. These symptoms suggest possible safety implications due to the unpredictability of steering control.

Owners of the 2018 Subaru Legacy report issues primarily related to engine performance and safety, with complaints mentioning excessive oil consumption and catalytic converter failures. One owner describes their vehicle consuming an unusual amount of oil, with the issue persisting despite multiple service visits, beginning around 18,000 miles. Another owner reports repeated catalytic converter failures, with exhaust fumes entering the cabin at mileages of 130,000 and 180,000. Safety concerns are highlighted by two incidents involving unintended acceleration, leading to crashes; one occurs when the vehicle unexpectedly accelerates while stationary, resulting in a collision with a tree and other vehicles, while another incident involves the car accelerating into another vehicle at a traffic light, causing damage but no injuries. These reports suggest potential reliability and safety concerns for prospective buyers, particularly regarding engine components and control.

Owners of the 2018 Subaru Legacy frequently report issues with the fuel system, notably inaccurate fuel gauge readings and erratic fuel level indicators. Complaints describe situations where the fuel gauge does not move appropriately after refueling or shows incorrect levels, leading to uncertainty about the actual fuel remaining. These problems often occur shortly after purchase, with one owner noting issues as early as June 2018. Another common issue is hesitation or stuttering during acceleration, particularly from a stop. While no direct safety incidents like crashes or fires are reported, the inaccurate fuel readings can lead to concerns about running out of fuel unexpectedly. Buyers considering this model should be aware of these reported issues and the potential need for repairs or ongoing monitoring of the fuel system.

Owners report multiple issues with the structure of the 2018 Subaru Legacy. A common problem is the failure of the clear coat, with deterioration occurring in less than two years despite regular detailing. Another frequently mentioned issue is rust, particularly on the door pillars, with rust perforation from the inside noted in both front doors. Additionally, some owners describe a persistent metallic rattling noise occurring between 25-45 mph, which remains unresolved after several repair attempts. While no direct safety incidents are reported, the inability to identify or repair the noise raises concerns for some owners. These issues appear within the first few years of ownership, with no specific mileage range indicated.

Owners of the 2018 Subaru Legacy report issues with vehicle speed control, including unexpected deceleration and sudden stops. Two complaints involve crashes, one where the vehicle decelerated unexpectedly, leading to a collision with a utility pole and a parked car, and another where the car came to a sudden stop on a freeway, resulting in a rear-end collision. Additionally, owners express dissatisfaction with the cruise control feature, which they report advances speed by increments of 1 or 5 mph, leading to potential driver distraction. These issues are noted without specific mileage patterns, but they highlight potential safety implications, particularly regarding sudden stops and driver distraction.

Owners of the 2018 Subaru Legacy report issues related to the service brakes, with complaints highlighting instances of unintended acceleration and brake failure. In one case, a vehicle rapidly accelerated in reverse despite the driver applying the brakes, resulting in a crash with another parked car. Another report describes a vehicle moving forward from a complete stop while the brake was pressed, with the brakes failing to respond until the emergency brake was applied. Both complaints involve situations where the brakes did not function as expected, leading to loss of vehicle control. These incidents underscore potential safety risks, particularly regarding brake responsiveness and unintended vehicle movement.
