1 Other Fuel System problem

Failure Date: 10/20/2025

My wife experienced an unintended acceleration in her 2018 Subaru Legacy. My wife had begun to slowly back out of a parking space in a school parking lot when her 2018 Legacy went into an unintended rapid acceleration in reverse. The car took off in reverse and did not respond to her applying the brakes. Somehow she managed to steer the car which was rapidly acceleration in reverse, virtually uncontrollable, and guide the car down a row of parked cars until she clipped the front of another car at the end of the row and her car came to a stop. Thank god there were no students in the parking lot at the time! the floor mats in our Legacy are Subaru mats that lie flat and in no way would affect the accelerator pedal. As the car was accelerating in reverse, and she had removed her foot from the accelerator onto the brake, the brakes did not slow the car. There is considerable damage to the right rear of the car and trunk. After the accident, when the car was restarted, the accelerator and brakes worked fine and she was able to drive it home from the scene. Thank god students were not in the parking lot!

2 Other Fuel System problem

Failure Date: 10/01/2023

I have a 2018 Subaru Legacy 2. 5. The front catalytic converter failed April 2022 with 130k miles. The part was replace by Subaru and the part has failed again. Oct 2023 with 180k miles. Exhaust fumes enter the passenger compartment (which are carbon monoxide). The same part has failed two times in a short period of time. Subaru states this is not a warranty issue . This must become a recall.

3 Other Fuel System problem

Failure Date: 08/08/2023

A friend was trying to move the car from the street when it suddenly lurched and accelerated and hit a tree, and boulder, and another car. They had not stepped on the accelerator yet. She lost control of the car. It was totaled as per state farm.

4 Other Fuel System problem

Failure Date: 09/22/2020

Acceleration hesitates or stutters when slowly accelerating, like from a stop in a neighborhood. 2018 Legacy 3. 6r has done this since purchased in April 2019.

5 Other Fuel System problem

Failure Date: 01/03/2019

Fuel level not properly indicated Subaru"s letter indicated they did not know when or if there would be a fix to the problem.

6 Other Fuel System problem

Failure Date: 12/03/2018

On the dashboard showed that the remain mileage was 70, but it stopped all the sudden due to no gas. I almost caused an accident because the car stopped on a public street with heavy traffic. After many times trying to start the car, it did not work; it was completely dead. I had to leave the car stranded to go and get gas to the nearest gas station.
