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.

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.

The contact owns a 2018 Subaru Legacy. The contact stated while stopped at a traffic light with her foot lightly depressing the brake pedal, the vehicle independently accelerated and crashed into the rear bumper of a vehicle stopped in front of her. The contact stated no warning light was illuminated. The contact stated that her front bumper, radiator, and part of the frame that supports the bumper had been damaged and needed to be replaced. The radiator had been damaged and leaked out all the coolant. There was only minor damage to a trailer hitch on the rear bumper on the vehicle the contact crashed into. The other vehicle was able to drive away from the scene of the crash and the contact drove her vehicle to a nearby repair shop. The police were not involved.

P014A error code. Started car and was about 1/8 mile away from home driving at 40 mph on country road, and all the lights came on the dash (check engine, eyesight off warning light, battery, oil, etc...). immediately turned around and went home. My obdii scanner said P014A error. I reset the code. Called dealer to see if it was safe to drive and drop off (30 miles away) and they said yes. They then said if they cannot read the code they cannot do anything about it (because I reset it and it is not historically saved in the car). The code happed Aug 17, 2020 has not appear again as of Sept 22, 2020. I don't know if they are related, but I have been having very strange problems with the radio volume since then. I've rotated the heat dial and it's turned the radio volume up / down, started the car and the volume is at maximum (after quickly turned the volume to zero, turned it to one is accpetable and 2 is way too loud).

While stopped at a red light as soon as the light turned green I proceeded to accelerate and heard a rattle and then a loud boom explosion sound. My torque converter, engine, and flexplate exploded causing it in operable and placed me in an unsafe location stranded on the roadway. Subaru of America has now had the car since thanksgiving this a major safety problem, I still don't have my car.

While exiting off highway, the can unexpectedly shut off nearly causing a wreck. Car would not restart. The entertainment screen remained working the entire time. The instrument cluster went black and remained this way. Automatic windows, entertainment screen, radio all worked but car would not start. A similar issue had happened two weeks ago but we were not driving... the car would not start and a master Subaru tech looked at car and they said nothing was wrong with it.. obviously they were wrong. Very disappointed in Subaru. This is a very dangerous issue.

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.
