Crankcase (pcv) problems of the 2020 Subaru Forester

Vehicle entered limp mode at highway speed (approximately 70 mph) on [xxx] freeway in washington state, it felt like I had rear ended a vehicle it shut down so hard. This was due to mis diagnosed inspection and service repair from a local Subaru dealer. Vehicle lost power rapidly, creating a dangerous safety situation. Root cause traced to tcv/pcv system defects previously documented by authorized Subaru dealers. Previous Subaru authorized dealer replaced a torn pcv hose but did not diagnose the problem causing the tear. The dash warning lights were still illuminated after the diagnostic and repair when vehicle was picked up after service. I have attached a more detailed overview of the dangerous situation. The car finally lost power on the freeway while I was in the fast lane pushing 70 miles an hour. I was in the fast lane and with no power I had to cut across both lanes of traffic and get to the shoulder. I was 45 minutes from my home and it was dark, raining and the Subaru would not start. I called a mobile mechanic I found online who came out to the freeway, roadside, where I was stranded. He worked on the car for a couple of hours in the rain. He got the car to start but it would not stay running. I had the car towed to a friend's house in vancouver, wa about 6 miles from where it had broken down. The same mobile mechanic came out and changed out one of the oil actuators and cleaned and replaced two of the ocvs then flushed the oil system and put new oil in the car. Cleared all the codes. The car starts, idles and will drive up to about 1500 rpm’s but any more than 1500 rpm’s and it dies. It's in limp mode and will move past those rpm’s. The warning lights and the pcv house splitting must have been signs of something else being wrong. That is the discussion I had with wilsonville Subaru. They diagnosed the vehicle and let me know the pcv hose was the problem. Car was towed to [xxx] in vancouver, wa sitting since April 15th, 2026 information redacted pursuant to the freedom of in.
