general problems of the 2009 Subaru Outback

Car stalling at stops. Received a report on all work done on this car stating issues with catalytic converter and that Subaru repaired before I bought the car. I also had loss of all brakes when the lines leaked out November 2022 . I had brakes repaired cost of $1000. So far since buying this car I have not been able to drive the car because of the stalling issues.

Car intermittently stalls and is hard to restart. Happens randomly with no check engine light or code in the ecu. Has happened on the highway at interstate speed and while stopped. Will not restart immediately. Rough idle at restart then back to normal. Mechanic was unable to recreate the problem and thus unable to repair. Creates potentially dangerous situation when stalling on the highway, intersection, etc.

While driving the engine suddenly died. Luckily we were on a lightly traveled road and were able to pull off to the side. The engine would start, run for about one second, then die. While waiting on a tow truck, a gearhead-type friend that I had called to take my wife home arrived, thought about the problem a bit, and unplugged the maf sensor. The engine ran great. It turned out that a defective air filter had allowed debris to clog the sensor. My complaint is that an invalid reading from a non-critical sensor should not be allowed to pull the engine fuel/air/timing parameters so far off that the engine will not run. Obviously the engine computer knows approximately what those values should be since it ran great with the sensor disconnected. Sensor readings beyond what would reasonably be expected should be ignored. We were lucky that we were on a country road when this occurred. Had we been in the middle lane of a busy freeway, or darting across four lanes of busy traffic, this could have been a disaster.

Car turns over but will not start.
