    Purchased my 2011 Subaru Outback 3.6R Limited from the dealership, new. Since 2013, the Subaru dealer has discovered multiple oil leaks, replaced the head gaskets 3 times, thermostat 4 times, the alternator 3 times, timing belt 4 times, radiator 3 times, starter once, and my HVAC system twice...all due to my engine seizing multiple times while driving on freeways. No warning lights, just the engine seizing suddenly. This caused a few minor bumper accidents on the freeways…

    Took my vehicle in for oil change and was notified the cam carrier is leaking. Researching this issue online it seems this is a very common problem with this vehicle and if I had known earlier wouldn’t have purchased for my daughter. With such a common problem I wonder why a recall hasn’t been made?

    When I came to a stop at a light, the car stalled and the engine turned off. It was just as if I was driving a manual transmission and didn't put the clutch down while in gear. I spoke with my husband about the issue and he told me it has been happening for several months now. I have researched it a but snd found that Subaru is aware of the issue and has not offered any recall for the issue but offered an extended warranty. This is not helpful when you are the 2nd owner of a…

    in 2023 my car started overheating. took it in and it was the headgasket. even with the age of my car, it only had just over 105,000 miles on it. looking at other subarus for sale out of curiosity, I saw that quite a lot had their engines replaced. even newer than mine. i do see this as a expensive problem, which I know first hand. the headgasket went while i was on the freeway. tried to make it home, wasn't to far away, but had to be towed.

    Vehicle engine/transmission/torque converter dies when coming to a stop. This is especially an issue when having to stop suddenly and get going again quickly as the vehicle has to be put in neutral, restarted, and put back in drive. It is a safety issue at traffic lights, traffic signals, and in stop and go traffic that has resulted in a multitude of near-miss rear end collisions that put my life and my families lives in danger. There is a service bulletin from Subaru…
