“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 because of these incidents. Nothing was reported because no one was injured. Last year the engine was replaced with a used/refurbished one by the dealership. In less than 11 months after this engine was replaced, the dealership states I'm having multiple oil leaks again, most originating from the cam carrier. Now, my engine is struggling on slight grades. The newly installed used engine only came with a six month warranty and now Subaru states I need another engine replacement. Money is tight, so for now I'm keeping a pan under my car to catch the oil and I will keep topping off the oil every week.”
“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 vehicle. Being stuck with a car that turns off upon stopping is a dangeous situation. Subaru should be made to recall these cars and fix the issue. According to this article, it is a problem with the lock type torque converter. [XXX]”
“Coolant leak, steering power fluid leak, break pad leak, gasoline line leak, seat heater, clicking noise after turning off car, leaking seats and rear view mirror also leaking, steering wheel expanding due to possible air bag, heater and ac vents lose and also chemical smell/gas/coolant coming from front and back of car, sunroof not secured. Every wiring wet, charger port in middle compartment wet when plugging something in. Everything auto does not work. Car sounds like something is constantly leaking air or gas somewhere, even when off. My safety was at risk by having severe chemical burns on my skin everywhere, hair falling out due to exposure, almost passing out while driving due to inhaling components, low visibility due to auto dimming in rear view and side mirrors. The problem has not been confirmed due to me being in a financial bind at the moment. The car has not been inspected. due to financial problems I am not able to get the vehicle looked at. There were no warnings except for the blue temp light came on but immediately will shut back off. Car also severely vibrates when turning on. They started appearing around against of 2024”
“The contact owns a 2011 Subaru Outback. The contact stated while driving at an undisclosed speed and attempting to slow down, the vehicle inadvertently stalled. The contact was able to restart the vehicle while the vehicle was still in motion, and the vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 153,000.”
“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.”
