Engine & coolingCrash

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...

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.

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 (Bulletin Number: 16-90-13R; Revised: 02/15/18) that addresses a similar issue, but fails to mention the vehicle engine dying and the inherent safety issues that comes with the engine shutting off.

The car got overheated on 8/20/2022, because of the mechanical and design issue, specifically the coolant pipe and hose connection which got disconnected and blew up with force ejecting hot coolant liquid. The incident almost killed my husband. The hot liquid burned his abdomen and my face. He got transported by an ambulance, got admitted to a hospital, and got a 2nd-degree burner. This entire incident endangered my entire family members while we were far from home on a road trip adventure. My kids are under 10,...

and they were worried and crying. The incident definitely was reproducible, because, within a 3 hours window, the hose got disconnected 4 times, where the 4th time it hit my husband and me. A Yosemite Park Ranger was helping us inspect the car on the 3rd and 4th failure. For our safety, we have not been driving the car since 8/21/2022. So, the vehicle has not been inspected by the manufacturer.

The manufacturer, Subaru, admitted they have an issue with the ECU setting false error codes (P0128) when they issued a TSB, # 11-102-11R, calling for a software upgrade to fix the problem. This is an emissions related issue, in that it turns on various warning lights, including the SES light, making the car impossible to pass the routine smog check. So why should I, the owner, be required to pay the dealer to update the software for a problem Subaru has admittedly identified as a manufacturer error?

My 2011 Outback had a head gasket failure at 98,000 miles. The car overheated which forced me to pull over in heavy traffic. There was no prior warning or symptoms until the engine temperature warning light appeared. The car was repaired by the dealership at a hefty price. They said this problem is common on these vehicles, though no recall has been issued on the part. I filed a complaint with the manufacturer.

Durning hard/quick stops the car will shake just before stopping as if the engine wants to stall. More then half of the time the car will stall. It will start right back up but this is a huge safety issue having your call stall in the middle of the road. Subaru has issued a service bulletin 16-90-13r for this issue. Basically they need to replace the torque converter. They also extended the power train warranty to 100,000mi from 60,000mi. Cars that are outside the extended warranty are out of luck for any no...

Engine stalling. When stopping at red light, engine shut down a few times. Once I lost all electricity and maneuverability of the car. I also had ignition problems. The car won't start sometimes. I brought to dealership 4-5x and my car spent a month at dealer. They cannot find the cause. I read this could be due to cvt transmission. I bought my car from a subaru dealer two and a half years ago and only drove 7k miles. Current mileage is 95k. Subaru extended warranty of my model to 10 years for transmission. But so...
