The contact owns a 2016 Subaru Outback. The contact stated that while driving at an undisclosed speed, the low oil warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the engine seal had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 110,000.

While slowly backing out of a parking space, the vehicle suddenly accelerated on it's own - I do not recall pressing on the accelerator but the engine surged and the vehicle rapidly reversed and struck 4 other parked cars. It felt as if the accelerator became stuck and would not respond to braking. No warning light or dashboard alerts appeared. Subaru eyesight and adaptive cruise control were not engaged at the time. There was no known obstruction under the petals. This felt like a serious malfunction and could have caused serious injury. I am reporting this in case it is part of a wider issue affecting this model and because I see that there are multiple complaints to you about sudden unintended acceleration, especially during low speed maneuvers like backing out a parking space.

Arriving at my childhood home, I followed the driveway to the left to park in front of the garage door. With my foot on the brake and slowly rolling to a stop, the car suddenly accelerated and jolted forward making contact with the garage door and the frame of the garage. This caused damage to the house, garage door and the front of the car. Thankfully there was no other car in the way or a pedestrian! only the house and car were damaged. This was sudden and there was no warning or prior occurrence to make me aware of the problem. We spoke to the dealer service manager and at first he said he never heard of anything like that. After further conversation he admitted that another car had a similar issue. They kept the car for two weeks and couldn't repeat the issue. We then went on line and found there are several class action lawsuits against Subaru for the same thing - unexpected and sudden forward acceleration! but when contacting Subaru corporate for assistance in resolving this, they claimed they never heard of any class action lawsuits or problems such as this. We need help dealing with Subaru. They are playing with us.

My name is [xxx] [xxx] phone number: [xxx] my complaint is with Subaru of America, 1 Subaru drive, camden, NJ 08103 phone number: 800-782-2783 I would like the pennsylvania state attorney general’s office to become involved with the two lemons/pieces of junk my wife and I have been sold. My Subaru is a 2019 Outback and my wife’s Subaru is a 2020 forester. My ongoing problems with my 2019 Subaru Outback are as follows and in my opinion, I am driving a very unsafe car putting our lives at risk: 3 batteries prior to 80,000 miles resulting from a class action lawsuit filed against Subaru. Replacement of the ecm or engine control module. Burns a quart of oil at the price of $11. 00 per quart every 3,000 miles, that’s an engine problem. Right front axle broke and had to be replaced. After replacement of the right front axle, the right front axle seal, which is the axle replaced started to leak and I was charged to replace the axle seal due to a mechanics incompetence. I received a card from Subaru stating a windshield issue. Received another card regarding a fuel pump issue. A letter received this past week from an apparent cvt or continuously variable transmission issue. Now my radio stations jump around arbitrarily changing stations, tracks on my cd, and my hatch doesn’t open, but gets stuck shortly upon opening. This car is a lemon, a piece of junk and very unsafe. How many more problems are unknown to us and when will any of them occur while we are driving putting our lives in danger. If Subaru had any ethics character integrity or business morality they would have replaced this piece of junk. They are a horrible company to work with information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Car stalled in traffic. The engine was cranking but it would not start. Had aaa tow off the road and to my home. Car sat for 10 days waiting for a fuel pump (thought this was the problem). After sitting for 10 days the battery was totally dead! new fuel pump installed battery was jumped but could not start the car. After 2 hours on the charger the battery still did not have enough energy to turn over the engine. Car is in a certified service shop (wilhelm). Battery replaced and same starting issues with the new battery and the new battery is discharging at a very high rate even though the car is not starting. Bought the car used in 2023 so I have no knowledge of the history of the car. Service provider running factory diagnostic testing but so far no determination as to cause of the high rate of discharge. Verified that the fuel pump is fully operational. What we know is that with a fresh fully charged battery and a working fuel pump the car will not start and remain running. The engine stops and the battery drain is excessive.

Car was being driven on the highway in cruise control, when the cruise control turned off and the car began to decelerate. When the gas pedal was pressed, the rpms shot up but there was no acceleration. The car was pulled over, turned off, and we were not able to turn it on again. The car was towed to a shop, where they were able to identify the engine wasn’t working but not the root cause, and also mentioned the possibility of there being a transmission problem. We then brought it to a Subaru dealer, and they said a similar thing without being able to diagnose anything more specific. This car is 8 years old and has had routine, consistent maintenance the entire time. The surprise of an engine failure with no warning is very alarming and dangerous.

We had had no issues at all with our 2022 Subaru Outback until June 2025. Mileage at the time of the incident was approximately 52,000. We were driving one evening in June and all of a sudden the engine stopped and we could not drive it. It only produced a knocking sound when we attempted to turn the engine on. We had the car towed to the dealership and after taking the engine apart, they reported that an intake valve broke, flew and split one of the pistons causing the motor to seize up. There were no warning lamps, messages or other symptoms prior to the engine failure. Regular oil changes had been performed on the car. This issue came completely out of left field as we had previously had no engine issues.

While stopped at a yield sign waiting for traffic to clear so I may proceed with my left turn, I stepped on the accelerator pedal to make my left turn; however, my car did not go because the engine had turned off due to the auto stop feature. Once the engine restarted, I was no longer clear about proceeding with my left turn and had to apply the brakes very hard immediately to stop my vehicle. The auto engine stop is a dangerous feature that should not automatically be applied when starting the car.

?hi I had my car into the local Subaru dealership (wheeling Subaru) a few weeks ago to investigate a couple of issues that the car has been having for years (and they have never been able to find). Over the course of that investigation, they finally were able to recreate two issues that should have been covered under the warranty since it's been happening and reported to them for years (the seat memory programming button isn't working and the right sight steering wheel controller isn't working). The parts and labor for those two issues come to $545. But the much bigger issue is that they told me the engine needs to be pulled out and resealed because of cam carrier and spark plug gasket leaks, and that repair is $5,076 plus tax. When I expressed astonishment over this and asked what is going on, the service advisor explained this is a common problem with Subaru cars from this model year because of the switch from timing belts to whatever it has now. With the cvt engine I looked around online and discovered that this is a common issue with 2017 Outbacks. I thought I was making an investment that would last when I bought a brand new Subaru rather than a Ford, Honda, Toyota, Hyundai, etc because Subaru was supposed to be a car that did not have poor quality manufacturing issues like this. Given that this appears to be a common issue with the way this model and year car was manufactured, I am very upset that Subaru is not fixing this under recall but is expecting me to pay $5076 (before tax) to have what was explained to me as a manufacturing defect repaired. Since I've seen a lot of reports for other Subaru owners of this issue, I was advised to file a report with you to investigate. Thank you so much for investigating. Sincerely, [xxx] ? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Original owner of a 2016 Subaru Outback 2. 5l, took in to midas for small exhaust leak. Midas found that the exhaust pipe front bellows was cracking. They sent me a quote to repair the bellows and also a print out of service program bulletin number wuj-95r n the 2015-2016my Outback 2. 5l referring to the exhaust pipe front (epf) bellows cracking. I called to speak with Subaru's corporate recall center and they said my VIN was not part of the recall, however, my car was manufactured in 2015 and is having the exact same issues as the other 2016 Subaru Outback 2. 5l. Our safety is being put at risk as CO (carbon monoxide) is leaking into the vehicle due to the cracking in the exhaust pipe front bellows.

I drive 2. 5miles to work, Tuesday [xxx], I was turning into the parking lot and my car just cut off. I couldn't use flashers, restart it, put it in park or anything else. I called my husband to come help. I thought maybe the battery cable might have come loose. It was dead. I couldn't get out, if I let my foot off the brake it would roll backwards, going into the road and I didn't want it to hurt anyone. It started smoking from the drivers front side of engine. I called my husband back and said please hurry. It took approximately 7 minutes for him to arrive. I was on the phone about the smoke when he drove up behind me. He told me to get out of the car it's on fire. He tapped my bumper to keep my car from rolling backwards. I jumped out, called 911. He had sandbags in the back of his truck. He put them under the back tires so it couldn't roll into the traffic. A lady stopped that had a fire extinguisher and [xxx] attempted to put the fire out. It was getting quite large. We couldn't open the hood, he could only spray it in the wheel area up front. He had to get back the fire was getting big. The car then exploded. It was so loud, fire and smoke. I went into work and asked to be let off for that day. I smelled like smoke and my lungs hurt. I inhaled so much smoke. My daughter got me a breathing treatment setup to help with breathing. The fire department came and put the fire out. They were so kind. No police showed up, so we only have a fire department report. The tow truck showed up and took my car away. When we got home we notified our insurance agent. :engine failed, if I had been on a busy street I would have been hit. The car just stopped where it was. Yes our insurance adjuster said it could be looked at by anyone. :yes my safety and the ones around me were put at risk. My lungs are still suffering. :no it's not been reproduced by anyone I know of. :no, there was no indications that pointed at something being wrong.

According to my mechanic, the engine cradle is severly corroded and needs to be replaced. According to Subaru, today December 4, 2024, Subaru inspected my vehicle and determined it was badly corroded. I have pictures to show this and the report from Subaru showing they did look at this corrosion. I had wanted Subaru to replace the engine cradle because of the damage. They claimed the car was out of warranty and was 12 years old. Even so, that much corrosion should not have happened.

Vehicle stalls when stopping. This is a huge safety issue because stalling at intersections can cause accidents. Dealership diagnosed a faulty torque converter. This torque converter (it should be part number 31100ab170) issue is widely known in this production series of the Subaru Outback. After hundreds of complaints were filed with the NHTSA, Subaru extended the warranty on all their automatic transmissions to avoid a recall around 2017, but closed the extended warranty in 2022. Subaru now tries to convince their customers that these vehicles are too old for the issue to be attributable to them, despite knowing that they equipped these vehicles with defective parts.

Thermo control valve failure. Would not cover it.

The left front drive axel cracked while we were driving on an overpass connecting two highways. We didn’t hit or bump anything. The car just stopped, like the brakes were slammed on, except the brakes didn’t work. As we were on an incline, the car started rolling backwards, but fortunately the emergency brake worked. It happened so abruptly, I wasn’t able to fully pull off the road and my children in the back seat were screaming for their lives as truck after truck whizzed by rattling our car with their horns blaring missing us by inches. The police and fire trucks eventually blocked us from traffic until we could get a tow. The engine worked, but we couldn’t get into any gear. The mechanic said it must’ve been a faulty part to have gone like that. When the axel broke, it damaged the front differential and the transmission so the car isn’t very drivable. On a less dramatic note, a month earlier, both back doors stopped working on the same day!! the child locks failed and the doors couldn’t be opened. I consider this a safety hazard, so we spent $$$ to fix it. As we take good care of our car, I am very curious why it’s failing so spectacularly all at once.

Battery failures and being stranded due to parasitic loads from dcm.

Automatic auto off-on began to fail and car didn't start well. I began to disable the automatic auto on off while driving because it began to sound like it would stall out while stopped at a traffic light . Then I forgot to disable the automatic auto off on and car stalled out while stopped at a traffic light. I took it to dealer, rafferty Subaru, they couldn't find anything wrong with it. Then a few days later check engine light and other icons started flashing on dashboard. I took it to dealer, they said the gas cap was off. For the next week the automatic auto off on sounded like it would fail so I disabled it, the car didn't start normally every morning, and it began to feel like it didn't shift correctly as I accelerated or slowed down. About one day later it suddenly lurched to almost a stop while driving, check engine light was flashing, other icons on dashboard were flashing, the park brake icon started flashing. The engine continued to run but I couldn't go more than 2 mph. I put it in park and it started to smell like something was burning so I turned it off. I had to have it towed to the dealer, rafferty Subaru.

I see many many complaints about the head gasket material Subaru used was not compatible with the very fluid that is needed for the cars engine to not blow up. . . . . Coolant. Subaru knows the head gasket material is ruined by the coolant it needs but has left us consumers to deal with a very costly, devastating issue such as what I just want through and am still in the middle of a fight with dealer who sold me a car for 10995 and I had it 2 weeks. . . . Coolant blew everywhere had to fight with dealership to get them to tow it. I was yelled at, hung up on, calls not returned all while I have no car no way to work and as a [xxx] and a child to raise, I do not have options and live by a thread and paycheck to paycheck. . . . . It should not be allowed that Subaru doesn't fix that since it is a manufacturing defect that they made it incompatible with the coolant it needs.

Lower oil pan leaks oil. Started leaking oil right after warranty expired. This is a known issue for Subaru cars with the 2. 4 turbo engine. Seats ripped right after warranty expired.

In heavy traffic, we were rolling slowly along, when all of a sudden the engine began revving on its own, against the brake. I quickly moved the shifter into neutral, and the engine revved wildly without my pressing on the accelerator. We couls have easily slammed into the car in front of us had I not moved the selector to neutral.

Was just driving when I noticed my car was sounding louder than usual. Then when I stared it after running some errands it sounds like a bad engine nock. So I took it in for an oil change and they told me it was a cracked exhaust manifold. Also told me it fine to drive and shouldn’t cause further problems. Then I started to smell heavy exhaust smells inside the cab of the car. Now I have to drive it with windows down or risk passing out or dying.

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.
