1 Equipment problem

Failure Date: 01/30/2026

Incident ~ 5:40 pm, geneva NY weather ~ 10 f, not snowing. Background. On or shortly after being started, the vehicle had exhibited prior incidents of extremely rapid engine acceleration not initiated by the operator. Most recently the day before. The incident: I was in the process of very slowly parking the vehicle in a narrow laneway, and positioning the vehicle behind and in line of one other, both parallel to the laneway, in a small area that had been cleared of snow, leaving the laneway open. First, I stopped the vehicle opposite of the parked vehicle's driver side door. Second, I reversed and backed up and positioned the vehicle behind that vehicle. This involved firmly stepping on the brake to stop the vehicle once well behind the parked vehicle. Third, while keeping my foot firmly pressed on the brake pedal, I moved the shift from reverse to forward. At that time, the front wheels were still fully turned to the left. Immediately on completing the shift to forward, my vehicle made a very rapid acceleration. My foot had remained firmly on the brake and had not touched the accelerator pedal. Despite my foot being firmly pressed on the brake pedal, my car surged forward, retracing the path that I had followed while backing up. I could hear the noise of the accelerated engine, and feel the fighting of the brake as the car surged uncontrolled for about four feet and then finally stopped. My foot had been fully depressed as hard as possible on the brake the entire time and did not touch the gas pedal at all. The owner of the parked vehicle observed the incident and expressed concern since the surge was dramatic, and stopped with the right corner of the front bumper of my car within a couple of inches of the left corner of the parked vehicle. The driver's car mat was in the correct position and did not interfere in any way with the operation of the vehicle. I did not inadvertently step on the accelerator. No warning lamps or messages. Cause unknown.

4 Equipment problem

Failure Date: 07/13/2021

When the car sits unused for more than several days, it goes completely dead. I have had both my mechanic and the dealer check the entire charging system ( battery, alternator, engine drive belt etc ) to no avail. Everything tests as working within given parameters and my 2015 vehicle w/ 67,000 miles is currently on it's 4th battery ! the dealer has refused to perform the two technical service bulletin(s) issued by Subaru corporate unless l pay for them, as they claim they can find no evidence to show they are needed. As a disabled retiree, I cannot depend on this, my only vehicle, to go to doctors appointments, food shopping and other normal necessary daily activities. Thank you, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

5 Equipment problem

Failure Date: 07/01/2021

Subaru installed battery installed by Subaru in September 2020 failed with out warning. There was no sign of battery weakness nor were there any warning lights or messages of any kind displayed. Car was driven, parked and when we came back car would not start. No lights were left or equipment left on. Car is at dealers now being checked. Diablo Subaru in walnut creek CA,. Fortunately since the incident occurred when the car was parked there was no danger to us or others.

6 Equipment problem

Failure Date: 06/07/2021

Can ( controller area network) is causing a parasitic draining of my battery causing me to have to jump my car regularly and I changed the battery less than a year ago. I know that I'm not the only person that has had this issue, I'm aware of the current class action lawsuit out against Subaru for this current situation. This is a very costly a serious issue that demands attention now. It's very dishonest of Subaru to tell you that nothing's wrong or offer any fix, all while taking our hard earned money. I'm very frustrated because I can't afford to continue messing with this issue nor can I simply go out and buy another vehicle. I have been left stranded both at home and aboard leaving my wife and kids not too mention myself at risk. I have taken the vehicle in and haven't had any remedy. No other failures at the time of this reporting.

7 Equipment problem

Failure Date: 04/28/2021

I have a 2015 Subaru Legacy 2. 5i engine. The problem I have is a blown fuse in the main compartment f26 (backup). I have read Subaru forum(s) and in earlier years this is same issue that I current have in my car. In the older models this was recalled and the issue was reworked at Subaru repair centers at their cost. This issue also said it could cause a over heating and possible cause a fire. Please look into this issue. Kind regards, doug whittemore 57 lexington Ave. Haverhill, MA 01835.

8 Equipment problem

Failure Date: 09/24/2020

I parked my car on a road (neighborhood) with a slight incline. I went around in front of it to look at an item for sale (smalll pink piano) in the yard. I looked at the item, then heard my car take off. I tried to run to get into it to stop it, but it was going too fast. It ended up going to the right and running into the garage of the house I was near. It hit the left hand side of the garage and continued into the garage where it was stopped by some paint cans piled up and the back of the garage. The man who lived in the house was able to squeeze into the drivers side and back it out - I drove it home (about 2 blocks). My insurance company came out and estimated the damage at about $4500, but they have not looked underneath or at the mechanics. Subaru is investigating. Pictures are too big to upload.

9 Equipment problem

Failure Date: 02/14/2020

While driving on the freeway my windshield broke for no apparent reason.

10 Equipment problem

Failure Date: 12/01/2019

I have very small chips all over the windshield.

11 Equipment problem

Failure Date: 05/16/2018

Srvd disabled at 39000 miles. Blind spot detection system failure.

12 Equipment problem

Failure Date: 02/23/2018

After turning onto my inclined, somewhat long driveway, and applying a soft braking when entering my garage, the car suddenly sped up to a high speed and crashed into the wall which had two layers of plastic storage boxes in front of it. The boxes pushed the wall into my house which pushed my dining room hutch forward causing the top part to fall back and break just about all the crystal and heirloom items inside it. The top part of the hutch is unrepairable. My car was damaged, my home is damaged, and my hutch is ruined. I am now afraid to ever park in my garage again with this vehicle. I am also afraid of this happening elsewhere where I might possible injure others or myself.

13 Equipment problem

Failure Date: 09/05/2017

In February 2017 we experienced unintended acceleration on 6 occasions. We took it to the dealer and they said that there was nothing wrong with the car. They said that we must have done something to cause the acceleration. We know that was not the case, but we continued to drive the car. It happened another time in July. The really bad incident occurred on September 5, 2017 in a parking garage. As we were exiting the parking space, the car took off on its own. This time, we hit a concrete pillar along the side of the car and grazed one parked vehicle before getting the car to stop. Also, this time, after we turned off the car and it set for approximately 10 minutes, we turned it back on and the engine continued to severely rev. Every time the unintended acceleration occurred, we were either stopped at a light, in traffic, in a parking lot, or at a gas pump or moving very slowly with our foot on the brake as one would in a parking lot when turning into or out of a space. Subaru again told us that nothing was wrong with the car and suggested that we must be two footed drivers, which we are not. We have refused to drive the car or take repossession of it. Subaru made us get the body of the car repaired before their engineers even looked at it. This was a leased car. Subaru said we had to continue to pay off the lease because there is nothing wrong with the car. We know they are wrong.

Just purchased this car (2015 Subaru Legacy premium) a month ago. Am getting water into the engine compartment from merely car washing and I assume from rain as well. This is due from the lack of proper weather stripping on both the right and left side of the hood. My dealership has been advised and I am awaiting to hear if any resolution. The following was listed on a website from another current owner: 2015 Legacy - water / snow entering top of engine bay & burning smell hi fellow 2015 Legacy owners. Has anyone else discovered this design / safety / mechanical defect yet? I live in the northeast USA; owned my 2015 Legacy for about 3 months, and have been smelling the engine burning since I purchased. At first, the dealer said the smell was caused by the rustproofing sprayed on the exhaust, however during a snow storm I discovered snow & water entering the top of my engine bay, drenching / flooding over electrical & mechanical components and causing the toxic burning smell from the burn off of deicing chemicals / salts used on road surfaces entering the engine bay due to a lack of weather stripping. My dealer inspected my car last week and confirmed the lack of installed weather stripping and water entering the engine bay as an issue. They confirmed all 2015 Legacys are designed this way. They submitted a eqmr (electronic quality monitoring report) to Subaru of America; no response yet. (the dealer sends the eqmr to Subaru when they encounter an issue that they cannot fix) I am sharing this video to alert all 2015 Legacy owners to this issue. This is a serious safety & mechanical defect. Check your engines; conduct your own water/snow tests and share results. Contact Subaru of America, your dealer and the national highway traffic safety.

21 Equipment problem

Failure Date: 03/20/2015

While traveling on the interstate at approximately 70 mph, the glass in the moonroof spontaneously shattered. There was not another vehicle near enough to cause the damage and neither my wife or I saw anything come from the front & strike the vehicle. After we stopped to check the damage, the moon roof appeared that it had been pushed upward from inside the vehicle causing it to shatter. The moon roof cover inside the vehicle was also closed when this occurred.

22 Equipment problem

Failure Date: 02/16/2015

The gas lid wouldn't open when the lever was pulled. I had to take it back to the dealer for it to get fixed.

23 Equipment problem

Failure Date: 01/07/2015

2015 Legacy 3. 6r purchased 12/18/14 two major safety issues: 1) snow / water entering engine compartment while driving and causing a burning smell inside cabin and exterior. 2) water leak inside cabin at driver foot well area. Engine burning smell: 1/7 notified dealer of burning smell which appeared to be coming from engine/under car and inside cabin while car was idling. Dealer reviewed and was unable to replicate. 2/23/15 returned to dealer again, once again unable to replicate 2/28/15 3255 miles - brought to another Subaru dealer; dealer confirmed smell in writing and cited due to "rustproof coating from factory on exhaust". 3/3/15 - driving in another snow storm, smelled burning again, parked and opened hood - discovered water / snow all over engine compartment; on top of battery and covering all electrical components; have pictures. There is evidence of water stains and rust corrosion all over engine compartment, on electrical wires and the plastic white fuse connectors are discolored. Salt stains underneath engine hood and all over engine body. Standing water underneath the batter cradle as well as snow. Seems worse on left side then right but both sides have water. Engine hood is flush with bumper - doesn't appear to be any fit issue, however the only weather strip is a small piece above the grill area and does not stretch across and over the lights. 3/3/15 contacted Subaru of America and dealer - no response - yet. ****this is a major safety mechanical concern. At no time should water ever enter the engine compartment*** 2) water leak in cabin 3/2/15 discovered water leak inside cabin - driver foot well area. Notified Subaru of american on 3/2 and dealer. Known issues documented online with Subaru crosstrek and prior Legacy model years.

25 Equipment problem

Failure Date: 12/03/2014

I have a 2015 Subaru Legacy and the srvd (blind spot & rear backup detection) system keeps malfunctioning. Happens when the vehicle is started and does not go away when driving. Took the car to the Subaru dealer and they could not solve the issue. This is a designed safety system and not working it becomes as safety issue.
