I think recall work was not done, but says it was done (or is not open). Does it say when and where recall work was done? This car has a parasitic battery drain, 3 batteries in 3 years, required 2 jump starts, 1 call to AAA. There is a recall for such an issue, but I do not believe it was fixed and done. It showed NO open recalls, and just last week I had brake work for a recall done.

Subaru was not willing to cover the cost to replace their faulty gear shifter. My key gets stuck in the ignition. This problem has been confirmed by a dealership. No warnings happen, it gets stuck. This is a safety issue because I have to leave my keys in my car (unlocked) and come back for them when the car decides to recognize that it is in park. This is a know issue and Subaru wiped its hands of me and said deal with it by yourself.

I'm the original owner, purchased May 2017, and have had to replace the battery five times. Online research indicates that the root cause is phantom draining caused by the DCM apparently searching for a no longer existent 3G signal. Subaru has not addressed the issue directly and has instead issued a technical service bulletin to AAA affiliates to advise their customers to go to dealerships for larger batteries, group 47, with higher cold cranking amps which will also require new battery trays, hold downs and an adjustment to the car's computer. My dealership in Carlsbad, CA informed me the cost might exceed $650 and would not be covered by Subaru. I strongly believe this is an issue that Subaru must address on their dime.

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.

Throttle fails to respond for a brief but serious amount of time. When pulling into traffic, instead of accelerating the engine remains at an idle and the car moves forward slowly. I push on the throttle trying to make it go. Then it takes hold and the car leaps forward. Safety: Normal power is delayed as the car moves into traffic. Oncoming traffic must slow to prevent an accident. The dealer where I purchased the car, Santa Monica, CA, tried to find error codes. Also removed the throttle valve to check that it wasn't somehow stuck. They drove the car briefly. They say they've done all they can. No warning lamps, messages, codes stored in the computer. Note that the throttle pedal signals the computer to work the engine throttle valve (so I'm told). Problem occurs about once a month. First time was when I took posession at the dealer's. I requested to recind my purchase but, because I didn't by the cancellation option ($250), they refused.

The back lift gate is closed according to the dash display, but the computer detects that the lift gate is NOT closed resulting in a battery drain. The indication that I get is when I start driving I get a beeping noise. I reset the hatch by pressing the hatch button manually. It opens and closes but when you restart the car you get a hesitation as if the battery is dead. This is the 2nd time this has happened to me in the last month and the 3rd time in the past 5 months this year. April 19th I had to jump my car because the battery was dead. I took it to a mechanic and they checked the battery and they advised the battery is fine. It happened again on May 11th, where I put something in the trunk, I closed the trunk it was closed no indication that it was not. The car drove fine. I started the car and again the battery hesitation, when I started driving I received the same beeping, I had to get out the car and manually open the hatch to reset it. The computer needs to be adjusted to detect when the lift gate is actually closed. Having the lift gate not closed but no indication for the drive is a safety problem.

11/06/23: During a routine oil change at the dealer a multipoint vehicle inspection was conducted. The inspection revealed an upper oil pan leak. The repair involved removing the engine and replacing various components (gasket, O-Rings and etc.). The vehicle was well maintained and had only 43,492 miles on it. The oil leak potentially could have caused an engine compartment fire (my opinion). Subaru paid $1,500 of the repair. A vehicle with only 43,492 should not have this type of issue. There was also a transmission leak detected that was covered by extended warranty. I was unable to upload any files on your system.

My 2017 outback having problem removing the key from the ignition when turned off and in PARK. They changed the key cylinder and this didn't resolve the issue. When I went to pick up the car after the cylinder change the technician tried to show me that the problem was resolved and the KEY WAS STUCK. $648 spent with no resolution. There is a known warranty problem with the park switch BUT they cannot replace the switch unless the technician is able to have the diagnostics connected to the car while the problem occurs. With an intermittent problem, this is very unlikely. Dealer wants me to take car home but I want the problem resolved, cannot just leave the car in ACC when unable to remove key. They will periodically check the car with car jockeys and let me know when they find problem. I have their loaner vehicle.

Vehicle has a chronic battery drain issue. I have replaced batteries repeatedly. If the vehicle sits undriven for a few days the vehicle will not start due to dead battery. It is unsafe to have a vehicle you cannot rely on to start. There is no warning when this occurs. This is happening every where for the 5th generation Subaru Outbacks, Foresters and was subject to a class action lawsuit. Subaru's response is to install a new battery, charging the customer a 'discounted' price without fixing the cause of the battery drain.

My 2017 Subaru Outback has a parasitic battery drain. The battery dies after one day of non-use. It has to be jump started. The battery is less than two years old and is the second battery since we purchased this car in 2019. Took it to a auto repair service to be checked and the technician found a parasitic draw that continually cycles between .05 mil amps to .14 mil amps. This may be the CAN system not going into sleep mode and draining the battery. This is a potentially hazardous situation and can leave me stranded in remote or dangerous locations. Subaru is well aware of this problem and yet has not addressed this problem.

I experienced 2 incidences of sudden unexpected acceleration (SUA), the second one led to an explosive collision. Subaru asked that I sign the EDR release but refused to give me (rightful owner) a copy. With significant effort I obtained a copy of the EDR for myself. It is near impossible for the consumer to obtain their rightful copy, significant because it stinks of poor transparency for Subaru to investigate Subaru (see below). Once I obtained my copy, I released the EDR to Subaru and my vehicle was inspected by SOA at our local dealership. For some untold reason, the vehicle would "not to be released to me" at the end of the day but was held for additional time at the dealership. Later Customer "Advocacy" informed me that the results of the investigation was that the throttle was active 1.5 seconds prior to impact and that it was a case of "pedal misapplication". Because I also had the data I was acutely aware of how SOA cherry picked data to match their own narrative. I know for a fact what happened considering all the data, together with the actual facts of this potentially fatal accident. I was pulling straight into the parking spot, yet the EDR MISTAKENLY "thinks" that the car is turning sharply to the right the entire time (EDR shows this and why PBS not active). The electronic sensors are being fed ERRONEOUS information. With the steering wheel 'supposedly' at full lock, the power steering pump is told to spin faster to maintain pressure. The computer tries to pick up speed for this and sends an electronic message to open the throttle. The rpms suddenly surge and the vehicle explodes forward leaving only a fraction of a second to react before impact (at which point EDR confirms brake was on). Intermittent failures in electronic sensors do in fact happen as experts know. Incredibly, SOA refused to hear me. I am concerned for the safety of other Subaru drivers as well as those in the path of a Subaru SUA incidence. Ignoring this can have fatal consequences.

ISSUE: Battery dies rather expectantly. Recently died in subzero temps here in Denver CO, on 1/30/2023. AAA was called, no issue with battery, rather there is a parasitic drain (0.46amps) occuring without any lights or visible signs of electrical on when the car is turned off. All signs lead to this being an issue with cars CPU draining the battery in a matter days.

Upon turning off my 2017 Subaru Outback Touring, the engine turned off via the push start/stop button. However, when I went to use the vehicle later the same day, the car would not start (starter would not engage). I determined that the steering wheel was NOT locked. The transmission was in Park, and I could not move the shift lever out of Park. I attempted engage the steering wheel lock by moving the steering wheel back and forth, but without success. Vehicle now totally inoperative. Vehicle is available for inspection at my residence upon request. The safety of owner and others is compromised as follows: Because of living in a semi-rural area, I rely on this vehicle to safely transport me and my family members everywhere (grocery store, doctor appointments, emergency room visits, etc.); Failure of the vehicle to operate property could expose operator and/or passengers to extremely cold weather, such as that recently experienced in December 2022. This is the second occurrence of the same malfunction. First was in July 2022. Vehicle was serviced by Subaru of Georgetown who informed me that the problem (car would not start because steering wheel lock was not engaged) was "fixed", but that they could not duplicate. No other entity, other than the dealer, has examined the vehicle. No warning lights, messages or symptoms prior to either occurrence. Driving was normal, engine shutdown appeared normal, but subsequent restarts were not possible due to the steering wheel lock not engaging (which is what the dealer informed me was the problem at the first occurrence).

My 2017 Subaru Outback will not start after sitting all night I’ve had diagnostics ran on the battery and it shows 100% charge. After charging the battery it held until the next day it was drained again. It was snowing with winds 50 mph, and I had to jump my car to start it. The faun doesn’t work when the battery is dead and that causes the theft alarm to go off once the battery is charged. Now my check surroundings before backing up sensor stays on well after shifting into Drive and beeps incessantly while driving, the back up camera also stays on while in drive. Now I have to drive 2 hours to a dealer and pay $130 in diagnostics. I feel this is the same situation thousands of Subaru owners are experiencing and why they have filed a class action law suit. Subaru should be liable for my expenses to repair this known systemic issue in a product they manufacture that is not safe, it it leaves you stranded on the side of the road in the cold. Thank you

I have had to replace the battery multiple times since purchasing the vehicle in 2017. Each time the battery was determined to be unusable by qualified service staff. Battery replacements occurred on (1) 2019-10-18 at 34,877 miles and on (2) 2022-02-24 at 67,339 miles. The first occurrence left me stranded at a hotel on a sub-freezing day.

Both occurrences were subsequently diagnosed by a reputable service shop (Les Schwab) as a battery failure and replacement was recommended. The battery failures occurred without warning from the vehicle (no lamps).
