On Sunday, [[redacted]], I was driving my 2017 Subaru Outback 3.6R Touring after leaving the [[redacted]]. After I had merged onto [[redacted]] and immediately before the first roundabout under [[redacted]], the vehicle emitted three warning beeps, numerous dashboard warning lights illuminated, and the engine began running roughly. I was traveling approximately 31 mph when the warnings began. While attempting to reach a safe place to stop, I entered the roundabout beneath [[redacted]]. At approximately 7 mph, the...

electronic power-steering assistance stopped functioning, making the vehicle extremely difficult to steer. I was able to exit the roundabout and pull into a parking lot without a collision. I turned the vehicle off, waited approximately five minutes, and restarted it. The warning lights were no longer illuminated. Diagnostic information later reviewed by Grand Junction Subaru documented that the vehicle's electrical voltage had dropped to 8.6 volts during the incident. The dealership could not reproduce the event or conclusively identify its cause. Although the original alternator reportedly tested normal, the dealership reprogrammed the ECU/ECM, disabled the DCM, and replaced the alternator. Because the root cause remains unconfirmed, I am concerned that the sudden low-voltage condition and loss of steering assistance could recur at highway speed. Because [[redacted]] and the two-lane roundabout are very busy, I felt that my life was in danger. As I continued through the roundabout, there was a Ford Platinum 3/4 ton truck next to me. If he would not have been paying attention, I feel like there would have been a collision and possibly personal injury to myself. I'm glad that this incident happened at a lower rate of speed but I am concerned that it will happen again and maybe the next time while I'm on the highway traveling at highway speeds. It could be fatal to and others. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

If the car engine does not run for more than 4-5 days, the battery is drained completely dead and the car needs to be jump started to get the engine to run and have the alternator recharge the battery. Ongoing issue.

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...

I drive 2.5miles to work, Tuesday [[redacted]], 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 [[redacted]] 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.

This has been a constant problem with this car. The battery is dead within 3 days. Has a constant battery drain. Subaru service can't find it. Big safety problem in cold weather. Car leaves wife stranded. The problem is clearly evident on the web blogs.

My battery continues to die leaving me stranded every winter for the past several years. It is a known issue I believe with the wiring/ fuse for the trunk hatch door. Subaru only offers a new battery - so every year I replace the battery and then end up stranded somewhere again.

Battery drain kept on happening. The nth time after buying 2 batteries and getting battery recharge 2x, Subaru sent me a letter of notice of possible problems with car keeps on finding radio or gps signal thus drains the battery. Brought car to Subaru then they changed the signal unit and gave me a new battery as well.

DCM Parasitic Drain Lawsuit for 2016-2019 Subaru Battery consistently drains to where my vehicle will not start. Dealer has replaced the battery twice (2018 & 2019) I replace the battery in 2022 and will need to so it again soon. Vehicle will not start after sitting for more that 7 days. I've been stranded at night on dark roads. I just came across the link below on a Subaru Forum where others have complained about the the same issue. and this seems to be what is going on with my 2017 Subaru Outback. [[redacted]] ?

On multiple occasions, the battery has gone dead after car was garaged for over a week and car would not start. No lights were left on or doors left ajar. There is some hidden drain on the battery. Also, the battery is not charged sufficiently while idling such as when traffic is stopped for an accident or construction and the battery will die leaving the vehicle stranded. The battery has been replaced, same events continue to occur.

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.

My car consistently is dead. Probably 25% of time I go to start it, it's dead. Battery tests fine, have spent thousands in repairs with Subaru to no avail. Have replaced battery a number of times. I know this is a huge problem among other owners. No warning lights. This has been ongoing since I bought the car new in 2017 until today. I do have most of my work receipts and I know the dealership has all the records.

Vehicle is equipped with a Starlink system and this system no longer functions due to the Subaru Data Communication Module (DCM) that only has a 3G connection module system, since 3G was fazed out the Starlink doesn't function. Since the DCM is always on the car try's to connect to a cell tower that doesn't exist, the car continues to try and connect and eventually runs the battery completely dead leaving the owner stranded. I had to have the battery replaced on 9/15/23. I have contacted Subaru of America by email with no response as of this date.

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.
