Subaru Outback electrical problems

On June 15th 2026, I was at a red light and the Auto Start-Stop feature shut off the engine. When light turned green, my car lost power and started rolling downhill. During this rolling downhill, the brakes stopped working, I was unable to engage parking brake, and I wasn't able to do anything except find a place to safely use gravity to slow the vehicle down. If the hill was steeper, this scenario could have been deadly. It was so scary, I called 911 for assistance but got lucky I was able to stop the car before there was an accident. It turns out the battery didn't have enough power to allow the vehicle to restart and if this happens when the Auto Start-Stop feature is engage you lose the ability to use the brakes. I spoke to the local dealership and acknowledge that is a problem.

SUBJECT: Formal Safety Defect Complaint: 2016 Subaru Outback – Manufacturing Nondisclosure of Latent "Day 1" Design Flaw Causing Ignition Key Entrapment, Uncommanded Steering Column Lockout, and Severe Family Safety Risk I am writing to formally report a severe, unaddressed safety defect and a deceptive corporate practice by Subaru of America, Inc. affecting my 2016 Subaru Outback. This vehicle suffers from a "Day 1" latent engineering flaw that causes the physical ignition key to become permanently trapped in the ignition cylinder, triggering an uncommanded, rigid locking of the steering column assembly. Subaru has possessed documented knowledge of this failure for years, cataloging it under Technical Service Bulletin TSB 16-112-18R. Rather than fulfilling its statutory obligation to issue a comprehensive federal safety recall, Subaru deployed a voluntary, time-bound 8-year warranty extension. Subaru conveniently did not notify me of this warranty extension. By doing so, the manufacturer unconscionably ignored this defect, placing its customers at direct peril. They capitalized on asymmetric information to shift both the financial burden and the severe physical safety risks of a known factory flaw onto my family, the moment an arbitrary time threshold expired. My family and I have been at active, continuous risk in this vehicle since the day we purchased it due to an engineering error that was present when the car rolled off the assembly line. The root cause of this failure is a fundamental engineering defect within the Continuously Variable Transmission (CVT) shifter assembly, specifically, the premature degradation of the electrical contacts within the select lever park-range switch.

Recently, the 2022 Outback my mom drives has been having some strange electrical issues. About a year-or-so ago the battery in her outback died. Not unusual in Arizona. I replaced it with an upgraded AGM (Interstate) version—same group, same cranking power. No issues. Recently, after an oil change at the dealer, she called back to report that a “Check Engine” light had come on. She was told that she probably had not put the gas cap on properly. Gas cap was on properly; light went off the next day. A few days later the Auto Stop/Start (ASS) feature started acting up (not functioning). A few days later the ASS turned the engine off and did not restart automatically—in the middle of heavy traffic during rush hour. The ASS light came on. The engine started manually, and we got it home. Battery was dead the next morning. I charged it up and took the car to the local mechanic for a quick assessment. The battery was fine, charging, but the car threw a Code: P0871 Transmission Fluid Pressure Sensor Switch. This mechanic told us that there was a Technical Service bulletin through Subaru that addressed this issue but was also aware that it could be caused by the ASS killing the battery OR other electronic modules which fail to enter sleep mode—which would also cause random lights to come on. An appointment was made to take the car into Peoria Subaru, thinking it would be something they could diagnose easily. It had previously been in for the routine oil change with the inspection. When we dropped the car off, I provided the Advisor the code and a associated TSB for the code. We got the car back that day and were told the following: The tech found that the car currently has a “Aftermarket” AGM battery. Subarus require a “Enhanced Flooded Battery” which would explain multiple codes found for loss of communications and parasitic battery drain--for systems that don't go to "sleep" when the car is not running.

I just bought my Subaru outback brand new in October 2025. I’ve maintained my oil changes at the dealership. I bought it from in the last one was last may 26. I filled up my tank with a full tank of gas June 1. On June 2 when I was driving home from work on the I 94 Highway in Detroit Michigan I was going about 50 mph when my check engine light went on and within seconds the engine failed. The car was still on, but the gas pedal wouldn’t work and I was in the far left-hand side lane of the highway. I was able to slowly pull over to the fire right hand shoulder, even though it was during peak traffic time. As I pulled over, I started seeing smoke come from under the hood. I then seen a big flame which made me quickly get out of the vehicle and then seconds two minutes later the entire vehicle was in golf in flames and had many explosions throughout. I had no prior indications notifying me that there was something wrong with my vehicle. I had no problems with it. There was only 12,500 miles on the vehicle. There was no obvious cause to this happening. It was only me in the car however if there were small children in car seats or less mobile elderly people in the car, I don’t think that they would have made it out safely. The fire department came and put out the fire. A police report was made with the Michigan State troopers. My insurance is progressing. They are working on a claim. I also contacted Subaru of America and opened up a case with them. I notified the Subaru of Troy dealership that this happened.

DRIVING ON RTE 81 SOUTH IN THE AREA OF WILKES - BARRE WHEN ALL OF THE SUDDEN MY ENTIRE DASH ELECTRICAL SYSTEM WENT COMPLETELY BLACK, NOTHINGWAS SHOWING, NO GAS, NO SPEED OMETER, DATE,TIME , BLINKERS, LANE CHANGE ETC. AND THE NAVIGATION SCREEN TURNED LIME GREE. ABOUT 30 SECONDS LATER THE LIME GREEN TURNED BLACK. I HAD NO ELECTRONICS AT ALL. I WAS IN THE MIDDLE LANE DOING 55-65 AND COULD NOT SIGNAL TO PULL OVER. ABOUT 2-3 MINUTES (FELT LIKE AN ETERNITY) WENT BY AND ALL OF A SUDDEN EVERYTHING RE-APPEARED. NOTE, THE CAR DID NOT TURN OFF. I PULLED OVER, TURNED CAR OFF, WAITED A COUPLE OF MINUTES AND STARTED THE CAR AND IT NEVER DID IT AGAIN.

Before I begin my commute, I’m greeted by a persistent message within the center infotainment display from the satellite radio service provider SirusXM. The message will not go away until manually closed out, as the exit button is farther away from the drivers reach (more accessible from the passenger side). This can lead to distracted driving, especially if you’ve already expressed no interest in the service, prior to its other attempts. It also doesn’t help that the center console is frustratingly non responsive for the first few minutes during every vehicle startup. There’s also a number displayed on the screen to call SirusXM to opt out of the messages but the attempt is useless as they will corner you into purchasing subscription. I shouldn’t have to do this for a vehicle I own and the monopoly that service presents as the only satellite provider is anti competition.

Many controls are integrated within the main infotainment screen on the 2024 Outback. Every month or so, a SiriusXM advertisement will randomly pop-up on the screen, taking up the entire screen, rendering all screen controls/buttons useless. This is a safety concern, as not only screen controls are blocked when this ad appears, but air and comfort controls are blocked until the ad pop-up is closed.

Odometer Fraud. The contact stated that he recently purchased a 2015 Subaru Outback. The vehicle was purchased through a private sale. At the time of purchase the odometer reading was 91,000. The contact stated while obtaining insurance was informed the mileage was 194,000. A Carfax report was not obtained. There was no other agency contacted.
