2016 Subaru Legacy electrical problems

Filed Jun 8, 2026 · Driver assistance, Electrical · PA

The factory touchscreen infotainment system is experiencing severe screen delamination (internal adhesive failure). This defect causes uncontrollable 'ghost touching,' where the screen registers phantom inputs. The system cycles through radio stations, changes audio sources, and changes navigation without driver input, causing an extreme, sudden driver distraction. Furthermore, the system frequently freezes and crashes, which completely disables the backup camera display. This prevents a clear view behind the vehicle and creates a severe safety hazard for pedestrians. The dealer confirmed the issue. Contacted Subaru of America and they are unwilling to assist at all with fixing the issue, leaving the customer to pay full price to replace the screen. Does not seem like a fair business practice.

Battery dies all the time. Parasitic drain from the Starlink program in the car. There is/was a lawsuit. It involves some DCW fuse or something. Ive had to prematurely replace my battery. It also seems to be affecting the radio. It switches stations randomly.

Battery continuously dies, likely due to a parasitic drain, and it is extremely hard-taking up to 15 to 20 minutes to open the car door using the the wierd key you slide out of the key fob. As a woman, it is very dangerous when my battery dies and I am in a dark parking lot and I can't even get inside the car and lock the door for safety. Been happening for years lastest time was today 02/17/2026. For some reason, the class action suit said I was not a class member for the same problem.

Car battery dies after the vehicle sits for longer periods (approximately 2 weeks or more?). Roadside assistance has tested battery twice after jumping the vehicle and stated the battery is still healthy. Various Subara owners report similar situations in online forums, and the culprit seems to be a design flaw where the DCM module is trying to connect with the obsolete 3G cellular network, causing a parasitic battery drain.

Battery dies really fast and ended up doing a replacement right after moving from Idaho to utah and losing a bolt and had to use a wrench from my late husbands toolbag in the trunk to keep it on the positive terminal I do believe after just having left the emergency room and was quite ill. The battery acid started to corrode the cables and everything along with it. Including the back seat, that had a seatbelt that got ripped accidentally when removing a babyseat from the car,

Battery has failed twice in a matter of a year. Both batteries were top of the line and no reason can be seen for failure. I see that there are a great deal of the same sort of complaints listed here and Subaru should be well aware of this issue.

I've own a 2016 Subaru Legacy Limited 3.6, for coming on 2 years. In the last 3 months I've had to replace my battery twice. The last being a red top battery costing $300+ and only lasted 2 days. The first incident that was most disruptive was, driving home in rush hour traffic when I lost all power, radio cut out, all lights on dash go out, my car begins to sputter and there is no power steering. Once traffic rolled to a stop it dies and wouldn't turn back over, couldn't pull my key from the ignition, roll the windows up, and once in park I couldn't change to neutral. It was very dangerous due to traffic, and I was stuck on a bridge that was a main arterial, with no emergency flashers. Had to have the city law enforcement call to get my car removed from the roadway. Had it towed to the dealership I purchased it from. The next day they told me my battery was dead and I needed a new one. Tested my alternator and that test good. Then again it died under the same symptoms as it did the first time. Leaving me stranded on a busy highway, at 10 at night. All of my symptoms were directly related to my a/c being on and sitting too long without driving, at idle or stop and go traffic and progrssively got to being a main battery drain. My key ittermediately wont pull from the ignition, steering wheel wont lock in place. My windows will randomly not roll up, but bounce down and stop halfway and lock temporarily in that position. I believe its all electrical problems or voltage issues. None the less... if there is no way to repair this, than it should be a recall..... because it's a serious problem with no solution and Subaru is fully aware of it.

My 2016 Subaru Legacy 4 -Door Sedan has Power Windows. When my vehicle was under it's Extended Warranty I had an issue with the Passenger Side Window. When trying to roll the window down, it would roll down and then quickly roll back up. Over and over again. I had to wait and possibly even turn off the vehicle to finally get the Passenger Window to close. But needless to say, it made me very nervous. I took my vehicle to the Subaru Dealership in Grapevine, Texas for repair. It was repaired at the time, at a cost of $100.00. But here I am yet again, and the same problem has happened again. And now my Driver's Side Window will not even roll down, at all. I no longer have the Extended Warranty, unfortunately. So, I am truly unsure if I feel comfortable taking it back for repairs. Wondering if this will happen again. And with the Driver's Side Window not being able to roll down at all, this has proved dangerous for me and my Mother. Who also drives my vehicle. It was/is especially quite dangerous going to do Curbside Pickups, Drive Thru for my Prescriptions, or food orders. I am very concerned for mine and my Mother's Safety with both Front Driver's Side and Passenger Side Windows not working properly at all. I have never had a vehicle with this kind of issue before and feel if Subaru is all about Safety then all my Windows should work properly. I am at a real loss here as to what to do, as I cannot afford any repairs due to financial hardships and my poor health. So, it is rarely driven anymore, even though I have paid the loan off and have the Title for the vehicle. I am very perplexed and need help as to what I could or should do, other than report this Safety Issue to the federal safety agency. Thankfully though, the Rear Windows work properly. I have not discovered any issues with those two windows. No Warning Lights or Alerts have been present either for the front windows. But it is a definite problem and safety issue when the front windows do not work as they should.
