Owner reports
Selected complaints filed with NHTSA by 2019 Subaru Legacy owners, lightly cleaned up (personal details are redacted by NHTSA).
Touch screen driver information system has random display and audible warnings. Audio and navigation display cannot be controlled and does random radio channels and map displays. The screen developed bubbles under the front panel that appears to activate the touch sensor for the display. This condition is very distracting to the driver and might cause unsafe vehicle operation. The display changing and beeping during driving causes an unsafe situation. It also impacts the ability to use and see the rear view camera as the display is distorted due to the delamination/bubbles. This problem was identified by many Subaru Legacy and Outback owners in 2018 which led to a recall and warranty extension for repairs. The radio/nav display is manufactured by Harmon. It was widely reported in 2019 and the problem persists. …
Infotainment system screen began bubbling. Then it started randomly selection icons by itself. Then it got to the point where it is unusable and constantly is making selections on its own. I can't even make selections if I want to. Whole screen is effected. Subaru of America is aware and my dealer first denied knowing it was an issue but later admitted to me they have gotten several complaints of the same. Dealer ordered a replacement over a year ago and I have still not gotten a replacement because they keep telling me it is back ordered and that they put a rush on it. Still nothing in over a year. This problem also causes the battery to drain while parked. I had to put a brand new battery in and it still drains. A year or so after that, Subaru sent out a notice that they will reimburse for that issue. I don't have any paperwork left from my replacement costs. …
There is a recall for this issue in Subaru vehicles through 2018 but our 2019 Legacy has the same issue. The head unit very soon after purchase (brand new from dealer) started to delaminate and not respond to touchscreen interaction. Now it is so bad that it is as if the head unit is possessed. It changes radio and settings randomly, cycles the screen, makes random phone calls if a phone is connected, changes navigation (Android Auto) on its own and suddenly it's navigating you to Mexico... Even if we aren't using the screen it is dangerously distracting because it is constantly glitching. We are out of warranty so the dealer wants us to pay for this repair on our own. We want to see the recall expanded to include 2019 and later model years. According to numerous reports online, I know we are not the only ones. …

Had to jump start the car with the original Subaru several times in 2020 and 2021, to the point that I carry a portable battery starter kit. In 2023, 1/16/23, at inspection I broke down and bought a new battery before I was aware of the recall. No problem. Come 1/1/24 I go to start my car and the battery is dead dead dead. The DiHard battery is 1 year old. I have had to jump start the car 3 times this year, and it is 1/7/24. The vehicle has 36,000 miles on it. I had the battery tested today at National Tire & Battery, where I purchased the battery on 1/16/23, and it is operating within parameters. But that's to be expected since I had driven the car there. This is not a battery issue. It has to be an electrical system issue. I have an appt. with Subaru on 1/22/24 to investigate the issue.
Unintended acceleration, on 2 occasions. First occasion, car was in DRIVE waiting at a traffic stop and the engine radically increased it's RPM from idle to over 6000 RPM, remaining there. Braking control maintained the automobile's position. Shifting the car into neutral caused RPM to increase further. The car was shut off, restarted, and seemed to function normally. On the second occasion, which occurred later the same day, the car was off and then started, and while still in PARK with my foot on the brake immediately jumped to over 6000, remaining there. Once again the car was shut off, restarted, and seemed to work normally. It was taken directly (and slowly) to the manufacturer's service center at my local Subaru dealership. They have not been able to re-create the problem as of this date.
Starting in late October 2023 I began having multiple dead batteries despite replacing the battery and having the battery tested on several occasions and it tested fine. Frustrated with the inconvenience I decided to google the problem and discovered information on the car's DCM searching for the 3G network which no longer exists. The constant search, even when the vehicle is off causes the battery to die. I am a caregiver and my clients depend on me to be at their homes when I'm scheduled to be there. They depend on me to use the bathroom, to be fed, to be kept safe, to be transported to doctors appointments and other places among other things. My regular mechanic as well as a mechanic at Anchor Subaru both confirmed the DCM was causing the battery to drain. There was no warning at all.
2019 Subaru Legacy battery drain. The car would not start, it was jumped in February 2023. In March, the car would not start and it was jumped and taken to the Subaru Serramonte dealer, a claim was filed for the extended warranty and the battery was replaced at no charge. In April 2023, the car would not start, it was jumped and taken to the dealer, the battery was replaced at no charge. In June 2023, the car would not start, it was jumped and taken to dealer where it is now not jumpable and the dealer says the electrical system is draining the battery through the On Star system. There is a 2-month back order on the part, at which time the car is not usable. The dealer claims they cannot disconnect the On Star system due to safety issue.
Due to a dead battery issue in 2025, I bought a new battery. A year later, the car wouldn't start & I finally got it jumped. Ran fine for 3 weeks, then wouldn't start again. I brought car back to the Interstate battery shop, who tested the alternator, which was fine, but he said the battery was appearing low. After researching this problem, I discovered there's a known issue that the battery dies due to a parasitic draw. Subaru knows there is a problem but refuses to correct the issues. The dealer I bought the car from neglected to tell me there was an existing issue and will be happy to charge me $500+ to diagnose. This is a major defect on Subaru's part, and all future buyers should be aware of it!
If the car is not driven every day the battery dies due to a parasitic draw. Subaru knows there is a problem with the DCM from these years but refuses to correct the issues which there are 3 that are known. Dcm constantly searches for 3g network that is no longer killing the battery, Subaru changed the recommended cold cranking amperage of the battery well after manufacture, and won't test without a new battery being installed, and they expect the consumer to pay for both the testing and battery, to meet certain epa standards they altered the function of the alternator so it doesn't charge the battery until the engine is warm and won't fully charge the battery.
