2019 Subaru Legacy electrical problems

Filed Mar 30, 2026 · Electrical · MA

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!

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.

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.

The Starlink screen becomes uncontrollable and begins changing screens on its own making driving very distracting and losing all control of vital functions such as radio, gps and phone. I have no control over it. I have video of the incident but cannot figure out how to upload it. I k low previous year models were recalled for the same situation and I believe there is a class action lawsuit.

Radio is delaminating and causing random calls and radio changes while driving. Serious safety issue. Subaru covered a portion of the replacement but entire cost should be covered due to it being an obvious manufacturer defect.
