2019 Subaru Legacy: won't start

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!

Subaru Starlink system constantly drains battery, leaving driver and passengers stranded. The Starlink is constantly looking for a 3G network, and my area has updated all 3G networks to 5G. After shutting car off, the Starlink will continuously search and drain battery so it will not start. The only temporary fix is to remove the fuse and disable the module. The Starlink is supposed to help in the case of an emergency, but it cannot help if the battery is dead. dealerships have acknowledged the problem but will only offer a fix for the replacement of the module for a sum of about $ 1,300.00.

Car wont start after having a new battery (only 2 months old) put volt meter on battery and reads 5.76 volts. Put 2 amp charger on it for an hour and car starts and voltage meter shows 12.26 volts after i shut it off. This is clearly an electrical problem that Subaru is trying to put off as a battery issue. This car only has 22 thousand miles on it and it is unreliable.The dealer says there is nothing wrong but anybody that knows anything about cars will disagree.

I have owned my car since January 2019. I replaced the battery in November 2022 because the car wouldn't start after being left home for a week with no one driving it. In January 2023, I had to replace my battery because the car wouldn't start after not driving it for a weekend. I was told the battery was faulty. Now, on March 1, 2023, my car won't start again since no one drove it yesterday. The fob won't even open the doors. I have heard that there is a lawsuit open over my car make, model, and year because of a battery drain problem.
