What owners wrote

“2nd Battery in two years is dying while car is off. 1st battery did the same, and the dealership replaced it under warranty. There is a parasitic drain somewhere, that bleeds the battery while not in use. Every start is sluggish, and if a week goes by without driving the battery is totally dead. All user related electronic possibilities have been accounted for, i.e. cabin lights, trunk latch, etc”

“The battery is constantly dying and the car needs to be jumped often. The battery has been replaced and the connections have been cleaned multiple times. The battery can still be completely drained even if it is started every day.”

“Excessive battery drain/replacement. I have had to replace the car's battery five times since purchasing the vehicle new in 2017. The newest replacement battery has lasted 3 months. The vehicle was brought to Subaru dealership at least on two occasions to evaluate/diagnose the problem and Subaru was unable to detect any problem with the electrical system/battery.”

“The battery had died multiple times and we replaced it only to continue to have the problem. Dealer service says that we must be leaving the lights on or that we need to run the car more to recharge the battery. Being stranded in upstate NY with a dead battery in winter is a safety problem.”
