BATTERY ISSUES. maybe stemming from internal components (unsure, but likely). car completely died, when lights and all settings were turned off. bought a jump starter thinking maybe i just left something on, drove around for like an hour to juice it up and power the battery. went to car today and dead again. cannot access trunk (where i put my emergency stuff) because it's completely dead. called and had to wait 3 hours for a jumpstart after subaru automated roadside assistance hung up 4 times before i even got to speak to a representative. scheduled an appt for new car battery. so no invoice or anything yet, but i spent $150 to be able to drive it (thinking it could have potentially my fault), for it to be confirmed that it was infact subarus fault.
2020 Subaru Legacy electrical complaints
Page 2 of 2: complaints 11 to 15 of 15, newest first, as owners wrote them.
The battery for the Subaru Legacy Limited will not keep a charge. As a result the battery dies and the car will not start. On four occasions the car had to be jump started. After each jump start the car was left running for up to an hour. The next day, the battery was completely discharged and starting the engine was not possible.
1. The infotainment system crashed (happens often), which caused the touchscreen in the center control stack to turn black and become unresponsive. This also caused the EyeSight safety system, adaptive cruise control (with lane keep assist), and reverse auto braking to all shut down (my dashboard lit up with warning lights and errors). 2. Not only is this an annoyance, but having all of the safety systems in my car unexpectedly shut down is extremely unsafe, especially adaptive cruise control. Other functions of my car, such as the radio and climate controls are also inaccessible when this happens. 3. A Subaru dealer has replaced the touchscreen in my vehicle to try and remedy the slowness and crashing, but it did not seem to fix anything. My car safety systems have not shut down prior to this incident, but on this day (June 6th), they did when the system crashed, which was after the replacement. After waiting weeks to get a replacement which didn't fix anything, I felt as if I needed to go elsewhere for help with this issue. 4. Only the manufacturer has inspected this issue, and I've also emailed Subaru directly after this incident, as to which I have not gotten a response yet (emailed on Monday, June 7th). 5. The warning lamps (for EyeSight, reverse auto breaking, and adaptive cruise control) all appeared on my dashboard as soon as the infotainment system crashed on June 6th. Prior to this, my vehicle had no warning lamps. They went away a few minutes after the system rebooted (all while I was driving on the highway), and system functionality returned to normal. Other Notes: This vehicle only has about 15k miles on it, and is only 1 year and 3 months old. Issues like this should not be happening. Before the replacement of the touchscreen, I had issues with it being extremely laggy and crashing, but my car's safety systems never shut down before. This is a new issue, which prompted me to report it to the federal safety agency.
Battery drain
Radio and control unit randomly restarts and freezes, affecting the radio from working, the vehicle control and driving assistance options, and the two USB ports which are the only power sources in the vehicle from working correctly. I have no audio and cannot reset the radio and cannot change vehicle control functions. When I select certain buttons it does nothing.
