Purchased vehicle in new condition in 2018. From there on forward, I've experienced problems with the radio system not wanting to work. There was no sound output. We thought it had to do with the radio satellite itself, but overtime the real issue was uncovered. After only 6 months with a brand new battery, my vehicle would not start. I'd later learn the battery depleted prematurely, and all the dealer auto shop would recommend is buying a new battery. The radio worked just fine after each time I've purchased and replaced my car battery. Now having replaced the battery twice for $197 each time, I've learned this is only a band aid fix that would last 6-12 months. I have saved my receipts but did not attach those as they contain personal info.
Tl the contact owns a 2018 Subaru Outback. The contact stated that after driving to the store and parking the vehicle, upon return, the vehicle failed to restart. The contact's husband jump started the vehicle and the vehicle was restarted and driven to the residence. The contact stated that the failure later recurred. The vehicle was not taken to an independent mechanic nor an authorized dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 16,660.
02/26/2021: car wouldn't start after being stationary. Had to get assistance to have battery jumpstarted so I could get home. 03/01/2021- car wouldn't start in driveway. Roadside assistance contacted and they were unable to get battery to charge. Husband purchased a jump box and got the car to start. He drove it to local Subaru agency and battery was tested and they said it was fine. Dealership replaced battery was replaced as it was under warranty from original battery being replaced in 12/2019. There have been other electrical issues with this vehicle prior to this date (12/2019 and 02/03/2020).
We have had repeated issues with the car dying, the battery being totally dead, and being stranded because of it. In may 2018, 3 months after we bought the brand new car, the car's engine would not turn over and had to be towed to the dealer. It was there for awhile, and ultimately we were told it was a bad battery, and they replaced the fuse box. There was no diagnosis for what occurred. Then in July 2019 at 23,000 miles, the car continued to hesitate to start. The dealer tested the battery, it failed, and it was replaced, again. On January 19, 2021, at 45,000 miles, the car would not start and we were stranded in a parking lot. The lights and radio were on but the car's engine would not turn over. Again, the dealer said the battery was the cause and replaced it. When I inquired how likely would it be that we got a bad battery this many times, we were told it happens frequently. Again, we were told there was no way to diagnose why the battery continues to fail. There must be something else going on with the vehicle; this is absolutely unacceptable. At other points in time, the vehicle's entertainment system would not work, would not turn on or off, and carplay would not be recognized. This has occurred intermittently and has never been diagnosed. We are aware from internet research that we are not the only ones experiencing this issue, as it seems owners of 2017-2020 Outbacks and Subarus have had these same issues, and have been told it is a bad battery each time.
Battery consistently drains and car will not start. Battery is new, replaced in 2020. Car has been parked for less than 12 hours when it will not start. Car has been jumped, taken to dealer who state "nothing is wrong with it", then within 1-4 days usually happens again. Has happened multiple times since 10/03/2020.
We were getting ready to leave to the store and got in the car and tried turning it on and when we inserted our keys and tried turning on the car-the car would not start and all we could hear was a clicking clacking sound coming from inside the hood. We tried starting the car again and we encountered there's the same issue, the vehicle would not start at all. We went in our other vehicle straight to the dealership to let them know that our car of 2 years would not start at all and they informed us it might be a battery issue and that we should call roadside assistance for further help. We asked if our battery was under warranty and they said they didn't know it all depended on the mileage and we informed them that our car was a brand new 2018 model with under 21,000 miles. They again said if it was a battery issue best bet was to replace with them and that it would be for a fee of $200 or more.
Car would not start, clicking noises came from the fuse panel located inside vehicle to the left of the steering wheel which we never had heard before, no prior indication of low voltage or battery discharge. Eventually red battery icon displayed briefly on instrument panel. Unable to start, had to get a tow, jump unsuccessful. Fortunately car wasparked at home in the garage. Lights were not left on nor were doors or liftgate ajar.
Battery had to be replaced within a year of owning the car as it would not start and could not be recharged. Since replacement I have had a few times when the car wouldn't start again.
8" navigation/display frozen. No back-up camera when in reverse. Does not respond to inputs either on the display or from steering wheel. "power" switch did not power down the unit. Stopping the engine and restarting did not reset the unit. Stopping the engine, open and close the drivers door and restarting did not reset the unit. Remained inoperative during morning commute (30 min). Center console remained on after exiting and locking the car. After 9 hours the battery was drained and the engine would not start. After a jump-start, the unit did reset and seems to be working normally. There should be a way to power-down (reboot) the navigation/radio display without having to stop the car and restart the engine.
