Two problems related to starter have been reported for the 2019 Subaru Crosstrek. The most recently reported issues are listed below.
Starter failed at 50 k miles left me stranded.
Our 2019 Subaru Crosstrek (16. 8k miles) is not being driven as often as it used to be because we are now working from home. On 4/4/2020 we found the original battery drained dead after only 6 days of the car being undriven. Tried and failed to start the car - dashboard lights lit up but there were rapid clicking sounds. To get it to the dealer, I started the process of jump starting it with my battery-pack type jump starter. I attached the positive cable to the positive terminal first, and the jump starter's indicator light was flashing �all good � continue�. I then attached the negative cable to the negative terminal and the indicator light turned red, which means �there is something wrong � do not proceed�. On 4/6, I brought the dead battery to the dealer using my other car. They checked the battery and because the car is still under warranty, I received a new Subaru-branded battery. I went home, installed it, and turned the car on to make sure everything worked. On 4/10, we started up the Crosstrek and took it for a several-mile trip. 6 days later, after the car not being driven, the new battery was dead - key fob would not open the car, no dashboard lights came on when we tried to start the car. Using my jump starter again, I received the same indicator light warning. We had the Crosstrek towed to the dealer on 4/16. Technicians could find nothing wrong. They charged the battery and kept the car until 4/20 when they tried to start it up � it started. We picked the car up and drove it home. Today is 4/27. The car has started up after 6 days of not being driven although last wed. And sun. I charged the battery a bit using a trickle charger. I currently do not get a warning light on my jump starter when I do a test. We are now going to drive it when we need to without using the battery charger and see what happens.
