2020 Subaru Crosstrek Electrical system Problems

“My car wouldn't start after stopping to visit a friend. The friend watched under the hood when I pressed the start button. He saw sparks from under the hood. I had driven over 27 miles that day before this happened. The dealer said it was because I made too many short trips. They offered to install a battery charger which I don't feel should be necessary on a brand new car.”

“I own a 2020 Subaru Crosstrek. While driving on the freeway in heavy traffic, I had to make a hard stop due to traffic ahead. When the vehicle came to a complete stop, the engine automatically shut off as part of the vehicle’s auto start-stop system. When I released the brake to proceed with traffic, the vehicle attempted to restart, but displayed a “Disabled” message and the auto start-stop system became disabled. I had to turn the vehicle completely off and restart it manually while stopped in active freeway traffic. …”

“While driving 2020 Crosstrek Hybrid, the dashboard lights suddenly flashed and then engine stalled, leaving me with no brakes and no steering. I rolled through straight through an intersection with four stop signs and I could not stop. Luckily no one was driving or walking at the time. I couldn't start car, even with a jump start. I bought a new Interstate battery with higher specs. Three days later the same thing happened, the car stalled while driving just about to park. The dashboard lights also flashed and I saw Hybrid System this time. …”

“Beginning one year after buying this used 2020 Subaru Crosstrek base trim the starter failed and battery fully died after failing to start from a stop. The engine was OFF due to the auto-stop system and failed upon lifting my foot from the brake on a slight incline, causing a constant warning beep and a starter system failure message on the dash display. Immediately after failing to start the brake pressure significantly dropped causing my car to roll into the front of the car behind it. The car was stranded in the road and required a jump start. …”

“My 2020 Subaru Crosstrek experienced a sudden loss of motive power and stalled due to a blown ignition fuse. Diagnostic code P1604 (Startability Malfunction) was stored. Inspection by Wayne Subaru (Invoice #25340) confirmed the Cylinder 3 ignition coil had shorted and physically melted. This is the exact failure mode described in Subaru Safety Recall WRE-21 (NHTSA Campaign 21V825000), which currently only covers 2018–2019 models. My vehicle experienced a thermal event and a stall despite being a 2020 model. The dealer replaced only the melted coil and did NOT update the ECM software. …”
