2026 Subaru Uncharted

Purchased and took possession of car, a brand new 2026 Subaru Uncharted electric, on May 22, 2026. On July 2, 2026 the car was completely inoperable as the 12 volt battery had died for no reason - the car had not been driven for 3 days. Took to the dealership they ran tests and said the battery was "fine". Reported to Subaru of America. On July 16, 2026 the car was inoperable as the 12 volt battery had died for no reason - the car had not been driven for 2 days. Had it jump started by another vehicle. Reported to Subaru of America. On July 29, 2026, the car was completely inoperable as the 12 volt battery had died for no reason - the car had not been driven for 2.5 days. Towed to dealership who are not finding any issues. I am terrified to now drive this car as I am concerned that this car is going to leave me stranded somewhere unsafe or even worse the battery is going to die while I'm driving it and cause a serious accident.

The uncharted and its related models (subaru solterra and trailseeker, Toyota bZ, bZ Woodland, and C-HR, and Lexus RZ) have an issue that bricks the car. It drains the 12V battery. Our car needed a jump because the Toyota app/subaru connect app and connected services kept waking the car up, draining the 12V battery and preventing it from turning on. This car appears to have a DCM issue and exceptionally bad software that causes parasitic drain on the 12V battery. It shares the same connected services, infotainment, and other software with every Toyota and Lexus model except the GR86, and the other two Subaru EVs, the Trailseeker and Solterra. We’ve taken the car to the dealer (Timmons Subaru) who told us to bring it back if it ever happens again. Their check resulted in a good health for the 12V battery, we think that was due to the car being jumped and driven.
