“The 12V battery of my brand new 2026 Subaru Uncharted (under 300m) was fully drained after being parked for 2.5 days while traveling. I was unable to use my car to leave the location and needed to have a jump pack brought to the car. The car has been back at the dealer to be inspected for 19 days and counting. The battery has failed a number of times while at the dealer, with no diagnosis from Subaru and no offer to replace.”
NHTSA complaint #11754658, filed 2026-08“The contact owns a 2026 Subaru Uncharted. The contact stated that while attempting to start the vehicle, the vehicle failed to start. The contact stated that the 12-Volt battery was completely drained, even though the main high-voltage traction battery used to power the electric motor was charged. The vehicle was taken to a dealer, and a new 12-Volt battery was installed; however, two days later, the vehicle failed to start again. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 650.”
NHTSA complaint #11756999, filed 2026-08, 650 miles“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. …”
NHTSA complaint #11749958, filed 2026-07“Since 2023 starting with the Subaru Solterra and Toyota Bz4 and now in 2026 both companies have 3 models each. Toyota builds all of them for themselves and Subaru. If you do not drive these cars daily the 12 volt batteries go dead. Subaru and Toyota has continuously denied a problem and advises owners to jump it themselves or connect a battery maintainer hoping to sweep this dangerous problem under a rug. It is dangerous that can leave you stranded or if you need to go somewhere right away you can't. …”
