On the 2020-2025 Suzuki Across 2.5 PHEV, the Suzuki Across is a Toyota RAV4 PHEV rebadge and inherits Toyota PHEV 12V auxiliary battery issues — slow drain from telematics + various BCM modules can leave a 12V dead after 7-14 days parked. Toyota issued specific TSBs: T-SB-0021-20 (covers 2020 RAV4 hybrid/PHEV), TSB 0095-20 (firmware update fixing repeat drain after replacement), T-SB-0007-21 (poor DC-DC ground connection). Toyota covers these under their TSB program even though the car sold as Suzuki.

Common Symptoms

  • will not wake
  • dead 12V

How to Fix

Request a Toyota or Suzuki dealer to apply TSB 0095-20 firmware update and verify DC-DC ground connection (T-SB-0007-21). Use a 12V battery maintainer for parked stretches over 1 week. AGM 12V replacement around £200-£300 at independent. Symptoms typically appear at 10,000-30,000 miles per Toyota field data.

Typical repair cost:$0 - $350
