Applies if: The Toyota USA bulletin does not list this model, but its hybrid battery is also cooled with cabin air through a filter.

Clogged hybrid battery cooling fan and filterHigh-voltage battery
Engine / equipment
Hybrid battery cooled with cabin air (intake next to the rear seat): Prius, Yaris, Auris, Corolla, C-HR, RAV4, Camry and others
Period mentioned
2003 onwards
Symptoms
Hybrid battery cooling maintenance message, warning light with codes P0A80 or P0A7F, a noisy fan and less electric assistance; if ignored, the battery ages faster.
Possible cause described
Dust, pet hair or dirt block the filter and fan that cool the battery; so do objects covering the intake. Toyota USA issued bulletin T-SB-0074-20 (2003–2020 Prius and Camry, Corolla, Highlander, RAV4 and Mirai hybrids up to 2020) and recommends cleaning the filter every 5,000 miles (about 8,000 km).
Check for the garage
Clean or replace the filter and clean the fan before condemning the battery; keep the intake grille clear. At the garage, read the codes and, if needed, install the software Toyota specifies.
