NHTSA Complaint #11540127 — 2013 TOYOTA PRIUS

"Cooling Performance of the Hybrid Battery is Low" warning light turns on every 4-5 months on my 2013 Toyota Prius. Apparently, Toyota issued a bulletin to Toyota Service Departments re: Engine/Hybrid System Section Hybrid/Battery Control System Market USA. This info was never disclosed and is costly to repair every 4-5 months due to excessive buildup of dust, lint, or debris in the HV battery intake filter or cooling fan. When it first went off in June 2022 my vehicle was still under warranty up to the two additional repairs in December 2022 and May 2023 (for which the Toyota Dealership repair department didn't provide me a ticket either time but made the repair), and again now (August 2023). This is an issue that could cause the battery to fail while driving. Additionally, this issue is highly inconvenient, expensive and highly concerning. This ongoing issue affects the safety and value of my car if this issue must be repaired every 4-5 months or "every 5,000 miles). This information was never made public to Prius owners I don't believe as I never received notice. I would've sold my car sooner had i known. Here is the Toyota DOcument I received on 8.21.23 from Marina Del Rey Toyota T-SB-0062-20 dated June 18, 2020
