my 2020 Toyota rav 4 hybrid isn't starting

You should have warranty coverage and towing coverage. Send it back to the dealer.

2020 RAV4 hybrid owner. Dead battery issue. Found T-SB-0095-20 dated September 30, 2020: DCM Reset and Firmware Update (LG) https://drive.google.com/file/d/1nU21MIxjotxZjpERv7QsJ1rVKtHE27JG/edit? userstoinvite=%22%22 Had car towed to dealership even though jump start by tow driver worked. Did not trust to not happen again. Sent copy of bulletin to dealer with tow. Service advisor said newer service bulletin just arrived. So we will see if works. From what I can tell from other posts, not all dealers stay updated for updates. Hope this helps
