The referenced vehicle is a 2026 Toyota CH-R electric vehicl, purchased new on April 30th, 2026 from an authorized Toyota dealership.  On June 24th, 2026.  I tried to start the car at around 5:30am that was parked at my home, the car failed to start, after several attempts, the car became totally unresponsive to any button or my remote.  It appears the battery was extremely low or dead. I ended up called towing services.  The tow truck driver came, used a portable car battery jumper and able to start the car, put the car into neutral gear and tow to the Toyota dealership for investigation.  The next day, Toyota dealership called me back and informed me they have completed all the checks and the vehicle is not performing within specification, no issues or fixes were performed, and they said the 12V battery was fine after 2.5 hours of charging.  The dealership was unable to reproduce the issue. There was no previous warning of any kind prior to this issue happen.  I believe this vehicle may be too frequently transmitting data when the vehicle is OFF, and causing its 12V battery to drain quickly in some cases, which in term causing the vehicle unable to start.  Especially if and when the car is parked in poor cellular reception area, the car may constantly try and try to connect and transmit data, and causing rapid discharge of its 12V battery when the car is in OFF position.  This can be a safety and reliability issue if not properly addressed.  It could caused someone to be stuck somewhere, if in extreme weather conditions, it could be life threatening to someone if their vehicle is unable to start due to this issue.  In less than two months of ownership, this has already happened.  Based on person research on the internet, here are other owner of the same Toyota CH-R and another similar vehicle of Toyota BZ, also reported similar issue. I have also contacted Toyota brand engagement center and filed a case for this issue.  Requesting NHTSA's attention on this matter.
