    I have a new issue with my 2005 Gen 2 Prius T3. The car is unmodified.

    On starting from cold, the fuel gauge registers as empty and the main warning light (red triangle) displays along with the rest of the usual orange warning lights. This seems to clear after a few seconds and the issue does not repeat after the car has been driven for a bit - starts up normally.

    I don’t have the ability to read fault codes but wondered if this was a familiar issue to anyone?
