    Hello so two days ago I was driving and heard a kabeem and then a red triangle and car with exclamation mark showed up after saying problem and then my car died battery rapidly dropped as well and then all dash lights came on pulled off and it recharged while sitting but only made it a mile each time it was recharged. Battery rapidly dies while car is moving and check engine light came on as well as vsc and and everything else. Trying to find out what could be the cause. Just replaced my serpentine belt had an oil change and lucas oil sealant was used. Car was fine til the kaboom. Not overheating or nothing. 12v battery has been in the yellow when testing but not red but it was during the second snowstorm in tennessee

    you likely ran over something on the road. take it to a dealer/mechanic/muffler shop, etc. where they can put it on a lift and examine the underneath.

    Just a guess but I think you might have had one of the modules in your HV battery pack fail ("explode"). You need to have ALL the computers on the car checked for codes using a Toyota campatible scan tool. Then you can figure out your next step. (many cheaper scantools or diagnostic devices can only "talk" to one or a few of the computers on the car- that's not good enough on a Prius).

    Yea, one of the HV battery modules "exploded" would be my bet, especially given the immediate-onset HV battery "Yo-Yo" behavior.

    Any issues with the engine starting and stopping?

    Also all those dash lights store error codes that will offer more details on the problem.
