“Check hybrid system” warning in Toyota Prius

If your Prius throws the “Check hybrid system” warning on the dash, the majority of mechanics will surely tell you that there is a problem with the hybrid battery. And in about half of cases, they may be right. But it’s a very expensive repair, so you should try everything else that can cause this issue.

And also about the ways to solve or at least locate those reasons. If this video helped you, consider subscribing to my channel and supporting my work this way!
