Car acted like it didn't want to start, flashing lights across all dash, no engine lights came on to warn of an issue. I thought it was a bad battery

Battery, ignition, alternator all test fine, starting system has an error as per getting scanned at autozone.

I had purchased an extended warranty, but did not expect a car under 70k miles to have these issues already. Will be a hassle taking into dealer for warranty and waiting to get a fix
