The caps might have blown up, but it's unlikely they were the cause of the fault. Unless they're cheap knock-offs, those SP-Caps are all rated to a working voltage of at least 105C (some are 125C) and they'll survive higher than that. What they don't like is an overvoltage situation. Those specific ones are rated to 6.3V, but if something happened where the full 12V (or most if it) was across that chip and cap, it would look very similar to that.
