Hi, the dash lights lighting up happens when any fault happens, and isn't necessarily an indication that there's an ECU bug. First thing I would do is check your gas cap, and then have the dealer check for any stored codes.

Also, if the fuel pump is acting up because of the neglected pump recall, that may be causing the lights.

There are two light combos that are most common, and both light multiple of those warnings, but not every light - there's more lights than what you're likely seeing. Once a system throws an error (even if it's just a loose gas cap, causing a fuel system error), then, your car turns off all assistive systems, which causes the other lights to light up.

So, short answer is "yes, multiple lights come on (no, you probably didn't see them all light up)".

Certain lights only come on for their error, such as R.DIFF TEMP, or SRS airbag system warning light, as two examples.

Here's the full list of warning and indicator lights...
