Strange series of dashboard lights

Well mysterious lights that appear often is associated with a weak 12v battery. Check to make sure that battery is charged properly. Secondly when lights go away after the car cools (overnight), it can be an indication some type of overheating happened and it went back to normal after the car cooled. So you may want to check if the inverter pump has failed again (which can happen after replacement) and the coolant system to make sure there's enough fluid in the radiator.

And of course, lastly you can check for codes that the car has stored, that will give you a better than guessing game idea of the actual problem.

 

Scan away. There are many possibilities, so codes are needed to determine anything. Fire up Techstream and report back.

If the other computer is nearby and can be easily dusted off, that's the easiest way to get the codes.

If the dust is really sticky or something, all the lights you happen to have can also blink out their codes if you use the Tc to CG jumper wire technique you can search and read about in many other posts here. Not all of the possible warning lights can do that, but all of those can.
