Q: Many warning signs via gauge cluster

Intermittent, and ultimately unexplainable, electrical glitches can and sometimes do occur. They can represent "one off" incidents and thus they don’t recur. However, it is also possible that you have an incipient, and thus real fault. One thing you, or a mechanic, can do is check to see if any codes, or freeze frame data, were saved in the engine computer. Another thing to be mindful in the type of incident you are describing if if the car’s electrical system is "weak", that is if your battery or alternator or the charging circuit have faults, you are more likely to see warning light glitches. In your circumstance, you could request a basic check engine light diagnostic during which the mechanic will download any data that was stored, run though that data for clues and also check the battery and charging system output to rule those latter possibilities out.
