my dashboard lights take a moment to turn on

Hello, I do not anticipate that this is a charging system concern like from the alternator. But if it happened after a car wash I do worry about water intrusion somewhere important causing electrical issues. Have you ever had the windshield replaced? If so, water could be leaking in from insufficient sealing and getting into circuit control modules. Something may be related to lighting. Just a guess, but when I hear of an abnormal concern, I start thinking abnormal causes. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
