Car warning lights began going off and on randomly

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! When your warning lights start acting like a Christmas tree after a visit to the shop, it's usually a sign of a bad connection or an electrical gremlin. Since it started after service, I’d first check if anything was left loose—especially ground wires or harnesses near where they were working. Another suspect might be the instrument cluster itself; sometimes, a bad solder joint can cause random light flickers. Given it’s been a couple of months, head back to the shop and have them double-check their work! If you need any further advice or want help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554!
