Dome light flashing, car wont start, car will not shift out of park

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. If the vehicle has not been started, it is normal for warning lights to showing up on the instrumentation, as they will light up to show they are working. A check engine light is only showing a concern when illuminated with the engine running. The fact you have flashing lights and a no start situation plus will not shift out of park sounds like a 12 volt engine battery concern. The battery is likely not strong enough in charge to start the vehicle, and worse yet - lower than needed power is likely causing a malfunction of the anti-theft system, resulting in the lights flashing. I would recommend obtaining roadside assistance or a tow service come out and either attempt a jump start of the vehicle or have the vehicle towed to a repair shop near you to have it tested as needed. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
