Our 2005 SSR has a knocking noice, all lights are now off except for the wrench

Hello, the warning lights don't concern me. The knocking sound does. No one online can hear the noise and provide advice - you'll need to seek local guidance at a shop near you. Note: don't even run the vehicle until it's checked; you can cause damage just starting it. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
