No silly cone, but a 3rd brake light & new gasket (to replace the perfectly new 3rd brake light & gasket).Did they silicone the 3rd brake light in? Just about every rear leak in a Dodge is a 3rd break light. Add a bead of silicone and it seals right up, hard to remove but will never leak again
Could have also been rear window seals, clogged sunroof drains, or misaligned rear doors. All relatively easy to diagnose and fix. Surprised neither dealer did anything for you.
Headliner was bone dry.
Rear window was fixed, I ordered it that way. And, with no sunroof, because I knew the risk.
Doors fit as designed. (I spent my working life building fords).
No holes in the floor, but the rear carpet was always wet.
