You probably won't see this if you have a darker colored RDX, but our white one bleeds dark lines from all the seals (mirrors, door handles, tail lights, etc.) whenever it rains or gets wet. At first, I thought maybe it was a temporary issue because the sealing material was new, but this car was built in 01/2019. It's not a big deal- it washes right off, but another regrettable oversight on Acura's part.

 

Thats pretty typical for all cars. The water needs to drain somewhere. Yes it sucks, but you just need to wipe that part again after the whole car dries.

 

Yeah this is normal. My white RDX has the same drive line and I don’t think it’s a seal thing. In the rear below the backup camera and pointy area I see black stuff accumulated here. My guess is the debris from the road (oil, dust, etc) drip down and collected here. I just wipe it off.

 

Yep, has nothing to do with "bleeding" seals.

 

Nothing is bleeding. It’s just contaminants in the air that get left as water drips down your car. My Hyundai has the same issue (it was white) and the lines were nowhere near a seal. My camper has the same issue.

 

I have found that using a leaf blower helps in minimizing left over water on the paint surface. Big help in overall drying of the vehicle.

 

Is that a leaf blower in your trunk, or are you happy to see me?
