anyone else experienced this? its only rained a couple of times, plus i had this happen when i washed the car at the weekend. When i open the rear hatch, a fairish volume of water came pouring out from below the rear window seal on the drivers (RH) side only. my car is parked nose up on a sloping drive but its sat square left to right so i'm not sure why this is only coming out of the one side. it looks like water is being captured and is only released when the hatch is opened. it runs out over the rear light harmlessly enough but i'm worried for long term damage. i need to take a closer look to see if there's a channel blocked on that side but i wondered if anyone else has seen this?
