    To all 2007 and later Silverado and Sierra owners. I just had to bring my truck into the dealer due to the third break light assembly leaking water into the cab. It ruined the headliner and the had to pull all the interior out of it to dry up all the water. Just want people to keep a look out for this. I didn't notice it till my area got hit with some pretty heavy rain. Dealership says it doesn't happen often but they have had a couple of trucks brought in for it. The rain collects right above the the back window by the support post. I'm just letting fellow GM owners know to keep an eye out for this just in case.:neutral:
