Every time we get rain and drive the vehicle it starts leaking water bad on the passenger side.This will cause water to get on your fuse panel,and have a short circuit that will cause your vehicle to drain your battery. Also car will stay running after you shut it off, then will slowly chug until the engine stalls. Also had about 2 inches of water under the carpet and mold will start to form.

I called GM and they never heard about this problem and there is no recall for this. I've seen other complaints that this can be a fire hazard. This car is nothing but a lemon. Wish we would of did more research before purchasing a used vehicle without warranty. GM needs to add this problem to there recall list. This is also common with the Arcadia's and the Traverse.

I have not did anything yet. GMC needs to fix this problem. They want me to pay $65 or more a hour to take it apart and look at it. I do not have that kind of money.

My wife and I really like our Enclave except for that horrible leaky sunroof. Interior smells musty as water literally runs down the front pillars and makes puddles onto the floor. Come on GM, sunroofs aren't a new concept.

Enclave CLX V6

  • Automatic transmission
  • 100,000 miles

Had car parked w/ right front corner slightly lower then the rest of the car. Uneven parking space. Wife had been complaining about wet floors for awhile. Massive rain storm. Found Front right foot well completely filled w/ water. Over 3" of water. Deal wanted $125 to remove headliner. I found where the drain hole and hose are. Open sunroof. locate said holes, right and left. They are located along the sunroof slide track towards the front. Pour 1/2 a cup of water into those holes. Let sit for a couple of hours till it softens dirt plugging the tube. Use a high pressure air hose, blowing directly into the hole. You will soon see all the water coming out under your car.

Every time you wash the car open the sunroof and wipe clean the "trays" that are pitched right and left to take the water to the drain hole. Road grim and other crap does get in there. 10 second job. I do this and never have the problem again.

Sunroof leaks. I've had the sunroof fixed more than once, but it still leaks. The problem has never been fixed & dealer has no idea how to fix. 1st day I brought car home I noticed the entire rear area was wet & smelled of mold. They ended up replacing all the carpet & padding, replacing some seals, but here we are 5 years later & it still leaks. Everytime we get a good rain I have to move car to cover. Rain on horizon... better think about going out today. This is a common problem with these Buicks, yet Buick hasn't recalled it. Once again, GM putting out bad product & not standing behind it.

Sunroof leaked consistently. It seeped more than leaked. Caused extensive damage to the fuse box and shorted much of the electrical system. Led to many other problems. It was never diagnosed.
