    I had the same issue with my 2009... There was a seal missing from the mfg. the 2008 has a recall bc the drain tubes disconnect bc they were too short....make sure the dealer checks this out. GM took care of mine buti had to stay after them about and it took 4 visits to get it done!

    I want to add to my above post. My 2008 enclave is still under warranty (I received a three month warranty when I purchased it). The dealship said that they will no longer try to fix the leak, as I posted above. The said that they would silicone it shut and take the fuse out so no one could open it. This would also not allow me to open the moon roof shade also. The sun roof option to purchase it with the car is approximately $1600.00 and tax. I think if GM is not willing to replace the sunroof, then there should refund the money for that option and then I might let them silicone it shut. I hope this helps other people choice not to purchase GM cars, as they do not even honour their warranties.

    My 2008 Buick Enclave has started leaking from the sunroof...can't even leave it outside in the rain or the inside of my car will be soaked. Apparently it was eligible to be fixed in a recall, but the recall expired back in 2009, before I owned the car. Now the dealer says they can fix it, but GM will only contributed $145 towards the repair cost.

    I don't understand how GM can admit to faulty equipment (hence the recall), and then put an expiration date on fixing it. Does anyone have suggestions on how to escalate this with GM?

    I have a 2008 Buick enclave and it is leaking a lot from the sunroof, I have a appointment with the dealership tomorrow morning, is there any recall or GM reference about the sunroof that I should discuss with the dealer, my car is out of warranty

    Good luck - I had the same problem and had mine fixed this week. GM only paid $145 towards the $545 repair cost. I'd love to hear how it turns out for you. There was a recall, but it expired in 2009, which is ridiculous.

    I need to start out by saying we are loyal GM supporters and have been for years. So when we were in the market for a new vehicle there was no hestitation it would be a GM product. However, after the response to our problem I would hesitate a second time. I have read many messages about the sunroof leaks and I have to say that the 2009 leaks also. We had our enclave twice to the dealership and they finally found the source. The technician verbalized that it was a factory problem. The robot that sealed the moon roof and sun roof missed two areas and did not properly seal them. We keep our enclave in the garage so we did not have a problem until recently, after the warranty expired. The bill was $154. I have been dealing with GM about the bill. Even though they acknowledge that this is a factory mistake they refuse to reimburse us the money. They gave us two options. A $500 credit toward a new enclave, which we are not in the market for, or $100 dollars towards the next service needed, but it expires in one year. I asked for an explanation why they could not reimburse us since it was a factory mistake and they just kept saying the warranty expired and they were sorry. I have to say $154 may not be a lot of money to a large company like GM, but for us it is. I understand that the warranty expired, but it is still their mistake. It came from the their factory in this condition and they acknowledged liability, but still refuse to reimburse the full amount. I am very disappointed in GM and the response they have given. Does anyone have any suggestions? I thought about contacting the better business bureau...
  • Hello. I have a 2008 enclave that I bought used in 2010. I started having the leaking issues about 8 months ago, and they have escalated greatly in the past 2 months! My enclave has 98,000 miles on it and I can't imagine being able to trade it in for another vehicle. What are we supposed to do?? :cry:

    ">Symptoms: My 2009 Buick Enclave had wet floors after a rain on the passenger side. It was hard to say where the water was coming from as the water dripped a ways before exposing itself, turned out the sunroof was leaking. This could cause flood damage, mold, fill my interior fuse panel with water and/or fill plastic cover to blower motor and ruin it.

    Solution: I manually reconnected an adapter between sunroof housing and drainage tube that had become disconnected, then zip tied each end really snug (you could use a hose clamp if so inclined, but I felt zip tie would hold) then I used RTV Silicone Sealant all around it because I had a tube laying around

    Instructions on How to DIY Fix at home:
    Where is the water coming from? I used a controlled water hose to spray water on specific areas until I reproduced the problem. I saw as water filled the sunroof bowl, a drip would begin at passenger side feet area.: The sunroof has a bowl meant to collect water and drain it through a tube to below the car. This bowl has two drain holes, one drains thru a tube down driver side, the other drains down passenger side behind panel either side of front windshield. --pic shows drain hole in sunroof bowl in the corner lit by flashlight , it should be clear of debris--

    PROPER TEST: Take a bowl of water up a ladder with your moonroof full open, fill the moonroof bowl with water. If hole pictured above is not clogged water will either drain into your car or down by the tire as it should. If it does not drain, it is clogged. If anyone ever tries and use pressurized air through the drain hole they risk popping the drain tube out unless it is secured with a hose clamp.

    This job requires you to remove some interior trim to expose the adapter tube that needs reconnecting.

    I first removed interior trim to expose the tube and turns out the tube was completely disconnected. My leak was on passenger side, I had to remove the two bolts that hold the "hand grip" on panel that goes from headliner to dash. I had to use a thin flathead screwdriver to pop out the little plastic covers that give you access to the two bolts that hold the panel secure. Feel free to pop it with force as they will pop right back in later. The panel then pulls right out.

    Next, I had to remove passenger side sunshade/mirror. A regular allen wrench actually removed the three screws just fine and did not need 6 point allen wrench. --see pic of sunshade disconnected--

    Now it gets real easy, you need to pull the headliner down just enough in that corner to expose the problem. I pulled down the headliner to expose the tube and rubber green adapter that, to my amazement, was NOT connected as it should have been. No wonder, ALL water poured into sunroof was going straight into car wherever gravity led it.
    There's your problem RIGHT THERE --->

    Next is zip tie it or hose clamp it, I sealed it with silicone also for kicks. Also, I sprayed a little solution of chlorine and water to kill a little mold I saw. Then put it all back together.

    I poured water in the sunroof bowl and verified it no longer dripped in the car and was able to see the water fall as it should by the front wheel.

    Final Thoughts:
    1. I drilled two holes in the cover of my blower motor in case water ever dripped there it would not ruin it. Mine was fine, but this has been an issue for others. (see )
    2. If water had been leaking through backseat sunroof, I would just take RTV Silicone Sealant, a ladder, and then fill that whole seam with silicone from the roof. Easy fix, perfect cosmetic, only a bird landing on the roof could ever notice you had an awesome seal there.
    3. Where else could the water come from? Doubt there are too many other spots. I have heard below the front windshield and in the engine compartment, but doubt it.

    I am active duty military and my wife purchased a used 2008 Buick Enclave in 2011 while I was on deployment. I strongly encouraged her to avoid GM products, based on GM's general reputation, but she ignored my advice because she thought the Enclave was "pretty." Well, less than two years later, and with only 50,000 miles on it, our Buick is leaking like all the others on this site. We got into the vehicle yesterday evening, during a hard rain, to discover the rear lighting fixture over the 3rd row seat leaking!

    Based on what I've read on this forum, there does not appear to be a point in taking our vehicle to our local Buick dealer. I'm sure the dealer's inflated prices to repair this design flaw will exceed the price of having this repaired by a trusted mechanic; even with the rather insulting $154 credit GM appears to be offering. I'd go ahead and seal the sunroof myself; however, I'd like some assurance from a professional that there is no secondary damage or mold in the roof.

    That said, a couple of things I'd like to note if GM customer service cares about what their customer's think.

    1. My family will never again purchase a GM vehicle.

    2. My wife loved the aesthetics of her Enclave and would have been a lifetime customer; however, the lack of manufacturing and production quality control and the poor manner in which GM has responded to its customers with this issue over the lifetime of this vehicle model is unacceptable. I will not put my family or my wallet at risk by again purchasing from a company of this caliber.

    3. Luxury utility vehicles are a dime a dozen in this market. Treating your customers like you're the only game in town is simply bad business; especially when you take into consideration the marketing cost of obtaining new customers vs. repeat customers and the secondary effects to the GM/Buick brand.

    4. If there is a class action lawsuit, I will gladly join in with the rest of these folks.

    As an aside, before I returned home from my deployment, I purchased a new car for myself as well: A 2012 Volvo S60 sedan directly from the Volvo factory. Best darn purchase I've ever made; superior luxury with high reliability and an affordable price. It even has a sunroof that doesn't leak. Frankly, when comparing the overall quality and value of my two "new" cars, I'm sold on the European automakers.

    Thank you for your post. I followed it and determined that my hoses wee connected but slightly clogged. I unclogged them and made sure all connections were snug. Water still accumulated. Careful testing revealed that the forward edge of my sunroof (rubberized area) did not form a strong enough seal to keep water out. So the water collected too fast to drain properly. I teen forced that area and NO MORE LEAKS!!!!!! So happy my truck has been dry. I DID IT MYSELF!!!! Did not want to lose this battle cause it's LESS THAN 7 months of payments left! Your post gave me the confidence to search for the answer. Thanks again!!! :-))))))

    Oh yeah, my repair took about 2 hours and less than $25!!!!!!
  • jspratt1jspratt1 Posts: 4
    I reinforced the rubberized sunroof edge!!! Thanks again!!!
  • theglue99theglue99 Posts: 1
    Could you please describe how you reinforced the seal and with what materials? Thanks!
  • Excuse the delay...
    To reinforce the seal, I used items I had on hand.
    1. I prepped the rubber edge of the sunroof by cleaning it with alcohol (that air dried). I actually used extra strength started fluid.)
    2. I applied a thin layer of petroleum jelly to the Enclave body surface that will come in contact with the leading sunroof rubber edge. (This is the front and about two inches on each side.
    3. I applied a rubber sealant to the rubber edge of the sunroof. It was a uniform layer the thickness of a new pencil eraser. (I used 3M stage 2 black weatherstripping adhesive.)
    4. After watching the sealant change from shiny to dull (and slightly tacky), I closed the sunroof and let it set for a few hours.

    I tried to post pics but unable to do so. FYI: Still no more leaks!! On another note, I have also fixed other friends and family members trucks.
  • Hi I am a 2008 buick owner and my sunroof leaks also. Do you have anything in writing that there was a recall for the sunroof in 2009?
  • Hello, anyone have a DIY fix with a moonroof leak? Mine just started leaking yesterday. It is a 2008 and never had a problem until yesterday. I checked the sunroof but everything is okay there.
