Buick Enclave Leaks When It Rains



  • DO NOT BUY THE CAR! I just traded mine in after have so many problems it wasn't even funny! I posted on this thread a while back. I will NEVER own another Buick! I love my new Honda and even with all the features it has, I enjoy the no leaks THE MOST!
  • My 2008 Enclave is having the same leaky sunroof problem that has been well-documented on this and many other forums. There was indeed a recall in 2008 BUT my VIN number was excluded from the recall. Now I am having the exact same problem and the dealer wants $1900 to fix it. I want to know why my Enclave - and MANY others - are having the exact same problem that the recall was supposed to address but was excluded from the recall notice.

    If the dealership does not find a way to fix this for free (nevermind that my electronics, speakers etc. are a ticking timebomb from all of the soaking) I am going to find a lawyer who is looking for a fat juicy class action lawsuit.

  • It finally rained here and my newly purchased 2008 Enclave sunroof is leaking, so came here and found out about all the problems and recalls and now need help fixing it before the mold thing starts.
  • It was strange - I texted my usual service rep at the local dealership that I would be bringing my 2008 Enclave in with a leaky sunroof. When I showed up the next day the service manager took control of my case himself, rather than my usual guy. We went back and forth a bit about who was going to pay for the repair since it was such a well documented issue - and that there had been a recall for 2008s with the same problem. Later the same day I got a call from a dealer salesman to see if I wanted to buy a new one instead. To make a long story short, we ended up buying a new 2012. After reading about the many electrical problems etc. that can result from repeatedly soaking the dashboard, and learning about the many upgrades to the engine and transmission since 2008, which had also given us concern over the years, we bailed on the old one to avoid almost certain future problems. They gave us a good deal and GM pitched in an additional $1500 due to the leak issue. Not at all what we had planned on but I think it was the smart decision in the long run. However, I still filed a complaint with the National Highway Traffic Safety Administration documenting the many problems to 2008 Enclaves that were excluded from the original recall and I strongly encourage anyone with this issue to do so as well.
  • It was just a about a week ago that my son came to me and said there is a drip coming from the ceiling of our 2008 Buick Enclave. What? the ceiling! Sure enough there was a drip coming from the sensor that sets in the center above the third row seats.

    Fast forward to today...its raining outside and my wife gets in our car, puts on her seat belt and it is all wet. she drives out of the driveway and hears a big slosh of water above her head and its NOT on the outside. The water is coming in somewhere and I have to find out where fast. I log in to to see what the issue might be and seems to be a big issue.

    Not sure if my VIN was in the "elite" group that was recalled but I can say that if it wasn't I will be looking GM to step up to the plate here. I am in a similar situation with mold issues...I and two of my three kids have Asthma and they will not do well if this water turns my car into a moldy mess.
    It appears that even if they replace the seals in the sunroof (that seams to be the problem area) it often becomes an issue again later. Possibly the vehicle frame did not match the sunroof glass very well in '08.

    GM has made a great vehicle here and we have enjoyed our Buick Enclave but I can not afford new seals, carpet or electrical repairs so if GM can not (or will not) own up and fix this issue quickly for us, we will have a car for! and GM will not get a second chance from us.

    Has anyone had any luck getting their leak fixed? I have no warranty left (e.g. 108K miles and my extended warranty just expired) so I am hoping someone can direct me to an inexpensive or free repair.

    Thanks in advance for your replies.

  • I am experiencing the same issues as most of you with the 2008 model, however this is a 2009 model. I want to know why this is happening. The dealership is going to correct it but only because I have owned the suv for 2 days. Purchasing this vehicle makes me weary of the brand that I always trusted.
  • amyr1216,

    We're glad to hear that your dealership is working this out with you! Please keep us posted on the progress of the repair!

  • I purchased my 2008 from Stanley Ford in Pilot Point, Tx in May 2012. This dealer was informed of the water leak within 1 week but the dealer failed to help at all. After numerous calls and taking the vehicle back & forth to the dealer where I purchased the car, I went to the Buick dealer in my area McKinney GMC Buick and found out that there was a recall on the sunroof. Although my VIN wasn't listed on the recall, I contacted Buick's customer recall number and currently they're looking into this issue. Hopefully this issue will be handled without any added cost to us the consumer. Waiting on a reply now, stay tuned.
  • My 2008 Enclave also leaks water from the sunroof resulting in wet front pillars and a wet floor on both the driver and passenger sides. I have had the problem for more than 2 years but had not taken the time to get it into the dealership until 11 days ago. The dealership said they fixed the problem on September 10, 2012 but the car hasn't been out in the rain since so I'm not yet sure it is fixed. I contacted Buick customer service asking them to pay for the repair but they denied the request saying the following

    "our experience has been that a defect attributable to the original manufacturing and assembly process generally makes itself apparent quite early in the life of the vehicle. After a vehicle has been in service for several years, many factors (usage, owner maintenance, age and wear, etc) can contribute to difficulties that are beyond the control of the vehicle’s manufacturer."

    I am more than a little disappointed at Buick's decision since they had both a TSB and a recall on this issue (though my VIN wasn't in their list) and that a sunroof leak is obviously a design flaw unless the vehicle has been altered or wrecked. The customer service center also mentioned "debris" that could cause a blockage but there is no reference in the owners manual to cleaning the sunroof drains (nor have I ever heard of a car where sunroof drains needed cleaning).
    Does anyone know of a way to appeal / elevate a decision made by Buick Consumer Support?
  • Good morning woodland22500,

    If you were to send the Service Request number (71-**********) or the last 8 digits of your VIN to us at we could check into what's been done in your case. While we may not be able to change any resolution, we will check to see if there is something we can do.

  • Sarah: I am glad I came across this blog. Yes you guessed my Buick leaks too and A LOT!. I have an Enclave 2008 Custom made only 41,253 miles on it. I paid +46 K$ (Full MSRP, no discounts on it!), mater of fact I am still making payments on it. Everything was fine with it until last December. My wife noted some humidity on the passenger side but we were in Orlando on vacations, so we decided it could wait until January, But the warranty expired January the 4th .So long story short, yesterday 9/24/2012 my wife took the kids to school and when they open the DVD screen there was a steady dripping of water for almost 5 minutes out of the thing, now on the driver side also there was almost half inch of water soaking all of the carpet, not to mention the strong smell. the water seems to be leaking out of the driver airbag located on the column, it is stained around that area. VIN# 8J220363, Miami. What can I do next?

  • We've just encountered the same issue, purchased 8/9 with 49k, 2008 CXL. Last week, we were on vacation and parked outside for an extended period for the first time. On the ride home, we stopped and opened the trunk to get some things and there was water dripping out of the park assist/roof area just behind the 2nd sunroof. Has anyone tried to blow debris out of the sunroof tubes or is anyone having success with getting this repaired, a quick internet search shows its more than an occasional issue.
  • hi, sorry to hear that. The clogged drain tubes seems to be where the service folks always want to start but it definitely had no effect for us and no one else i have heard from. The problem was the leaky sunroof itself. best of luck to you.
  • we had ours fixed at a Buick dealer. they "cleaned sunroof drains and added extensions". charge was $279. I contacted Buick to ask them to pay for the repair but they refused. Not sure I will ever buy another Buick.
  • Good morning rellbg09,

    We're sorry that you're having difficulties with your sunroof potentially leaking on you. If you decide on working with a dealership and would like for us to check into this further, please send more details to and we'll get a Service Request started for you (we would need your name and Edmunds username, phone and address, the last 8 of your VIN and current mileage, and the name of your preferred dealership).

    My first Buick, I was so proud of. I bought it in 2010, first time we had rain, my friend and I were out shopping, got into my "oh so proud of Buick" as soon as I put it into drive, water came out of the driver and passenger side arms and leaked all over us. I was so not happy and embarrassed. As I was taking it back to the dealership, power steering started making a terrible noise. I told them about the problems and the mechanics said they have had recalls and problems with them. I should of just traded it in right then. I have had problems for the past 2 years, sometimes it would leak and sometimes it wouldn't, but you could always here the water swooshing around above you and beside you, crossing your fingers it would not leak on you or your passenger/s. Well, this past week we have had some long rainy days and my passenger and driver side floors are soaked!! I spend my evenings with the shop vac to get the water out. I am currently building a garage, so I have no choice but to leave it outside. Just called the dealership to have them look at it. I started reading all these post and I think I am going to definetly be looking for a new vehicle!! I'm not going to be embarrassed by something that I should be proud of.
