Buick Enclave AC Problems



  • Like many others in this forum, we are experiencing the same problems.

    We bought a 2008 Enclave used from a dealer in Jan 2012, and I don't usually buy extended warranties, but for some strange reason I did in this case and very happy for it! A month after purchasing the vehicle, things started to go wrong and things have gone down hill from there. My wife loves the vehicle, except for all of the time it has spent in the dealership.

    In Feb 2012, we had an issue where we could not remove the key from the ignition. We could start the car, drive it and turn it off, however, could not remove the key and were therefore unable to lock the doors. We called the dealership and then a service truck and he couldn't figure it out either. He removed the negative wire from the battery so we could at least lock the vehicle overnight before taking it to the dealership. When we got it back, the trailer harness, that was installed by the dealership did not work. The technician suggested that the electrical for the harness shorted out the left turn signal that caused the ignition problem. I just laughed.

    So we get the vehicle back and the left turn signal will not stay on. Took it back to fix that in the summer when we started having AC problems. Could not get AC, then the car would overheat, and they replaced the water pump. Now we have the AC/heat problem others have described in the forum... coincidence? I think not! Sounds as though all of the Enclaves have the same problem... I would be interested to know if this is a problem confined to one manufacturing plant or geographic region.

    In any case, winter is coming, we have had the vehicle to the dealership twice and they can't figure out what the problem is. In summer, when AC was supposed to be blowing, heat was coming out. Now when heat is supposed to be blowing, cold comes out. Here is the kicker, sometimes the problem is in the back (under auxiliary blowing on my two toddlers), sometimes, the problem is on the passenger side and sometimes on the driver side.

    I am not sure what the problem is but could it be the temp control module in the computer system?

    Any comments appreciated, and by the way, I too wish I visited this forum before buying. I thought I performed more than ample due diligence, but apparently not.

    Thank you in advance

    Hello trygiven,

    Sorry to hear that it's been so difficult to get some of these concerns resolved on your Enclave. If we can check into this situation further with your dealership, please email us more information at [email protected] so we can start up a Service Request and contact the service department (include your name and contact information, the last 8 digits of your VIN and mileage, and the name of your dealership, as well as a brief summary of the current situation).

  • jdkoren -- I, too, had a similar (though not identical) problem with my Enclave (see post #147). After several visits to my dealer in which they claimed they could find nothing wrong (while giving me that "You must be imagining this" attitude), they suddenly discovered the existence of a Tech Service Bulletin, #08-01-39-009B, that exactly described my problem. The fix involves reprogramming the heater module ($100), but it has cured the problem. Guess you need to take the service manuals and bulletins with you when you have these cars serviced. Anyway, I'm happy for now!

    I have a 2009 Buick Enclave that has had 3 A/C problems in the last year. The A/C would stop blowing cool in the front but blows warm and fast in the rear. I tried to increase the fan speed but it would not increase. The front vents were barely blowing cool air. I tried to turn off the A/C and it wouldn't go off. So I turned off the entire system for about 10 minutes and turned it back on and it worked OK. I brought the Enclave into the dealer on all 3 occasions but they could not duplicate the problem and said the A/C checked out fine and the computer showed no problem codes. This is a very disturbing problem and living in Florida it is imperative that the A/C works. I'm very happy with the Enclave otherwise but if GM cannot fix this obvious defect I will have to sell the Enclave and replace it with a NON-GM product.

  • I have a 2008 Buick Enclave that I purchase pre-owned in 2009 with 20K miles. I love the style, the room and features of the vehicle but I'm very disappointed with the mechanical problems. A couple of years ago the rack and pinion was replaced. I noticed the steering felt odd and this was replaced under warranty. A year after that the steering started doing the same thing but I was told that it was a different problem which would cost me $800+. Last year I started noticing that my AC wasn't very cool and on our way home from Disneyland in October 2012 the air gave out completely. I took it in and was told the evap core had to be replaced and it would cost $1200+ to repair. So I'm driving this beautiful car with jacked up steering and no AC which just upsets me greatly. I didn't purchase an extended warranty because I figured that Buick was a quality product although I have 86k miles and it would have expired by now. I've never owned a 4 year old vehicle which such major problems. The weather is going to start warming up and I'm going to need AC soon but I don't have the money to fix it and I won't be able to get a good trade-in with the problems that it has.

  • I bought a 2012 Buick Enclave in Oct. 2012. At 900 miles, it started to miss out on a cold start and blew black smoke through the exhaust.This went on for about 30-40 secs. The gas smell was so bad you couldn't walk behind the car without getting nauseated. I contacted the dealer and they said it might have had some moisture in the tank. It continued, so at 1500 miles they checked it and found a #1 cylinder misfire and fouled plug. They replaced the coil and the plug. I picked it up but the next day it did the same thing. They then replaced the #1 fuel injector-they said it was bad. It was there 2 weeks waiting for an injector. It missed out but very slightly when I picked it up. The next morning it did the same thing. They have since come up with a memo written in 2011 saying that because of EPA standards they have to flood fuel in to heat up the catalytic convertor to close the loop and make it run more effiecient. It's funny that it didn't do it for the first 900 miles. I have checked with 6 other Enclave, Traverse and Acadia owners. None of theirs do this. They have the same engine. Some of them do it some don't. There has to be a fix. I asked the GM area rep if the memo was an excuse or a reason. I can't imagine the EPA wants the atmosphere flooded with exhaust fumes and black smoke when I first start my car. My exhaust pipes are full of black soot.

  • I too have a Buick Enclave 2008. After 1 yr of having the vehicle, I had to have a complete overhaul of the transmition, windshield washers replaced, a coil under the hood corroded, radio is faulty. Meaning the volume only plays on 1 side of the vehicle and the dealership said it wasnt covered under warranty. Now in 2012 my transmition had to be overhauled. From the very beginning, this vehicle was a lemon. Yes, its beautiful to the eye, but very costly to purchase and repair. The dealership can't seem to catch whats going wrong with the vehicle unless a code pops up. They don't have to be mechanics anymore; only requirement is to know how to read. Just as the person that is responding to these blogs keeps saying the same thing over and over about not being able to help but you can send her/him your information if you want her/him to look into it for you. What a joke Buick Service and product has turned out to be.
  • I agree with your statement "Just as the person that is responding to these blogs keeps saying the same thing over and over about not being able to help but you can send her/him your information if you want her/him to look into it for you. What a joke Buick Service and product has turned out to be."
    It's pathetic. Just tell everyone you know about your experiences and If everyone does, GM will learn real quick when they stop selling vehicles that they are going to have to change their ways.

    Have you tried getting a second opinion from a different dealership? Normally we do recommend sticking with one dealership as they would be more familiar with the history of your vehicle, but sometimes it's helpful to have a fresh set of eyes.

    tadpolegal --

    Actually, I was able to get my problem satisfactorily resolved after the GM Service people intervened on my behalf following my original post in this forum. Until then, I was getting nowhere with my dealer, but once GM Service got involved things started moving very quickly and I found the dealer actually began listening to what I had been trying to tell them. So, in spite of having some initial problems with my dealer, I have to say that the GM Service people were very responsive and helpful in my case. Maybe you should give them another chance!
  • Well I have an update to my issue since posting on 1/26/13. I had emailed GM customer service on the same day and someone contacted me first thing on Monday morning. GM contacted my local dealership and made an appointment for me to take the car in to diagnose on 1/29/13. Once the diagnosis was made to replace the steering rack and the evap core GM agreed to pay a good part of the repair. I had no warranty left but GM was very concerned about my problem and made sure that they looked into the problem. I have to say that I was very pleasantly surprised that I was taken care of so quickly and efficiently. A total of 6 days and my car is now repaired and I only had to pay a fraction of the cost. GM is definitely doing their best to improve their customer service and the dealership was equally accomodating. Don't hesitate to contact customer service if you have an issue with your Enclave or another GM product, you might just be surprised at how willing they are to help.

    Boy do I feel like a sucker, bought this beautiful Buick Enclave for my wife to drive, got a great deal on the purchase and now I believe I know why I got suck a sweet deal. The car should be painted yellow ( lemon ). It has been back to the dealer for several different problems. First time it was the power steering, so far that repair is working well. ( 2nd time ) Then we had it in for AC problems. They managed to fix it for a while but the problem is back and the outside temperature is rising. Third visit to dealer was a bust. Took it to them with strong concerns over how the car was riding, our beautiful Basically the dealership keep it 2 days and stated that they could find nothing wrong with the way the car rode, that this ride was to be expected of a used car. I then contact Buick and also got a call from GM, after a couple of weeks of so called investigating GM called to tell me they were closing the case, that they also felt that nothing is wrong with the car. In the nicest way that I could I told them that they were wrong and that I would not be the owner of this car much longer. I am still shocked that General Motors is allowing something like this to happen. Its obvious that this is not an isolated case, the Enclave problems are really becoming well known, just type in Buick Enclave in Google and you can read for hours. Lastly, I am completely in awl that Buick has brain washed their people into telling the customers that their is nothing wrong with their car. I have never been a complainer, but since I bought a Buick I have become a very unhappy person when it comes to this car. Looking at trading it off and just hoping to get something for it in trade for some brand other than a GM.

    Well, I thought I was Special, then reading all of the posts I found that this is the norm... 09 Enclave In for service again right now 45000 miles, Steering rack #3 (2nd in last 2 weeks).Now the laundry list of replaced items

    Steering column---for rubbing & ratcheting noises while turning
    Indash video display----kept getting error internal problem
    AC evap core----cracked would not hold charge(had to remove interior to replace)
    front struts----leaking oil
    Timing Belt---(had to remove engine to replace)
    Power Steering Pump----severe noise on turning wheel
    Tires---totally worn out at 26000 miles (Michelin Latitudes)
    Steering Rack & Pinion---3 TIMES same problem all 3 times did I say 3TIMES
    Oil Sending Unit--Causing car warning to STOP ENGINE IMMEDIATELY

    All Items requiring me to go back & forth to the dealer at least twice for everyone of these repairs because the either did not fix right the first time or broke something else....UGH!!!
    Sorry more like a rant than a blog

    My husband bought me my dream car as a mother’s day gift last year – it was a certified GMC so we thought great no problems. The care had 36 – 38,000 miles (I can’t remember right now) – and no problems until this past year. Of course, the AC / heating system has messed up – and I was told when I called I was just over my warranty by 300 miles so I would have to pay to get it fixed (I was told this several months ago). Now the passenger side constantly blows hot air and in the rear only cold air - no matter what temperature it is on. My kids are either sweating or freezing - it's crazy! I decided I would just have them check it out when I took it in for the oil change, but last week the problem got worse. To top it all off the service brake light came on and the stabiltrak is flashing and saying it is off. They have told me that that there is fluid leaking from the master cylinder to the brake booster and to fix it $945 – and this must have been a defective part?? The A/C and heat problem are the temperature actuators for the passenger side and the rear and to fix this $655 plus the $165.00 I have to pay just to tell me what is wrong with it and all because of defective parts? I will never have another GMC – you really stand behind the certification. The guy at the shop just acts like oh well - your problem - and told me you should have brought it in earlier (about a/c problem) I can't go on what you say it has to be noted by being seen in the dealership.

    I feel the same way! I have a 2009 Enclave that I bought new. I took by car into the dealership in March of 2012 because the air conditioning was not working. I had noticed in the fall before that at times it would sometimes make a noise but only a few times and then I didn't need the air again until March. When I did it was not working at all. I took it in and they charged the freon and added dye and told me that it likely just needed freon and but if I had issues I could bring it back in and they could find the leak because they had added the dye. The air worked great and I did not have an issue again until this spring when it was time to use the air again and it was not working. I took the car in and again got the freon charged and the dye added and made an appointment to come back in since now I knew there must be a leak.

    When the mechanic found the leak they said that it was in the evaporator core and that it would need to be replaced. He said that he himself has made the same repair on four other Enclaves. That number seems excessive in one dealership. I also saw many posts about this same issue for Enclave owners. I find that there seems to be an unusually high number of this type of repair.

    I have contacted customer service and have been patient but it does NOT seems that GM is going to stand behind there product. I believe this to be a known issue even though there is no recall regarding the evap core. The last four vehicles my husband and I have purchased where GM. I expect more from their "luxury" line. If they do not come through and do the right thing here I do not believe we will purchase a GM again. This is very disappointing considering I really love this car and I am asked often about how I like it.

    Hi jas_kare,

    I apologize that you've had this trouble with your vehicle. Were you given a customer care case number when you spoke with GM Customer Service in the past? If so could you provide it to me, I'd like to research more on your concern. I look forward to your response.

  • atisdaleatisdale Posts: 4
    I have gotten no help from the GM customer service at all. I was told that they would not help with the repair. I truly think this should be a recall since so many people have had this problem. I was told that they would not help me because my vehicle was not properly maintained but was given no reason as to that conclusion. I have had all maintenance done on my vehicle. I am SO frustrated going back and forth with them for two weeks for them to just tell me that. I'm so upset that they have ruined how I feel about my Enclave when they could have had a customer for life. Do the right thing!

    I feel your pain. I have a 2010 Enclave which was the perfect car for our needs with the hugh space in the back. I have put on quite a few highway miles in 3 years (69,000) and with the exception of an air leak in passenger window creating a whistle and the drivers seat heater turning off prematurly it's been a great ride. The air conditioning season has just started and mine is not working. Also noticed some problems at slow speed with the power steering. Into the Buick dealer today and $1,400 to fix the power steering another $200 or so for the air conditioning; on a 3 year old car!!! Now I come onto this forum and find out many other Enclave owners are experiencing the same problems.
    I've had GM products in the distant past and swore never again (remember the Vega with clutches that disintegrated right after the 12K warranty expired along with the rust that set in at 14k mile? Or the Regal with the rear window falling out as I left the car dealership on day 1?) but the Enclave with it's unique design and size caused me to cave.
    I will be buying a replacement for the Enclave in a few months and considered buying another one, but after today I'll hold off for the redesigned Highlander with the added space
    coming out this fall.

    Hi jas_kare

    I can look up your vehicle information to see if there are any known recalls on you Enclave regarding the concerns you've described. If you are interested just provide the last 8 digits of your VIN.

  • I am in the same boat as most of you. My 2010 Enclave, formerly dream car as well, just at 52,000 (2,000) past warranty, has had to have the AC condenser replaced at a whopping $1700. The sad thing is that a funny smell was coming out of the ac (I was told it was the oil and freon mixing together by the service man) at 49,000 and I SHOULD have brought it in, but thought it was silly to bring it in for just a smell. Very frustrating that this is a recurring problem and GMC will not take care of it. I thought the Enclave would be a car I would buy again in eight years, but not now. :(

    I wanted to add that if you smell something funny from your Buick Enclave AC, bring it in. It's the freon leaking. Wish I had of known that earlier! It started at 49,000 miles and I felt silly bringing my car in for an odd smell. I thought maybe I picked something up from the highway. Then at around 52,000 the hissing started and the AC wouldn't cool on the passenger side or back seats, only on the driver's side. This repair is costing me close to $1700. (Found out today when I brought my car in that the smell was the freon leaking the whole time.) I am just truly dissappointed that this broke in my car so soon! It's a 2010 and only 52,000. What happened to quality Buick products? I truly wish that GM would step up to the plate and take care of this problem since it seems to be happening so often. I am very disappointed in my "dream car". Very sad. I won't be getting another Enclave, which, until today, I was thrilled at driving.
  • gmcustsvcgmcustsvc Posts: 4,252

    I looked up your VIN and there aren't any open recalls listed for your vehicle. I also looked into the steering concern you mentioned, and there are also no technical service bulletins currently listed regarding this for the 2010 Enclave. If you have any future concerns please feel free to reach out to us.

    I think I'm going to have the same diagnosis when I take my 2009 Enclave in on Tuesday. The A/C does not get cold at all and the air only comes out of the 2 center vents and feet. Switching modes does nothing as the air will not come out of the defroster and very little out of the side front vents. A cracked core is something I was hopning it wasn't going to be, but reading all these posts, it seems I'm in for it. I had my doubts when I bought a this thing back in October because it was a GM but it had everything we wanted/needed in an SUV. I should have listened to my gut - NO MORE GMs!! :sick:
