Buick Enclave AC Problems

1246789

Comments

  • We own a 2008 Buick Enclave that we purchased in October 2007. Overall, we love the car. However, we continue to experience electrical problems that have not be corrected. At times, the air conditioner/heater will not react to my trying to adjust the temperature or fan, the cd/radio/navigation system will not work, the side mirrors will not adjust, the windows will not go down or up, the blinkers are erratic and traction or other indicators appear on the dashboard screen. Mosst times, if I cut the engine off and then on again, these issues disappear. Our dealership has trouble-shooted these problems but cannot find the cause. I've even gone there when these issues were happening and they still could not determine the cause. So, for now, I just hope that these problems don't occur when I'm on a trip and/or the weather is not too hot or too cold.

    I have had my enclave for 2 years. Last year no problem with the climate control system. So far this year it has been in 5 times. The defroster blows cold air when on with the floor heat. The techs re programmed the unit ( 3 months ago). It continued to be a problem. If we put the heat only on the floor it is ok, but I live in Michigan, I need a defroster! NOW I am told they compared it to a gmc and it was normal for the floor heat to be 40 degrees warmer than the defroster. I am leaving on a trip to Florida and I am very concerned about not having a properly working defroster if we run into bad weather. Has anyone else had the same problem? We end up putting the temp up to 85 to offset the cold air in order to have a defroster. And we run the fan at the highest level. I really do not think this is (normal). Dealer is kohen in marinette wi.

  • My '08 Enclave has been a complete lemon. We are one of the first owners in May 2007. HORRIBLE vehicle. Multiple issues. CURRENTLY, June 2011 in shop for AC not working. Service could not find leak. I had to pay $130 to add a pound of freon. April 2012, out again. Could not find leak. Another $100 to add 2 pounds of freon. Leaked this morning in garage, back into shop. Heard there are 17 vehicles with the same problem nation-wide. Has anyone had any luck getting a resolution from Buick. I tried Customer Service, and the rep just phoned dealer to get info. Nothing new. I am so frustrated with this vehicle. It is always in the repair shop. Out of warranty and on ME.

    They will occur again, for it happened to me. I just got back from a trip through the San Bernardino heat and the A/C was not working as you mentioned. Nothing I did made it work. I switched the fan to high, turned on and off to see if that would work and took the auto feature off, but nothing. 106 degrees and climbing and no A/C is definitely a concern. I just got a call from the dealer and they state it will cost me $1,300 to fix. That is no chunk change.
  • I feel your pain. My Enclave was in the shop 7 times for the A/C and at 66K miles was on its third transmission. GM didn't care one bit. It was a beautiful car and I loved it but practicality made me trade it in last September for a nice reliable Ford Edge. I will never buy GM again!

    Hi Sarah,

    I responded to the email address you provided with the information you requested. Thank you for being proactive here in this forum and hope the information I included helps.
  • mcompmcomp Posts: 4
    I am so ecstatic right now and have to commend on the great way GM and their staff assisted and handled this issue for me. Soon after I commented on the A/C issue I had while driving though the San Bernardino heat, I received an email from Sarah asking for more information to be posted in the socialmedia@gm.com site, so I did. I just got a call back today and they will assist me with this issue and the cost will not even come close to what I posted. I am so happy that I can use that money to pursue original plans to get my wife the Buick Verano she likes so much over the July 4th holiday, rather than spending it on the A/C issue. I was thinking twice about it when this issue came up, but if GM is going to have our backs as customers, then they sure as heck have my loyalty. Thank you GM, Sarah and all those involved for your assistance.

    Thank you Sarah and Christina for your time and effort in assisting me with this issue. You have truly made my day.

    Yay! We're happy to have been able to assist and I will pass your kind remarks on to Christina as well.

    All the best,

    I am having similar problems to those posted in this thread. I have a 2008 Enclave that I bought used with ~ 30,000 miles on it. At 49,000 miles the power steering pump failed, but was still under warranty. Just after 50,000 miles, we noticed the AC wasn't working properly. The air coming out of the vents wasn't as cold as it should be. On longer trips, the AC would start out fine, then the air would gradually become warmer and warmer. Along with the elevated air temps, the flow would gradually decrease until little to no air was coming out of the vents. Even with the system in manual, the air flow could not be increased despite increasing the fan setting to maximum. I took the vehicle into the dealer at 53,000 miles and they could find nothing wrong except the freon level was low. They recharged the system and added a dye to check for leaks in the future. The AC worked fine for a short period of time. After 2-3 weeks and a few more miserable long trips with symptoms identical to what has already been described I brought the vehicle back to the dealer again. They could find no leaks, but the freon level was again very low. They recommended the front evaporator coil be replaced to the tune of $2,000. They stated this wasn't even guaranteed to fix the problem. It's a best guess. That is a lot of money to spend on a hunch. My wife and I are still debating what to do. We are extremely frustrated that an '08 is having this many problems. It's also quite unsettling that a vehicle just removed from warranty needs such a costly repair. We're strongly considering taking the vehicle to auction as is and buying a new Mazda CX-9, Toyota Highlander, or Honda Pilot. I may never buy a GM vehicle again. I love how the Enclave looks, but it has really been a lemon for the 18 months that we've owned it.
  • I also loved this car....the most beautiful car I had ever owned. Mine was an 08 model but I bought it used in 08 with 19K miles on it. It was in the shop 7 times for the AC and I was on my third transmission. It was just an on-going battle and it got to the point where I didn't trust it to go anywhere other than short distances as I wasn't sure it would get me there. I was fortunate in that I never had to pay for any of my repairs as they were covered under warranty. I don't know what I would have done if they had not been covered. After 3 years, I traded mine in last September with 66K miles on it for a 2007 Ford Edge with 37K miles on it. I don't love it the way I loved the Enclave as it's not as roomy but it drives just fine and I have had no problems at all with it. Good luck!

    I also have a 2008 Buick Enclave that I purchased used with 31,000 miles in 2011. I was assured it was a certified used car. I have had nothing but problems with it starting at about 40,000 miles with the steering column squeaking real bad. What has been my most expensive car purchase in my life has been the mistake of my life. Thank God I purchased an extended warranty, because I had to have the steering column replaced. Then right after that, my car would shift out of gear while idling at a traffic light. It would stay that way. I was told it was a sensor, that was replaced. Then 3 weeks later the same thing happened again. This time a DIFFERENT sensor. These were covered under warranty as well. NOW, for the past 3 weeks, I have been having issues like everyone else with the AC. The AC light starts blinking then shuts off, but fan keeps running, or stops running altogether if I am sitting in park or idling for more than 4 or 5 minutes. This is the most unreliable car I have ever owned. I had to take my daughers car on a road trip because I was afraid mine would break down. It seems to me that GM needs to step up to the plate and recall all these Enclaves because they are aware these issues exist. I have owned several GM products over the years, with little or no issues, but unless my local dealership practically gives me a new car, I more than likely will not own a GM product ever again.

    whatsnext,

    I can imagine these multiple concerns that have come up have been frustrating for you, and I'm sorry that this has been your Enclave experience so far. Are you still within your warranty to get the AC fixed? If we can look into anything, please don't hesitate to get in touch with us at socialmedia@gm.com (include the last 8 digits of your VIN as well as your name and Edmunds username).

    I sold mine some time ago. I just couldn't rely on the car. I did take a beating on the sale but very happy not to still own the thing. It is rediculous that several dealers told me that they had never heard of the AC problem!

    Vote with your checkbook....don't buy GM again!

    I’ve got a similar issue with my ’08 Enclave here in Arizona.

    In the summer a few years ago, my son had fallen asleep when driving to the Phoenix Zoo. Instead of wake him up my wife just parked and idled the Enclave with the A/C running. After a while the air flow coming out of the front vents got slower and slower, until there minimal air coming out the front vents. (similar to instanced described earlier in the thread). After turning the car off and letting it sit for a few hours the A/C worked fine again.

    It happened again shortly after that on a summer drive from Prescott back to Phoenix. (about a 2hr drive). About an hour into the drive the front vents again slowing began to loose air flow, with the fan speed selection having no effect on the flow.

    After this incident is when I discovered this Edmunds thread, and took the car to the dealer. The dealer couldn’t reproduce the problem, but make sure the system was charged with refrigerant. After reading this thread, we make sure that the AUX climate control is always on when we drive (and make sure that our young children haven’t messed with the rear temperature settings by bumping up the rear of the vehicle by +10degrees). After doing that, we haven’t had an issue for quite a while until yesterday.

    It was around noon, outside temp ~100deg, humidity ~25% (first humid day of the summer). We I turned on the car, the air coming out of the front vents was warm and wouldn’t cool down. The AUX button was enabled, and the temperature setting in the back of the vehicle was +0deg. It took 15min for air to come out of the front vents to be cooler than the outside air temperature. The car then parked for 1 hour. After that hour, on the drive home (10min) the A/C never cooled down. I drove it again 3 hours after that (4pm, 110deg), and the front A/C blew cool immediately upon startup of the vehicle, and was basically “normal” throughout the 20min drive I was checking out the A/C.

    On thing that I did notice in trying to debug this latest A/C issue is that the air blowing out of the back vents was warm(not cold), when:
    - the front vents were blowing cold
    - the AUX button was enabled
    - the rear temp setting was set to +0deg.

    (I feel bad, I think I’ve been blowing warm air on my kids for a while now, but they’re too young to know that that is a problem or something out of the ordinary)

    The first issues to me seem like and engineering/design problem. Maybe the latest is just a maintenance/broken part issue. But with the quirkiness of the A/C on this car, you wonder if you fix something if you’re really fixing the problem.

    So, I’m off to the dealer in inquire. What’s bad now is that the Enclave has 60K miles and is out of warranty.

    I'll also send an email off to Sarah at socialmedia@gm.com.

    We live in the U.P. and never had the A/C problem here. Only when we drove south towards Florida did we experience the problem. In one instance I found that, after feeling warm air, I stopped and found that the A/C coil was frozen. River's of water drained off the car, then .5 hour later, the A/C worked. This was not a charge problem! I believe it is/was a design flaw which GM never admitted to! I think there is a chance that they modified parts, so later models don't have the same issue? Mine was an 08.

    I just found this site as I was researching a problem with my AC that I was having with my 2008 Buick Enclave CXL. I have had the same issues as many of you have noted, especially rjluke(post # 107). This has been the most expensive purchase I have made for a car! I bought it used Feb 2011. 2 weeks after purchase, our fuel pump went out. Then I had breaks changed and had issues with them. Then steering wheel starting making a strange noise and had to get the rack and pinion replaced. Then later had to get something else replaced in connection to my steering(the power steering casing maybe?). Then had a seal leaking oil and had to have my engine pulled and the seal replaced. I was told I had a full warranty on the car when I got it then found out later from a Buick dealership that it was limited and only for a short time did I have it available.
    I drove fromTn to Va shortly after buying the car (summer of 2011) and noticed the air getting warmer in my car. I tried turning the fan up and it did nothing. I have asthma and hot humid air is a trigger. I got to Va. and no dealership was open. I stopped to let my car sit for a while and went in to a restaurant cause I could not breathe. When I came out it was working again. I took it to the dealership in Knoxville, (Rice Buick) and they said they could not find anything wrong and were not familiar with the problem. My car was under warranty at this point. It did it another time as I was driving around showing homes (I am a Realtor). Took it again to the dealership the next day and again, they said they could find nothing wrong.
    This summer, it has already happened to me again, but of course after hours of the dealership and I am of course out of warranty now.
    I am getting ready to make another trip to Va and am worried to death that my AC will go out again. I agree with others that say there should be a recall on this. I also notice that my AC drains a lot of water from under my car. This cannot be right. I feel like something is freezing up. It is like my blower just stops. I can hear the AC running but no air is coming out. I would also appreciate any help from Buick!!
  • rjlukerjluke Posts: 7
    Contact GM and have them open a case file for this. The more people that bring this issue to GM's attention, the more likely they are to issue a recall. I think there are some major design issues and/or manufacturing defects with this vehicle (the 2008 model in particular). Power steering, AC, leaky sunroofs just to name a few. A vehicle in this price range shouldn't be having so many major failures in the first 50-60,000 miles. It's not acceptable.

    Be ready to get wait a long time for any satisfaction however. I am still working with a GM rep trying to get this issue resolved. It is taking forever! I haven't had AC in my vehicle for nearly a month now during one of the hottest summers on record. It's not very pleasant to get inside this vehicle after it's been parked outside all day where I work. Not much cooling to be had with the windows down when it's 100 degrees outside.

    Until the AC issue is fixed, I have to cram my family into our 1999 Infiniti G20 to go anywhere. Great car by the way - never a single issue with it. It's a 1999! The 2008 Buick Enclave has been a huge disappointment thus far. GM needs to step up and stand behind this vehicle and all its problems or consumers will avoid GM products and tell anyone else who will listen to do the same.
  • I opened a case file for my 2008 Enclave and it got me nowhere. I specifically asked my rep to let me speak to his supervisor and he basically told me that there was no one else I could talk to. I told him that unless he was the president/CEO of GM, then there should be someone above him I could speak with. I was never given the chance to talk to a higher up. I even received an email from another rep telling me that GM would not discuss the issue with me anymore. My 2008 Enclave was in the shop 7 times for the A/C and I was on my 3rd transmission when I finally got fed up last September and traded it in for a Ford Edge which has given me no problems at all!

    I would love to trade mine in but I know we are upside down on it. I am just praying for a big real estate deal in which I can use my commission to pay the difference in a trade! I am really very disappointed in this car!

    Thank you Sarah! I will get that to you as soon as I can!
  • I purchased this car in December of 2010. Last summer I had noticed the air conditioner stopped working. I brought it to the dealership. They ran a dye test and could not find the leak anywhere. The re charged the air and it worked for the remainder of the summer. Flash forward to 3 weeks ago once again the air stopped working. It would only blow HOT air. I have 2 small children so this was not going to work. Once again I called the dealership but now I am out of the warranty by a little over 3000 miles. I brought the car to our local repair shop who works on my husbands company vehicles. Well let me say the nightmare began. The repair to get the air conditioner to work once again cost me $1680.50. I needed a new evaporator core which is located behind the front console of the car. The entire dashboard needed to be removed to repair the issue. The labor that went into fixing the problem was over 10 1/2 hours. I was without a vehicle for almost 3 weeks.

    The money that I pay for my car and to have such a major issue is ridiculous. Never never again would I buy a GM car. I have brought this car in several times already. I had to bring it in for the steering wheel issue alignment issues tire issues and now the air conditioner. That is about all I can take.
  • rjlukerjluke Posts: 7
    I have the exact same problem with my AC system. It died just after warranty expiration. This after the power steering pump failed at 49,000 miles. The dealer re-charged the freon and did the dye test. That lasted about a week. Brought it back in and they could not find a leak. Freon once again low. The dealer gave me an estimate of $1,675 to replace the front evaporator core, which they said "might" fix the problem. I haven't scheduled the repair yet. GM needs to pay for this and guarantee the repair will solve the problem. Having these major failures on a car with this many miles is unacceptable. I have a case file established with GM, which so far has gotten me nowhere. I'm still waiting for my case manager Tony to get the information he needs from my local dealer. He's been working on this for over 2 1/2 weeks - still "trying" to gather data. I've been trying to get in touch with him for the last three days, but he is not returning my phone calls. That is also unacceptable. I am running out of patience. It's beeen almost a month without air conditioning during a very hot summer. GM needs to issue a recall for this. There are way too many people having the same issue and all at about the same mileage. Either there is an engineering design flaw, poor quality parts, and/or a manufacuting defect with the AC system (as well as the power steering, which is another issue).
