Buick Enclave Maintenance and Repair



  • Had the same issue. Found out that my iPhone sets off the censor. Can't lay it on empty seat, can't have it in pocket or purse. Hope this helps
  • buckeyewife-thanks for the quick reply. How did you figure this out? Also where do you keep your cellphone while in the car? I have another service appointment on Monday and would like to experiment a little over the week-end.

    the service tech at my dealership found this info. I keep my phone in the door pocket, center council change pocket, or on the little open area near the gear shift. Hope this can try it without going to the appointment by turning your car on (don't sit down) put your phone on the passenger seat and see if your light comes on.
  • My passenger airbag system started intermittently flashing "service airbag". Took it to the local dealer, they said "Oh, we found a fork under the seat, this is your problem". Needless to say this was not the problem. Now the light is on all of the time and the dealer told us the car is now past 60k miles and GM is not responsible.

    This car has had major work to the steering column, the transmission replaced and numerous brake system problems.

    Warning to all GM customers, the manufacturer will not help you!

  • I have a 2008 Enclave with 110000 miles and tomorrow it is going in to the dealership for the 2nd time with the same symptoms (service stabilitrack, traction control, reduced engine power). Feb 2012 they replaced throttle body when the same warnings were flashing. Difference now is, of course, I am no longer under warrenty. I have heard there is a known problem that will cause this and it has to do with the 3.6L engines and is a $3-4K repair that GM is refusing to recognize on these engines. Any advice or help would be appreciated.
  • Please see my post #128. Were you getting stabilitrak/traction control warnings? I had my local mechanic look at my 2008 Enclave and he found the brown fluid just as you described. He cleaned it out, but the warnings began immediately again. I had the same problem almost a year ago and dealership replaced throttle body. I am going to dealership tomorrow to try to have the problem diagnosed, but I was told by my local mechanic it is a known problem with the 3.6L engines. Have you gotten any resolution with your Enclave?
  • My engine light problem actually turned out to be a bad wire connection in the under seat wiring harness. Everytime they checked it out with the seats out the light wouldn't go on..install the seats and console again and pretty soon the light would come back on. The last time (6th try) I didn't even get it off the lot before it came on again. Finally they checked each wire individually in the harness and one was not completely solderd. so far so good but it sounds like these "08's are one problem after another and They have gotten so expensive we might as well buy a Suburban or Cadillac crossover for the same price.

    We're glad to hear that they got to the bottom of it, mcduffer! Keep us posted if anything should arise by emailing (include your case number or the last 8 of your VIN with a description of what's going on). Hopefully this won't have to happen, but we're here if you have additional problems.

  • I do have a response and I have emailed you @ the address you provided. I am told that I need to have the PCV hose valve cover and seal replaced and that this is a re-designed part. This is the issue I was speaking of in my original post that this problem is due to a design flaw in the 3.6 engine. It is my understanding that Enclaves, Acadias, Envoys and a Cadillac model (do not recall which one) have this engine and will develope this problem at some point. I will await your response to my email and will let others on this forum know if GM is standing behind their product or excusing themselves from responsibility.

    GMC does not want to do a recall and fix the problem. I also had the same problem on my 2008 except the brake warning light was also on at the same time. Dealer said it was a faulty part. FAULTY meaning GMC put a bad part in the cars and we the consumer are stuck paying full retail for the part along with a service charge over $500 dollar cost to fix the mistake (master brake cylinder). My dealer told me the car was a risk to drive and I needed to repair it asap or do not drive it. They assured me that GMC would be sent the faulty part for inspection (wrong). Nobody knows where the part went. Really? I could have taken it and did my own investigation??
  • I have a 2008 Buick Enclave having the same warnings as it seems the other 08s are having. It literally start shutting my vehicle down to the point I had to have it towed to the dealership. Just received a call today from the dealer saying that is was bad wiring (shortage) in the throttle body. But also they are getting a lot of codes off of the transmission, which indicates the transmission is about to go out. Which also seems to be a serious issue with the 08s. And the front struts are going bad and need to be replaced. I'm not understanding why GM will not put a recall out on all of these issues that apparently seem to be design flaws. You pay $40,000 for a vehicle, you don't expect to have to shell out $5k or more at the 3-5 year mark on the vehicle. Really disappointed in Buick.

    Had the same warning light, the dealer fix it and as soon as I drove off the lot the break warning light came on. That's when they told me not to drive the car, after inspection they said I needed a new brake master cylinder. Faulty wiring is what I suspected. GM and the dealer assured me they would be sent the part for inspection, I was dumb enough to believe so I didn't take the part. Sure enough they went back and forth saying they both do not have it. Calls never returned.
    Stuck with big $$$.
  • I cannot understand how GM can justify not reacting to these issues. I am now stuck with almost $1000 repair to replace the valve cover and seal and intake tube. This is a re-designed part because the original part was flawed and GM takes no responsibility. I already had the throttle body replaced last year under warranty, thankfully, for the same warnings. I was getting emails from a GM Customer Service Rep but when I asked direct questions about these problems listed on the forums, her response was "GM does not consider online forums to be a valid source of information"!!! I would recommend watching for the class action lawsuit if GM does not issue a recall. They say it's not a "safety" concern, so no recall. But I would say when my traction control is jerking on and off and my engine power reduces to 30-40 mph, that's a safety concern for me. Not to mention I live where it snows and traction control would be a good thing to have operational. Way to go, GM, you have lost this customer for life.
  • I shared the same safety concern with my dealer over a year ago about my vehicle losing acceleration, especially when I was getting onto the interstate and cars/18wheelers coming at 70-80mph and my vehicle would stall around 30-40mph. They told me then they couldn't re-create the issue. I no longer have warranty and I now have to pay cash for the very evident issue.

  • My service airbag light turned out to be loose wire in the wiring harness under the seat. When they removed the seats the light went out. Put the seats and console back in and the light came back on after driving for a short period. It took 6 tries before they found it. Either that or they took the bulb out.

    How many miles are on the '08's with throttle body and transmission problems? Leaving for 2 weeks in California on Thursday and now you have me scared to drive!
  • Having the same issues with my 2008 AWD CXL. It happens if I pass someone and then back off. Like clock work when I enter the freeway I notice the traction light comes on then park and brake light comes on air bag service light stabilitrack/traction with engine light. Few miles down road shuts down to 20 mph on interstate traffic. Set along road watching others stare while they go by. Each time I set approx 30 minutes with engine off once I start it will take off and I can get it back to normal speed, until next time. Lose air pressure on one tire even after I put on brand new tires. I need to fix the problem of the engine powering down its cold in MN and setting along the road it's miserable. Did I mention my AC stopped working last fall. But I love this car I wanted to trade for new one. But concerned reading the complaints Last 8 on VIN 8J162943

    I checked your VIN and see that you're outside of the main warranties (bumper to bumper and powertrain) by time at this point. I'm sorry about this, especially given your current concerns. Do you have a game plan about getting this checked into?

    Sarah, GM Customer Service
  • I will no doubt trade it before I have other issues. I sure was hoping for a new one, but I will have to check into Ford or Chrysler. Too bad I bragged to others about the car, but that was before it hit 110,00 miles. But I still really like the ride and look.
  • Sorry..just read your question. I have about 130,000 miles.all problems began around 56,000 miles for me. Water pump replaced, rack & pinion replaced; leaking roof; emissions valve throttle body, transmission going bad and they say front struts are starting to lock up
  • That's what's sad...I really love my vehicle and have don't really want another type of vehicle..but the mechanical failures are monstrous..don't know if I could get a decent trade in with all these issue

    We're having the same issue... :( . You would think GM would do something about this...BUT. This is truly disturbing...I shouldn't have to pay for this. My Grand-Father drove a GM, my father still drives a GM and after today I may just end this tradition. This is like buying a luxury home and the builder tells you: "Congratulations again...its been 5 yrs. since your purchase with us. If you are experiencing foundation problems right is perfectly normal. BUT, don't worry your insurance should have your back...HOPEFULLY :) . Thx again for chosing Dye Anal Builders"

    What's so sad about this is; we chose American made over German. Boy I feel stupid. After this, driving on a GM dealers lot may be very slim in our future. Still an American cunsumer and big support...just not a big fan of GM.

    I purchased a 2012 Buick Enclave on Jan. 26, 2013. Feb. 15th, 2013 a warning popped up in the DIC stating that the Traction Control system needed servicing and the ABS system was off. The car is sluggish and won’t accelerate correctly. We contacted OnStar reported the problem and had an appointment to bring the car to the service department at Sunrise GMC in Collierville, Tn. They said bring it in the next day which was a Saturday and they would have someone available to look at it. On Saturday I took the car in and 2 ½ hours later was told the person that needs to service it was not there because it was a Saturday. I was offered a rental (which was not an enclave of course) and told they would call me Monday. I can’t believe I can’t make it three weeks without any problems. This is completely unsatisfactory. Now it’s Monday and they tell me they are waiting on two sensors to be replaced and it will possibly be Tuesday when the car is ready. I had to call them at 4:30pm Monday to find this out. I am looking into the Lemon laws for the state of Tn. in order to protect myself. GM needs to get some quality control procedures in place and crack the whip on their dealers. These cars are cost too much to break down this quickly.

  • I had the same problem and I was told the abs brake warning light was a different issue needing a new brake master cylinder so I had to pay for that repair. My concern is that everyone is also getting the same warning lights which makes be believe it's all related not a separate issue. Just a way to be charged for another repair. I got taken. To top it off the old part went missing, they knew I was about to get a second opinion. Recall needs to happen asap.

    I already sent a email to you before I posted here. It was sent Monday 2/18 with the subject line 2012 Buick Enclave. It has the information you requested.
  • mbf1mbf1 Posts: 5
    I agree. They changed the two sensors and that did not work so now they are replacing a control unit. I will keep everyone posted.
