Buick Rainier Repairs



  • Hoping you all can help. I have an 06 with only 64,000 miles on it. In the past two weeks several things have started happening to it. In between second and third gear it starts to make a whinning noise, as well as when I stop it feels like someone is hitting me in the rear end. Took it to a shop (non dealer) and they could find nothing wrong with it, no codes etc. have not taken it to the dealer yet as we can not afford to many more repairs. Someone has mentioned the rear differentaial was locking up and possibly the transerfer case as well as the clutch plate? Does anyone know what the drive tran warrenty is on these? this car has been very well taking care of and now isn't worth what we owe on it! Feels like we stuck. Anyone have any luck getting gm to fix the issues?
  • I have had this car 3 years and loved it, up until about 2 months ago. I bought it used in 2009 at 59k and now have 141k on it and don't want to sell, but here is what is going on.

    Until recently, it worked like a dream but last month the All wheel drive failed and the transmission guy charged me $1700 and now the rear differential failed for another $900. Can't keep dumping money into this so I guess I must sell. Are GM cars no longer made to last? I really wanted to get this to 200k at least. If a GM employee is listening, please help as I have driven GM cars since my first one in 1993 and am about to give up!

  • just last week we had our rear air bags replaced after finding leaks. Now, they are not filling and releasing as needed and stuck very low. the pump is functionind (as checked by the accessory inflator). does anyone know if there is a sensor or something that needs to be recalibrated after installing new bags?
    thank you

    Have you been working with your dealership for these repairs, buickrainier1, or with an independent shop?

  • I bought My Ranier new in 2004. It has had nothing but problems since it hit about 50,000 miles. My heated seat over heated and almost started on fire, I have had to replace at least 4 wheel bearings, radiator problems, air shocks went bad, driver door lock switch had to be replaced because I couldn't close it (latch problem) and now my AWD is not working. I have sunk literally thousands of dollars into this piece of crap and things just keep going wrong. There is a reason GM is in financial trouble. In spring I will be looking at new Fords. We have always been a Buick family but I have had enough. The people at GM pretend they care, but they don't. What's even worse is the problems I have had with this thing is that most of the problems are just plain dangerous.
    I am on vacation this week and today I have to take my truck to a dealer I have never been to in the area I am vacationing in so I don't keep getting stuck in the snow! Can't wait to see what they are going to hit me for this. Nope, Never again and I tell everyone I know, and plenty of people I don't know NEVER buy GM. My mom who has always had Chevy's even switched to Ford. GM... You are doing a wonderful job of putting yourselves out of business.

    Trying to replace an oil pump on a 2006 2-wheel drive Rainier with a 5.3l engine and cannot get the oil pan off. Removed one cross member towards the rear of the pan and all bolts. Pan lowered a few inches easily but now sits on a cross member and the steering gear cross member. Pan will not move forward enough to come out. Repair manuals do not say to remove the steering gear cross member or the second cross member (second steel cross member appears to be welded in place). Anybody know if I need to disconnect the engine mounting bolts and raise the engine to get this pan out? Can I work it out with removal of only the steering gear?

    I'm back again. I check periodically in hopes someone has resolved one of my '04 Rainier's many problems. No such luck. Our mechanic is a good guy and very honest. He's overwhelmed with business right now (a good thing, but...) but always does right by us. Our Rainier's problems have been literally prioritized, there's so many. We had an issue in early December with the other front axle due to the differential. Once that was fixed (very very costly but less than the dealer) we decided to address the occasionally working cluster panel. We had saved up to replace it but the axle/differential repair had bumped itself up to #1. Apparently when you get a refurbished one some of the dealers balk at calibrating the mileage. Now that it has been replaced we're getting error messages and have to diagnose those. This is ridiculous and embarrassing. I've seen all of these GM Representatives on here ceremoniously telling owners they will help to resolve the issue. BS. Once they hear you're over the 100K mark they don't care. Who knows, it sounds as if they don't prior to the 100K mark either! But come on Buick, stand behind your product. Do the right thing and help us - YOU are the common denominator. We've already invested a great deal of money and time. We can't dump the vehicles in the market because they don't stay running healthy long enough to do so. I love mine when it's running, but can't afford to keep doing this.

    MOM, the instrument cluster can be removed with just a phillips screwdriver and a7 or 8 mm socket in less than 20 minutes. The company that GM uses to rebuild them is United Radio in Syracuse NY. It is $175 to have it rebuilt, and mine took 5 days from removal to reinstallation.

    That is less than HALF what it would cost even to have an independant shop do it.

    Hope this helps.
  • It sounds like I am having the same issue. Did you ever find out what was wrong?

    I purchased my 2004 Buick new and paid the horrible price for it that everyone else did. Being a single mom, I wanted something reliable. My uncle was a GM dealer for 50 years until his death. He insisted that all of the ladies in his family drive Buick's because they WERE so reliable. Not only is this the first Buick I have paid full price for, it has been the worst one I have ever owned. GM really messed themselves up with this and have lost a lot of long time customers for failure to resolve all of the issues that exist with this vehicle. When it hit 60,000 miles everything started going wrong with it. It is currently in the shop and the repair man is having trouble identifying the problem. Every time I put it in the shop, they have to keep it for a month or more to try and fix the problem. I have had the following repairs done:
    Instrument cluster replaced
    Air Conditioner replaced twice
    Transfer Case
    Rear Differential
    Suspension Air Bags
    Wiper motor
    I am having the problem with the binding when I turn. I took it to the dealership and they told me that crow hopping was normal. Please . . . that is not normal. Now I have taken it somewhere else because the dealer obviously cannot fix this car. Every time they "fix" it, a whole new set of problems seem to develop. I asked them to put new brakes on my car and every time they gave me the little sheet back showing my brakes were fine (green check box) until I had to have the rotors replaced. It cost me an extra 300 bucks because they did not want to do their job.

    At present, this trip to the shop is up to $2600.00 and they do not have it fixed yet. The sad part about it, when I put it on Craig's List to get rid of this money pit, I will be lucky to get $5000.00 for it. It has 107,000 and the transfer case and differential problems have happened within the last 10,000 miles. Then of course there is the ever present oil leak. Luckily, both of my boys have vehicles because I have been totally dependent on them to get me to work over the past two years. My car has been in the shop and parked in my garage for the majority of the past two years.

    Having owned Buick's for the past 30 years, I will never purchase another one. My son has a 98 Ford Ranger that has been the most reliable vehicle I have ever seen. The great thing about it, it is super easy to fix. Takes a trip to Auto Zone and thirty minutes of your time. You can pretty much fix anything on it.

    GM you should be ashamed of yourselves for charging such a huge price for a piece of crap. You should suck it up and refund the owner's of these vehicles part of the purchase price back for the countless hours they have spent trying to get these vehicles repaired. You continue to refuse to take responsibility for this mess. All of the ladies in my family know about all of the problems I have had. Since my uncle is now deceased, they are all turning to Ford, Toyota and Honda and other vehicle makers. I cannot wait to rid myself of this money pit. I traded in a Buick Rendezvous that had 218,000. I had minimal problems with that vehicle. I wish every day that I had my Rendezvous back.

    No offense, but NO ONE from GM gives a hoot about what we're going through with the Buick Rainier. Once they hear that you are out of warranty (and seriously who has one that isn't at this point???) they graciously say they are sorry about your luck and wish you well with your predicament. I just got mine back from the shop, it was there from December until May. There are STILL problems which we didn't repair because we'd hit our wall of expenditures on this vehicle. You should be ASHAMED of the fact you haven't RESOLVED this with customers and haven't declared the Lemon Law.
  • Maybe we should all contact the NTSBA and request a recall on this vehicle
  • With all these problems I'm surprised that no one has contacted the NHTSA.
  • found out that U must have the proper size TIRES on this car or u will have clanking, hard turning with clanking, and more. Found this out as I bought a size down cause they where cheaper and started to have problems. Went back to 245-65-R17 and my problems went away. I can even pull my camper better now also. Hard to believe but so true. Hope this helps with some who have not damaged their cars as yet.
  • I did all that and had tccm put in and still the hard clunking noise even while going straight not just on turns.
  • cooterbfdcooterbfd Posts: 2,770
    Also, low tire presssure will cause this.
  • Already had it checked and it was the ring and pinion gears went bad with 83,000 miles on it, bought it with 72,347 miles on it.
  • Took it to the dealer and they put transfer case fluid in it and told me to drive 100 miles left and right until plates seperate when that didn't work they changed the tccm which had already destroyed the front diff cause they didn't know what he problem was in the first place.

    I see that you've been to the dealership for a past repair. I hope they were able to correct the problems you were having with your vehicle. If there's anything we can look into for you please don't hesitate to let us know.

  • No help yet, can't get car to dealership because the front diff is so busted up from them not fixing it the first time I brought it in.
  • Had problems with this vehicle ever since it was purchased and was always told nothing is wrong with it and now tht the warranty is up no one wants to help, so sad that after financing this vehicle for $19,000 and a year later I would have this much trouble with it.
  • Next time I will know better, thanks for your response. To my txt.

  • I purchased my 05 Rainier in November of 2012, with 60000 Miles on it. Since then I have had to replace the engine (at 68000 Miles and a cost of $4k to do myself), I am having issues while turning at low speeds, The heater control module went out ($100 repair) and now, the security light comes on at random and I can't even start the vehicle.
    When my engine blew, I contacted the GM dealership where I purchased it (Owned by my uncle), and he put me in contact with their factory rep. He said "sorry about your luck". I contacted my own factory rep (Yes I have one) and was told the same thing. REALLY????? Never mind that this vehicle has such low mileage and the engine is BLOWN. I work for one of GM's largest customers and suppliers. You can't do anything for me?? Sorry about my luck??
    It's a good thing I am a mechanic and can make these repairs myself.
  • I have a 2005 Buick Rainier with 93,000 miles that has all kinds of problems! My AWD doesn't work? The rear slides when it's wet and I'm turning and, I absolutely cannot drive it when there's snow on the ground. Last winter it was snowing and I was making a left turn very slowly. The car just started sliding and I landed in a ditch. A car coming in the opposite direction came inches from hitting me! Thank goodness I didn't get hit, hurt another person or myself and my car didn't get damaged! Also, when I'm backing up. The rear of the car makes this grinding noise? Maybe it's also the AWD? I'm not sure?I've had my car checked out by 4 different mechanics and they all say they can't find anything wrong? I take that back. One said my wheels just aren't turning at the same time, but that's normal and there's nothing to worry about but...there is something wrong with it. A major problem when myself and others can be killed, I can't drive it in the snow or rainy weather's my only car! My gas gauge and speedometer also doesn't work! I've had 2 tickets due to the speedometer. I gauge my speed by other cars. I write down my mileage and how many gallons I put in my car, but I've still ran out of gas several times. How inconvenient, embarrassing and risky getting in strangers cars to go get gas! Here's the break down of the problems with my piece of junk Rainier.

    - AWD doesn't work.
    - Rear grinding noise when turning to back-up.
    - Gas gauge doesn't work.
    - Speedometer doesn't work.

    Please help me and reply back on what I need to do to repair these problems. Thank you in advance for you help.
  • Your issue with turning at low speed is the transfer case control module, I had the same issue and after they put transfer case fluid in and it didn't work they changed the TCCM and it worked fine but it was to late for my front differential it destroyed it, so make sure they change your TCCM.
