Buick Lucerne Vibration Problems

    >started the engine, shifted to drive and ran the speed to 30 mph (the other front wheel was on the concrete and not turning) so the elevated wheel was doing 60. The left front, with or without the tire and wheel, gave a real good vibration. Repeating all this with the right side produced no vibration at all. Had to be the left side shaft or joints. By now all the service writers would suddenly have something urgent to do when I showed up so I went to an independent who replaced the assembly for $220

    You verified what someone else had already reported. Good for you. ANd I'm glad you were analytical enough in your procedure that you found the vibration. Many people don't realize that in a differential setup, one wheel free is turning twice the speed of the speedometer. So it can be very dangerous.

    I also would worry about hanging the wheel free, because the CV joint is flexing more than its usual amount. I would have supported the A-arm some. But I'm glad you found the problem.

    What I would do is submit a copy of the bill to the service manager, not the writers, the service manager. Along with the copy I"d list the times you were in and what you told them to check.

    I'd also submit the bill directly to Buick by certified mail. I would suspect $220 may show up in your mailbox as goodwill payment. I remember when I disassembled my 67 Mustang because it kept freezing up after a long drive. Ford paid me for the damaged piston and required new gaskets for rebuilding the motor. They did keep the damaged piston.

    I should have included in my explanation that I used a floor jack under the front suspension systems and that the axle and joints weren't hanging free, You're right, if they are hanging free you would be so far out of the usual running position that you could get vibrations from an assembly which does not have a problem.

    In my case the problem was the left inner CV joint and I was told that the joint itself wasn't available, that the whole assembly was the only way to go. The price for the assembly was $120 with $100 labor. Don't expect that at the dealer. I told the service writer at the dealer that I was sure of my diagnosis but he would only agree to check for vibrations, which was a repeat of what they had already done. At that point I decided to go elsewhere and was happily surprised with the estimate.

    >I used a floor jack

    Thank you. I feel safer for you.

    I still would hassle the dealership about a refund of cost.
  • I went to my local Buick dealer (Not where I bought my 06) with the invoice for the work I had done at the independent shop and. what do you know ! I'm assured that I will receive a check for the full amount in the next few days. Good for GM !!

    I have the same problem with my Lucerne, what size are the rubber washers, did you use one on each bolt, and did you put them on to the plate that the brake and gas pedal are mounted on? Any help would be appreciated.

    Sorry I didn't see this sooner-- I don't visit the forum much anymore since we got rid of our lemon. I'll go ahead and answer your question -- maybe it will help someone else.
    If you are having vibration and clunking problems with your Lucerne and no one seems to be able to fix it -- get rid of it! We had ours to the dealer 10 times for those problems, we had about 4 sets of tires, replaced half shaft in the steering, numerous tire rotations, road force balancing, etc. Also unrelated-- the driver's door handle fell off, the stereo blew up and the mechanism that controls the driver's seat and the driver's mirror went bad. This was over a period of 23 months -- we tried to work with the dealer to resolve and we tried to work with a GM troubleshooter to resolve but got nowhere and used lemon law as a last resort.

    The most important thing to do is take the car in to the dealer immediately when you notice the problem and make sure it is well documented - particularly mileage because they will charge you for usage even if you win. We were outside of the statute of limitations when our case got to hearing BUT because the problem started with low miles, our usage fee was nominal (we had over 40,000 on it by the time we got to hearing). If you are over a certain amount of miles when you start your case, they'll throw it out. Keep all documentation of any visits to the dealership and make sure they write on them what they did and the service bulletin # if they used one. I also made a spreadsheet with the date, reason for service, how long they had the car, what they did, and mileage each time it went in. This proved to be very helpful when it came time for hearing preparation. We hired an attorney but went through the BBB arbitration process (I think GM requires that). The attorney did a lot of the contact work with the BBB but you can definitely do this yourself. It is actually set up to be used by the consumer. Basically, the case is opened up online, you send in all of your documentation when they ask you to and then they decide if you have a case. If you do, they set up hearing at their office (we went downtown Pittsburgh because that's where I work). Our attorney was there, a volunteer arbiter from the BBB, and a GM rep was on conference call. I spoke for my husband and I because I was the most involved with the ordeal. The GM rep stated her case, I stated mine. The arbiter asked questions of both of us and then the GM rep was allowed to ask me a couple of questions. The arbiter has the option to drive the vehicle -- he did in our case. When we got back, we called the GM rep back and had closing comments. It took almost two weeks for the arbiter to make a decision but he ruled in our favor and GM had to reimburse us for the full amount that we paid for the vehicle. We did not get attorney fees because the BBB feels that an attorney is not necessary to use their system. It is not necessary if you are well prepared on your own-- in our case, I could have done it myself-- our attorney was more hinderance than help most of the time.

    My parents just bought a 2010 CXL (much to my chagrin) but we'll see if it's any better than our 2006.

    Good luck to anyone who opts to go lemon law -- it can be done! I'll be glad to give further advice if anyone needs it.

    Do you have the address of Buick in Detroit and name of the person with whom you spoke? Was your car a V6 or V8. I have a V8.

    Does anyone know the TSB for bad engine mounts? I have seen a few posts regarding mis-designed engine mounts, but I cannot find a TSB about this. Dealer
    said they cannot find it either.

    Do you know the TSB for the bad engine mounts? I know you have a V6, but I wonder if it will apply to a V8 as well.

    well the dealer did find that I had 2 bad wheel bearing hub assemblies and 2 bad axles. This did help my vibration tremendously. However, I still have vibration on
    acceleration. The dealer did find that my engine mount "strap" was wrong and they adjusted that, but I still feel the vibration, maybe even more so now. I am not even
    sure why there is a "strap" on this car. Seems the mounts should auto-align the engine/xmission without some adjustable part. Well that's another top in itelf.....

    Can bad engine/xmission mounts cause the axles and bearings to go bad? I would think so since the flex would stress the axles and thus the bearings, but just trying to get another opinion. It seems very strange that 2 hub bearings and axles all go bad within 40K miles. I really think the mounts are bad. I assume this "strap" was incorrect since day 1 since I never had any work done on it until it was recently adjusted which leads to my next question.........if the "strap" was incorrect and my engine/xmission was flexing to much, can this wear out the dampening of the engine mount rubber? I would think so, but again I want another opinion. I think the dealer is checking the mounts and if they don't see a tear or leak, they assume the mount is good? Besides a visual tear or leak, how else can an engine/xmission mount be tested? I think maybe the dampening of the mounts is shot especially since the "strap" was not correct.

  • Not sure about the V8. I don't know the TSB for the bad engine mount (only 1 allegedly bad, the other good). My dealer finally came up with the REAL solution (limiting engine block rotation under acceleration), as described previously. That fix apparently kept the exhaust system from hitting the frame as I accelerated, otherwise passing engine vibration to the chassis and largely by-passing the vibration isolation feature of the engine mounts (i.e., rendering any engine mount problem moot). Still, I appreciated their replacing the defective engine mount, as it might have become the NEXT problem after the primary fix (tightening the engine block motion-limiting strap one notch).
  • My brake calipers on rear wheels rattle on road surfaces that have narrow joints, I figured this out by littley stepping on brake then rattle stops, anyone else have this problem
  • i am at wits end....first of august purchased a 2011 Buick Lucerne CXL..vehicle had vibration and shake in steering, driver side floor board and driver seat...driving on freeway vibration and shake get worse (can then feel it on passenger side)....the faster the car is driven the more apparent vibration and shake has been back to GM dealer at least 6 times now...tire balance and rotation has not helped....last straw was yesterday...dealership finally said that GM Rep told them "common problem, customer has to learn to live with it, NO FIX"....WTH??? so am I stuck with a car I can not drive on the freeway? ummm.....I don't think so...even tho my car has 38000

    i should add...the dealership agreed to fix the problem if we purchased the car...they have changed two of the tires and wanted us to buy 2 more...BS...the dealership has not delivered what they promised, thus broke the we have decided to turn this whole matter over to a Lemon Law attorney....will know more sometime Monday...
