Buick Lucerne Vibration Problems

wayne55wayne55 Posts: 7
I purchased an 06 CXL in mid June. There is currently 5400 miles on it. The car is a dream with the exception of an annoying vibration between 50 and 63 mph. The dealer has put 3 different sets of wheels and tires on this car and the problem is still there. Has anybody else had this problem and know what the fix might be?

    What brands were the tires? I'm always partial to Michelins for round-rolling, balanced tires that stay balanced.

    The fact they're tried several other wheels from other cars makes it sound like something else. Did the other cars have a vibration when the wheels, yours or the originals, were on that vehicle.

    I'd say it's a driveshaft or something. Call in the factory rep or try a different dealer.

    Yes you are right. I prefer Michelins as well. The factory tire on this car is Continental. I am not sure about the others cars. I'll ask. I am 1 hour from my dealer nad 2 hours to the next dealer. I live way up North. Maybe when i get back to California I will see a dealer there. Thanks for your input.

    A driveshaft in a FWD Lucerne?
  • imidazol97imidazol97 Crossroads of America: I70 & I75Posts: 18,190
    Yeah. Whatever the shafts are called with the CV joints in them these days.

    Yeah, I was hoping my new Lucerne CXL came with Michelins, but it came with Continentals. They're fine, though. Love the car!
  • I just purchased an '06 CXL and I'm having the same trouble with tire vibration at highway speed. I also notice it feeling "bumpy" at slower speeds. Seems like the tires pick up every little road imperfection. Took it to the dealer last night - rebalanced the front tires - actually feels worse. The vibration is now noticeable at 40mph and up. Have you had any luck getting this resolved?

    Did they use the Hunter 9700 Road Force balancer that corrects for uneven rolling heights in the tires?

    Another possibility is checking alignment on all four wheels and putting it dead on center of each; none of this "It's within the tolerance range so we're not going to change it." My 03 LeSabre had toe in error on rear wheels for 6000 miles before dealer did that after rebalancing wheels twice and driving the car on a nicely repaved asphalt road that was smooth with a vibration analyzer hooked up tot he seat and to the steering column.

    What brand of tires does the problem car have on it? Michelins are the best for quality and roundness.
  • It came with Continentals on it. I've never had those - prefer Michelins also. They told us that Buick wrote the specs for this particular tire.

    I'm not sure what they used for balancing equipment --I will be calling the dealer again shortly so I will be sure to find out. Thanks for your help.

    GM always writes the specs for tires. GM has basically the same specs for all tires for balance, uniformity, etc. What is different, depending on the application, is ride, rolling resistance, life, etc. These are tuned using vehicles at the proving grounds. A Corvette has different requirements than the Lucerne for example.

    Michelin and Continental would have to meet the same specs for the Lucerne.
  • Understood -- the actual tire is not really in question (although I would choose Michelin any day) it is the vibration that's causing me problems.
  • 62vetteefp62vetteefp Posts: 6,048
    The tire could still be the issue, do not get me wrong. GM has quality specs but parts may not always meet them. Best thing for your dealer to do is have you drive another Lucerne and you say this car does not have the same problem. Then switch the tires from car to car and redrive and see what happens.
  • Requesting to drive another Lucerne was actually going to be one of my next courses of action. I didn't really think about switching the tires and driving mine again. I'm actually waiting for the service manager to call me back so, we'll see what happens. Thanks

    If your dealer used a Hunter 9700 ask what the force amounts (they use pounds) were. My Michelins were under 10 pounds other than one that was 12. The maximum was something in th middle teens.

    As the tires rolled up toward 25 K miles they seemed to get more even. I suspect the crush in the sidewalls evens out as the tires roll that many miles.

    Early on in this GM was replacing tires on problem cars with Michelins. That was about the time I bought my LeSabre in Dec 02. That's why I'd still suggest Michelins. If they have a car on the lot they're willing to switch wheels with yours for a test, choose one that has Michelins.

    That's my opinion after owning Michelins since 1967.
  • I have driven a CXL and A CXS. While each felt a little different, I did notice that both picked up too many vibrations over some surfaces. My old Taurus wagon did a better job on the same surfaces. Perhaps it's the lower profile tires 55 and 50. I am interested in the Lucerne because of its interior comfort, but I want to drive again before buying. I wonder if the the base model with 60 series tires is smoother, albeit less sporty.
  • 62vetteefp62vetteefp Posts: 6,048
    Not sure I understand your question but the CXL has less "sporty" handling than the CXS which means that usually the CXL will have better impact harshsness and a more comfortable ride. One Caveat here is the new magnaride suspension on the CXS which is amazing the way it lets the car handle and a comfrotable ride.

    One note, my neighbor just bought a CXL/V8 and he loves the ride. He just got out of a SRX and is a lead foot but the car is making him very happy.
  • I bought the CX and am really glad that I did. I test drove both the CX and CXL more than once.

    It became clear to me that the CX was the kind of ride I
    prefer as it had the perfect balance between too firm and too soft. It better isolates you from road bumps and
    is a pleasure to drive. The CX has 16 inch tires that compliment this type of suspension. Buick calls this "Premium-Ride". I think of it as providing a "Luxury" ride for less than $ 26,000 MSRP.

    The "sportier" CXL does not give a harsh ride. It gives a slightly firmer ride and more road feel,with it's 17 inch tires and re-calibrated struts. Buick calls this "Ride and Handling." CXL offers more control so one can take exit ramps faster and practice accident avoidance maneuvers more often!

    Leather is not available in CX but that is ok with me because I hate leather.( I know some must have it)

    Leather cost about$1,000 more,(Hidden in the cost of CXL) Leather is hot in Summer and feels cold in Winter. Car makers must agree because options are readily available.

    Another $500 can be spent on heated seats to fix the cold Winter problem and another $500 can be spent on heated/cooled seats to fix the hot Summer problem! OR, just take the cloth seats that come with CX.

    Cloth is best described as neutral, not hot in in the Summer nor cold in Winter.

    I loaded my car with the 3 major option packages Lots of toys for less than $2200 additional. Dual-Zone auto climate control,theft alarm, "Rain-sense wipers etc.etc. add to the convience.

    Each of us have an opinion of what is the "best" ride. Some will loudly dissagre because they know what they like, I'm glad I chose Lucerne CX over the Toyata Avalon and Hyundai Azera. Now with 5 year 100,000 mile warranty it's even better.

    This sounds like the tires have a flat spot from either shipping or storage on the dealer's lot. (The key to this diagnosis was that you could feel it at low speed.)

    Replacing the tires with anything that hasn't been mounted before will probably fix the problem.
  • imidazol97imidazol97 Crossroads of America: I70 & I75Posts: 18,190
    Doesn't that flatspotting smooth out after driving and warming up?

    I noticed my dealer drove my 03 Buick before rebalancing and that's in the TSB for the use of Hunter 9700 troubleshooting the out-of-round rolling.

    Too, my Michelin Symmetrys seemed to become smoother after 15000K or so. Do they tires "relax" or become softer and become more even in their crush around the circumference from the factory as they're used?

    I'm afraid that GM hasn't rid its full-size platform of the susceptibility to tire roundness. I've experienced the same issue on my '02 Bonneville and I still live with it, though to mitigated by expensive tires.

    Those interested can follow my saga, going through 3 tire brands, starting here.

    Read some of the tire posts on the 300C page. That car (I own one) comes with the Conti Touring. Lots of complaints of noise, handling, alignment drifting as well as early wearout. Mine drives like the have flat spots for the first 2 -3 miles, regardless of outside temperature. Can't wait till I can justify replacing them.....
  • I have spent the last few weeks arguing with Continental about their tire (Touring) and the finally admitted that the tire has a vibration in it. They sent my dealer 4 new ones (not Touring) and I traded them in immediately for Michelins. It is an entirely different car (better). No road noise, no vibrations at any speed.
  • imidazol97imidazol97 Crossroads of America: I70 & I75Posts: 18,190
    Which Michelins did you put on?

    You reinforce my tenet that the quality of the tire makes a difference and Michelin usually has better quality for the rolling characteristic.
  • evandroevandro Posts: 1,108
    Which Michelins did you put on?

    FWIW, I put MXV4+ on my Bonneville, but its size is pretty rare: 235/55R17.
  • I am having the same problems with my Lucerne and thought it might be the tires. I just bought my car two weeks ago and had to have a new battery installed within the first two days. I also had to have the intermediate shaft replaced in the steering wheel as well as a shim, supposedly to stop the drifting to the right. I would like to know if anyone has heard noises coming from the fuel pump. Mine sounds like air escaping accompanied by a fuel line noise.
  • Here's the latest on the vibration issue my '06 Lucerne has been having. We have taken it to the dealer two more times - they rotated and rebalanced all of the tires. We took it on vacation and it rode horribly. We just took it back again, they let me drive another one to confirm that it does have a problem (which I already knew it did, they just are not interested in fixing it). They are trying to tell us now that it is a "drive line vibration" and they will need to contact GM to find out what to do about it. Anyone heard of this with a Lucerne? I really don't trust this service department!
  • 62vetteefp62vetteefp Posts: 6,048
    Very possible it is a driveline problem. Did they switch the tires/wheels with another car to see if the problem went away?
  • No. I practically begged them to fully check the tires and wheels but to my knowledge, the only thing they have done is balance and rotate. I noticed the vibration more and seemingly in the back of the car after they rotated --that's why I'm questioning driveline. They said rotating the tires just brought it out more but I'm not sure I understand why - shouldn't all four tires be the same?
  • 62vetteefp62vetteefp Posts: 6,048
    It is possible a different tire has different characteristics that would change the driveline vibration slightly. However I still would ask to try a known good set of tires/wheels on your car.
  • dmathews3dmathews3 Posts: 1,739
    I have test drove 2 Lucernes and neither one of them had the least bit of vibration as I have made a list of problems here and when the time comes to purchase my 07 you can bet I will go through it to make sure nothing is wrong.
  • evandroevandro Posts: 1,108
    My Bonneville was darn smooth when new too, but after a couple of thousand miles, the vibration started. Anyway, I told my whole saga about it below:

    Part 1
    Part 2
    Part 3
    Part 4
