I strayed from Michelin, swayed by rave reviews, and learned a lesson. Sure they are quiet and have good traction, but I am not happy with the wear so far and they do vibrate more than Michelins that I had on the same car. They also have more normal bulges in the sidewalls that I am not happy with. I have about 20K on them.
As far as the engine noise, I honestly can say it is not all that noticeable. I have owned several big FWD Buicks an Olds, and this is the smoothest and most quiet 3800 by a long shot so far.
I do like the wheel design Buick chose for the 16" CX.
If Lesabre and Park Avenue drivers start trading in their cars for the Lucerne, and the Lucerne has problems such as vibration, then owners may be turned off.
Since I like GM and am loyal, I hope that the Lucernes with vibrations are rare, and that there are many satisfied owners out there that don't write into this forum because they don't have anything to gripe about.
Anyway, I am thankful that mine does not vibrate at all. I gave it the most thourough test drive I have ever given a car before I got it.
Up to that point, GM was at a total loss as to the cause so they were no help. But thanks to my dealer's persistence, they were able to correct it.

GM was contacted and their response was that this was a 'normal characteristic of the vehicle" and asked me to 'accept the diagnosis given'. I am not satisfied after paying over $38,000.00 and expect GM to correct the problem. I have owned several Buicks and other GM products over the past 40 years have never encountered this before.
I have submitted a complaint to the Canadian Motor Vehicle Arbitration Board in hope that I will take into consideration my complaint from day one, that GM has been aware of this problem for some time (according to messages provided above), and that I was not informed of this possible design flaw.

In my opinion the Firestone/Bridgestone tire people have a vested interest in not trying to replace tires if the best new tire is going to have a substantial amount of RoadForce out-of-roundness.
Others have mentioned a change in a motor/transmission mount affected the vibration they were feeling on Lucernes.
What has happened is the moving parts on the wheels that hold the wheels in place have gotten lighter. This means less mass to hold the tire in place as it wants to move up and down due to the out-of-roundness. The stiffer chasses also transmit the feel more. This has shown the poor tire construction of some companies.

actually replacing the 2 bad tires, smooth!!! However, there is a another issue. I couldn't tell due to the bad tires, but when I go over bumps, there is some sort of resonating vibration for about 1.5sec or so after the bump. I think it resembles a tuning fork being being struck against something. Since I needed my car, I have setup an appt with the dealer to test drive another CXS to see how it handles. I wonder how good the MRC on this car was designed or if mine actually has some issue. A car should not wobble/resonate after going over a bump. I would expect a nice smooth ride since it supposedly adjusts many many time per sec.
Anyone else epxericence this feeling in their CXS??? The CXL does not drive like this as I have driven those a couple times. My tires were so bad I didn't notice this. At least I can drive on the highway now without vibration except when I hit a decent size bump. Then wobble shake.........
BTW - over the last 21 months, I have had 3 sets of tires, two RoadForce balances, numerous balancing and alignment attempts, steering half shaft, rotors turned (20K mi.), rotors replaced (40K mi), new stereo (CD quit working), new seat module (memory seat went haywire), and new driver side mirror (memory went haywire).
otherwise car is quite smooth.car is cxl w/V6
What brand of tires and what model did they get in the past? Michelin?
I assume these are ramp tested under load for quality and are being sent out for the dealer to road force balance and install?
The description of a resonance vibration after an initial impact by one poster here sounds like it might be a motor or transmission mount allowing a little movement in response to the impact on one wheel and that movement is continuing as it deteriorates instead of being dampened quickly.
Same resonating could come from wheels, axles, and tires invoking a movement and then the chassis and wheel continuing the resonance.

Have the tires rotated front to rear and rear to front. If the vibration disappears in the steering wheel, the imbalance is in one of the tires or wheels now on the rear end (a wheel could be bent).
If the vibration varies with engine speed, then it has nothing to do with the wheels or tires. There was a TSB that discussed a fuel line causing a vibration in the pedals and floorboard in the Lucerne. Make sure the dealer has performed the modifications in that TSB.
Keep the Michelins, check them for runout, get them rebalanced, and get a wheel alignment to take care of the pull.

>the dealer and GM would not admit
If they changed tires to Michelins for you it sounded like they were admitting there was something that not perfect? Right?
I'd suggest going and enjoying your car now that the problem has been fixed.

Clunking in steering is also a problem. Attempt at repair was also a failure. I'm 57 years old and have owned several vehicles. This is by far the worst riding vehicle that I've ever owned including those old clunkers from when I was a kid.
I do believe that the axles need to be replaced but can't convince anyone from Buick to do the work. BTY what will happen if this is not fixed? Is this dangerous?
