When the Bridgestone dealer RoadForce balanced, did they tell you the amount of error in the tires? Example, my Michelins all checked below 10 units except one was 12. The dealer said the ram-tested tires GM shipped for replacements at the tie the frame stiffness was becoming a factor showing the bad tire construction were showing up to 18 or a number like that. IOW, a good tire fixes the problem.
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.

I don't know, but I will go back and have them do it again and tell me the info. What is the accepted road force balance value for CXS so it will not vibrate??? I am almost certain it is the tires as it has improved by some degrees when I had various balances and drive for a short while although never vibrationless. I really like the car but this vibration I will not accect and I am certainly not about to spend $1K to get the proper tires.

I just setup an appt for tomorrow at 10am. I requested to have a pre and post printout of each tire results. I just need to know what is a "good tire" for the Lucernce in terms of the results.

Well my vibration issue driving at speeds higher than 40MPH was fixed. It turns out I had 2 bad tires and when the 2 new replacement tires came in, they replaced the 2 good tires with the 2 new tires leaving the 2 bad tires on the car. Anyway, once I got the 2 new tires
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.........

Have you tried checking the tire pressure? A tire installer inflated mine to 38 lbs. and after going over bumps it rang like a bell. I set the pressure back to 30 and no more ringing.

I just won my lemon law arbitration case for front end vibration on my '06 CXL. Still awaiting the settlement numbers from GM but it should be everything that I paid for the last 21 months, plus my original trade-in, downpayment, and TTL. They also have to pay your attorney fees if you use one (over and above your settlement). DO NOT use one of those lemon law attorneys that are advertised. They take a percentage of your settlement. GM requires you to go through the BBB Auto Line if you wish to pursue a lemon law case. You can do it yourself online if you want to. We had an attorney (whose only value was the day of the hearing), otherwise I spoon fed him everything - even definitions of the PA lemon law. I am extremely pleased with the way the BBB handled our case. If you want any more info. let me know. Good Luck!
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).

I would rather GM built this car as a rear wheel drive as I am more familiar with that concept, I have had only one vibration issue and that is on turns at low acceleration
otherwise car is quite smooth.car is cxl w/V6
#189 of 226 vibration on 06 CXL

I have an 06 cxl V6, the dealership has balanced the tires about 3-4 times, then finally put 4 new tires on, no luck, still vibrating, what to do?

Jul 21, 2009 (10:45 am)
Well, I just got and update, the dealership has determined that the car DOES infact have a PROBLEM, it needed BOTH FRONT AXLES! Tha bad thing is I had to call BUICK to get some help, they then called the dealership and set up the appointment! I hope this will solve all vibration problems!

how did you contact Buick? feel free to email me or respond here with the number and the rep to whom you spoke, do you know if Buick suggested the axles or they found it on their own merit? I had my tired changed and I still get a vibration on acceleration and on turns. Hitting bumps I feel a shuddering vibration and sometimes in the pedal almost like a tuning fork being hit. The dealers keep telling me nothing is wrong but something has to be loose under there. btw....is your issue resolved now?
