My 2011 Lacrosse has a horrible vibration as well, so much so that my pants dance around by legs. It has been rebalanced 3 times, road force balanced once, and had the tires replaced at 6000 miles to no avail. The vibration is so noticeable that I cannot enjoy anything about this car. The other car in the household is a 2011 Hyundai Sonata which has a superior ride to this Buick. The GMC Acadia which was given to me as a loaner while mine was in the shop has a far superior ride as well. I am so ashamed that I decided to give GM another try after 20 years with Toyota. I can't believe Buick has made the Lacrosse a flagship car. What a joke. Never will I ever own another GM and I will continue to write and tell everyone what a horrible car this is.

Just to be fair, have you read the reports by me and other very satisfied owners of the 2011 LaCrosse that include praising the ride experience we have had? I'm sorry you have had problems with your ride. I would think if it is as horrible as you report, GM/Buick would find a means to correct the problem or make you a happy camper otherwise. There are warranty solutions. I'm sure GM Customer Service will pipe in here to get your history. Let's see if they can help you out. My CXS is by no means a "horrible car".

There are many, many things that can cause vibrations other than the tires. I would get a regional rep involved to help figure it out. You could have a bad CV joint, and torque converter issue, bad strut, etc. I am sure they will figure it out if you are persistent enough.
Yes it is a pain the rear, but unfortunately it does happen. I wish you the best.

I am truly sorry to hear about the vibration you've described, and we would be happy to get a Service Request established with us so we could hopefully move towards resolving this with you and your dealership. If you are interested in pursuing this, please send us more information in an email, including your name/Edmunds username, phone and address, the last 8 of your VIN and current mileage, and the name of your involved dealership. My coworker Christina, who answers inbound emails from the Edmunds forum, will advise you as to the next step(s) at that point.

Nice of ;;you to input Sarah. I think you may be wrong on the time frame, but I no longer have owners manual to check for sure. I know tires are completely covered, except if you damage, until around 12K. Also to the one with problem, Have the wheels been removed and replaced for any reason?
Just having a rotation done even? Impact wrenches are the killer of rotors, or more correctly, "Not properly torqueing the wheel nuts." Metal is hard, but not perfectly hard. Those forces applied at the wheel nut spread through the entire assembly with time and result in the warpage that you feel when you brake if not properly torqued. It is not only the rotor that is effected, but the hub that the other end of those studs start in and the wheel itself. I have no data as to the relative hardness of the included components but it would seem the aluminum wheel might be the softest. And if the rotor was extremely hard then the pads might not be able to grab it sufficiently.

I posted a reply before I read this one. Sounds like you are on the right track. I had such happen because of tire rotation. When I returned to complain, the manager asserted they always hand torqued. I came at the correct moment because just the other side of the glass a mechanic was mounting wheels with an impact wrench. I got new rotors & drums. I had receipts where they were new less than 5K miles earlier and I was not accepting they true, turn my new ones. Those were steel wheels. Today, with the wider tires and aluminum wheels I'd push for them too!

The Lacrosse was a replacement the Malibu. Would you take another Malibu after such life threatening experiences? And if they can't fix the current one why would you think better of another?
This is not a reflection on the dealer because I've learned the dealers are tied as to what GM allows or instructs them to do.
And in my searching, looking at Lincoln MKS's, I've won every bet because of GM's handling of an issue. It was discussed earlier in this forum and a few of you got the real fix. I did not. It seems GM decided it was costing them too much and they no longer replace those mounts on the rear shocks holding the protective boot in place.
If any of you doubt me or have questions concerning others comments about me, check this one item. Especially if you are shopping.
On every 2010 and newer Lacrosse, if it has as little as 600 miles in my experience, the protective boots on the rear shocks will have fallen down and they require new mounts. Rather small issue compared to the other problems I had but GM refusing to replace something that will effect the life of the rear shocks sums up GM's attitude toward every problem I had.

Torque converter is very unlikely. It and other parts inside the transmission all spin when in neutral, no clutches engaged. But there could be some issues associated from the transmission. Particularly at the output where the CV shaft plugs in, such as causing a wobble.
Struts should show other signs of issues, especially on different road surfaces. But I have heard claims of drivers bending the stabilizer bar. I can only imagine what sort of forces were applied.

Well it was only an example. It could be a bad motor or trans mount too. It could also be something like an exhaust component rubbing up against something. My point was that a vibration can come from many different areas and it seems as if the OP's dealer on investigated the likely source.

Madison and Chief. When we get the problem from hell, there sure are a lot of doubting Thomas'.
Can you say it is from front or rear? Isolating to one or the other eliminates or includes drive components.
They showing you another with the problem does not mean it is not a problem. Only that they are good at creating it.
Did the rebalancing, rotation, new tires, etc. make any difference?
Something that should have shown up with RFB would be warped rims/wheels. One thing I've learned over the years is that problems often come from the last work done. Your wheels have been off the vehicle so often, I'd certainly scrutinize them.
But without further guessing, can you relate more of the problem. Describe relative to speed, cold and warm tires or air temperature, the type of surface and condition, etc. Does it come and go at certain speeds or all speeds. Do you have touring package with full time electronic suspension?
GM should be volunteering to do almost unworldly things for you as a matter of customer satisfaction. I've heard from two former GM salesmen. One retired, suggested anything but GM truck. The other said he quit GM sales because he could no longer stomach looking customers in the eye. He now works at the same owners, one of their other brand lots.
And if the service calls it a lemon, yet you hang in there hoping for a good outcome, what would you call that? (It was not brand loyalty)
