Buick Lucerne Vibration Problems



  • 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...

    been in an accident???
  • not to our knowledge...carfax report does not show an accident...only show car was a rental return...
  • SO I had the vibration problem on a 2001 Lesabre Custom, balanced the tires 5 times and changed tires, no fix. So I found the brakes were dragging on one side of the rear as the brake cylinder was jamming crooked and not releasing properly

    Now I own a 2008 Lucerne, same vibration and changed pads and rotors and it was good for a couple days. The vibration is back. ( I expect using the parking brake has tightened up tolerances to the rotor) The common thing here is with both cars the vibration seemed much worse for the first 15 minutes of driving and then got slowly better. This to me indicates it is something temperature related. I changed the tires on the 2008 now and it still vibrates. Recently I used a dial indicator on the new brake rotors and found that one rear is not spinning true. This indicates the hub is likely bent as I also see the un-true condition when the dial indicator is run on the hub face. I will replace it but temporarily I spent the time to shim between the hub and rotor with strips of tin tape until the rotor ran through the brake pads with minimal wobble. It does feel better today but will have to run it for a couple of days to see if the vibration comes back. FYI I have already replaced 2 hubs on the other side of the car due to free-play. This car has only 80,000 kms on it (about 50,000 miles)
  • Update, new hub and this one runs straight but the intermittent vibration is still there. Taking it to the shop to see if they can find something??
