Buick Lacrosse owners have reported 1 problem related to vehicle shudder (under the power train category). The most recently reported issues are listed below. Also please check out the statistics and reliability analysis of Buick Lacrosse based on all problems reported for the Lacrosse.
At 25 - 30 mph and at 45 - 50 mph the car shakes violently. I took it to the dealership for a diagnostic. They said they knew exactly what it was. I need a new lower and upper transmission. That is the recommended fix. That is something that happens to chevy transmissions and the cost is $5400. It seems to me that if this is something that goes wrong all the time, that's a problem that I did not create. My vehicle is worth less than the cost of the fix and I still owe more than twice the cost of the fix.
