I have selected "me too" to 3 other common problems with the Lacrosse. I contacted buick for assistance on repairs and they said Garber Buick in Saginaw Michigan would only agree to $50 assistance on a $443 repair bill. How sad! But they had no problem taking bail out assistance from my tax paying money!!!!!!!!!!!!

Had fluid leak took it to my mechanic said it was power steering lines then called Buick took to them and for 50 dollars replaced lines. Then just over a year later did it again but no help from Buick. Took back to my mechanic and he spliced it so far so good. Re-call not likely. no more Buick's !!!
