i have found a leak on a line that it is running up behind the passinger side of the motor . there are 2 lines and they are wraped in a protective sheating. they appear to run to the power stearring resavor. is this what im looking at? and whats the best way to replace them ? Or are the lines going to something different.

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 !!!

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!!!!!!!!!!!!
