My son and I replaced the pump and we still had a leak. Took it to the dealer, mistake, and they said it was the rack. Got it home and 2 days later had a huge puddle on the floor. Took it back and they said it was the high pressure hose.

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 !!!

The car makes a whining noise and dark fluid dripped under car. The dealer says the leak is coming from the steering pump and steering gear (rack & pinon) and both need to be replaced: steering pump & plastic reservoir ($576), steering pump only ($376), but reservoir often breaks during repair, steering gear with alignment ($924), plus $52 to diagnosis ($1550 total). price includes tax & mr goodwrench multi-point vehicle inspection.
The hi-pressure PS hose was replaced @ 87000 miles due to seepage- not really a leak. Two qts of PS fluid was added. About 600-700 highway miles later, while maneuvering into a parking area the PS completely failed. I checked fluid level-which was OK. Left it overnite and in the morn checked for leaks under the car and fluid level in the pump- all OK. Started car and drove off as tho nothing was wrong- PS was working fine and still is @ 6000 miles later. Have checked w/ 2 Buick dealers and several auto repair shops- all totally baffled. This is a real mystery.
