My car leaks power steering fluid. I get a few drops every day, and must add fluid about once every 4 weeks. It's messing up my garage floor. Is this a common problem and is there a common fix? Before I take the car in for service, I was wondering if many have experienced this problem??

BTW - I have a 05 STS-V8 RWD with 35K miles and no warranty.

Regards...

This happened to my STS-V at about 10K miles. If I recall correctly, there were some plastic fittings that had become brittle and cracked where the fluid lines go into the power steering pump. Mine was fixed under warranty, but I can't imagine that it would cost much to fix yours. If it's the same thing, I think it is a simple fix with cheap parts.

Ya gotta fix it. My old Triumph is allowed to leave a trail, but not a Cadillac. I'd bet there's a hungry dealer or tech who could take care of it. Maybe ghemrick's right and it's not as bad as you think.

I too had a leak and it turned out to be a hose that went to the power steering cooler, not all STSs have this, I think. I have the ZF option. I replaced the hose and put on a couple of gear clamps instead of the spring type. Worked for me.
