Well, at 42723 miles, my water pump sprung a leak, all over the floor of my garage. I am not sure how you can call that anything but a failure. The check fluid level light came on my commute home. It started flashing, but the temp gage stayed at 190 so I drove it home. I let it cool down and then went to see what I could see. A puddle growing around my left front tire told me that it was going to the dealer. I had AAA tow it to the dealer where the offending pump was replaced under warranty. On the up side I had a nice Passat Service Loaner until I got my GTI back.
