I had a water pump replaced December 12th by a shop with a pretty good reputation. Last night I noticed it's leaking everywhere and the car won't hold the coolant. My father thinks they'll replace the part for free since Toyota has a 1 year warranty, but that I'll be on the hook for the $500 in labor they originally charged. I had the extended warranty at the time so I only paid $100 of that plus tax. I can't afford a $500 labor charge right now, would a shop really do that, put in a faulty part then only cover putting in another?
