Just took my 2010 V6 Limited in to check out a sort of wooo cabin noise. Can't tell if from engine or rear, but car has a history of trans noise (had trans replaced under warranty right after purchasing about 3 year ago). Toyota now says the noise is because water pump is leaking (very slowly they say) onto belts in engine. Here's the kicker: I thought the CPO warranty was the extended warranty for 7 years/100k miles. Haven't hit 100k miles yet, but they say the warranty ran out in June, which would make it 3 years. Can't find any warranty like this on Toyota's site, nor can I find my warranty papers (yet). Any thoughts? I'd like to write to Toyota to get a straight answer, but don't know where to go. Thanks.
