THIS SHOULD BE A STICKY

Get the most out of your investment - The manufacturer’s warranty and any rebates offered by Pioneer are not valid when you purchase from an unauthorized dealer.

I learned this the hard way with my Z150BH, so with my NEX8000 I purchased a warranty from Squaretrade which still saved me $300 over retail cost and provides coverage for 4 years rather than 1.

Great point think I'm going to take my chances with the 4000

I think if we're going to advocate for something it should be for Sherman Act indictments aimed at Pioneer.

Price fixing is broadly illegal in the United States, you see.....

Hmm, that sucks... I got mine from a local dealer and didn't even think about this. No one else had them and I didn't want to do the install myself... Sure hope that doesn't blow up in my face...

Doubt it if you're aggressive.

The implied warranty of merchantability and fitness for purpose cannot be disclaimed or evaded.  It attaches to anything sold at retail, by anyone.  Period.

A defective unit fails this test.

Now if it doesn't last as long as one would expect, where a normal warranty would be the remedy, you might lose.  But a unit that fails a week into ownership or something similar is a different matter.  Nobody could defend said unit being fit for the purpose sold, and that's a warranty they can't dodge.

You might end up having to sue them in small claims, but I bet not.  You will have to be aggressive however.
