Not only "could". According to the terms of the Consent Decree between the EPA and H-D which was signed into law in July/17 Harley MUST deny powertrain warranty claims if it can be determined that any '17-later motorcycle was tuned with a non-compliant tuner. And that means any tuner other than the Screamin' Eagle one. Below is an excerpt from the Consent Decree.
(Defendants in this case means the MOCO).

 

How about now Yukon42? Do you still believe your warranty is intact because someone at the dealer told you? They just tell you what you want to hear because they want your money so you wont install **** yourself that you could easily do over the weekend drinking beer but overpay at dealership. This is reality these days. Hope nothing go wrong on your ride anytime soon. Looks like 90 years old lady advice was sound - trust NO ONE ☝🏿

 

You may have been right a few years back. The EPA put a foot up HD's ***. They have no option but to comply.This is a EPA issue and the MF has nothing to say about it. The EPA is the first and final answer on it. It is not HD's doing.

 

To those who extol the virtues of Magnuson Moss: try reading it. It says that the manufacturer cannot deny warranty just because you used aftermarket parts or oils or filters or such, SO LONG AS those aftermarket parts meet the same standards as the manufacturer's own stuff.

What it does NOT say is "you can put any aftermarket parts on, and the bike manufacturer must always still warranty the bike."

Here is where it gets critical: if you are in California and you put on a part like, say, an aftermarket header that clearly says it is NOT legal for sale or use in California, then the bike manufacturer will in no way be expected by any court in the land to provide warranty coverage on a bike that is illegal to use on the roads! Harley's warranty states that explicitly.

That is how I also understand this. Makes perfect sense.

 

avalanche hd is full of incompetent service personnel ... I know ... I work there

 

Would your cool username be a clue as to what you do there?

 

You are both right. It comes down to dealer to dealer issue. and yes hd can be involved. My dealer sold me a tts tuner and tuned my bike. stand behind the warranty. But the new ownership may make that an issue. I believe that unless you have a lawyer with you they will *uck you. My local hd dealer just announced they now service metric cruisers.

 

if you used an aftermarket tuner then they will bend you and your lawyer over together and go in dry....even Perry Mason would come away sore as Hell
