Pure B.S. Dealers have been singing that tune for years. Magnuson-Moss Warranty Act of 1975 prevents them from voiding a warranty unless they can prove the modification caused a failure.
danoday - that is true. But by saying it voids all warranties they are saying if you install aftermarket slip ons and your radio fails then too bad. That is BS. It has to be proven to be a related part and a contributing factor to the failure to void the warranty.
MisterB - Harley cannot sell bikes that violate the EPA standards, and that is what they were busted for. They installed parts and tuners that took the bikes out of compliance and then they sold them. If you come in with your V&H slip ons and new A/C and have them remap it, as long as that map complies with EPA standards they have no legal reason not to. And since they push their own SE parts and a remap, they can use that same remap on yours.
The Magnuson-Moss Warranty Act is about doing scheduled maintenance and repairs. Once you modify a vehicle with off road or race only parts ( Not CARB Approved ) it is no longer the street legal vehicle you purchased with a warranty for it's intended use.
Harley still has the SE street tuner thats CARB approved , the race tuner is discontinued ( SERT Tuner) my dealer never recommended the street tuner because of it's limitations , now thats all there allowed to sell / use. Knowingly Selling, installing, and warranting the SERT tuner for street use is what got the MoCo in trouble and probably some butt hurt VW owners crying to the EPA.
My dealer who use to mod with HD or aftermarket parts and still warranty them told me no more , 2017 is post EPA sanctions and the MoCo will no longer cover warranty for mods that aren't CARB approved. Can't blame them either , there not allowed sell or install the stuff anymore why would you warranty it.
Fuel Moto also told me you can mod the 2017s as long as you don't care about the warranty.
No joke as I was signing the finance papers for my 16 the parts manager came in to tell me I had bought the last SE super tuner at that dealership, and that they were pulling the remaining 5 they had and could no longer be sold.Man oh man. What a shame. So glad I got a 2016
