So my 2016 Cforce 500 HO's EFI light was flashing on the dash. There was also a constant humming sound which sounded like a fan running while the unit was on as well. So I took it to the dealer and after two weeks and me constantly calling them they said my throttle body assembly needs to be replaced. Even though the unit is less than a year old and only has 83 miles on I am told it's not covered under the warranty...only 90 days. My first question is the throttle seemed fine on it so is it really the throttle body assembly? Secondly is there anyway this would be covered under warranty since the machine only has 83 miles on it? Has anyone else had this problem? The dealer wants over $400 for the part plus labor for the install....I hate putting that kind of money out for a machine that was hardly used. Any input would be greatly appreciated. Thank you!
