when does Ford powertrain warranty starts ?

I have a Ford E-450 RV and my warranty started the day I bought it. Fortunately I haven't had any trouble except a fuel pump failing after 8 yrs. My local Ford dealership absolutely refuses to work on my RV with the reason it won't fit inside their garage bay doors so I found a service center that works on large trucks and motorhomes as well so I got lucky. Good luck.

It should start start from the days your bought it from the the Ford Qualified Vehicle Modifier (i.e. MH manufacturer).
Ours was a year old but never sold/put into service until we purchased it from the MH dealer. It needed new wiper blades when were we driving home, the Ford dealer did not have any record of the vehicle in their computer at the time. It took about a week for the MH dealer to get the 'paper' work to Winnebago, then Winnebago to Ford(US0 and then have it forwarded to Ford(Canada). The Ford dealer did honor the warranty and said that they would deal with it after.

You would have to check with your MH and/or Forrester to see when the MH was original put into service, possibly as a demo.

Can't say on RV's, but my 2010 Expedition warranty is 3 years bumper to bumper, which would include check engine light. It is MUCH longer for the powertrain, which does NOT include check engine light. Perhaps that is the confusion?
