Wesley Sherwood in Ford Communications confirmed in an email that Ford will offer an 8 year/100,000 mile warranty on the battery of the Focus Electric.
I asked Wes if he could comment on what specifically Ford would guarantee with that warranty. Will post a response if I get one.
A prospective buyer had noticed that his Monroney Sticker for the Focus Electric he had ordered was listing the "powertrain" warranty at 5 year/60k miles, and cars.com was showing the same info.
Here is the text of the email:
I can help with your question. We will offer an eight-year, 100,000-mile warranty for the Focus Electric battery and EV-specific components such as the motor. I hope that helps, and please let me know if you have other questions. Thank you.
