Hello, I just bought a brand new Fusion Energi less than 2 months ago and I do a lot of driving and have 10,600 miles on it already. My check engine light came on a week ago while in Tucson and dealers are not open on Sundays so I had to drive it home to California. The car runs totally fine except now I cannot pre-warm the car in the mornings with the remote start. One dealer said it's because of the engine light being on and a different dealer said it should still work. Anyways, seems Ford service is very busy and the three dealers by me said if I bring it in, it might sit for up to few days until they can look at it. I don't want to pay for a rental car for 2 days before the car even gets looked at. I went to the dealer this evening and at least they got the code which is P04EF which in other threads I've researched means small leak detected and some said it was a canister purge valve. The description for the code that Ford ran says ISO/SAE RESERVED and the service department didn't know what that means and it needs to come in for full service to the techs can do a full diagnosis. I have an appointment for Wed but again, they say they will try to have my car looked at but it could be a day or two until it gets looked at. I'm just seeing if anyone out there has experience with this and to know possibly what it is. I'd hate to have my car there for two days and then looked at and then find out a parts needs to be ordered and that will be another few days. Sorry for the long post. Thanks
