Well good luck actually getting it repaired any time soon if your area is anything like where I am in Texas.
I need to go in also for my second repair of this same issue. Our North Dallas dealers are so backlogged due to lack of engine techs and a backorder of the phasers themselves that they have a huge waiting lists of people trying to get in to get their phasers replaced. I brought my truck to 2 dealers and in both cases the wait, just to get the truck in the shop, is over a month AND once they have the truck they'll keep it 10-14 days file you sit around scratching your ***. ALSO, I paid very good money to purchase the ESP warranty from Ford so should be given a loaner while the repair is being performed however they have no cars and basically told me tough ****. Now, add to the fact my truck is getting close to 60K at which point the repair is under ESP and I'll be responsible for the deductible, even though it's Ford who's delaying the repair.
This is my 6th new Ford truck in a row and prior to all of this I'd have said I'll be moving on to my 7th. I've always been a Ford homer but it has me rethinking my next purchase. I'm shocked at the fact that they have millions of these 3.5 ecoboosts out there that are ticking time-bombs. Wait until all the warranties are out and they start to fail. It'll cost owners $$$$ to get them repaired.
