When they said it would take 3 weeks, I doubt if they meant the work itself will take that long, right? See if you can get them to receive the new parts in advance so you can just give up your car for one day for completion. I'm about to check back in to my Ford dealer to figure out why they can't seem to get the part after over a month. Hoping for a modem too.
Unless you want a loaner because the Focus is no longer safe to drive. I'm still driving mine, hoping the differential spider gear shaft pinion doesn't break.
Anybody actually heard of a failure? Likely small percentage.
Got the car back last evening. What I was told by the Service Advisor was that on the day that I dropped it off, they tried to do the update (whatever that means) and that didn't work. They had to order a number of parts (mentioned 12 parts) that had to be replaced. They were able to get the parts pretty quickly, but their transmission shop was backed up about 2 weeks. I think that they did finish the car about a week after they got the parts, and I was without the FFE for about 11 days. They said that if I take the car out after the initial update, that I will have to get back in line for the transmission shop.
With regards to the loaner, the dealer said that it was a recall and they cannot get me a loaner. If I had the extended warranty, then they would have got me a loaner. Ford said that they could get the parts out next day, and the delay is with the dealers transmission shop. So, that was not resolved. Anyway, the lady at the dealer who was trying to get this resolved made an extra call, and got Ford to agree to reimburse me if I pay for the loaner. I was "car-sitting" for a friend, and needed the loaner only this Mon, and returned it yesterday. So, paid for 3+ days, and should get the $115 back within a week.
