I'll update this thread as I learn more from the dealer.
My wife's car, a '14 FFH Titanium with 14k miles, started making an almost imperceptible noise from the front end last week. She had me drive with her and I honestly couldn't hear anything other than what I thought was typical road noise. Fast forward a few days and we went for a ride again. This time however, I could also hear a very slight cyclical grinding noise. It sounded like a break pad/rotor was grinding ever so slightly. It was easier to hear when in EV mode, but also seemed to occur when the gas engine was running. It happened consistently when accelerating, but I think I heard it occasionally when the car was coasting and breaking. It was definitely coming from the front/center of the car. No error codes or warnings on the dash and we did a vehicle health report which came back with green check marks for all items other than the recall section (sync warranty extension).
Since we had purchased the ESP with both first day and enhanced rental, I decided to take it by the dealership the next day. Called them up and they said they'd take a look. Dropped it off and they sent me off to the rental car company (without giving me the enhanced rental rate...)
Got a call from the dealership later in the afternoon and the service rep said that it was a problem with the transmission. They had hooked it up to the computer, went through the troubleshooting steps and then the computer told them to stop what they were doing. It said they needed to order a new transmission from Detroit and have the existing transmission sent back to the factory for inspection. Not what I wanted to hear for a car that's only 6 months old. But at least they are still making new transmissions and I wasn't getting a rebuilt one (or so I'm told.)
I'm curious, I've read the threads about leakage, but have others had to do a full replacement? How many miles?
I don't know the gritty details yet, but I'm hoping they'll share them with me and I'll make sure to post back.
PS. I did get the rental situation worked out. They claimed they didn't see enhanced rentals very often so they just gave me the $30 a day default allowance instead of the $75 that I paid for. Funny, since I mentioned both first day and enhanced two different times to the rep and he would only repeat back the "first day" option. I didn't notice they did the $30 allowance until the rental company was walking me out to the car. Once they told me about the transmission replacement they were quick to agree I should have the rental car upgraded asap
