The reason I was concerned is because I also own a 2010 Edge Limited. 2 months into ownership, I noticed one of the rear window defroster wires / lines was not working. I took it into the dealer and received the "No problem found" response. Knowing the vehicle was under warranty, I waited until nother convenient time (year later) to bring it in. This time I took pictures of the failure with me. They put a patch on the line and it looked and felt awful. I complained about it and was told to "buzz off" by Ford. The dealer offered to pay half, which I accepted with great displeasure.
That experience left a terrible tast in my mouth and a major lack of confidence Ford Motor's warranty system.
You can't replace the individual button but the stack of buttons are replaceable. Make the dealer fix it for free.
Mine did the same but mine was installed afterwards so no warranty on it there it bothered me enough that I went and just bought the buttons and swapped it myself
$89 for the stack of cruise buttons
Yes. It actually is cake. I found pics here on the forums to remove the airbag. You have to stick a flathead screwdriver in 3 places from behind the steering wheel. Once the airbag is out, the buttons pop right out. However.... the steering wheel is crappy hard rubber. Mine busted right where the buttons inserted so I had to get creative with glue. Once back together of course you don't see my creativity
This problem is annoying. I fixed mine by peeling away chipped edges and sanding down edges smooth with nailfile emery board. Then I used auto pinstripe tape on the edges as it conforms to curves. Used to bother me constantly, now it actually looks like the tape was factory and no sharp edges.
