I took mine in on Monday around 1:00pm to have the recall done. After they looked it over they said that they had to do all four nuts but it would take about four hours. So they gave me a Deville to drive. They call me on Tue. at 7:30am saying it was done. They did a nice job of cleaning the car before I picked it up. Seeing as they have to do all four corners it will take about four hours if they only have to do the NUTS.
