Mine started squeaking after one month from driving from the dealership, annoying to a point that I wanted to return the car and get my money back if I could. So they replace the entire seat base. Worked for about 6 months, then started squeaking again. Took it back and they replace the seat base once again and according to them to a new "upgraded" part that "seems" to have solved the issue... (#not) 10 months later squeak is back again... took it back to the dealership for its 2nd service (2yr), showed them the seat again, and after the service, they say, oh... just raise the seat about this much and the noise stops (which for me that's not a fix, as the seat is designed to go up and down as much as you want, our guys tested. Drove out of the dealership on the first corner squeak again... turn around straight back, now they want my car for 1 week to see what needs to be done...
