A couple of drops of a latte spilled on the dash a while ago. The buttons were a little sticky but ended up working perfectly after a few days with no stick. However, after a couple of weeks, they just do absolutely nothing now. Can’t turn off auto start/stop(which means always driving in sport cause I hate that feature so much), traction control, etc. The dealer quoted $2400 to replace it. Any other ideas before doing that?
