My 2006 MCS has been fairly reliable. Just hit 113,000 miles and replaced the lower control arm bushings last month. Onlt $200 in parts and 4 1/2 hours of my time. Huge difference on on improving the handling and getting rid of the front end clunks.
Airbag light is on due to the passenger seat sensor needing replacement. I plan on using the plug in airbag emulator to extinguish the light and has the PS airbag deploy when needed before sensors were required in the seat pad.
