How does a seat "QUIT"? Please be specific. A seat does not quit, it may be forgetful which is common in almost all electric/memory car seats, especially German and English cars. If that is what you mean, then my driver seat does that every 3-4 months. No big deal. PARK. At DIC, push the top button on lower right steering wheel column. DIC says DRIVER 1, then SEAT MEMORY. Set your driver seat position, push button 1 for few seconds until it beeps. Do the same thing a few months later.
If it just went DEAD, then a simple fuse or connector problem could be it.
Of course, you can get really angry about this, jump up and down and demand an apology, instant repair or replacement of seat, but that wouldn't help much.
