I was in for one of my free oil changes, was told about three active recalls on my 18. Block heater, something to do with the rear defrost and a supplement for the owners manual. There was also the injector calibration update that they were going to do.
I asked them nicely not to do the injector calibration and NOT to cut my block heater cord, they complied with my wishes. I used the block heater all winter last year without any problems, I've inspected the cord and the element and can't see any problems so I will continue to use it until the parts are available for the fix.
