Got a new M3 in June, and have the Pillar blocked error (both, but R>L) every single day when I drive in the dark. This along with constant phantom braking (every day) caused me to finally bring into to service (car is there now, but ready for pickup). Provided many logged "bug reports" and specific times for both conditions. Was told everything is "operating as designed, no fix necessary". Tesla even charged me for the visit!! Tesla is totally unwilling to own up to issues with these cars. Not sure what else to do, other than consider filing complaints with NHTSA and BBB.
