In owners' own words
I was cut off by another driver in rush hour traffic and the horn failed to operate when pressed. After this incident, I discovered that the horn does not work after the vehicle is driven every few miles! The vehicle was in the shop for hours of diagnosis, and finally it was discovered by the technician that the vehicle has a bad "sir coil". The "sir coil" is on special order.

Intermittently the vehicles passlock security system disables the starter leaving the driver and passengers stranded for 10 minutes while the system resets itself and reengages the starter. This issues seems to occur at random, I have not been able to duplicate the problem at will. An internet search on the passlock security issues proves that this is a common problem with the H3.
