I think that depends on the installation. My gf had one for a year and there were very few issues with it. The most regular issue was nicotine spray setting it off. It had to be serviced once in a year and this service was included in the price. Personally I think a lifetime sentence is a bit harsh but I definitely agree that drunk drivers should have an ignition lock for a long time, perhaps 5-10 years.
