I had a problem with my pathy not starting, replaced 3 burned out starters in 6 months!!! finally the only people who figured it out was Nissan, the alarm was drawing too many amps "somehow from the starter?" and so I told Nissan to just disconnect it. They did, and I haven't had 1 problem since. (when i would turn the key, it wouldnt do anything....sometimes took 15-20 tries at starting it, then would just go out)
The alarm is still there, just disconnected. Hope this helps. Actually didnt cost too much either, just a small labor charge.
