The H2 has now sat at the dealer all week and they dont have a clue. I am asking for a new ignition switch with fingers crossed. Let let you know how I make out. Will pull the onstar fuse when it gets home.

Thanks for the replies!

Great info Humtech!!!! Subscribed for the dreaded future.

OP- Is your battery going dead? Or other issues?


If bat going dead install the priority start module, problem band aided well!

No battery issues. I'm now leaning toward anti theft issue. If I cycle the lock and unlock on the key fob 10-15 times it starts at ramdom. The problem also seems to occur more often when the temp drops below freezing. Really wierd. A friend suggested having a remote start installed and bypass the system. Does anyone know if there is a seperate anti theft module or if it is built into the main computer?
