Firstly the passlock system is a huge issue, if the parts in the system ignition system break down or trip you can be stuck high and dry on a whim. Passlock system is prime reason for my worries when driving my truck will cut fuel out and shut down and stall when I'm driving or need to start up my truck again also the blower resistor and cable are faulty as are other electrical systems but the blower motor resistor is outright a fire hazard that can melt or burn out. Gm needs to stop fucking around with passlock system and other issues I will not be driving or owning another gm in my lifetime after my troubles with this passlock system nobody should be having to deal with this problem 3rd party or have repeated service or parts installed to silence this issue for a time. Just think of having been stuck high and dry threw not fault of your own outside the passlock system there are quite a few very very negative problems many have had with these 2 systems above I would love gm to pay me for missed work days and personal expenses for having had to fix mend and make this system work as I stright up bought a new ecm/pcm tuned it removed passlock because the risk and issues were to great nobody needs this problem hanging over their heads this issue pisses me off as I'd spent days doing relearn procedures 40 min per procedure several times until one stuck as per instructions gm wont even respond or not fuck this up if you need service too I will not be owning any more gm or chevy again. If you need to fix this system just remove it. So sad dealers are greedy and gm is too rather then make things right with long standing issues and complaints passlock system and blower motor and a few other things need recalls no ifs ands or butts this is exactly how you will go bankrupt again fucking customers who paid for your broken sales pitch to buy your snake oil.
