2001 HD Security light

My truck's security light comes on while driving down the road. If I get out while truck is running and get back in security light is on. When I start the truck it will come on right of way. All of these scenario's happen at different times and not all the time My dealer has been no help what's so ever. Also sometimes truck won't start and the security light will flash 5 times go to battery light then flash 5 times again and again till it eventually starts turning key on and off for about 15 minutes. I know there is another dealer I'll never again buy a vehicle from again.

Welcome to the forums I hope you can be patient in getting your answer here. People are usually quick to help out, but being the holidays I guess were all busy. There are some very good GM efficionados here (GM gurus) and I am sure one will chime in soon. I am a new GM owner, so I am afraid I cannot be of any help, but hold tight and the regulars will be here to help you!!

Good Luck!!
