Fire in the engine wiring, fuse box, battery store parking lot parked engine off GMC took truck said it wasn't a factory issue no information was given to me said it was confidentual had truck 6 weeks
Truck enters padlock mode have to wait the 10 minutes then try again, a few times it did it again- now 20 minutes gone. Lately this is happening once a day. This happens when parked.
After about 2 years after we had the truck serviced for valve system issue which we were notified about via mail. We began having these starting issues that many of you are also describing. We took it back to dealer as it was still under warranty. We were told they needed to do a complete diagnostic on it which we could not afford. We purchased the truck in 2007 with 25000 miles and full warrantee. But diagnostics isn't part of that. So we have only recently began investigating tis issue more in depth, as we were told it was probably an intake issue or and exhaust issue. Only now are we seeing that it may be due to this passlock security issue that many of you are also mentioning. Over the years we also have experienced the same identical symptoms with cranking yet no actual start. Wait approximately ten minutes and she fires. It happened randomly at first. Then became more frequent. After fueling up etc. But not immediately after fueling. Now it has become almost a weekly occurrence. And the duration for wait time is lengthening to 20min-1/2 hr. All this time I allowed myself to believe it was something with the fuel system.... if this is a common problem....others need to be made aware as well. Is this a defect that was overlooked or blatantly ignored and not shared with the consumers? it does pose to be very unsafe in multiple circumstances. If this is an known issue, then why are we having to learn about it from one owner to another. Because no mechanics (dealership or other wise) has ever mentioned this as a potential issue.... always the same story. Must be a different issue... etc. But to realize it is a security feature gone whacky..... I don't know how any of you feel.... that doesn't make me feel safe. Thank you all for all your help and information.... thank you ever so much.
