NHTSA Complaint #11489431 — 2002 CHEVROLET IMPALA

I was driving along when out of no where my trunk opened. I got off the highway and closed it. At that time I was puzzled wondering who had been in my truck to have not closed it correctly. I knew I hadn't been in it in awhile. It wasn't until a few weeks later when the "Service Vehicle Soon" light on my dash came on. I went and had my vehicle scanned and was told about the TrapAlert system in the trunk and that is why my trunk popped open. I realize there was a post about this like a decade ago. But this is happening to me now and I can't find help for this issue anywhere. I've contacted both Chevrolet and GM support online as well as repair shops and no one seems to know what I'm talking about. GM told me they don't keep info on Vehicles older than 10 years. All the information online would suggest there is an actual sensor somewhere in the trunk although extremely vague on where it actually is and that it has a disable switch. Well, we've tore this thing apart only to find out it's some looped wiring that goes into the stereo amp in the trunk. I've yet to see a sensor yet for some reason my vehicle is still giving a single that someone is trapped in the trunk thus, popping the trunk whenever it wants. I've been searching high and low for information and already spent $1100 to repair issues to clear the dash light and nothing seems to work. Just a waste of time and money and considering this happened while I was driving 55mph I would think it obvious that its dangerous. Could we at least get some actual information without having to spend more than the Vehicle is worth. Smh
