I have a 2007 g6. Bought it new, only 4200 miles on it.
I cannot get the trunk to open. I have an error that says the top is not secure. When I tried securing it by pushing the button to close the top, the windows come down and then nothing else happens. If I try to open it, it tells me to check the cargo top. I know the cargo top is not closed because I have luggage in there. Any clues on how to get the trunk to open?

Is the top up or in the trunk?
When you say you can't open the trunk, do you mean you can't unlock it? If so, are you trying to unlock it with the remote or with the button on the door? Have you tried both?
Or do you mean it does unlock but cannot be physically opened (lifted up) because of a physical obstruction of some kind?

The only way I have managed to fix the "top not secure" and "check cargo top" was to remove the rear seats so that I could get a broom handle or similar to pull the manual emergency release. It was a real pain but did work. I was somewhat fortunate that I already had the carpet like cover out and I had nothing in the trunk that would obstruct me. Similar it may be possible to fashion something that would allow you to hook the cargo cover switch.

A dealer or someone with a Tech II or similar high end diagnostic tool may be able to command the system to think the cargo cover is in place and complete the convertible top close cycle.

Hope you get it fixed.

Here ya go:

Car in Park; Engine OFF
Disconnect the battery terminals for a few minutes.

Reconnect battery. Do NOT start engine.

Your remote will now open the trunk.
Inspect for debris, etc, and ensure that cargo top ant its connectors are intact and flat, to prevent a recurrence of your problem.

Nice tip - thanks. I hope I never need it again but good to know. Much easier than removing the rear seats...

Take the negative battery post off for 60 seconds, put it back on and push trunk release. It should open ]

Yeah, I am wondering as well.
I had heard about it, and if I recall, the theory of this being that with disconnect, the top module goes blank, and you hit the trunk button before any top command and it works because it doesn't 'know' there is an issue.
At least that is theory.

another option

There is another option that I used when my vert ate the wire insulation by the hinges.
If you take the cover off of the electrical panel on the passenger side tunnel there is a relay in there that triggers the trunk lock. You can pull the relay and jump the connection to pop the trunk solenoid.
If you need this I'll look up which relay it is.

This works well.
How do we get the problem solved. It’s difficult to want to pop the trunk with hands loaded and first have to pull the neg. terminal off the battery.
I checked everything I know. The car has 212k miles and still runs great. Do GM dealers know how to fix this?

Getting the trunk open was one of the steps to be able to look into the issue more closely. Some have experienced frayed and broken wiring especially near the hinge locations where the wiring makes a sharp turn and has to flex. Sometimes it is a micro switch at fault. Someone with an advanced scan tool (dealer Tech II or something like a snap-on) will have the folding top diagnostics that should indicate where the problem is. If you cannot find the issue yourself it may be worth a diagnostic fee or seeing if someone will let you use theirs. From there is is a question of parts availability or if you can trace and fix the problem like the wiring. Hope you get it fixed.

since the top no longer works i would find the lockout switch and bypass it or run a new wire using the old switch or a under dash switch.you just need 12 volts to the trunk latch solenold or relay long enough to pop the lock.

for anyone interested, I too could not open the truck but found I did not need to remove the seats to access the manually release. Just remove the panel that has the logo on it, this will require you first removing the seat belt retainer, then lift upward for the center panel. once off pull the seatbelts up and place this piece on the package self out of the way. Then using a broom handle with a wire coat hanger taped to it for stability, form a secure loop on the end and go fishing. You will notice an opening between the seats that is large enough for a light, to see where you need to go, and the broom handle. this tactic took all of 20 minutes to complete.

My trunk will not open to begin receiving the top. It stopped working when dealer replaced hydraulics in trunk. When I wanted to open trunk normally, arms would not hold enough pressure to keep open. Now I can open normally, but no convertible. Any suggestions?

If I understand correctly, your trunk would not stay open due to the trunk's gas charged "lifts" being worn out, and replaced by the dealer (an easy fix). When you got the car back from the dealer, your previously functioning convertible top would no longer initiate top down cycle? If this is the problem, I'd take it back to the dealer and have them troubleshoot. Maybe the hydraulic rams are leaking, hydraulic lines were dislodged, sensor(s) or wires disconnected. Let the dealer figure it out...if they even know what they're looking at :rolleyes:.
