dealership cannot find problem. Had the car for several days. Convertible top will no retract, windows do not open, trunk will not open. Service manually forced the top to close. Gave me the car for the weekend need to bring it back. Computer tells them absolutely nothing. Service writer said they might have to dismantle all the lining inside the trunk area and do a diagnostic. Might be a harness. Really. Bells ring on dash for a short period. Windows have come down when I am nowhere near the car. A co-worker had to let me know that my car windows were open. There must be a ghost in the car. It has 26,000 miles.

I had the exact same situation and was only able to use OBD2 to close it manually and stop all codes to drive normally, currently not able to open or fix the issue fully though what did you do? Please help likewise
Having the same issue!! car won't stop dinging , I keep getting warning light that top is not secure to the point now it's running down my battery. It dinga when the car is off and while im driving.... trunk doesn't open either and automatic windows doesn't work anymore.
The problem is the roof latch sensor. It isn’t up front like you’d think tho. The sensor itself is in the convertible roof motor area driver side. Fix this and all your problems disappear. The sensor itself costs about $40 for a GM OEM part online. The man hours should take no more than 2. This isn’t a job that should cost more than a few hundred. Electrical problems affect different systems and that’s what’s happening here. I know because I have a ‘16 Cascada. A friend and I fixed it ourselves. I had exact same issues, warning light after car turned off and while on, trunk didn’t work, windows would go down on their own, etc. Did someone mess with your fuses by chance?
