The ignition switch shorted, a fuse shorted and these symptoms revealed a bigger problem. The holding area for the tire in the rear (does not hold a tire because of space issue) was repurposed by the manufacturer to mount the rear fuse box and amp. When the sunroof overflows or gasket allows moisture to build this area holds water. Unknown water source at this time but there is no drain for the water directed here to go out. Subsequently the electrical is exposed to water causing a fire hazard while driving or running. In my case it melted various relays and wiring harnesses but I was able to find before the fire started. This is also in the vicinity of the fuel tank causing an extreme hazard. When researching I found this model car there were many that had reported it. This could have been extremely dangerous fire while operating and is completely preventable with small alteration. Water should not be directed to this area if it will not have a way to vacate and they have repurposed the area in this way.

Convertible top rear window delaminates due to faulty design and/or insufficient bonding of glass to fabric material of top. This has happened to my car twice within less than a year. Top was replaced once and now I need it replaced again. Glass could potentially fall inward to injure a passenger or fall out onto the roadway or into a following vehicle. So far GM's solution has been to replace the convertible top with another defective top.

I was driving on the interstate, about 65 mph, and the phone charger caught fire and exploded. I stopped the car on the interstate to extinguish the fire on my person. The charger fell under the passenger seat, and caught the seat on fire. The whole car was consumed by the time the fire department responded to the scene.
