Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This bulletin provides a procedure on how to check for a battery drain utilizing the Picoscope and how to measure the load on the system that may be causing a drain.

At random times the car will get the check engine light (Code P2138 when scanned) & show a message on the dash saying “engine power reduced”.

The "Safety Restraint system" service warning kept coming on the dash. The chevrolet place said they would have to change the "connectors" on the sensor under the passenger seat. So I had to pay them $100 to fix this. My passenger could have been in danger of NOT having an airbag deploy if needed if I was to get in a wreck! Yes the problem was confirmed by Westgate chevrolet in Burgaw, NC.
UNKNOWN issue but when gas peddle is pushed and speed is above 65MPH the vehicles dashboard lights go out and the car starts to sound as if it is going to shut down and power to the vehicle is declined dramatically.
The trunk will not open. It will not open even using the keyfob, using the actual key, nor pressing the button on the driver side door. There is a constant message saying that the trunk is not secured and the car is constantly alarming because of the trunk. Unable to open the convertible top. Message says to open top manually. There is no way to manually open the top
