Sometimes the electrics on my 2016.5 CX-5 die...Meaning I have to use the manual key to open the driver's door. The engine seems completely dead. But my daughter's friend told me to open the hood and touch the engine in a couple of places then try to start the engine again...It worked and didn't need a jump start. This is now happened once or twice a day. Any idea why? Btw, the battery looks like this at the moment.
