i have a 2011 Corvette convertible , manual transmission. once in a great while i will push the button to start it and all the guages bury to right then go back and nothing happens. when it happens it is usually only 1x then it starts.
last week same scenario…EXCEPT IT WENT DOA. everything went dark for 30seconds and came back only thing that stayed on while it was DOA was some dash lights and idiot light for brakes was also on so i knew battery was not dead.
this went on for 1/2 hr, luckily i was home so i got my jumper box, checked battery terminals, spotless and soild. tried jumping car but nothing.
after doing online research i stuck fob in slot and Voila it started.
since then not a problem at all but fob in slot 1x does not mean issue fixed. dealer baffled, not spending couple hundred dollars for them to guess.
