Chevrolet Volt won't start despite charging all night and full tank, no propulsion issue on Chevrolet Volt

Some Chevrolet Volt owners report experiencing issues with their vehicle not starting despite having a fully charged battery and a full tank of gas. These problems can often be attributed to battery or alternator failures, which may prevent the internal combustion engine from starting if the high voltage battery has failed. Additionally, some owners have noted that a "service charging system" message prior to the vehicle shutting down could indicate a faulty generator that fails to charge the battery effectively. Furthermore, issues with the 12V battery have also been reported, where jumping the battery may help when the car is unresponsive. It is advisable for owners facing these issues to seek assistance from a professional mechanic for proper diagnosis and resolution.
