Suspect the 48v battery doesn’t work. Had car from new and ISG worked about 50% of the time initially but after 160 miles it has stopped working even after a 30 mile run. The claimed Cruising Stop Go feature has never worked.
Either battery or charging mechanics are not working. Been waiting four days for garage to contact me.
