I have only recently purchased a 2017 venga 4 and has my 1st issue yesterday. It started ok when I went shopping but when I pushed the start button after shopping the power came on then went straight off but the engine didn’t start. When I pushed the start button without depressing t clutch again the power came on then went straight off. I rolled the car forward to push start noting happened and after just about giving up I tried 1 last time and it started. I’d this likely to happen again and what do I need to to to fix it?
