First registration 30.9.2009 my just 3 years old I20 lets me down about 1x per month and doesn’t start. I had it read out, no error message. The dealer recommended that I close it, open it after a 1-minute break with the second key and then try again, usually it works that way. But last week everything didn’t help. He didn’t jump on. I left him standing, it was in the evening, went to pick him up the next noon, he jumped perfectly. But I can mic h no longer rely on it anymore. Especially when I get the mobility service, it can be that it starts again without any problems. I’m completely perplexed, how should I proceed now? Who has a tip for me????
