Brought a lawn mower with electric start from Amazon. The battery charged up the first time but since then refuses to charge. It said if there were problems to contact Genpower. It is still under warranty. Constant rubbish emails for weeks now and no offer to sort the problem out. I thought Hyundai were a good company - I had never heard of Genpower. Genpowers customer service has been rubbish and I now have a very heavy lawn mower without electric start. I am old and can not go on with the very hard to use pull start. My even older husband pulled muscles in his arm trying and 2 months on still can't drive. Mower not fit for the purpose it was brought and no help at all from Genpower. Will never buy Hyundai again while it means dealing with these idiots
