I would like to make people aware of a serious fault in smart4two front coil springs. We have had both fail. The first after 26,000 miles and the second within 10,000 later. We were lucky in that it did not cause any other serious damage but I have read that others have had shredded tyres and worse! To top it all, the manufacturer and our dealer Mercedes-Bristol have refused to pay to put it right. I think this is a serious safety issue. It appears that they going to wait until someone is killed before they recall this.
