Ours was replaced by the dealer after about 1.5K miles. I had just come off the motorway, slowing for traffic lights at A road junction and at about 5mph the car cut out in drive, came to a dead halt, all displays dead, frantically turned ignition on and off and nothing, then after about a minute normal service and the engine started etc and away we went. Car went back to dealer where they went through the cars electrics remade all the earths following discussion with factory etc, following from that disgnostics showed an overseer fault code, so unit was replaced. Since then touch wood all ok.
