Any one had this problem? I was on holiday in Spain driving on the motorway doing 70-80 mph when vehicle lost all power. Luckily no one was injured I had 3 kids and partner in vehicle at time. Vehicle started again and drove for short distance and cut off again and displayed hybrid system fault. Had vehicle towed to Lexus dealers in Spain who diagnosed fault as hybrid converter and repair bill of 6000!! Absolutely gutted don't know what to do, would really appreciate help, advice,
