2013 Volvo V40

HELLO . I APPOLOGIZE FROM MY BROKEN ENGLISH. THERE IS URGENT AND IMPORTANT SAFETY ISSUE ABOUT VOLVO 2014 V40 AND PROPABLY SIMILAR VOLVO 2014 MODELS . ALL V40 S , IN NIGHT LIGHT , NIGHT TIME DARKNESS, LOOSE THEIR COLLISION WARNING SYSTEM EVERY EXACTLY 18 MINUTES OF ENGINE RUNING TIME . YOU MUST STOP ENGINE , SWITCH OFF ENGINE AND START AGAIN TO SOLVE THE PROBLEM TO ANOTHER 18 MINUTES TIME . IT IS OBVIOUSLY SOFTWARE MALFUNCTION . WE HAVE 3 VOLVO V40 S IN OUR FAMILY , 2 IS MINE. EVERY 3 V40 S HAVE SAME PROBLEM. IN DAY LIGHT WORKS VERY GOOD . IN NIGHT WORKS GOOD TOO FOR JUST 18 MINUTES FROM START ENGINE .IN THIS CASE ALL OF CONNECTED PREVENTIONAL SYSTEMS LIKE LANE KEEPING AID AND PEDESTRIAN DETECTION AND COLLISION WARNING AND AUTOBRAKE SWITCHES OFF PERMANENTLY WITHOUT ALLERT OR NOTIFICATION TO DRIVER . IT IS FATAL PROBLEM . PLEASE PLEASE SUE VOLVO FOR THIS PROBLEM . BECAUSE THEY KNOW VERY WELL ABOUT THIS MALFUNCTION AND DO NOTHING FOR IT . I TOLD THEM AND THEY SAID YOU CAN NOT SUE US FROM TEHRAN. AND WE WE DO NOT LET THIS PROBLEM PUBLICATE TO PEOPLE ! IT IS NOT ABOUT COUNTRY OR REGION , EVERYONE CAN BE KILLED IN SUCH CRASH ANYWHERE OF THE WORLD . IF YOU WANT DEEDS OR PHOTOS OR TESTS I CAN HELP YOU . THANK YOU .
