TODAY I WAS DRIVING MY 2012 BUICK VERANO AND WITHOUT ANY ADVANCED NOTICE (IE.. LIGHTS ILLUMINATED ON DASHBOARD) MY VEHICLE LOST POWER AND JUST STARTED TO CREEP TO A FULL STOP. THE DASHBOARD WAS BLACK NOTHING TO TELL ME WHAT THE PROBLEM WAS. THANK GOD THEY HAVE CREATED A LARGE PULL OFF ON THE HIGHWAY OR I WOULD HAVE BEEN REALLY HURT. I TRIED SEVERAL TIME TO RESTART MY VEHICLE THE RESTARTING PROCESS WAS NOT THE PROBLEM IT WAS PUTTING THE CAR IN GEAR EVERY TIME I TRIED TO PUT THE VEHICLE IN GEAR IT WOULD SHUT OFF AND THE ENGINE LIGHT IS NOW ON.
IT HAS ALWAYS DOWN SHIFTED HARD AT ABOUT 28 TO 30 MPH, WE ASKED THE DEALER AND HE SAID IT WAS NORMAL, I HAVE NEVER HAD A CAR DO THIS, AND WHAT I AM AFRAID OF, IS IT WILL GO BAD AFTER THE WARRANTY GOES OUT AND I AM STUCK, I HAVE READ OTHER REVIEWS ON THIS AND OTHER PEOPLE HAVE HAD THE SAME PROBLEM?? PLEASE HELP ME FIND OUT ABOUT THIS, IT ONLY HAS ABOUT 6500 MILES ON IT NOW, AND WE BOUGHT IT DEC 28 2012, IT WAS DRIVEN BY THE FINANCE MANAGER AT FUSON BUICK IN TERRE HAUTE INDIANA,AND THEY SOLD IT TO US AS A NEW CAR WITH 4 YEARS WARRANTY, THANKS AND HOPE THAT YOU CAN HELP US.
