AROUND 3 YEARS AGO. 3 PARTS THE LANE DEPARTURE MODULES CONTROL ARE THE BLIND SPOT SENSORS, REAR BACKUP SENSORS AND A FRONT CAMERA. MY LANE DEPARTURE MODULES GOT WET AND MESSED UP MY CAR WHERE THERE WERE MANY THINGS GOING WRONG. WHILE I WAS DRIVING MY CAR SAID THE AIR BAG WENT OFF, THEFT WAS DETECTED, BLOWER FAN & TEMP CONTROLS WHERE GOING ON AND OFF WHILE I WAS DRIVING. 2 YEARS AGO GM AGREED TO REPLACE THE MODULES. THE DEALERSHIP SAID THEY WERE HAVING PROBLEMS WITH THE PROGRAMMING OF THE MODULES. THEY FINALLY GOT THEM TO PROGRAM. THE DAY I PICKED UP MY CAR I NOTICED ISSUES WITH THE SENSOR SYSTEM. THEY SAID TO DRIVE IT. I TOOK IT AND THE PROBLEM GOT WORSE. WITH THE BLIND SPOT SENSOR, ON THE PASSENGER SIDE GOES ON AND OFF ALL THE TIME, I HAVE PICTURES AND VIDEOS SHOWING WHERE I AM DRIVING WITH NO VEHICLE NEXT TO ME AT ALL WITH THE LIGHT FOR THE SENSOR SHINING BRIGHT. THE REAR BACKUP SENSOR DOES NOT WARM ME, LAST WEEK I DID NOT SEE A GARBAGE CAN BEHIND ME BECAUSE IT WAS LOWER THAN MY TRUNK AND I HIT THE CAN AND BROKE MY TAIL LIGHT. THE FRONT SENSOR THAT TELLS ME I AM GOING TO FAST FOR THE CAR IN FRONT OF ME GOES ON RANDOMLY WHEN THE CAR IN FRONT OF ME IS MORE THAN 100 FEET OR NO CAR AT ALL. I HAVE TAKING MY CAR TO 3 DEALERSHIPS 4 TIMES. ALL THE DEANSHIP'S SAY THEY CAN'T FIX IT BECAUSE THEY DON'T GET A CODE. THERE IS NO CODE FOR THIS, NOT TO MENTION WHEN MY LANE DEPARTURE MODULES FAILED THERE WAS NO CODE FOR IT, THEY JUST STOPPED WORKING. THEY SAY IT IS UNDIAGNOSEABLE. GM SAW
