2010 RAM 1500 — BACK OVER PREVENTION:WARNINGS:EXTERNAL/PEDESTRIAN ALERT

THE REAR BACK UP SENSORS STARTS TO WORK VERY LATE. WHEN I PUT MY TRUCK IN REVERSE (LEAVING MY CHILD AT SCHOOL) I WENT ABOUT 10FT WHEN I HIT A LIGHTNING POLE IT START TO WORK WHEN THE POLE WAS ABOUT 1 FT AND I CANT BRAKE. THANK GOD THE RESULT MY CHROME BUMPER WAS DAMAGED I THOUGHT IT WAS A CHILD. RECENTLY I PUT THE TRUCK ENTERING IN REVERSE TO MY GARAGE AND THE WALL WAS ABOUT 1 FT AND THE SENSOR INDICATES 3 FT. (3 LINES) IN THE DASH MONITOR. THANKS. OTHER THAN SINCE NEW THE TRUCK WORKS PERFECT! BUT I THINK ITS A VERY IMPORTANT ISSUE. THANKS AGAIN. *TR
