    Does anyone have a problem with the collision light comming and staying on for a while? Mine will come on and let me now the system is off. It will stay on 15 mins to over a hour. Dealer saus no faults show. Replaced the sensor but still happening every few days! Help! Dealer knows nothing.

    Getting there
    There is a thread on this issue somewhere on here (3rd gen forum I think.) A few guys have had this issue. Can't remember what the solution is/was. I think most had a re-flash of the ECM or PCM that solved it. I know they had some headache with getting it diagnosed and fixed because it never stored a code. If I find the thread, I'll link it.

    Welcome to the club! I had my sensor replaced at 1,000 miles , at 3,000 miles its come on once during a heavy downpour , read threads and follow the tips from us that have gone through this , take pictures , lots of pictures to show the mileage intervals with the light being on and off. Stand your ground and they should make it right.....good luck!

    I brought my truck in to the dealer for this issue.They could not duplicate and sent me on my way. Will make sure to take a pic if/when it happens again.
