One problem related to brake light on has been reported for the 2002 Ford F-150. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2002 Ford F-150 based on all problems reported for the 2002 F-150.
(1) without warning the brake light came on due to a failure of a hydraulic control unit, which would have ultimately lead to a failure of the abs system if it weren't for the awareness of the driver. The failure of the abs could have lead to an even greater catastrophe than just the cost of parts and labor. (2) it is my understanding through my research and the word of the service department at bozeman Ford dealership in bozeman, montana that this particular problem is not unheard of. In fact, it has become enough of a problem that Ford has made an attempt to correct the problem, by replacing the old hydraulic control unit with another hydraulic control unit, in addition to an electronic control unit and a bracket that mounts the two together. Although Ford has made an attempt to resolve the problem, they have not made any strides in issuing a recall for the faulty hcu. Instead of replacing a $300 part (which isn't even manufactured any more) three new parts are to be installed a price of nearly $1000 including labor. (3) the truck is currently at the dealership being repaired, and apparently we will be stuck with the entire cost of the larger figure above, simply because Ford does understand that there is in fact a problem with the hcu, but fails to accept any responsibility for it, by refusing to place the part under warranty or issuing a recall a the sub-par hydraulic control unit.
