“I am experiencing the exact problem that is described regarding the recall of Gmc light trucks for ABS activation at slow speeds due to corrosion of the hub and wheel assembly. I have a 2004 Gmc Sierra Denali which, according to Gmc, is not included in the massive recall prompted by your investigation. My issue, as described by the dealer, is exactly the same as the issue and reason for recalling those other vehicles.”

NHTSA complaint #10184356, filed 2007-03, 48,000 miles

“I was driving down route 24 in lewes, delaware approaching a yellow light when the car in front of me stopped. I applied the brakes and they completely failed despite putting the peddle all the way to the floor. I was forced to veer onto the shoulder then into a farmers field in order to slow the truck down enough to force it into park. Apparently the hydraulic brake lines on these trucks are completely exposed to the elements and have a history of failing. Once that happens, the rear calipers lock up and there are no brakes at all switch can cause a crash. …”
