“The ABS/HCU module has experienced a premature failure which is a huge safety risk as it controls my vehicles' Anti-lock Braking System, Traction Control & Cruise Control systems. Since experiencing this failure, my vehicle has had numerous safety incidents where Braking would lockup, traction with the roadway is lost etc. Please initiate a recall for this issue for these generation of trucks so this safety issue can be addressed.”
