problem #2

I powered on the truck. Upon ignition check engine light, along with ABS, 4WD, traction control came on. Lights for the forward collision and adaptive cruise control illuminated. ABS system in the truck is no longer functioning causing the brake pedal to pulsate and lose pressure. Dealer diagnosed the troubleshooting codes and determined the ABS and the HCU (Hydraulic Control Unit) need to be replaced.

Brakes started grinding at 13,000 miles. Determined they were metal to metal, caliper, overheated, excessively, and rotor needed replaced. Problem happened again now, at 22,000 miles.
