The 2019 Chevrolet Silverado 4500 has 3 recalls, two of which involve fire risk: an engine-block heater short circuit on diesel-equipped trucks and a brake pressure sensor that leaks fluid into an electrical switch and can overheat the circuit whether the truck is moving or parked.
The third recall involves the power brake assist system. A previous repair attempt for a brake issue used a wiring harness assembled without protective tape, leaving the wires exposed to damage. If those wires are damaged, the power brake assist can fail, requiring significantly more pedal force to slow the truck and raising the risk of a crash.
