The 2019 Chevrolet Silverado 5500 has two recalls, both carrying fire risk: one tied to the optional engine block heater on diesel-equipped trucks, and one involving a brake pressure sensor that can leak fluid and cause an electrical short.
On diesel models with the optional block heater, a short circuit can damage engine components and start a fire. Separately, the brake pressure sensor assembly can leak brake fluid into the brake pressure switch, where it causes an electrical short that can overheat the circuit and lead to a fire whether the truck is moving or parked.
