"Park outside": Carmaker recalls 40,000 vehicles to fix fire risk

General Motors is recalling certain Chevrolet Silverado medium-duty trucks for model year 2019 or later, following the discovery of a potential leak in brake fluid that could result in a fire.

Potentially 40,428 vehicles could be affected.

They include 4500HD, 5500HD, and 6500HD models with model years between 2019 and 2023, according to documents posted by U.S. Safety regulators on Saturday.

The vehicles may have a brake pressure sensor assembly that allows brake fluid to leak and cause a short circuit.

That in turn increases the risk of a fire that could occur when the vehicle is either driving or parked.

GM advises owners with potentially affected models to park outdoors and away from structures until the recall repair is done. Vehicles with model years before 2019 used a different design.
