General Motors is recalling approximately 63,900 Cadillac XTS full-size sedans over a possible issue with the brake booster pump that can result in overheating, melting of components, and a possible engine compartment fire. The recall is part of GM’s just-completed comprehensive safety review resulting in three new recalls affecting 3.54 million vehicles.
The problem: a brake booster pump can create positive pressure within the wiring harness attached to the pump relay. This pressure can lead to the dislodging of a plug in the brake booster pump relay, allowing corrosive elements to enter the connector and form a low-resistance short that could lead to overheating, melting of plastic components, and a possible engine compartment fire.
In a news release, GM wrote that it is aware of two engine compartment fires in unsold vehicles at dealerships and two cases of melted components.
Affected vehicles: Cadillac XTS from the 2013 and 2014 model years.
Number of vehicles potentially affected: approximately 63,900.
The fix: GM didn’t specify the solution, but whatever it ends up being, it will likely involve replacing the brake booster pump.
