1 recall across 1 model year
The Pontiac Sunburst has 1 recall affecting the 1985 model year, where the fuel pump diaphragm can perforate and allow fuel to leak into the engine compartment, creating a fire risk that can spread to the passenger compartment without any warning beforehand.
When the diaphragm fails, raw fuel escapes the pump and contacts hot underhood surfaces. Because there are no advance symptoms, a fire can develop without the driver noticing anything wrong until it has already taken hold.
