The 2004 GMC Savana has 4 recalls, the most serious being two tied issues: unused rear HVAC wiring that can corrode and overheat, raising the risk of a vehicle fire, and a transmission shift cable that can separate and cause the van to move in an unintended direction.
On the electrical side, this recall applies to cutaway models equipped with wiring for an optional rear heating and air conditioning system. When that system is not installed and the connectors are left exposed, the blower motor circuit can corrode over time, overheat, and potentially ignite. The transmission concern is separate: a shift cable assembly can break apart, leaving the column shifter and the actual gear the transmission is in out of sync with each other. A driver who believes the vehicle is in park may find it rolling in reverse or forward without warning.
Both remaining recalls address the same front seatbelt buckle defect. The buckle latch can become brittle and crack under the load of a crash, failing to hold the belt in place at the moment it matters most. An occupant who appears properly buckled may not actually be restrained when the vehicle decelerates rapidly in a collision, increasing the chance of serious injury.
