| Type | Statutory Recall (government-mandated recall) |
| Date filed | December 5, 2002 |

Defect
The air heater raises intake air temperature to improve cold-start performance. Due to either (1) insufficient waterproofing and rust protection of the air heater relay, or (2) insufficient waterproofing and rust protection of the air heater relay combined with an improperly programmed control unit, the air heater relay may remain continuously energized. In the worst case, the air heater overheats, scorching surrounding electrical wiring and causing a vehicle fire.
Corrective action
On all vehicles, confirm the vehicle type and replace the air heater relay with either (1) a corrected part incorporating waterproofing and rust-prevention measures, or (2) a corrected part incorporating revised contact material along with waterproofing and rust-prevention measures.
