NHTSA recall 94V004000
Engine And Engine Cooling · Mercedes-Benz USA, LLC
Details
What's wrong: High ambient engine compartment temperatures are experienced after the vehicle is operated and then parked. If the vehicle is restarted a short time later and the charcoal canister is saturated with fuel, it is possible that fuel vapor may be expelled through the inlet vent line of the canister onto the electric auxiliary radiator fan preresistor.
Why it matters: Under certain operating conditions the electric auxiliary radiator fan preresistor becomes hot enough to ignite the fuel expelled from the charcoal cannister and result in an underhood fire.
The fix: Dealers will reposition the fuel vapor canister vent line away from the electric fan preresistor. In addition, the preresistor will have a larger heat shield and a fused wiring harness will be installed.
