Service bulletin SA-035-26

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

DESCRIPTION When refueling, you may occasionally notice: A gurgling sound from the fuel filler neck. The gas dispenser nozzle clicks off before the tank is full. Fuel vapor or mist from the filler neck. This can occur if 20 minutes have elapsed after pressing the fuel lid button and the fuel tank has resealed the Vapor Recovery System (VRS) before refueling is complete. Before Refueling: 1. Press the fuel-filler lid opener switch. The system will release pressure in the tank through the vapor recovery system (charcoal canister) and enter Refueling Mode. You’ll see “Ready to Refuel” displayed on the instrument cluster. 2. You now have 20 minutes to complete refueling. After 20 minutes, or if the vehicle is turned to “READY ON,” the tank will automatically reseal the vapor recovery system. If the tank vapor recovery system has resealed, you may notice: The gas pump despenser clicks off before the tank is full. A gurgling sound from the filler neck. Fuel vapor or liquid may spit back from the filler neck. If this happens: 1. Press the fuel-filler lid switch again. 2. Wait until the instrument cluster displays “Ready to Refuel.” 3.Continue refueling.
