Read full bulletin
General Motors has decided to conduct a Voluntary Emission Recall involving certain 2015- 2016 model year Chevrolet Trax vehicles. The mounting ring for the fuel pump module may be improperly molded into the plastic fuel tank shell. Vehicles built with this defect have the potential to develop small liquid fuel leaks or fuel vapor leaks at the top of the tank. Customers may notice an odor of unburned fuel or visible traces of condensed liquid fuel in the area of the fuel tank that develop over time. Vehicles equipped with enhanced evaporative emissions equipment will declare this condition in the form of a check engine malfunction indicator light. Dealers are to install a new fuel tank assembly.

15602 - Emission Recall.
Read full bulletin
General Motors has decided to conduct a Voluntary Emission Recall involving certain 2015 - 2016 model year Chevrolet Trax vehicles. The mounting ring for the fuel pump module may be improperly molded into the plastic fuel tank shell. Vehicles built with this defect have the potential to develop small liquid fuel leaks or fuel vapor leaks at the top of the tank. Customers may notice an odor of unburned fuel or visible traces of condensed liquid fuel in the area of the fuel tank that develop over time. Vehicles equipped with enhanced evaporative emissions equipment will declare this condition in the form of a check engine malfunction indicator light. Dealers are to install a new fuel tank assembly.

Engine Soon Malfunction Indicator Lamp. Technician may find Diagnostic Trouble Code P0442. Technician will need to review Techlink article from May 2013 titled "Using the Evaporative Emissions System Tester" Technician will need to follow these steps to help diagnose the issue. First after the P0442 has been verified do not disturb any of the fuel system components. The technician now can use the scan tool to close the Evaporative Emissions System. If possible change the tank pressure sensor units from inch_H2O to milimeter_Hg for better resolution. Now the vehicle can be stared to monitor the tank pressure sensor output value for approximately two minutes. If the tank pressure sensor value does change, pressurize the fuel tank side of the purge solenoid with the GE 41413-A / J 41413-A and the necessary adaptors. Now add smoke and allow pressure to stabilize for 2 minutes. If smoke is allowed to pass through the purge solenoid, replace the purge solenoid. If the tank pressure sensor value does not change, then install CH-48096 adaptor between the purge line from the canister and the purge solenoid. With the Evaporative Emissions System closed, pressurize the system through the CH-48096 adaptor and allow the system to completely stabilize, by observing the Press / Vac Gauge for a minimum of 5 minutes. Now add smoke to the system with GE 41413-A / J 41413-A after system stabilization. Now inspect the purge solenoid, engine side, fuel cap, canister vent solenoid filter and any line quick connects. When the leak is unable to be located, test under a vacuum condition. his type of leak may be detected by using the scan tool Purge/Seal function to create a vacuum in the Evaporative Emissions System and then observe the FTP sensor parameter for vacuum decay.
