- [18207 02](/bulletins/10212582.md), 2022-05-31, Service bulletin: POWER TRAIN; ENGINE AND ENGINE COOLING; WHEELS; FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY; STEERING:AUTOMATED/ADAPTIVE STEERING:MOTOR/ACTUATOR; STEERING; AIR BAGS. Customer Satisfaction. Certain vehicles may have a condition in which the power steering gear motor could separate from the steering gear housing due to corrosion of the attaching bolts. If the motor separates, power steering assist may be reduced or lost, and the driver may experience an unexpected increase in steering effort, especially at low speeds. Replace the bolts that attach the electric power steering motor to the steering gear and add a protective wax coating to each bolt and the seam around the electric power steering motor. If the bolts cannot be removed due to corrosion, the steering gear must be replaced. \*\* Revised Parts Information \*\*

This Preliminary information communicates that when removing the fuel line jumper hose care should be taken to be sure the line is reinstalled correctly to avoid a no/low fuel pressure situation.
- [PI0874](/bulletins/10138563.md), 2018-05-29, Service bulletin: FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY:FILLER PIPE AND CAP. This preliminary information bulletin provides a procedure on replacement of the fuel tank and fuel pipe vent hose for a concern of the malfunction indicator lamp illuminated and DTC P0454.
- [PIT4943D](/bulletins/10114954.md), 2017-08-15, Service bulletin: FUEL SYSTEM, GASOLINE; FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL. This Preliminary Information communication provides information to the technician about vehicles that have a Service 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.
- [PIC6030](/bulletins/10112256.md), 2017-08-15, Service bulletin: FUEL SYSTEM, GASOLINE; FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY:FILLER PIPE AND CAP. This Preliminary Information communication provides information to the technician about vehicles that may have check engine light on. Technician may find a Diagnostic Trouble Code P0442. Technician will need to inspect the fuel filler pocket rubber insulator to make sure it is not rolled over the fuel pipe neck.
