AFFECTED VEHICLES: Certain 2022 Outlander vehicles

 

PURPOSE

A recall campaign will be released today for the replacement of the fuel pump with a countermeasure part on certain 2022 Outlander vehicles built after July 2021. The Recall Bulletin outlining the repair procedure will be available today on MEDIC and MDL.

The commutator and wires in the fuel pump may not have been fused together correctly during production, resulting in poor continuity. As a result, the commutator and the brushes in the fuel pump could wear abnormally in use, causing the fuel pump to be inoperative. If the fuel pump does not operate, the engine may stall while driving, which increases risk of a crash.

Notification letters are scheduled to begin mailing to owners of affected vehicles on March 18, 2022, requesting they contact their local Authorized MitsubishieBay logo dealership to schedule an appointment to have this recall performed.

A very limited number of parts are currently available, and an initial allocation of parts in inventory will be made to dealers. An additional allocation will be made at the time of customer notification which is anticipated to be mid-March 2022. No other parts are currently available for order.

Affected new vehicle inventory VINs can be reviewed on the MitsubishieBay logo Dealer Link in the Most Recent: Open Campaign List available under the service section of “e-reports.” Dealers must review the Warranty Superscreen to confirm if any vehicles in their new or used vehicle inventories are affected and complete this campaign prior to delivering them. When checking for the applicability of this campaign (C2201R), please check for and complete any other open campaigns. Always obtain the customer’s approval before completing a campaign on a customer-owned vehicle.

 


PURPOSE

This campaign bulletin instructs dealers to replace the fuel pump with a countermeasure part.

 

BACKGROUND

The commutator and wires in the fuel pump may not have been fused together correctly during production, resulting in poor continuity. As a result, the commutator and the brushes in the fuel pump could wear abnormally in use, causing the fuel pump to be inoperative. If the fuel pump does not operate, the engine may stall while driving, which increases risk of a crash.

 

AFFECTED VEHICLES

Certain 2022 Outlander vehicles

 

IMPORTANT

Affected new or used inventory vehicles must be repaired before the vehicle is sold/ delivered. Dealers must check their inventory vehicles’ VINs on the Warranty Superscreen to verify whether the vehicle is involved in this recall campaign. It is a violation of Federal law for a dealer to sell/deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by the notification under a sale or lease until the defect or noncompliance is remedied.

 

CUSTOMER NOTIFICATION

A letter will be sent to all owners of affected vehicles telling them to visit their local Authorized MitsubishieBay logo Motors dealer to have the fuel pump replaced. A copy of the customer notification letter appears at the end of this bulletin.

PRECAUTIONS

WARNING

When replacing fuel line parts, be sure to observe the following.

  • Put a “CAUTION: FLAMMABLE” sign in the workshop.
  • Be sure to work in a well-ventilated area and furnish the workshop with a CO2 fire extinguisher.
  • Never smoke while servicing the fuel system. Keep open flames and sparks away from the work area.

 

CAUTION

  • Use gasoline required by the regulations for octane numbers.
  • Before removing fuel line parts, perform the following procedures:

① Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in a safe area.
② Release fuel pressure from the fuel lines. Refer to Repair Procedure.
③ Disconnect the battery cable from the negative terminal.

  • Always replace O-ring and clamps with new ones.
  • Never bend or twist tubes when they are being installed.
  • Never tighten hose clamps excessively to avoid damaging hoses.
  • After installing tubes, check that there is no fuel leakage at connections in the following steps.

① Apply fuel pressure to fuel lines by turning the ignition switch “ON” (with the engine stopped). Then check for fuel leakage at connections.
② Start the engine and rev it up and check for fuel leakage at connections.

 

REPAIR PROCEDURE

1. Release fuel pressure

a. Release fuel pressure from the fuel lines.

1) Remove fuel pump fuse inside the engine compartment (Fuse No. 85).
2) Start the engine.
3) After engine stalls, crank two or three times to release all fuel pressure.
4) Turn ignition switch OFF

 

WARNING

  • DO NOT reinstall the fuel pump fuse until after the fuel pump is installed.

 

b. Preparation before disconnecting the battery cable from the negative terminal.

1) To make room for the repair work, slide the front seat forward.
2) Open the liftgate for gas smell ventilation.
3) Insert a fuel filler funnel in the fuel filler cap and release the pressure inside the fuel tank. A fuel filler funnel can be found inside the Cargo floor are (see below).
4) After using the fuel filler funnel return it to its storage area (see below).

 

c. Disconnect battery negative terminal.

 

WARNING

  • With the adoption of the Auto ACC function, ACC power is automatically supplied by operating the Intelligent Key or remote keyless entry or by opening/closing the driver side door.
  • In addition, ACC power is supplied even after the ignition switch is turned to the OFF position, i.e. ACC power is supplied for a certain fixed time.
  • When disconnecting the 12V battery terminal, turn off the ACC power before disconnecting the 12V battery terminal, observing “How to disconnect 12V battery terminal” described below.

① Turn the ignition switch to the ON position.
② Turn the ignition switch to the OFF position with the driver’s side door opened.
③ Get out of the vehicle and close the driver’s side door.
④ Wait at least 3 minutes. (This avoids activating the security alarm.)

CAUTION

  • While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of this caution results in the activation of the ACC power supply according to the Auto ACC function.

⑤ Remove the battery negative terminal and apply tape to the battery terminal to avoid connection until the repair is complete.

CAUTION

When re-installing the battery terminal at the completion of the repair, always check the self-diagnosis results of all ECUs and erase DTCs.

d. Pull the second row seats up.
