Potential Number of Units Affected 25,018

 

Throttle may Stick in the Open Position

A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death.

 

Summary

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain model year 2014-2016 Isuzu NPR and NPR HD vehicles manufactured August 26, 2013, to November 11, 2016, and 2016 Chevrolet Low Cab Forward 3500 and 4500 vehicles manufactured July 27, 2016, to November 11, 2016.

The affected vehicles have a throttle pedal that may get stuck under the steel stopper bolt, causing the pedal to remain in the full throttle position.

Note: In gasoline models only.

 

Remedy

Isuzu will notify owners, and dealers will remove and replace the stopper bolt with a flanged plate, to prevent lateral movement of the throttle, free of charge.

The recall began November 14, 2016.

Owners may contact Isuzu customer service at 1-866-441-9638.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

SERVICE INFORMATION                                                                                                              

CONDITION

Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in Model Year 2014-2016 Isuzu N-Series vehicles equipped with 6.0L gasoline engines. In the affected vehicles, the accelerator pedal assembly contains a steel stopper plate that is intended to stop the depression of the pedal when the plate contacts the stopper bolt that is fixed to a bracket on the floor panel. As a result of unintended lateral play, the stopper plate can be forced under the outer ridge of the stopper bolt, causing the accelerator pedal to remain in the open position. An open throttle can increase the risk of a crash.

CORRECTION Dealers are to remove the stopper bolt and install a Stopper Bracket Assembly.

 

VEHICLES INVOLVED

Involved are Model Year 2014-2016 Isuzu N-Series vehicles equipped with 6.0L gasoline engines.

Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Isuzu Vehicle Inquiry System (IVIS). Not all vehicles may be involved.

    

PARTS INFORMATION

Parts orders may be placed with American Isuzu Parts Distribution Network (AIPDN). Please refer to your “involved vehicles listing” before ordering parts. Normal orders should be placed on a Stock Order. In an emergency situation, parts should be ordered on a VOR (Vehicle Off Road) Order.

SERVICE PROCEDURE

  2. Tighten the two (2) accelerator pedal mounting nuts (see Figure 1) to 18 Nm (13 ft. lb.).

  1. Temporarily install and hand tighten the new stopper bracket using the new bolt provided (see Figure 3). When tightened (even by hand), the head of the new mounting bolt should be below the flat surface of the new stopper bracket.  Be sure the stopper bracket is aligned properly (see Figure 4).

  1. Depress the accelerator pedal to WOT (wide open throttle) position. If the stopper plate does not contact the stopper bracket, the stopper bracket may require some adjustment.

a. If the stopper plate contacts the stopper bracket, torque the mounting bolt to 22Nm (16 ft. lb.) and go to Step 7.

b. If the stopper plate does not contact the stopper bracket, check the clearance by depressing the pedal to WOT and attempting to insert one of the washers provided with the stopper bracket between the stopper plate and the stopper bracket (see Figure 7).

I. If the washer does not fit between these two parts, the clearance between the stopper plate and stopper bracket is less than 2mm and no adjustment is necessary. Torque the mounting bolt to 22Nm (16 ft. lb.) and go to Step 7.

II. If the washer does fit between these two parts, remove the stopper bracket and add the washer between the stopper bracket and the floor (see Figure 8), and reinstall. This will adjust the clearance.  Check the clearance again by repeating Step 6 with the second washer and follow the results.

III. If both washers are installed and the clearance between the stopper plate and stopper bracket is less than or equal to 2mm, no further adjustment is necessary. Torque the mounting bolt to 22Nm (16 ft. lb.) and go to Step 7.

IV. If both washers are installed and the clearance between the stopper plate and stopper bracket is greater than 2mm, there is another problem with the vehicle. Follow the appropriate service manual for diagnosis.

  1. Connect IDSS, turn the key ON/engine OFF, and navigate to the engine control module data list to confirm “Accelerator Pedal Position (APP) Indicated Angle” parameter is at 100% during WOT (see Figure 9).

a. If the parameter is at 100%, continue to Step 8.

b. If the parameter is not at 100%, repeat Step 6 and recheck with IDSS. If the parameter continues to not be at 100%, and there is proper contact between the accelerator pedal and the stopper bracket, you may have incorrectly installed washers. Repeat Step 6 to confirm it was performed correctly. If these steps were performed correctly and the parameters still do not reach 100%, there is another problem with the vehicle. Follow the appropriate service manual for diagnosis.
