Recall history

5 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.

15V778000 · Equipment

Reported: 2015-11-20 (November 20, 2015)

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2012-2016 NPR, NPR-HD, NPR-XD, NQR, and NRR diesel trucks manufactured November 24, 2011, to July 24, 2015, and 2012-2015 NPR and NPR-HD gasoline-powered trucks manufactured October 5, 2011, to August 27, 2015. The trucks may have been equipped with certain Kidde plastic valve disposable handheld fire extinguishers, model FC10, that may not properly discharge when the lever is pressed.

Consequence: In the event of a fire, if the fire extinguisher does not work correctly, there is an increased risk of injury.

Remedy: Isuzu will notify and instruct owners to order replacement fire extinguishers free of charge directly from Kidde Safety at www.kidde.com, or toll-free at (855)283-7991, or by contacting and visiting a dealer. The recall began on January 18, 2016. Owners may contact Isuzu customer service at 1-866-441-9638.

16V797000 · Vehicle Speed Control:Accelerator Pedal

Reported: 2016-11-02 (November 2, 2016)

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.

Consequence: 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.

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.

17V191000 · Power Train:Axle Hubs

Reported: 2017-03-21 (March 21, 2017)

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2011-2016 NPR, 2011-2017 NPR-HD, NQR, NRR, 2015-2017 NPR-XD, 2012-2016 Reach, NPR Gas and NPR-HD Gas incomplete trucks. The left rear wheel bearing hub locking bolts may not have been properly tightened during assembly.

Consequence: The loose bolts can allow the wheel assembly to move outward from the axle housing, affecting the control of the vehicle and reducing braking performance, thereby increasing a risk of a crash.

Remedy: Isuzu will notify owners, and dealers will inspect the left rear wheel bearing hub locking bolts, tightening them as necessary, free of charge. The recall began on April 19, 2017. Owners may contact Isuzu customer service at 1-866-441-9638.

17V726000 · Equipment

Reported: 2017-11-14 (November 14, 2017)

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2011-2017 Isuzu NPR, 2008 NPR HD and NPR-HD Gas, 2011-2018 NPR HD and NRR, 2015-2018 NPR XD, 2012-2018 NQR, 2012-2017 NPR Gas and NPR-HD Gas, 2016-2017 Chevrolet Low Cab Forward 3500 HD, 3500 and 4500 and 2017-2018 Chevrolet Low Cab Forward 4500 HD, 4500 XD, 5500 HD and 5500 XD vehicles, equipped with certain Walter Kidde Plastic-Handle Fire Extinguishers, models FC10 and FC110. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable.

Consequence: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.

Remedy: Isuzu will notify owners, instructing them to contact Kidde to get a replacement fire extinguisher, free of charge. The recall is expected to begin in December 2017. Owners may contact Isuzu customer service at 1-866-441-9638 or Walter Kidde customer service at 1-855-262-3540 or they may also visit www.kidde.com and click on "Product Safety Recall" to order replacement fire extinguishers free of charge. Isuzu's number for this recall is V1705. Note: This recall includes fire extinguishers provided as a remedy for previous Isuzu recall 15V778.

21V194000 · Suspension:Rear:Springs:Leaf Spring Assembly:U-Bolt, Leaf Spring To Axle

Reported: 2021-03-19 (March 19, 2021)

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2015-2017 Isuzu NPR, Reach, 2016-2020 Isuzu NPR XD, NPR HD, NQR, 2016-2021 Isuzu NRR, 2017-2020 Chevrolet 4500XD, 4500HD, 5500HD, and 2020 Chevrolet 5500XD vehicles. The U-bolt nuts for the rear axle may not have been properly tightened and may loosen, causing the axle to misalign.

Consequence: The misalignment may cause the propeller shaft to separate, causing a loss of power to the rear wheels and a stall, increasing the risk of a crash.

Remedy: Isuzu will notify owners, and dealers will inspect and, if needed, replace and tighten the rear axle U-bolt nuts, free of charge. The recall began on April 23, 2021. Owners may contact Isuzu customer service at 1-866-441-9638. Isuzu's number for this recall is V2103.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.
