Vehicle Speed Control:accelerator Pedal 2017-05-17 · campaign 17V324000 · 14,807 vehicles
Defect: Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain model year 2008-2009 and 2012-2013 Isuzu NPR and NPR HD vehicles and 2008-2009 GMC W3500 and GMC W4500 vehicles. The affected vehicles, equipped with a gasoline-powered engine, have a throttle pedal that may get stuck under the steel stopper bolt, causing the pedal to remain in the full throttle position.
Risk: 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.
Fix: 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 on June 23, 2017. Owners may contact Isuzu customer service at 1-866-441-9638.
