Manufacturer Isuzu Technical Center of America, Inc.
Components ENGINE AND ENGINE COOLING, ELECTRICAL SYSTEM
Potential Number of Units Affected 46
Summary
Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2020 NPR-HD (Crew Cab) and Chevrolet 4500 (Crew Cab) vehicles equipped with 6.6L gasoline engines.

Isuzu will notify owners, and dealers will install additional retention parts (1 band tie, 1 clip, and 1 edge protector) to ensure adequate clearance between the surge hose and chassis harness, free of charge. The recall is expected to begin December 28, 2020. Owners may contact Isuzu customer service at 1-866-441-9638. Isuzu’s number for this recall is V2006.

STOP SALE AND DELIVERY – SAFETY RECALL
Date: November 20, 2020
Subject: Stop Sale and Delivery for Upcoming Safety Recall
Affected Models:
- Certain 2020MY N-Series Crew Cab Vehicles with Gasoline Engines 6.6 L8T
To: Isuzu Dealer Principal, Sales Manager and Service Manager
Effective immediately, stop the sale and delivery of affected vehicles in your inventory, even if a customer has purchased an affected vehicle. We are in the process of taking steps to address a safety related defect in these vehicles. Federal law prohibits the sale and delivery to customers of any vehicle containing a safety defect. You must not deliver any covered vehicles to customers until after the vehicle has been remedied.
WHAT IS THE CONDITION
Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in certain 2020MY N-Series crew cab vehicles with gasoline engines 6.6 L8T. In the affected vehicles, the chassis harness and the coolant return hose from the radiator to the reservoir (surge hose) are located near the edge of the cab floor panel. During normal driving, the harness and/or hose could potentially chafe from contact with the cab floor panel. Continued chafing could cause wear in the harness and/or hose, ultimately causing a hole in the hose with the potential for engine coolant to leak and/or causing damage to the harness with the potential for a short circuit. Leaking engine coolant and/or a damaged wire harness may result in a no-start condition, engine stall, or thermal event, increasing the risk of a crash or fire.
WHAT WE WILL DO
Isuzu Commercial Truck of America, Inc. has issued this notice and, if applicable, an affected inventory report (approximately 24 vehicles are in dealer inventory). On Monday, November 23, 2020, dealers with affected vehicles will be force-shipped an initial quantity of remedy parts and the campaign bulletin will be published.
WHAT YOU SHOULD DO
After confirming there are affected vehicles in your dealer’s inventory, using the Isuzu Vehicle Information System (IVIS), open a repair order referencing this Stop Sale for each affected NEW vehicle in your inventory and hold the vehicle until the campaign bulletin is released.
IMPORTANT: Always confirm vehicle eligibility prior to beginning repairs by using the Isuzu Vehicle Information System (IVIS).
You will receive information about owner notification in the near future.
We regret any inconvenience this action may cause you.
Sincerely,
