What the defect is
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.
What could happen
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.
What gets fixed
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.

Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 19 March 2021.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.
Additional 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.
Check your own vehicle
This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
