What's wrong?
The rear outer wheel lug nuts on these 2017-2020 Npr Hd, Npr Xd, Nqr, Nrr, 4500HD, 5500HD, 4500XD, and 5500XD trucks clamp the wheel firmly to the rear axle. The lug nuts thread onto wheel studs and hold the wheel flat against the hub so it stays centered under load.
On affected trucks, the outer rear wheels were installed during final port processing in the United States. At the Baltimore port facility, some lug nuts were not tightened to the required torque, which means they started service without the clamping force the wheel needs. As the truck is driven, loose lug nuts can back off farther and allow the wheel to move against the hub.
Owners have noticed the problem at low mileage when one or more lug nuts are missing. If the truck keeps being driven as the lug nuts loosen, the loose hardware and wheel generate considerable noise.
Who's affected?
Spans eight Isuzu and Chevrolet truck models across four model years, all tied to the same wheel fastener component.

What's the safety risk?
Loose rear outer wheel lug nuts can let a wheel separate from the vehicle, increasing the risk of a crash. A missing lug nut or considerable wheel noise is a warning sign. If you notice either, stop driving and call an Isuzu dealer for inspection. Repair is free at any franchised Isuzu dealer.
What should I do?
- Check your VIN to confirm your 2017-2020 Isuzu Npr Hd, Npr Xd, Nqr, Nrr, Chevrolet 4500HD, 5500HD, 4500XD, or 5500XD is included in this recall.
- Contact a franchised Isuzu dealer to schedule the free rear outer wheel lug-nut inspection and repair.
- Ask the dealer to tighten or replace the rear outer wheel lug nuts so the wheel is secured to the rear axle.
- Bring the recall notice if Isuzu has mailed one. If not, reference recall number 19V835 when you call.
- Drive carefully until the inspection is complete, and stop driving if a rear wheel feels loose or the truck pulls, shakes, or makes unusual wheel noise.
What happens at the repair
At the dealer, an Isuzu technician inspects the rear outer wheel lug nuts, then tightens or replaces any lug nuts that were not properly secured. The inspection, parts, and labor are free under the recall. Isuzu has a general reimbursement plan on file for this campaign. If you already paid out of pocket for a related rear wheel lug nut repair, contact Isuzu customer service and ask what documentation the plan requires.
