What's wrong?
The molded hood mirror on 2022-2023 Peterbilt 579 trucks is the exterior mirror mounted on the hood to help the driver see along the side of the truck and reduce blind spots. It pivots at a joint so the mirror can be positioned and hold that position while the truck is moving.
On affected trucks, molding flaws in that pivot joint can let the mounting hardware back out or let the molded stem break. Once the joint gives way, the mirror assembly no longer stays attached as designed. Trucks built before the assemblies included a wire harness or tether have less backup retention, so a broken mirror can drop from the hood and fall into the roadway.
There is no warning sign before failure. If the pivot joint breaks, the first thing the driver notices can be the mirror loosening, separating from the hood, or missing from its normal position.
Who's affected?
The same molded hood mirror assembly is involved for the 2022 and 2023 trucks.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
A hood mirror that separates and falls into the roadway can become a hazard for other drivers, increasing the risk of a crash. There is no prior warning before the mirror falls, so schedule the inspection soon and treat any missing hood mirror as a reason to call the dealer before another trip. Repair is free at any franchised Peterbilt dealer.
What should I do?
- Check your VIN to confirm your 2022-2023 Peterbilt 579 is included in this recall.
- Contact your nearest franchised Peterbilt dealer to schedule the free hood-mirror inspection and replacement that secures or replaces mirror assemblies that can break at the pivot joint.
- Bring the recall notice if Peterbilt mailed one. If not, reference recall number 22V940 when you call.
- Avoid driving with a broken or unsecured hood mirror assembly; a mirror that falls into the roadway is a crash risk.
What happens at the repair
At the dealer, a Peterbilt technician inspects the hood mirror assembly for a wire harness or tether. If the mirror assembly is not properly secured, the technician replaces the hood mirror assembly as needed. The recall repair is free, with parts and labor covered. If you paid out of pocket for the same hood mirror problem before receiving the recall notice, Peterbilt's general reimbursement plan gives you a way to claim documented costs. Bring repair invoices, receipts, and any related paperwork to the service desk or contact Peterbilt customer service for the reimbursement process.
