PACCAR is recalling 3,907 2020 Peterbilt and Kenworth trucks under recall 19V340 because the mirror glass can detach from the carrier plate due to inadequate adhesion.

What's wrong?
The exterior rearview mirror on these Peterbilt and Kenworth trucks is the large glass panel mounted to the cab that lets the driver see traffic alongside and behind a tractor that can run more than 70 feet long with a trailer. The glass is bonded to a plastic carrier plate, and that carrier clips into the mirror housing on the door. The bond between glass and carrier is what keeps the mirror flat, aimed, and usable at highway speed.
On affected trucks, the adhesive that holds the glass to the carrier plate did not cure correctly at the supplier. A leak in the oxygen flow on the heating equipment lowered the flame temperature, so the parts never reached the heat needed for a full bond. The glass can separate from the carrier and hang down inside the housing, blocking the lower convex mirror and the view of nearby lanes.
There is no warning sign before failure. The first sign is often the glass shifting or dropping out of position during a normal drive.
Who's affected?
Covers five PACCAR-built Class 8 truck models across the Peterbilt and Kenworth brands, all built in a four-week window and sharing the same exterior mirror assembly.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included in this recall.
What's the safety risk?
If the upper mirror glass detaches, the driver loses part of their rearward view and the loose glass becomes a road hazard that can strike another vehicle or a pedestrian, raising the risk of a crash or injury. Schedule the repair soon and inspect both mirrors before each trip until the dealer completes the work. Repair is free at any franchised Peterbilt dealer.
What should I do?
- Check your VIN to confirm your 2020 Peterbilt or Kenworth truck is included in this recall.
- Contact your nearest franchised Peterbilt or Kenworth dealer to schedule the free mirror inspection and glass replacement that fixes the detachment-prone upper mirror.
- Reference recall number 19V340 when you call, and mention PACCAR's internal number (19PBC for Peterbilt, 19KWC for Kenworth) so the service desk pulls the correct work order.
- Call PACCAR customer service with questions: Peterbilt owners at 1-940-591-4220, Kenworth owners at 1-425-828-5888.
- Inspect the upper mirror glass before each trip until the repair is complete, and avoid driving in heavy traffic or at highway speeds if the glass shows any sign of separation from the carrier plate.
What happens at the repair
At the dealer, a Peterbilt technician inspects the upper mirror glass and the mirror carrier plate, then replaces the assembly if the adhesion is inadequate. Parts and labor are free under the recall. If you have already paid out of pocket for a related mirror repair, PACCAR's standard reimbursement plan covers documented expenses. Bring your receipts and any prior repair paperwork to the service desk when you arrive. Kenworth owners can reach PACCAR customer service at 1-425-828-5888, and Peterbilt owners can call 1-940-591-4220.
