What's wrong?
The outside rearview mirror on 2020 Hino NJ8J, NV1A, NH1A, TH1A, NV8J, and NE8J trucks uses mirror glass bonded to a carrier plate. The carrier plate holds the glass in the correct position so the driver has a stable view along the side and rear of the truck. That bond has to stay tight through vibration, weather, and normal road use.
On affected trucks, the carrier plate did not get the proper plasma treatment before the mirror glass was installed. That treatment prepares the surface so the adhesive grips correctly. Hino traced the problem to reduced flame temperature during the supplier process, caused by an oxygen flow leak. With weak adhesion, the mirror glass separates from the carrier plate.
There is no warning sign before failure. The mirror glass separates when the bond lets go, so the first sign is the glass loose, shifted, or missing from the mirror housing.
Who's affected?
Spans six Hino truck model lines from the 2020 model year, all using the same mirror glass carrier plate assembly.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Detached mirror glass reduces driver visibility or becomes a road hazard for other drivers, increasing crash risk. There is no warning sign before the mirror glass separates, so schedule the inspection soon and use extra care checking traffic around the vehicle. Repair is free at any franchised Hino dealer.
What should I do?
- Check your VIN to confirm whether this recall includes your 2020 Hino NJ8J, NV1A, NH1A, TH1A, NV8J, or NE8J.
- Contact a franchised Hino dealer to schedule the free mirror inspection and replacement that fixes mirror glass that can detach from the carrier plate.
- Bring the recall notice if you have it, and reference recall number 21V146 and Hino recall M0340 when you call.
- Drive with extra care until the mirror is inspected or replaced, and stop using the vehicle if mirror glass is loose or missing.
What happens at the repair
At the dealer, a Hino technician checks the mirror production date to see whether the mirror glass is from the recalled production group. If it is, the technician replaces the mirror at no charge. Parts and labor are covered under the recall. Owners who already paid for repairs tied to this mirror glass defect can request reimbursement from Hino. Include paid receipts with the request, since Hino says parts, labor, and related miscellaneous costs are eligible for review.

What should I do if my 2020 Hino NJ8J, NV1A, NH1A, TH1A, NV8J, or NE8J is on this recall?
Check your VIN to confirm your specific Hino vehicle is included in recall 21V146. If it is, contact a franchised Hino dealer to schedule the mirror inspection. The dealer will check the mirror production date and replace the mirror if needed.
