What's wrong?
The charge pipe flare nut is the fastener that seals and secures the air compressor delivery pipe on the 2022 Hino NJ7A. The air compressor builds pressure for the truck's air brake system, and the delivery pipe carries that compressed air into the system. Air brakes depend on that connection staying tight so the system can hold steady pressure.
On affected trucks, the flare nut attached to the air compressor was not tightened properly during assembly. Hino traced the problem to a missing standard work step for confirming torque on that nut. If the nut loosens, air can leak from the connection and system pressure can drop. With low air pressure, the parking brake can automatically apply if the driver ignores the warnings.
Owners have warning signs before failure. The air pressure gauges show the low-pressure condition, the warning light illuminates, and an audible alarm sounds when pressure drops. Treat those warnings as evidence the brake air system is losing pressure, not as a normal startup alert.

Not every 2022 Hino NJ7A truck is on the list. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Low air pressure can make the parking brake apply automatically, increasing the risk of a crash. If the air gauges show low pressure, or the warning light and audible alarm activate, slow down, stop safely, and arrange service. Repair is free at any franchised Hino dealer.

- Call Hino customer service at 1-248-699-9390 with questions about recall M0360.

Frequently asked questions
What is recall 22V128?
Recall 22V128 covers 141 2022 Hino NJ7A vehicles with a charge pipe flare nut on the air compressor that was not tightened properly. That condition can lower air pressure and cause the parking brake to apply automatically, increasing crash risk. Hino dealers will tighten the nut for free.
What should I do if my 2022 Hino NJ7A is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 22V128. If it is, contact a franchised Hino dealer to schedule the charge pipe flare nut tightening. Reference recall number 22V128 or Hino recall M0360 when you call. The repair is free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to perform the recall repair at no cost, and Hino's remedy says dealers will tighten the charge pipe flare nut free of charge at any franchised Hino dealer.
What is the safety risk?
The safety risk is an automatic parking brake application from low air pressure. If the charge pipe flare nut is loose, the air system can lose pressure, and the parking brake can apply without the driver choosing it. That increases crash risk.
When were owners notified about recall 22V128?
Hino mailed owner notification letters on March 28, 2022. If you bought the NJ7A used or never received a letter, the VIN check is still the right way to confirm whether this recall applies to your specific vehicle.
