Recall history
3 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
20V244000 · Electrical System:12v/24v/48v Battery:Cables
Reported: 2020-04-30 (April 30, 2020)
Hino Motors Sales U.S.A., Inc. (Hino) is recalling certain 2020-2021 NV8J, NJ8J, NE8J, NJ8A, NV8A, NE8A, NE8G, NJ8C, NE8C, and NV8G trucks. The ground cable that connects the negative battery terminal to the frame may be too short and may break as a result.
Consequence: If the ground cable breaks, the engine cannot be re-started to move the vehicle to a safe area, increasing the risk of a crash.
Remedy: Hino will notify owners, and dealers will install an extension bracket to the negative battery terminal and inspect the ground cable terminal for damage, replacing the cable if damage is found, free of charge. Owners will be notified of the safety risk with an interim letter Mid-June 2020. The recall began June 26, 2020. Owners may contact Hino customer service at 1-248-699-9390. Hino's number for this recall is AAHT0.
NHTSA campaign record ↗20V383000 · Service Brakes, Air:Antilock:Control Unit/Module
Reported: 2020-07-01 (July 1, 2020)
Hino Motors Sales U.S.A., Inc. (Hino) is recalling certain 2021 NJ8A low-profile heavy trucks equipped with a full air brake system. The Anti-Lock Braking System control unit (ABS ECU) may be programmed with incorrect datasets for the tone ring teeth, causing the anti-lock braking system to mistakenly detect a difference between front and rear wheel rotation speeds resulting in deactivation of the Anti-Lock Braking function. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
Consequence: A loss of ABS function can increase the risk of a crash.
Remedy: Hino will notify owners, and dealers will reprogram the ABS-ECU with the corrected software. The recall began August 25, 2020. Owners may contact Hino customer service at 1-248-699-9390. Hino's number for this recall is AAJS0.
NHTSA campaign record ↗22V021000 · Service Brakes, Air:Supply:Hoses, Lines/Piping, And Fittings
Reported: 2022-01-21 (January 21, 2022)
Hino Motors Sales U.S.A., Inc. (Hino) is recalling one 2021 NJ8A vehicle. The end fittings on the replacement air brake hose assembly may not have the manufacturer designation. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 106, "Brake Hoses."
Consequence: The air brake hose end fitting may not be traceable should there be a safety recall, increasing the risk of a crash, injury, or fire.
Remedy: A dealer will replace the air brake hose, free of charge. Owners may contact Hino customer service at 1-248-699-9390. Hino's number for this recall is AANT0.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
