Not enough dated records to plot a meaningful trend — 1 month of data.
Complaints grouped by the component NHTSA recorded
Percentages are of component mentions. A single complaint can name more than one component, so these do not sum to the total complaint count.
No recalls in our database for this model year
That does not guarantee a specific vehicle is unaffected — recalls are issued against VINs, and new campaigns are announced regularly. Check a VIN on NHTSA.gov.

2011 – Current model year Hino Conventional and 2013 – 2020 model year Hino COE trucks equipped with reprogrammable control modules supported by the Hino Repro Server When reprograming a control module that is supported by the Hino Reprogramming server such as an Engine, Vehicle or Doser control module (ECU, VCS, DCU), the error below may be seen in DX3 when attempting to reprogram. This is typically the result of the VIN not being registered with the Hino Repro Server. This will require creation of an INF file via the DX3 and registering the file on the Hino Repro Server.
To improve the Emission Control System and On-Board Diagnostic (OBD) System, Hino will perform the modifications below: •Re-programming software for Engine Control Unit (ECU) and Dosing Control Unit (DCU) •Replacing NOx sensors, PM sensor, , Deisel Exhaust Fluid (DEF) sensor and Mass Air Flow (MAF) sensor •Replacing Tail Chamber and SCR Chamber •Replacing related harnesses

These updates apply exclusively to vehicles eligible for the Emissions Modification (Recall) under campaign codes AB5S0 or AB5R0.
AB5R0* CAMPAIGN KIT CONTENTS
Beginning the week of November 3, 2025, both HinoNet and Dealer Connect will be updated to reflect the Emissions Recall for eligible vehicles. During this period, recall work instructions will be published on HinoNet, and an initial shipment of recall parts kits will be distributed to dealers based on UIO/AOR data.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
Complaint and recall counts across every year of this model
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
