2022-2024 Hino Trucks Recall 24V075: TCU Ground Overheat

Recall 24V075 affects 12,118 2022-2024 Hino trucks for an unsecured telematics ground connection that can overheat. Repair is free at any franchised Hino dealer.

What's wrong?

The telematics harness in affected 2022-2024 Hino trucks is a jumper wire harness for the telematics control unit, the electronic module that handles connected vehicle functions. The harness includes a ground path, which gives the module a stable return path for electrical current and helps the truck's electrical systems communicate cleanly.

On these trucks, the ground connection in that harness was not secured properly. Hino changed the telematics control unit design, and the revised housing ground was vulnerable when the harness was connected to the battery incorrectly. That weak ground connection can overheat. The repaired harness uses an isolated ground circuit to separate that path and prevent the same failure.

Before the failure, operators can see an ABS warning light or check engine light. The gauges can display incorrect information, stop lamps can stop working, the radio or air conditioning can stop operating, or the truck can refuse to shift into gear.

Who's affected?

Spans model codes from the Hino NM, NJ, NH, NE, NV, TH, and TM truck families across 2022-2024, all tied to the telematics jumper wire harness.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.

What's the safety risk?

An overheated ground connection can increase the risk of a fire. Warning signs include an ABS warning light, check engine light, incorrect gauge readings, inoperative stop lamps, loss of radio or air conditioning, or trouble shifting into gear. Park safely and contact a Hino dealer for inspection. Repair is free at any franchised Hino dealer.

What should I do?

1. Check your VIN to confirm your 2022-2024 Hino NE7A, NE7B, NH7A, NH9A, NH9B, NH9C, NJ7A, NJ7B, NJ7C, NV7A, NV7B, NV7C, NM9A, NM9B, TH9K, or TM9K is included in this recall.
2. Contact your nearest franchised Hino dealer to schedule the free telematics-harness ground-circuit repair.
3. Ask the dealer to inspect and repair the ground circuit and replace damaged harnesses, which fixes the loose ground connection that overheats.
4. Bring the recall notice if Hino mailed one. If not, reference recall number 24V075 when you call.
5. Call Hino customer service at (248) 699-9300 with questions about scheduling or owner notices.

What happens at the repair

At the dealer, a Hino technician inspects the telematics control unit harness ground circuit, repairs the ground connection, and replaces any damaged harnesses needed to correct the overheating concern. The recall repair is free, with parts and labor covered. Hino offers reimbursement for repair costs tied directly to this defect, including parts, labor, and miscellaneous costs. If you already paid for this repair, send the reimbursement request with paid receipts to warranty@hino.com.
