ISUZU FTR

STEERING:LINKAGES:TIE ROD ASSEMBLY

Isuzu Motors Limited (Isuzu) is recalling certain 2025 FTR vehicles. The tie rod assemblies may contain ball studs that have been incorrectly heat-treated, which can cause them to break, and possibly result in tie rod failure.

Risk: Tie rod failure can cause a loss of vehicle steering control and increase the risk of a crash.

ELECTRICAL SYSTEM

Isuzu Motors Limited (Isuzu) is recalling certain 2019-2024 FTR, 2020-2024 Chevrolet LCF 6500XD, 2022-2024 FVR, and 2023-2024 Chevrolet LCF 7500XD vehicles equipped with a Mobileye Collision Warning System. The Mobileye camera cable may have been routed improperly, which can result in wiring damage and an overloaded electrical circuit.

Risk: Overloaded electrical circuits can overheat, increasing the risk of fire. In addition, wiring damage may cause a loss of turn signal, hazard lights, and/or collision system function, increasing the risk of a crash.

POWER TRAIN:AUTOMATIC TRANSMISSION

Isuzu Motors Limited (Isuzu) is recalling certain 2022 FTR vehicles equipped with Allison 2500RDS (FVR) transmissions. The transmission is missing the parking pawl.

Risk: There is no pawl to engage when the transmission shift lever is set to the park position, which could lead to the truck rolling away, increasing the risk of a crash.

FUEL SYSTEM, DIESEL:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain FTR and FVR trucks. The quick connector used to connect the fuel suction hose to the fuel inlet pipe of the engine is too large. The larger diameter of the quick connector may cause inadequate sealing, resulting in a fuel leak. In addition, the gap may cause air to be sucked into the fuel hose while the engine is running.

Risk: A fuel leak in the presence of an ignition source can increase the risk of a fire. Air intake into the fuel hose increases the risk of engine stalling, increasing the risk of a crash.

STEERING

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2018-2021 Isuzu FTR and 2018-2021 Chevrolet 6500XD vehicles. A bolt on the left front steering knuckle may come loose, resulting in an increased turning radius and difficulty steering to the left.

Risk: An unexpected change in turning radius and difficulty steering can increase the risk of a crash.

ELECTRICAL SYSTEM:STARTER ASSEMBLY

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2018-2021 FTR and Chevrolet 6500XD vehicles. The ground cable connecting the starter motor to the vehicle frame may break at the starter-side eyelet, resulting in an engine no-crank or slow-crank condition, causing the vehicle not to start.

Risk: If the cable is broken and repeated attempts are made to start the vehicle, the starter may ground through the steel braiding of the power steering hose, allowing it to heat up and possibly rupture, increasing the risk of a fire.

ELECTRICAL SYSTEM:WIRING

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2018-2020 FTR and Chevrolet 6500XD vehicles. The chassis wire harness outside the relay box may have been improperly routed, potentially allowing the harness to contact the suspension's leaf spring hanger bracket, allowing the harness to get chafed.

Risk: Depending on which wires get damaged, the vehicle can experience stalling and/or reduced functionality of the ABS, increasing the risk of a crash.

STEERING

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2018-2020 FTR and Chevrolet 6500XD vehicles. The jam nut for the steering stopper bolt on the left front knuckle may loosen and allow the bolt to back away from the steering knuckle, increasing the turning radius of the vehicle in a left turn.

Risk: If the vehicle's turning radius is increased, there is an increased risk of a crash.

ELECTRICAL SYSTEM:WIRING

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2017-2019 N-GAS HD and Chevrolet Low Cab Forward 3500 and 4500 vehicles and 2018-2019 Isuzu FTR and Chevrolet Low Cab Forward 6500XD vehicles. The power supply bolt in the relay box may not have been properly tightened during harness production at the supplier. This may lead to melting of the power wire and/or a loss of electrical power to the vehicle, which can lead to a stall.

Risk: A stall can increase the risk of a crash.
