Isuzu is recalling 19,479 2023-2024 Chevrolet Lcf 4500HG, Chevrolet Lcf 5500XG, and N-Series vehicles under recall 23V564 because incorrectly sized wire seals can let water reach the engine ignition coil pack fuse holders and corrode the fuses.

What's wrong?
The main chassis harness on affected 2023-2024 Isuzu N-Series and Chevrolet Lcf trucks is the wiring bundle that carries electrical power and signals through the vehicle. In this recall, the affected area feeds the externally mounted engine ignition coil pack fuse holders. Those fuses protect the coil pack circuits that help the engine fire correctly.
The problem is the wire seal inside the fuse holder. It was built with the wrong opening size for one of the wires, so the seal does not grip the wire tightly enough. Water can enter the fuse holder, corrode the fuses, and interrupt power to the ignition coils. When that happens, the engine misfires and power drops.
Owners can see a steady Check Engine light, hear the engine misfire, and feel the vehicle shake or vibrate. The truck can also have reduced power, a fuel smell from the exhaust, then a flashing Check Engine light and a 5MPH speed derate, while power steering assist and power brake assist remain available.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific truck.
What's the safety risk?
Corrosion in the ignition coil pack fuses can cause an engine misfire and loss of power, increasing crash risk. Watch for a steady Check Engine light, engine shake or vibration, reduced power, or fuel smell from the exhaust. If those signs appear, stop driving and call the dealer. Repair will be free at any franchised Chevrolet dealer once Isuzu opens it.
What should I do?
- Check your VIN to confirm your 2023-2024 Isuzu Chevrolet Lcf 4500HG, Chevrolet Lcf 5500XG, N-Series, Chevrolet Lcf 3500HG, or Chevrolet Lcf 5500HG is included in this recall.
- Contact a franchised Chevrolet dealer to ask whether the free ignition-coil fuse-holder repair is open for your VIN.
- Call Isuzu customer service at 1-866-441-9638 with questions and reference recall number 23V564 (Isuzu recall V2305) when you call.
- Watch for misfire or loss of engine power until the repair is complete, and stop driving if the truck does not run normally.
- Bring the owner letter if Isuzu mailed one, or give the dealer recall number 23V564 at the service desk.
What happens at the repair
Once the final repair opens, a Chevrolet technician will replace both externally mounted engine ignition coil pack fuse holder assemblies on the chassis harness. Parts and labor are free under recall 23V564. The repair addresses water intrusion at the fuse holders that can corrode the fuses. Out-of-pocket repairs already paid are handled through the New Truck Warranty or Engine Emission Warranty, not through a separate reimbursement program. Ask the service desk how that warranty coverage applies if you have prior repair paperwork.
