Recall 23V451 affects 170 2021-2025 Lion LION6 and LION8 vehicles for loose high-voltage hardware. Repair is free at any franchised Lion dealer.
Lion is recalling 170 2021-2025 LION6 and LION8 vehicles because loose hardware inside the high-voltage distribution unit or direct current junction box can touch electrical terminals and cause a short circuit. That short circuit can cut steering assistance or drive power and reduce braking power, which increases crash risk, and Lion dealers will complete the repair free of charge.

What's wrong?
The HVDU and DCJB enclosure on 2021-2025 Lion LION6 and LION8 vehicles houses high-voltage electrical connections. The HVDU, or high-voltage distribution unit, routes power through the vehicle's electric drive system. The DCJB, or direct current junction box, joins direct-current circuits so power reaches the components that need it.
In affected vehicles, hardware inside those enclosures can loosen. If a loose fastener or related hardware moves far enough to touch an electrical terminal, it can create a short circuit. Lion's repair updates the hardware inside the HVDU and DCJB and uses updated torque, which means the fasteners are tightened to the corrected specification.
There is no warning sign before failure. The first sign can be a high-voltage shutdown after the loose hardware contacts a terminal. An owner or fleet operator should describe the issue to Lion service as loose hardware inside the HVDU or DCJB enclosure.
Who's affected?
Covers LION6 and LION8 trucks from the 2021 through 2025 model years, all using the same high-voltage distribution unit and DC junction box enclosure.

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?
A short circuit can shut down the high voltage circuit, which can cut steering assist or drive power and reduce braking power. That loss of assistance gives the driver less control and increases the risk of a crash. If your VIN is included, schedule the repair soon and drive cautiously until it is complete. Repair is free at any franchised Lion dealer.
What should I do?
- Check your VIN to confirm your 2021-2025 Lion LION6 or LION8 is included in this recall.
- Contact Lion customer service at 1-855-546-6706 to schedule the free hardware replacement.
- Schedule the HVDU or DCJB hardware replacement that keeps loose hardware from shorting electrical terminals.
- Bring the owner notice if you have it. If not, reference recall number 23V451 when you call.
- Drive cautiously until the repair is complete. Leave extra following distance and stop using the vehicle if steering assist, drive power, or braking power changes.
What happens at the repair
At the dealer, a Lion technician replaces the loose hardware inside the high-voltage distribution unit or direct current junction box enclosure. The replacement parts and labor are free under the recall. Lion has a general reimbursement plan on file for documented repair costs paid before the recall notice. If you already paid for the same hardware repair before owner letters were mailed, ask Lion customer service how to submit the paperwork under that plan.
