What this means for you

Our assessment, not the agency’s: severity 4/5 (Severe).

The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall involves a structural vehicle defect (electrical system) that explicitly increases the risk of a fire, meeting the criteria for a Severe rating.

Plain-English summary

Lonestar Specialty Vehicles is recalling certain 2021-2023 SV Hybrid Electric S22 terminal tractors. The recall addresses a defect in the Vehicle Control Unit (VCU) software that may disable the Battery Management System (BMS) isolation measurement feature. This failure prevents the detection of high-voltage battery pack malfunctions.

The defect increases the risk of a fire because the operator may remain unaware of a high-voltage battery pack malfunction. Lonestar Specialty Vehicles has released an over-the-air (OTA) VCU software update to correct the issue at no charge to the owner.
