Washington, D.C. — Federal safety regulators have flagged more than 18,000 commercial vehicles across major heavy-duty nameplates, triggering urgent service campaigns that affect equipment nationwide. International Motors has issued a major safety recall covering certain 2023 through 2026 LT and RH model highway tractors due to a critical transmission software and hardware glitch involving the auto neutral function.
The core issue centers on the automated neutral system failing to properly recognize when the parking brake has been set. When this failure occurs, the transmission may remain engaged instead of shifting into neutral as designed, creating a dangerous rollaway hazard for drivers working around the vehicle. This specific International action alone impacts 11,418 units currently operating on freight lanes across the country, following an earlier safety campaign launched on November 25 that also targeted LT and RH configurations.
To fix the defect, authorized dealers are required to replace the quick-release valve located on the rear axle at zero cost to the fleet or owner-operator. International has assigned internal recall identifier 25524 to the campaign, and official notification letters are scheduled to land in mailboxes on January 19, 2026. Motor carriers can verify affected Vehicle Identification Numbers through manufacturer databases or by contacting customer support directly.
What This Means for Drivers
Unplanned shop time directly cuts into a CDL-A driver's weekly earnings and disrupts tight delivery schedules for OTR operators. Fleet managers must coordinate with local dealerships to schedule immediate valve replacements without stalling freight movement. Owner-operators carrying affected International units face mandatory service stops to clear the safety flag and maintain compliance.
Industry Reaction
Safety advocates and independent mechanics note that complex electronic integration in modern heavy-duty trucks continues to introduce unforeseen mechanical failures. While software updates and valve swaps fix the immediate danger, recurring recalls on newer model years place an undue administrative and financial burden on small carriers already operating on razor-thin margins.
Key Points
- International recalled 11,418 trucks spanning model years 2023 through 2026.
- Affected models include International LT and RH units due to auto neutral detection failures.
- Dealers will replace the rear axle quick-release valve at no charge to owners.
- Official owner notification letters are scheduled for release on January 19, 2026.
