Toyota has recalled nearly 12,000 trucks and SUVs after discovering a missing vehicle roller guide on a manufacturing lane in its San Antonio, Texas plant. The recall was months in the making.

In June, a Toyota team member noticed damage on the interior sidewall of a new vehicle’s passenger-side tire. Looking back at equipment maintenance records, a May report specified a disengaged roller guide. As it turns out, the roller was not reinstalled. Once removed, an exposed bracket could have caused damage to vehicles rolling past it down the assembly line.

The automaker says it began inspecting vehicles built between April 30 and July 10, 2024, in various holding areas. During these inspections, the team located another car that matched the tire damage of the initial discovery.

The exposed assembly line bracket seems to have gouged the inner sidewall of passenger-side tires. The structural damage could cause sudden loss of tire pressure.

The automaker reports potentially 11,890 affected vehicles, including the 2024 Sequoia Hybrid, Tundra, and Tundra Hybrid. Toyota says the estimated number of problematic tires is “unknown.”

On October 9, Toyota decided to enter a voluntary recall over the problem. To date, it reports no Toyota Field Technical Reports or warranty claims related to this issue.

In any case, Toyota will send letters to the owners of 2024 Toyota Sequoia Hybrid, Tundra, and Tundra Hybrids manufactured in Texas between April 30 and July 10.

If a dealer inspection reveals damage to the sidewall, Toyota will replace the tire free of charge. Owners will be notified between November 30 and December 14, 2024.
