Japan Recalls Four American Tundras for a Cracked Camshaft

Toyota filed a recall in Japan on November 12 for four Tundra pickups whose exhaust camshafts may have cracked during machining.

The four trucks are parallel imports, meaning they were brought into Japan privately rather than through Toyota’s own program for selling the US-built Tundra there, and they were built between January 22 and January 27, 2026. The part at issue is the right-side exhaust camshaft of the truck’s V engine. Toyota says insufficient control of the manufacturing process left it too weak, and that some of the parts have cracks that formed during machining. If those cracks grow with use, the camshaft can break and the engine can stall while the truck is being driven.

The details are in Toyota’s Japanese recall notice, filed as recall number 5903, with repairs beginning on November 13. The notice does not say how the problem was found or whether any failures have occurred. Creative Trend, which first flagged the filing, reported that no accidents or failures have been reported and that the issue was identified from information supplied by the truck’s home market.

Dealers in Japan will check the serial number of the camshaft on each truck and replace any that come from the affected batch, free of charge. Owners can look the trucks up under VINs running from VXKA75-X352186 to VXKA75-X352189.

The question for American owners is whether camshafts from the same batch went into trucks sold here, since the four recalled pickups are American-built Tundras and nothing in the Japanese notice limits the defect to export trucks. Toyota has not said. When we checked on November 12, NHTSA’s recall database listed only one recall for the 2026 Tundra, a label correction on a single truck, and nothing involving the camshaft.

The Toyota Report Take

Four trucks is a tiny recall, but the wording is what will catch the eye of Tundra owners who lived through the long machining-debris saga on the twin-turbo V6. A batch of camshafts cracked during machining is a production-control problem, and production-control problems rarely stop at four trucks that happened to be exported. If Toyota’s home market supplied the information, as the Japanese report says, a US filing covering trucks built around late January would be the logical next step, and owners of early 2026 builds should watch for one.
