Both the current and previous recall for the 3.4 V6 affects models made in Japan with Japanese V6 engines.6th gen 4runner’s engine is made in Japan (along with the rest of the truck), and the v6 in the tundra is made in Alabama and truck made in Texas. Totally different plants and processes. Nothing to worry about in my opinion.
There is something fundamentally wrong with their production process for this engine, and probably has something to do with cost savings when machining the block.
