Toyota has announced two recalls related to some of the body-on-frame trucks it sells in the United States.

The larger of the two concerns the 2018 Tundra pickup and Sequoia sport-utility vehicle. The problem lies with the vehicle’s electronic control systems, which may incorrectly place the vehicle in diagnostic function and disable the stability control system.

Since that can potentially increase the possibility of a crash, the owners of some 65,000 Tundras and Sequoias are being notified to bring their vehicles into their local dealers to have their software updated.

A smaller recall has also been issued for certain 2017 Tundras with second-row seating, which refers to the Double Cab and CrewMax configurations. On these vehicles, the bolts securing the left rear seat may not have been properly fastened, so dealer technicians are being instructed to inspect and tighten them on an estimated 8,800 trucks.

Though the Sequoia, with little over 12,000 units sold last year, is hardly a big seller for Toyota, the Tundra is, as last year the automaker sold over 116,000 examples of its pickup in the United States. That puts the big truck ahead of the Sienna and just behind the 4Runner in Toyota’s truck sales chart, but far away from the nearly 200,000 Tacomas Toyota shifted in the States in 2017.

Both pickups were far outsold by the RAV4 (400,000+ units) and the Highlander (215k units) that contributed to 1.1 million trucks, sport-utes, crossovers and minivans that Toyota sold in America last year.

That’s more than the 910,000 passenger cars it moved last year, and far more than the 104k upscale Lexus models it delivered over the same period. So, SUVs and pickup trucks still reign supreme in the second largest market in the world, and unless there’s a sudden spike in oil prices, we can’t see this changing any time soon.
