Toyota (TM) has issued a recall for over 46,000 Tundra pickup trucks because they may have a stability issue due to a faulty axle shaft that could separate from the vehicle.

The recall affects certain 2022 Tundra gas-powered and hybrid pickups.

Toyota said the axle issue is a result of flange nuts on the axle shaft assemblies that can become loose over time and, in some instances, fall off. This could potentially cause one or both axle shaft sub-assemblies to separate from the truck’s axle housing, which could lead to loss of vehicle stability and brake performance.

If the axle shaft sub-assemblies were to separate from the axle housing, it could increase the risk of a crash, according to the automaker. Impacted Tundra truck owners may experience vibration, hear an abnormal noise, or observe leaking differential oil.

To repair the axle problem, Toyota dealers will inspect the rear axle assembly, tighten the axle flange nuts, and replace any damaged axle-related components, if required, at no charge to Tundra owners.

Recall notices are expected to be mailed out to the affected truck owners starting on July 15. Toyota said that it is “unable to estimate the percentage of the involved vehicles to contain the defect.”

Questions about the recall can be directed to Toyota customer service at 1-800-331-4331.

As of Friday at 1:17 p.m. ET, shares of Toyota were trading at $154.30, up 13 cents or 0.08%.
