Nissan has announced a voluntary safety recall of nearly 600,000 Frontier pickup trucks and Xterra sport-utility vehicles because of the risk that the steering shaft could crack due to corrosion.

No accidents have been reported associated with this problem. Most of the recalled cars are in the U.S.

Nissan found that the lower steering column joint can corrode, limiting steering movement. In extreme cases, the corrosion can lead to the cracking of the steering shaft, resulting in loss of control of the vehicle.

The joint and shaft will be replaced on about 303,000 Nissan Frontier trucks and 283,000 Xterra SUVs.

Additionally, Nissan is recalling about 18,500 Sentra sedans due to a faulty battery connection that could make starting the cars difficult and cause stalling at low speeds.
