Toyota has announced a voluntary safety recall on certain RAV4s and 2010 Lexus HS 250hs that were sold in the United States, the U.S. arm of Toyota Motor Corp. (NYSE: TM) said in a news release. Find out here if your Toyota or Lexus is part of the recall.

"Toyota has determined that if the nuts on the rear suspension arm are not tightened following the proper procedure and torque specification during a rear wheel alignment service, excessive play may occur at the threaded portion of the arm, followed by rust formation," the company said on its website. "If this were to occur, the threaded portion of the rear suspension arm may wear and cause the arm to separate."

The recall affects about 760,000 Toyota RAV4 models from 2006 through early 2011 and approximately 180,000 Lexus HS 250h models from 2010 that were sold in the United States.
