This roundup has a variety of recalls, from major to minor, affecting hundreds of thousands of cars to just a few hundred. The largest recall on a volume basis, is Toyota's recall of more than 700,000 2006-2011 RAV4 SUVs and 2010 Lexus HS250h hybrid sedans for faulty rear-wheel tie-rod adjustment nuts. Improper tightening of the rear tie rods could cause unwanted movement and rust causing thread damage and possible failure. Toyota is also recalling 133,000 2006-2008 Lexus RX and 2006-2010 Toyota Highlander Hybrid models for defective transistors within the hybrid inverter system, causing the vehicles to go into limp-home mode, resulting in reduced performance, and in some cases, causing the vehicle to come to a complete stop.

Volvo is recalling 7767 models, including the 2014 XC60 and XC70 equipped with a keyless ignition system. A bug in the electronics module could result in the front windshield wipers running continuously with the ignition on. The defect could also affect operation of the vehicles' turn signals, and headlights.

Finally, Honda is recalling 270 2013 Pilot models for faulty pistons. Some models received pistons with inadequate heat treatment, which could result in premature wear and engine seizing. Affected models will receive a new engine short block.

The recall campaign for the Toyota tie-rods will start in September 2013 and run through February 2014, due to a parts shortage. Owners will receive a preliminary notification, and a secondary notification when parts become available in their area. The RX and Highlander Hybrid will receive notification by mail. The Honda recall will begin on September 16.

Toyota and Lexus owners can call 800-331-4331, Volvo owners can call 800-458-1552, and Honda owners can call 800-999-1009. For more information on recalls for all vehicles, owners can call the National Highway Traffic Safety Administration's Vehicle Safety Hotline at 888-327-4236.
