Toyota is recalling about 752,000 Corolla and Matrix cars for issues with their airbag control modules and 270,000 Lexus ISs for a problem which could break their front windshield wipers. Both separate problems are the most recent in a chain of huge recalls to hit Toyota in recent months.

The difficulty: The Corolla and Matrix’s airbag control module is at risk of interference from other car parts and short-circuiting. If a quick circuit occurs in a single of the module’s circuit boards and generates enough heat, it may possibly warp or otherwise damage the airbag control module. If that occurs, it is able to trigger front airbags, the seat belt pretensioners, or both. If this occurs outside of a precise crash, it will probably cause injury or make it difficult to drive the auto.

The Fix: Toyota will add something called an electric signal filter to the module, which should prevent interference and short circuits. Toyota will notify owners of the affected cars with a letter “in the near future,” and the repairs are expected to take about an hour to finish. The service would be without cost. Customers can call Toyota at 1-800-331-4331 or visit www.toyota.com/recall for additional information.

Number of Vehicles Potentially Affected: 752,000 2003 and 2004 Corolla and Matrix vehicles.

Lexus is recalling select 2006-2012 IS sedans for issues with front windshield wipers.

The difficulty: The IS’ front wiper arm nuts will not be sufficiently tight. If the nut is loose and the wipers are buried under a heavy load of snow, the wipers couldn’t work.

The Fix: Toyota will replace the nuts and tighten them, in a repair which will take about half-hour to finish. The repair is freed from charge, and Lexus will notify affected car owners with a letter. Customers may also call Lexus at 1-800-255-3987 or visit www.lexus.com/recall for additional information.

Number of Vehicles Potentially Affected: 270,000 Lexus IS vehicles made between 2006 and 2012.
