Lexus has formally submitted its recall for an engine issue

reported last week

. The recall involves 138,874 cars from a number of different models, including:

* 2007-2008 Lexus GS 350 and GS 350h

* 2008 Lexus GS 460

* 2006-2008 Lexus IS 350

* 2007-2008 Lexus LS 460, LS 460 L

* 2008 Lexus LS 600h L

The problem stems from a valve spring that could degrade and break, leading to the engine stalling while in motion. Lexus says the likelihood of this happening is 0.2%; however, the recall still compounds Toyota’s continuing quality issues.

The company will begin notifying owners via mail this month and will replace all valve springs for free. Owners can contact Lexus at 800-255-3987 or the National Highway Traffic Safety Administration at 888-327-4236.

2010 Subaru Legacy, Outback

The popular, redesigned Subaru Legacy sedan and Outback wagon have been included in another recall. This time, 73,698 vehicles built between Feb. 16, 2009, and April 12, 2010, are being addressed due to a fault on the wiring system in the steering column.

Possible defects could lead to malfunctioning front airbags, paddle shifters, cruise control, horn control and radio controls. You can find out if your car is included in the recall by checking the driver-side doorjamb, where a sticker lists the date of assembly.

Subaru said it would begin contacting owners this month. Owners can contact Subaru at 800-782-2783 or the National Highway Traffic Safety Administration at 888-327-4236.
