GM says that no accidents of any kind have been attributed to the problem, but that it will begin sending notices to owners later this month and dealers will replace both front lower control arms. In an email, Chevrolet spokesman Alan Adler informed Autoblog that "There is no recall or any field action on non-police (civilian) Impalas now or in the works." Why is that? According to Adler, "Analysis was done to understand the durability in non-police Impalas and showed the control arms used in the base Impalas will exceed GM Engineering durability requirements."

DETROIT – General Motors is recalling 36,413 Chevrolet Impala Police Sedans from the 2008-2012 model years sold in the United States to replace the front lower control arms that support the vehicle's wheels. The safety recall does not include non-police Impala models.
If the front lower control arm fractures and separates from its handling bushing sleeve, sudden changes in vehicle handling and reduced steering control may result, depending on vehicle speed and road surface conditions.
GM knows of no crashes, injuries or deaths related to the condition. The Impala Police Sedan is sold to municipalities in the United States and Canada.
Dealers will replace the right-hand and left-hand front lower control arms. GM expects to begin mailing owner letters on Aug. 21, 2012.
