General Motors is recalling more than 38,000 Chevrolet Impala patrol cars in North America because the lower front control arms could fracture, increasing the risk of a crash, according to documents filed with the National Highway Traffic Safety Administration.
The recall affects Impala police vehicles from model years 2008 to 2012, including 36,413 in the United States and 1,713 in Canada.
A fracture of the control arms, which support a vehicle's wheels, can lead to loss of control, according to the NHTSA documents. Some tire "squeal" or "chirping" may be heard when turning at low speeds after a fracture.
The recall is expected to begin August 21.
