The recall includes 2007-2008 Aston Martin DB9 Coupe, DB9 Volante, V8 Vantage Coupe, V8 Vantage Roadster, and DBS Coupe models.
In the affected models, a bolt securing the front suspension arm could crack, causing the lower control arm to move. "Movement of the lower control arm will influence the driver's control of the steering of the vehicle increasing the risk of a crash," states the official NHTSA summary report.
In Aston Martin's notification letter to NHTSA, the automaker says, "Dealers will be instructed to replace the front suspension lower control arm cam bolts with cam bolts of a known quality assured specification."
According to the automaker, a supplied bolt from a UK supplier was out of spec for hardness and thus prone to snap off. Less than one percent of the vehicles recalled actually have the condition, according to Aston, and it only affects cars built from March to September 2007.
Aston adds that the issue could also lead to suspension knock or, as it says in the letter "unusual steering response accompanied by metallic rattling."
It's been quite the season for luxury-car recalls. Just last week, BMW announced a recall of nearly 200,000 vehicles in North America, for a potential brake-system issue; and in July, Jaguar announced a recall of 2010-2011 XF and XK models for a potential stalling issue.
Aston Martin will begin notifying owners by October 18, 2010, or owners may call 888-923-9988 with any questions.
