The 2006 Maserati Quattroporte has two recalls, the more serious involving front suspension ball joints that can loosen and eventually separate, causing the suspension arm to break away from the vehicle and resulting in a sudden loss of steering and handling control.
The second recall covers the hydraulic power steering rack, where an internal o-ring can shift out of position during prolonged hard left turns. When this happens, power assist drops off and the steering wheel becomes significantly heavier, requiring much more effort to control the car and raising the risk of a crash.
At a glance
What can fail

What the fix does
Dealers will check that the ball joint nuts are properly tightened and will replace the suspension arms and hub carrier if needed.
